Rotator cuff pathology is the main cause of shoulder pain and dysfunction in older adults. When a rotator cuff tear involves the subscapularis tendon, the symptoms are usually more severe and the prognosis after surgery must be guarded. Isolated subscapularis tears represent 18% of all rotator cuff tears and arthroscopic repair is a good alternative primary treatment. However, when the tendon is deemed irreparable, tendon transfers are the only option for younger or high-functioning patients. The aim of this review is to describe the indications, biomechanical principles, and outcomes which have been reported for tendon transfers, which are available for the treatment of irreparable subscapularis tears. The best tendon to be transferred remains controversial. Pectoralis major transfer was described more than 30 years ago to treat patients with failed surgery for instability of the shoulder. It has subsequently been used extensively to manage irreparable subscapularis tendon tears in many clinical settings. Although pectoralis major reproduces the position and orientation of the subscapularis in the coronal plane, its position in the axial plane – anterior to the rib cage – is clearly different and does not allow it to function as an ideal transfer. Consistent relief of pain and moderate recovery of strength and function have been reported following the use of this transfer. In an attempt to improve on these results, latissimus dorsi tendon transfer was proposed as an alternative and the technique has evolved from an open to an arthroscopic procedure. Satisfactory relief of pain and improvements in functional shoulder scores have recently been reported following its use. Both pectoralis minor and upper trapezius transfers have also been used in these patients, but the outcomes that have been reported do not support their widespread use.

Aims. To systematically review the efficacy of split tendon transfer surgery on gait-related outcomes for children and adolescents with cerebral palsy (CP) and spastic equinovarus foot deformity. Methods. Five databases (CENTRAL, CINAHL, PubMed, Embase, Web of Science) were systematically screened for studies investigating split tibialis anterior or split tibialis posterior tendon transfer for spastic equinovarus foot deformity, with gait-related outcomes (published pre-September 2022). Study quality and evidence were assessed using the Methodological Index for Non-Randomized Studies, the Risk of Bias In Non-Randomized Studies of Interventions, and the Grading of Recommendations Assessment, Development and Evaluation. Results. Overall, 17 studies (566 feet) were included: 13 studies used clinical grading criteria to report a postoperative ‘success’ of 87% (75% to 100%), 14 reported on orthotic use with 88% reduced postoperative use, and one study reported on ankle kinematics improvements. Ten studies reported post-surgical complications at a rate of 11/390 feet (2.8%), but 84 feet (14.8%) had recurrent varus (68 feet, 12%) or occurrence of valgus (16 feet, 2.8%). Only one study included a patient-reported outcome measure (pain). Conclusion. Split tendon transfers are an effective treatment for children and youth with CP and spastic equinovarus foot deformities. Clinical data presented can be used for future study designs; a more standardized functional and patient-focused approach to evaluating outcomes of surgical intervention of gait may be warranted.

Aims. Favourable short-term outcomes have been reported following latissimus dorsi tendon transfer for patients with an irreparable subscapularis (SSC) tendon tear. The aim of this study was to investigate the long-term outcomes of this transfer in these patients. Methods. This was a retrospective study involving 30 patients with an irreparable SSC tear and those with a SSC tear combined with a reparable supraspinatus tear, who underwent a latissimus dorsi tendon transfer. Clinical scores and active range of motion (aROM), SSC-specific physical examination and the rate of return to work were assessed. Radiological assessment included recording the acromiohumeral distance (AHD), the Hamada grade of cuff tear arthropathy and the integrity of the transferred tendon. Statistical analysis compared preoperative, short-term (two years), and final follow-up at a mean of 8.7 years (7 to 10). Results. There were significant improvements in clinical scores, in the range and strength of internal rotation and aROM compared with the preoperative values in the 26 patients (87%) who were available for long-term follow-up. These improvements were maintained between short- and long-term follow-ups. Although there was a decreased mean AHD of 7.3 mm (SD 1.5) and an increased mean Hamada grade of 1.7 (SD 0.5) at final follow-up, the rate of progression of cuff tear arthropathy remained low-grade. Comparison between the isolated SSC and combined SSC and reparable supraspinatus tear groups showed no significant differences. At final follow-up, one patient (3.8%) had undergone revision surgery to a reverse shoulder arthroplasty (RSA). No neurological complications were associated with the procedure. Conclusion. Latissimus dorsi transfer for an irreparable SSC tendon tear resulted in a significant clinical improvement, particularly in pain, range and strength of internal rotation and aROM, which were maintained over a mean of 8.7 years following surgery. Given that this was a long-term outcome study, there was a low-grade progression in the rate of cuff tear arthropathy. Thus, the long-term clinical efficacy of latissimus dorsi tendon transfer in patients with irreparable SSC was confirmed as a joint-preserving procedure for these patients, suggesting it as an effective alternative to RSA in young, active patients without degenerative changes of the glenohumeral joint.

Aims. Since long-term outcome of teres major tendon transfer surgery for irreparable posterosuperior rotator cuff (RC) tears is largely unknown, the primary aim of this study was to evaluate the long-term outcome of the teres major transfer. We also aimed to report on the results of a cohort of patients with a similar indication for surgery that underwent a latissimus dorsi tendon transfer. Patients and Methods. In this prospective cohort study, we reported on the long-term results of 20 consecutive patients with a teres major tendon transfer for irreparable massive posterosuperior RC tears. Additionally, we reported on the results of the latissimus dorsi tendon transfer (n = 19). The mean age was 60 years (47 to 77). Outcomes included the Constant score (CS), and pain at rest and during movement using the Visual Analogue Scale (VAS). Results. At a mean of ten years (8 to 12) following teres major transfer, the CS was still 23 points (95% confidence interval (CI) 14.6 to 30.9, p < 0.001) higher than preoperatively. VAS for pain at rest (21 mm, 95% CI 4.0 to 38.9, p = 0.016) and movement (31 mm, 95% CI 16.0 to 45.1, p < 0.001) were lower than preoperatively. We also found an increase in CS (32 points, 95% CI 23.4 to 40.2, p < 0.001) and reduction of pain (26 mm, 95% CI 9.9 to 41.8, p = 0.001) six years after latissimus dorsi transfer. Conclusion. Teres major tendon transfer is a treatment option to gain shoulder function and reduce pain in patients with an irreparable posterosuperior RC tear at a mean follow-up of ten years. The teres major tendon might be a valuable alternative to the commonly performed latissimus dorsi tendon transfer in the treatment of irreparable posterosuperior RC tears.

Background:. Massive rotator cuff tear can cause functional disability due to instability and degenerative changes of the shoulder joint. In patients with massive irreparable rotator cuff tear, tendon transfer is often used as the salvage procedure. Latissimus dorsi and pectoris major transfer are technically demanding procedures and may incur complications. The biceps tendon transfer may provide a biologically superior tissue patch that improves the biomechanics of the shoulder joint in patients with irreparable rotator cuff tear. This study evaluated the functional outcomes of biceps tendon transfer for irreparable rotator cuff tear in 6 patients with two years and longer follow-up. Methods:. Between September 2006 and October 2011, 50 patients with 50 shoulders underwent surgical repair for MRI confirmed rotator cuff tear. Among them, six patients with massive irreparable rotator cuff tear were identified intraoperatively, and underwent proximal biceps tendon transfer to reconstruct the rotator cuff tear. The biceps tendon was tenodesed at the bicipital groove, and the proximal intra-articular portion of the biceps tendon was transected. The biceps graft was fanned out and the distal end fixed to the cancellous trough around the greater tuberosity with suture anchor. The anterior edge was sutured to the subscapularis and the posterior edge to the infraspinatus tendon or supraspinatus if present. Postoperative managements included sling protection and avoidance of strenuous exercises for 6 weeks, and then progressive rehabilitation until recovery. Results:. The evaluation parameters included VAS pain score, UCLA score, Constant score and AHES score, and X-rays of the shoulder. At follow-up of 25.3 ± 25.0 (range 22 to 63) months, the mean VAS pain score decreased from 9.3 ± 0.8 preoperatively to 1.7 ± 1.4 postoperatively (p < 0.001). All patients presented with significant improvements in pain and function of the shoulder for daily activities after surgery, however, only one patient achieved excellent results. There is no correlation of functional outcome with age, gender and body mass index. There was no infection or neurovascular complication. Discussion:. The biceps transfer provides soft tissue coverage of the humeral head, and restores the superior stability of the shoulder joint. The transferred biceps tendon also improves the mechanics and increases the compression force of the humeral head to the glenoid fossa. The results of the current study showed significant pain relief and improvement of shoulder function after biceps tendon transfer for irreparable rotator cuff tear. Conclusion:. Biceps tendon transfer is effective in the management of massive irreparable rotator cuff tear. The procedure is technically accessible with minimal surgical risks

Progressive collapsing foot deformity (PCFD) is a complex foot deformity with varying degrees of hindfoot valgus, forefoot abduction, forefoot varus, and collapse or hypermobility of the medial column. In its management, muscle and tendon balancing are important to address the deformity. Peroneus brevis is the primary evertor of the foot, and the strongest antagonist to the tibialis posterior. Moreover, peroneus longus is an important stabilizer of the medial column. To our knowledge, the role of peroneus brevis to peroneus longus tendon transfer in cases of PCFD has not been reported. This study evaluates patient reported outcomes including pain scores and any associated surgical complications for patients with PCFD undergoing isolated peroneus brevis to longus tendon transfer and gastrocnemius recession. Patients with symptomatic PCFD who had failed non-operative treatment, and underwent isolated soft tissue correction with peroneus brevis to longus tendon transfer and gastrocnemius recession were included. Procedures were performed by a single surgeon at a large University affiliated teaching hospital between January 1 2016 to March 31 2021. Patients younger than 18 years old, or undergoing surgical correction for PCFD which included osseous correction were excluded. Patient demographics, medical comorbidities, procedures performed, and pre and post-operative patient related outcomes were collected via medical chart review and using the appropriate questionnaires. Outcomes assessed included Visual Analogue Scale (VAS) for foot and ankle pain as well as sinus tarsi pain (0-10), patient reported outcomes on EQ-5D, and documented complications. Statistical analysis was utilized to report change in VAS and EQ-5D outcomes using a paired t-test. Statistical significance was noted with p<0.05. We analysed 43 feet in 39 adults who fulfilled the inclusion criteria. Mean age was 55.4 ± 14.5 years old. The patient reported outcome mean results and statistical analysis are shown in Table one below. Mean pre and post-operative foot and ankle VAS pain was 6.73, and 3.13 respectively with a mean difference of 3.6 (p<0.001, 95% CI 2.6, 4.6). Mean pre and post-operative sinus tarsi VAS pain was 6.03 and 3.88, respectively with a mean difference of 2.1 (p<0.001, 95% CI 0.9, 3.4). Mean pre and post-operative EQ-5D Pain scores were 2.19 and 1.83 respectively with a mean difference of 0.4 (p=0.008, 95% CI 0.1, 0.6). Mean follow up time was 18.8 ± 18.4 months. Peroneus brevis to longus tendon transfer and gastrocnemius recession in the management of symptomatic progressive collapsing foot deformity significantly improved sinus tarsi and overall foot and ankle pain. Most EQ-5D scores improved, but did not reach statistically significant values with the exception of the pain score. This may have been limited by our cohort size. To our knowledge, this is the first report in the literature describing clinical results in the form of patient reported outcomes following treatment with this combination of isolated soft tissue procedures for the treatment of PCFD.

We reviewed 11 patients who had been treated between January 1986 and June 1994 for severe foot injuries by tendon transfer with microvascular free flaps. Their mean age was 5.6 years (3 to 8). Five had simultaneous tendon transfer and a microvascular free flap and six had separate operations. The mean interval between the tendon transfer and the microvascular free flap was 5.8 months (2 to 15) and the mean time between the initial injury and the tendon transfer was 9.6 months (2 to 21). The anterior tibial tendon was split in five of six cases. The posterior tibial tendon was used three times and the extensor digitorum longus tendon twice. The mean follow-up was 39.7 months (24 to 126). There were nine excellent and two good results. Postoperative complications included loosening of the transferred tendon (2), plantar flexion contracture (1) mild flat foot deformity (1) and hypertrophic scars (2). We recommend tendon transfer with a microvascular free flap in children with foot injuries combined with nerve injury and extensive loss of skin, soft tissue and tendon

Introduction:. Peroneal muscle weakness is a common pathology in foot and ankle surgery. Polio, charcot marie tooth disease and spina bifida are associated with varying degrees of peroneal muscle paralysis. Tibialis Posterior, an antagonist of the peroneal muscles, becomes pathologically dominant, causing foot adduction and contributes to cavus foot posture. Refunctioning the peroneus muscles would enhance stability in toe off and resist the deforming force of tibialis posterior. This study determines the feasibility of a novel tendon transfer between peroneus longus and gastrocnemius, thus enabling gastrocnemius to power a paralysed peroneus tendon. Method:. 12 human disarticulated lower limbs were dissected to determine the safety and practicality of a tendon transfer between peroneus longus and gastrocnemius at the junction of the middle and distal thirds of the fibula. The following measurements were made and anatomical relationships quantified at the proposed site of the tendon transfer: The distance of the sural nerve to the palpable posterior border of the fibula; the angular relationship of the peroneus longus tendon to gastrocnemius and the achilles tendon; the surgical field for the proposed tendon transfer was explored to determine the presence of hazards which would prevent the tendon transfer. Results:. The mean angle between the tendons of peroneus longus and gastrocnemius/achilles tendon was 3°. The sural nerve lies on average 30 mm posterior to the palpable posterior border of the fibula. There were no significant intervening structures to prevent the proposed tendon transfer. Conclusion:. The line of action of peroneus longus and gastrocnemius are as near parallel as to be functionally collinear. The action of gastrocnemius may be harnessed to effectively power a paralysed peroneus longus tendon, without significant loss of force owing to revectoring of forces. The surgical approach to effect such a tendon transfer is both safe and practical

Purpose. This study aimed to objectively define gait derangements and changes before and after Tibialis Anterior Tendon Transfer surgery in a group of patients treated using the Ponseti method. Methods. 21 feet in 13 patients with Ponseti treated clubfoot who showed supination in swing on clinical examination, underwent gait analysis before, and approximately 12 months after, Tibialis Anterior Tendon transfer. 3–4 weekly casts were applied prior to the surgery, which was performed by transfer of the complete TA tendon to the lateral cuneiform. A parental satisfaction questionnaire was also completed. Results. In all but one patient, increased supination in swing phase was confirmed on pre-operative gait analysis, with EMG evidence of poor Tibialis Anterior modulation through-out the gait cycle. Post-operatively all patients showed improved positioning at initial contact, with heel strike and an absence of supination, and a decrease in swing phase supination. In all patients, knees were overly flexed at initial contact, some continuing through stance phase; there was no change seen postoperatively. All parents reported marked improvements in gait and activity level post-operatively. Conclusion. Gait analysis can be useful to confirm the need for tibialis anterior tendon transfer. Improved post-operative gait patterns seen by parents and clinicians can be related to objective improvements seen during gait analysis, confirming the benefit of tibialis anterior tendon transfer in appropriate patients

Although it is generally accepted that surgical treatment is the treatment of choice in chronic TA ruptures, therapeutic options are difficult. Traditional options include grafts (natural, allografts and synthetic grafts) and end to end repair. Natural grafts described include fascia lata and plantaris tendon. Synthetic materials such as Dacrongrafts, Marlex mesh and carbon fibers have been used. There are significant complications from graft and end to end repair. These include wound necrosis, delayed union, infection, foreign body reaction and devastating tissue loss. Also functional results are suboptimal after delayed reconstruction. Tendon transfer is another method that has been described for the treatment of these injuries. The tendons used were the flexor hallucis lomgus, flexor digitorum longus and the peronei . The FHL tendon transfer is considered advantageous to other tendon transfers because it is stronger, its axis of force is close to that of the TA and harvesting the tendon is easy and unlikely to cause any complications. We report excellent results following four operations in three patients treated with flexor hallucis longus tendon transfer for chronic Achilles tendon ruptures. All patients were on long term steroid treatment and an end to end repair would have been associated with a high complication rate. We believe that FHL transfer to replace the TA is a low morbidity alternative which gives good to excellent results in individuals with low to moderate demand

Objective: To assess the efficacy of split Tibialis Posterior tendon transfers for the treatment of spastic equino-varus feet. Materials and Methods: Fourteen patients with 14 spastic equino-varus feet underwent split Tibialis Posterior tendon transfers. The spasticity was due to cerebral palsy, ataxia telangiectasia and traumatic brain injury. All the patients had Ashworth 1–3 spasticity, and the forefoot was correctible in equinus. Evaluation of the results was by grading of the shape of the feet, ambulation, pain and brace tolerance. Results: One patient was lost to follow-up after an excellent primary result. Twelve patients had good or excellent results, and one patient had a fair result due to partial recurrence of the deformity. No complications were encountered. Conclusions: Split Tibialis Posterior tendon transfer is a safe and efficacious procedure for the treatment of spastic equino-varus feet. Good alignment of the treated feet allows comfortable brace and shoe wear. Patient selection is important in order to avoid over-correction or recurrence of the deformity

Latissimus dorsi tendon transfer (LDTT) is technically challenging. In order to clarify the local structural anatomy, we undertook a morphometric study using six complete cadavers (12 shoulders). Measurements were made from the tendon to the nearby neurovascular structures with the arm in two positions: flexed and internally rotated, and adducted in neutral rotation. The tendon was then transferred and measurements were taken from the edge of the tendon to a reference point on the humeral head in order to assess the effect of a novel two-stage release on the excursion of the tendon. With the shoulder flexed and internally rotated, the mean distances between the superior tendon edge and the radial nerve, brachial artery, axillary nerve and posterior circumflex artery were 30 mm (26 to 34), 28 mm (17 to 39), 21 mm (12 to 28) and 15 mm (10 to 21), respectively. The mean distance between the inferior tendon edge and the radial nerve, brachial artery and profunda brachii artery was 18 mm (8 to 27), 22 mm (15 to 32) and 14 mm (7 to 21), respectively. Moving the arm to a neutral position reduced these distances. A mean of 15 mm (8 to 21) was gained from a standard soft-tissue release, and 32 mm (20 to 45) from an extensile release. These figures help to define further the structural anatomy of this region and the potential for transfer of the latissimus dorsi tendon. Cite this article: Bone Joint J 2013;95-B:517–22

Common peroneal nerve (CPN) palsy has been reported to be the most frequent lower extremity palsy characterized by a supinated equinovarus foot deformity and foot drop. Dynamic tendon transposition represents the gold standard for surgical restoration of dorsiflexion of a permanently paralyzed foot. Between 1998 and 2005, we operated on 16 patients with traumatic complete CPN palsy. An osseous tunnel is drilled from anterior tibialis tendon (ATT) bony insertion through the cuneiform bones in the direction of the third cuneiform, through which the ATT is extracted and then pulled proximally under the extensor retinaculum. New ATT origin on the third cuneiform is therefore created. A double tendon transfer is then performed with a direct tendon-to-tendon suture at the distal third of the leg between the rerouted ATT and the posterior tibialis tendon (PTT) (transposed anteriorly through interosseous membrane) and between the flexor digitorum longus tendon (FDL), similarly transposed and sutured side-to-side with the extensor digitorum longus and extensor hallucis longus tendons. This second transfer strengthens ankle dorsiflexion and reanimates toe extension. All 16 patients were reviewed at a minimum followup of 24 months. Results were assessed using the Stanmore system questionnaire and were classified as excellent in eight, good in five, fair in two, and poor in one. In all cases, transosseous rerouting of the ATT provided a sufficient tendon length, which permitted tendon-to-tendon suturing between the ATT and PTT to be performed proximal to the extensor retinaculum eliminating tendon length-related problems. The new origin of the ATT at the third cuneiform was confirmed to be the optimal traction line to achieve maximum dorsiflexion with minimal imbalance in accompanying pronation and supination. Double tendon transfer also avoids not only drop of the toes, but also allows some extension of the hallucis. Postoperative static and dynamic baropodometric evaluations also were performed showing an overall satisfying progression of gait characterized by the absence of external overload in toe plantar flexion and by reduction of foot contact time with the ground with improvement of heel contact and pushoff phase with evidence of a longer step. The novelty of our proposed technique is that of moving the insertion of the recipient tendon (ATT) toward the donor transferred tendon (PTT) and not the contrary, providing an appropriate direction of pull with adequate length and fixation. For treatment of complete CPN palsy, transosseous rerouting to the third cuneiform of the ATT and dual transfer of the PTT and FDL tendons is a reliable method to restore balanced foot and toe dorsiflexion producing a normal gait without the need for orthoses

Surgical repair of posterosuperior rotator cuff tears has a poorer outcome and a higher rate of failure compared with repairs of supraspinatus tears. In this prospective cohort study 28 consecutive patients with an irreparable posterosuperior rotator cuff tear after failed conservative or surgical treatment underwent teres major tendon transfer. Their mean age was 60 years (48 to 71) and the mean follow-up was 25 months (12 to 80). The mean active abduction improved from 79° (0° to 150°) pre-operatively to 105° (20° to 180°) post-operatively (p = 0.011). The mean active external rotation in 90° abduction improved from 25° (0° to 70°) pre-operatively to 55° (0° to 90°) post-operatively (p < 0.001). The mean Constant score improved from 43 (18 to 78) pre-operatively to 65 (30 to 86) post-operatively (p < 0.001). The median post-operative VAS (0 to 100) for pain decreased from 63 (0 to 96) pre-operatively to 5 (0 to 56) post-operatively (p < 0.001). In conclusion, teres major transfer effectively restores function and relieves pain in patients with irreparable posterosuperior rotator cuff tears and leads to an overall clinical improvement in a relatively young and active patient group with limited treatment options.

Introduction and Aims: The role of tendon transfer in progressive hereditary motor sensory neuropathy (CMT) is controversial. This paper examines a large single surgeon cohort and reviews the surgical outcome of tendon transfers against a large group of CMT patients represented by the Australian CMT Health Survey 2001. Method: A retrospective review was carried out in 19 patients (36 feet) with CMT, managed surgically by a single author (GW). Functional outcomes were measured using standard tools such as SF36, American Orthopaedic Foot and Ankle Score (AOFAS) rating scale, and a clinical review including a specially designed questionnaire. Quality of life and functional outcome has been compared with the Australian CMT Health Survey 2001 in 324 patients. Results: Nineteen patients were managed with tendon transfers, typically by flexor to extensor transfer of toes, combined with peroneus longus release and transfer, and tibialis posterior transfer. The Levitt classification of the objective results of surgery rates 79% of patients as having good-excellent outcomes. Eighty-nine percent of patients report an improvement overall with surgery, specifically 53% report improvement in pain, 79% feel their gait has benefited, and 58% report an improvement in the appearance of their foot deformity, as a direct result of their surgery. All patients reviewed would recommend similar surgery to others, and 95% of those surveyed wished they had their surgery much earlier (months to years). The AOFAS clinical rating system for ankle-hindfoot showed an average improvement of 39.7 points out of 100. In general patients treated by this method were improved when considered against a larger cohort both in quality of life measures and functional outcome. This combination was not always successful and a small number of disappointed patients were identified. Conclusion: Tendon transfer in the younger patient has a role in treating flexible deformity in CMT and improving quality of life. Traditionally surgery has been advised by means of arthrodesis in patients with more advanced fixed deformity and pain due to secondary osteoarthritis. This paper study shows that patients may benefit at an earlier stage in the progression of their disease by tendon transfer

Massive, irreparable rotator cuff tears occur in about 15% of patients with ruptures of the rotator cuff tendons. There is no consistently agreed management for irreparable rotator cuff tears, however, latissimus dorsi tendon transfer is a recognised technique. We aimed to review the functional outcome of patients undergoing this operation at a single tertiary referral centre. Fourteen latissimus dorsi transfer procedures in thirteen patients from May 2007 to May 2008 were retrospectively reviewed. The mean age of patients undergoing the procedure was fifty nine years. All patients were confirmed to have massive, irreparable (>5cm) rotator cuff tears as determined by MRI or ultrasound. Modified Constant scores (assessing shoulder pain, functional activity and movement) determined pre-operatively and post latissmus dorsi transfer were compared. The mean duration of follow up was 12 months. The mean Modified Constant Score (maximum = 75) improved from 23 points pre-operaively to 52 points post latissimus dorsi transfer (p < 0.05). All patients had improvement in shoulder pain following the operation. There was a trend for younger patients to have greater improvement in functional activity and shoulder movement. From our series, latissimus dorsi transfer is effective at improving functional outcomes in patients with massive, irreparable rotator cuff tears, especially in younger age groups

Background: Neglected ruptures of the tendoachilles pose a difficult surgical problem. Intervening scar tissue has to be excised which cannot be repaired by end-to-end anastamosis. Several techniques for reconstruction of chronic ruptures have been described. The flexor hallucis longus (FHL) tendon transfer is considered advantageous over other tendon transfers. One disadvantage of FHL is it has limited excursion. There are no data to determine the optimal positioning of the FHL tendon to the calcaneum. Materials and Methods: Two computer programmes (MSC.visualNastran Desktop 2002™ and Solid Edge® V19 were used to generate a human ankle joint model. This model is able to reproduce dorsi- and plantarflexion. Different attachment points of FHL tendon transfer to the calcaneum were investigated. Results: The lowest muscle force to produce plantarflexion (single stance heel rise) was 1355N. Plantarflexion increased for a more anterior attachment point. The maximal plantarflexion was 33.4° for anterior attachment and 24.4° for posterior attachment. There was no significant difference in these figures when the attachment point was moved to either a medial or lateral position. Clinical relevance: Optimal FHL tendon transfer positioning is a compromise between achieving plantarflexion for normal physiological function versus the force generating capacity and limited excursion of FHL. A more posterior attachment point is advantageous in terms of power. The range of motion is 10° less than when attachment is more anterior, the arc of motion (24.4°) is still physiological. We recommend that FHL is transferred to the calcaneum in a posterior position

Introduction. The delayed presentation of Achilles tendon rupture is common, and is a difficult problem to manage. A number of surgical techniques have been described to treat this problem. We describe the use of Flexor Hallucis Longus (FHL) transfer to augment the surgical reconstruction of the delayed presentation of achilles tendon rupture. Materials and Methods. Fourteen patients with chronic tendo-Achilles rupture, presenting between April 2008 and December 2010, underwent surgical reconstruction and FHL transfer. Surgery was performed employing standard operative techniques, with shortening of the Achilles tendon and FHL transfer into the calcaneum with a Biotenodesis screw (Arthrex). VISA-A scores were performed preoperatively and six months postoperatively. Complication data was collected by review of the electronic patient record and direct patient questioning. Results. One patient died of an unrelated cause shortly before outcome scoring, and another patient was excluded because casting in the preoperative period prevented accurate scoring, although he achieved a good post-treatment score. Analysis was therefore carried out on twelve patients. Eleven of the twelve patients had significant improvement in their VISA-A score, with a mean improvement in score of 30 (p < 0.05). There were no significant complications in any of the patients. Conclusion. Our results show that FHL transfer in the management of chronic Achilles tendon rupture is a good, safe and reliable technique. There is excellent improvement in the mean VISA-A score, with no significant complications. Our results support the use of FHL tendon transfer for patients with chronic tendo-Achilles rupture

Introduction and Aims: While successful long-term results have been shown for ligament reconstruction–tendon interposition arthroplasty for treatment of thumb basal joint osteoarthritis, the need for invasive ligament reconstruction has not been established. In this study we describe long-term results utilising the technique of tendon interposition arthroplasty with dynamic tendon transfer and capsulorrhaphy. Method: Twenty-four thumbs (21 patients) were evaluated at an average of 7.1 years (1.8–19.5 years) post-procedure. Capsulorrhaphy was performed utilising APL tendon slips where tissue was insufficient. The APB origin was advanced via tendon transfer (FCR to APB), providing a stabilising abductor moment. Subjective assessment was performed using Visual Analogue Scores (VAS), Disabilities of Arm, Shoulder, Hand (DASH) scores, and patient satisfaction scales. Objective assessment included post-operative range of motion (ROM), grip/pinch strength, and radiographs for interposition arthroplasty height. Results: Twenty of 21 patients (95%) were satisfied and described results as either good or excellent. Twenty of 21 patients (95%) would undergo surgery again. Mean VAS was 8.7 at rest and 10.2 with activity (0, no pain; 100, maximum pain). Mean DASH score was 16.9 (range from 0, no difficulty performing daily tasks to 100, unable to perform daily tasks). ROM, grip, lateral and tip pinch strengths were comparable with those of the contralateral thumb. AP radiographs showed preservation in 12 of 12 patients (100%). Fourteen of 21 patients received the procedure on their dominant hand. Conclusion: Treatment of basal joint osteoarthritis with our technique provided stable and functional reconstructions, resulting in excellent pain relief. Results were comparable to, or better than, those previously cited in the literature for alternative procedures. These results suggest that dogma requiring static ligament reconstruction or suspension may need to be re-evaluated

Introduction: Tibialis anterior tendon transfer (TATT) is a common procedure for recurrence in clubfeet treated with the Ponseti method. Fixation usually includes passing the tendon through a drill hole in the lateral cuneiform using sutures brought out through the plantar aspect of the foot. Drilling of the tunnel and passing the sutures holds potential for neurovascular damage. We performed a cadaver study to evaluate plantar nerve structures at risk during TATT. Method: TATT was performed to the lateral cuneiform in fresh frozen adult cadaver limbs. In 3 feet, the drill hole was made perpendicular to the surface of the lateral cuneiform (group A), in 3 feet, the drill hole was perpendicular to the weight bearing surface of the foot (group B), in 3 feet, the drill was directed at 15 degrees in the frontal and sagital planes (group C) and in another 3 feet the drill was aimed at the middle of the foot (group D). The tendon sutures were pulled through the plantar aspect using two Keith needles aimed in the same direction as the drill hole. A layered dissection was performed. The distance from the drill hole to the nearest nerve or nerve branch was measured. Keith needles were passed 20 times per foot. With each pass, damage to nerve structures was noted. Results: In group A, the drill was in proximity to the medial plantar nerve at a mean distance of 1.7mm (1–3mm). The bifurcation of the nerve trunk was found more proximally at a mean distance of 5mm (2–9mm). In group B, the drill was found to be close to the lateral plantar nerve branches at a mean distance of 0.3mm (0–1mm) with a mean distance to the bifurcation of 25.3mm (16–37mm). The drill hole in group C was at a mean distance of 1.7mm (0–3mm) to the lateral plantar nerve bifurcation and at a distance of 1mm to the lateral nerve branch in one case. In group D, the drill exited in the middle of the plantar aspect at a mean distance of 7.7mm (5–11mm) from the medial nerve branch and 13mm (10–18mm) from the bifurcation of the medial nerve and at a mean distance of 4.3mm (3–6mm) from the lateral nerve branch and 14.7mm (11–19mm) from the lateral nerve bifurcation. Passing the Keith needles resulted in hitting a nerve structure 12 times in group A, 20 times in group B, 6 times in group C and once in group D. Conclusion: In TATT, the drill hole should be aimed at the middle of the foot in the transverse and longitudinal planes. This results in a maximum distance to both the lateral and medial nerve. A blunt Keith needle might allow a safer passing of the sutures to avoid damage to nerves and vessels

The “Knot of Henry” was dissected in 16 embalmed cadaveric feet to reveal the complex interconnections between flexor hallucis longus (FHL) and flexor digi-torum longus (FDL) tendons. Three distinct anatomical patterns were observed. Tension was applied manually to FHL or FDL proximal to the Knot. Digit movement was different depending on the anatomical pattern. FHL or FDL tendon transfer is an accepted technique to prevent progression of acquired plano-valgus deformity. In order to minimise donor deficit, we suggest the use of either FHL or FDL should be based on assessment of the anatomical pattern at the time of surgery

We reviewed 19 patients (30 feet) with congenital vertical talus treated surgically between 1987 and 1999, 22 of them by the same surgeon. The etiological diagnosis was idiopathic in seven patients. Six patients had associated congenital abnormalities (four arthrogryposis, two digitotalar dysmorphism) and six had associated neurological abnormalities (three microcephalic, three spinal dysraphism). Only two patients had surgery after the age of 18 months. The mean age at surgery was 14.7 months (6 to 51). In 15 feet a two-stage procedure was performed. Lengthening of the extensor tendons, notably tibialis anterior, was followed six weeks later by posterior release. In 15 feet a one-stage procedure was done, with no lengthening of the extensors or transfer of tibialis anterior. The Kidner procedure was done in seven feet, but the tibialis posterior was never found to be subluxed and the procedure was abandoned. The calcaneocuboid joint was opened and pinned in eight feet. The peroneal tendons required lengthening in eight feet. At a mean follow-up of 5.8 years (2 to 13.5), results were excellent in 17 feet (normal forefoot and hind-foot). Results were good in seven feet (normal radiographs, normal hindfoot, but pronated forefoot). In four feet the result was fair (valgus hindfoot with a plantarflexion angle of the talus more than 35(). In one patient, the results in both feet were poor (uncorrected). All seven good results followed a two-stage procedure. We concluded that this was due to relative weakening of the lengthened tibialis anterior to the peroneus longus. Where necessary, plantarflexion of the talus should be corrected at operation, and this should be correlated with intra-operative fluoroscopy. Adequate reduction of the navicula inferomedially on the talar head obviates the need for tendon transfer

The equinovarus hind foot deformity is one of the most common deformities in children with spastic paralysis and is usually secondary to cerebral palsy. Split posterior tibialis tendon transfer is performed to balance the flexible spastic varus foot and is preferable to posterior tibialis lengthening, as the muscle does not loose its power and therefore the possibility of a valgus or calcaneovalgus deformity is diminished. The cohort of the study consisted of 50 children with cerebral palsy who underwent split posterior tibial lengthening to manage spastic equinovarus hind foot deformity. Our inclusion criteria were: ambulatory patients with cerebral palsy, age less than 6 years at the time of the operation, varus deformity of the hind foot during gait, flexible varus hind foot deformity, and the follow-up at least 4 years. We retrospectively evaluated 33 ambulant patients with flexible spastic varus hind foot deformity. Twenty-eight patients presented unilateral and 5 bilateral involvement. The mean age at the time of the operation was 10,8 years (6–17) and the mean follow-up was 10 years (4–14). Eighteen feet presented also equinus hind foot deformity, requiring concomitant Achilles cord lengthening. Clinical evaluation was based on the inspection of the patients while standing and walking, the range of motion of the foot and ankle, callus formation and the foot appearance using the clinical criteria of Kling et al. Anteroposterior and lateral weight-bearing radiographs of the talo-first metatarsal angle were measured. The position of the hind foot was evaluated according to the criteria of Chang et al for the surgical outcome. 20 feet were graded excellent, 14 were graded good and 4 were graded poor. Feet with recurrent equinovarus deformity or overcorrection into valgus or calcaneovalgus deformity were considered as poor results. There were 23 feet presenting concomitant cavus foot component that underwent supplementary operations performed at the same time with the index operation. None of the feet presented mild or severe valgus postoperatively, while 4 feet presented severe varus deformity and underwent calcaneocuboid fusion sixteen and eighteen months after the index operation. On the anteroposterior and lateral weight-bearing radiographs the feet with severe varus had a negative talo-first metatarsal angle (mean −26,8 ± 18,4), those with mild varus had a mean of −14,5 ± 12,2. In feet with the hind foot in neutral position the mean value was 5.0 ± 7.4. The results of the feet in patients with hemiplegic pattern were better and significantly different than the diplegic and quadriplegic ones (p = 0.005). The results in our cases were in general satisfactory as 34 out of 38 feet were graded excellent and good. The feet with poor results presented a residual varus deformity due to intraoperative technical errors

Aims

To describe and analyze the mid-term functional outcomes of a large series of patients who underwent the Hoffer procedure for brachial plexus birth palsy (BPBP).

Flat foot due to rupture of the tibialis posterior tendon has not previously been described in children. We present three young patients who developed unilateral pes planus after old undiagnosed lacerations of the tendon. Transfer of the flexor hallucis longus to the distal stump of the tibialis posterior tendon achieved good results in all three cases

The December 2023 Children’s orthopaedics Roundup. 360. looks at: A comprehensive nonoperative treatment protocol for developmental dysplasia of the hip in infants; How common are refractures in childhood?; Femoral nailing for paediatric femoral shaft fracture in children aged eight to ten years; Who benefits from allowing the physis to grow in slipped capital femoral epiphysis?; Paediatric patients with an extremity bone tumour: a secondary analysis of the PARITY trial data; Split tibial tendon transfers in cerebral palsy equinovarus foot deformities; Liposomal bupivacaine nerve block: an answer to opioid use?; Correction with distal femoral transphyseal screws in hemiepiphysiodesis for coronal-plane knee deformity

Aims. Multiple secondary surgical procedures of the shoulder, such as soft-tissue releases, tendon transfers, and osteotomies, are described in brachial plexus birth palsy (BPBP) patients. The long-term functional outcomes of these procedures described in the literature are inconclusive. We aimed to analyze the literature looking for a consensus on treatment options. Methods. A systematic literature search in healthcare databases (PubMed, Embase, the Cochrane library, CINAHL, and Web of Science) was performed from January 2000 to July 2020, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines. The quality of the included studies was assessed with the Cochrane ROBINS-I risk of bias tool. Relevant trials studying BPBP with at least five years of follow-up and describing functional outcome were included. Results. Of 5,941 studies, 19 were included after full-text screening. A total of 15 surgical techniques were described. All studies described an improvement in active external rotation (range 12° to 128°). A decrease in range of motion and Mallet score after long-term (five to 30 years) follow-up compared to short-term follow-up was seen in most studies. Conclusion. The literature reveals that functional outcome increases after different secondary procedures, even in the long term. Due to the poor methodological quality of the included studies and the variations in indication for surgery and surgical techniques described, a consensus on the long-term functional outcome after secondary surgical procedures in BPBP patients cannot be made.

Introduction:. Reverse total shoulder arthroplasty (RTSA) has become an accepted surgical treatment for patients with severe deficiency of the rotator cuff. Despite the utility of RTSA in managing difficult shoulder problems, humeral rotation does not reliably improve and may even worsen following RTSA. Several approaches to increase active external rotation (aER) postoperatively have been proposed including the use of concomitant latissimus dorsi tendon transfer (LDTT) or the use of an increased lateral-offset glenosphere (LG). We hypothesized that clinical outcome and range of motion after RTSA with a +4 mm or +6 mm LG would be comparable to RTSA with LDTT in patients with a lack of aER preoperatively. Methods:. An IRB-approved, prospective, single surgeon RTSA registry was reviewed for patients treated with LDTT or LG for preoperative aER deficiency with minimum 1-year follow-up. Patients qualified for aER deficiency if they had a positive ER lag sign or less than or equal to 10 degrees of aER preoperatively. Matched control groups with patients that did not have preoperative lack of aER and were not treated with LDTT or LG were included for comparison. Outcomes measures included Constant-Murley score (CMS), American Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Value (SSV), ASES Activities of Daily Living (ADL) score, Visual Analogue pain Scale (VAS), active forward elevation (aFE), active internal rotation (aIR), and aER. An independent, institutional biostatistician performed statistical analyses. Results:. The LDTT group had 21 patients (10 male, 11 female) and the LG group had 16 patients (5 male, 11 female). CMS, ASES, SSV, ADL, VAS, and aFE were significantly improved in case and control groups following RTSA (P < .05). There was no significant difference in the degree of improvement of CMS, ASES, SSV, ADL, VAS or aFE between the LDTT group and its control group or the LG group and its control group (P > .05). aER was significantly improved in the LDTT and LG groups (P < .001), but did not improve significantly in either control group (P > .05) (Figure 1). The LDTT group had a significantly lower postoperative aER than its control group (P = .001), whereas the LG group had similar postoperative aER to its control group (P = .376) (Figure 1). The LG group had significantly greater aER preoperatively and postoperatively than the LDTT group (P < .001 and P = .013). There was no significant difference in degree of improvement of aER between the LDTT and LG groups (P = .212). The LDTT group had a significantly lower postoperative aIR than its control group (P=.025), whereas the LG group had similar postoperative aIR to its control group (P = .234). The LG group had significantly greater improvement in aIR than the LDTT group (P=.009). Conclusion:. To our knowledge, this is the first series to compare outcomes of two common techniques used to improve aER following RTSA. In this series, we found overall similar improvements in outcomes between the groups. These results suggest that use of a LG may be preferable to LDTT given the relatively simplified surgical technique, similar improvement in aER, comparable clinical outcome scores, and the added benefit of improved aIR

Inability to actively supinate the forearm makes common activities of daily living and certain vocational activities awkward or impossible to perform. A total of 11 patients with deficient supination of the arm underwent transfer of the tendon of flexor carpi ulnaris to the split tendon of brachioradialis with its bony insertion into the radial styloid left intact. Active supination beyond neutral rotation was a mean of 37.2° (25° to 49.5°) at a minimum follow-up of three years, representing a significant improvement (95% confidence interval 25 to 50, p < 0.001). Functional evaluation of the hand after this transfer showed excellent and good results in ten patients and fair in one.

The split tendon of brachioradialis as an insertion for transfer of the flexor carpi ulnaris appears to provide adequate supination of the forearm without altering the available pronation and avoids the domination of wrist extension sometimes associated with transfers of the flexor carpi ulnaris to the radial extensors of the wrist.

Among the most popular techniques for the management of radial nerve palsy is the transfer of the Pronator Teres (PT) to the Extensor Carpi Radialis Brevis (ECRB), of the Flexor Carpi Radialis (FCR) to the Extensor Digitorum Communis (EDC) and of the Palmaris Longus (PL) to rerouted Extensor Pollicis Longus (EPL). This retrospective study was undertaken to assess the outcome of flexor carpi radialis transfer in the treatment of radial nerve palsy.

Twenty patients with a mean age of 36 years were included in this study. Surgical management, as described above, was decided since all patients had irreparable damage to the nerve. Parameters that were assessed included range of wrist motion, dynamic power of wrist flexion and extension, and radial and ulnar deviation and function.

The average follow-up was 4.5 years. Compared to a control group of 10 volunteers of similar characteristics, all patients achieved a functional range of motion and satisfactory power of wrist motion. All patients returned to their previous occupation.

Transfer of Flexor Carpi Radialis tendon for irreparable radial nerve palsy yields satisfactory results. Therefore, it can be expected that patients will obtain a functional range of motion as well as an adequate strength of motion.

Residual club foot (CTEV) is a challenging deformity which may require transfer of the tibialis anterior tendon to a more lateral position. The senior author has developed a modified SPLATT for residual forefoot supination in CTEV.

We describe the SPLATT procedure and evaluate clinical and radiological outcomes of 11 patients(14 feet) (mean follow up 6.6 years; range 5.5–8.9) (mean age 6.9 years; range 2.9–10.0). Two patients had cerebral palsy, 1 spina bifida and 1 juvenile rheumatoid arthritis, the remaining 7 patients were ideopathic.

Outcome measures based on patient centred assessment of function and foot appearance, by using the patient applied assessments of Chesney, Utukuri and Laaveg & Ponsetti (there is increasing recognition that doctor-centred or radiograph-based scoring systems do not tally well with patient satisfaction).

Objective assessment of outcome was provided by measurement of certain radiological parameters on the immediate pre-operative and the follow up weight-bearing radiographs (1st ray angle, talar-1st metatarsal angle, talar-2nd metatarsal angle, talo-calcaneal angle). The calcaneal line passing through the medial 1/3 of the cuboid or medial to the fourth metatarsal was also noted. The Blecks grade was recorded (pre-op 100% moderate-severe; post-op 88% mild-moderate). Parents assessed outcome based upon ‘best level of activity’, functional limitation and willingness to recommend treatment to others.

Mean Chesney score at the time of follow up was 12.3 (8 to 15); mean Utukuri score was 15.8 (10 to 24); Laaveg and Ponsetti score was 81.5 (67 to 95). The best activity level achievable was ‘unlimited’ in 4 patients, ‘football’ in 4 patients, ‘running’ in 1 and limited by an associated condition in 2 patients (1 juvenile rheumatoid arthritis; 1 cerebral palsy related spastic paraparesis). All patients/parents indicated that they would undergo the same procedure again. One patient had delayed wound healing treated successfully with dressings.

The 1st ray angle pre-operatively was 61.2°(range 50–70°), post-operatively it was 62.1°(range 50–81°). The talar-1st metatarsal angle was 28.8°(range 15–44°) pre-operatively and 19.1°(range 4–34°) post-operatively. The pre and post–operative talar-2nd metatarsal angles were 22.5°(range 0–35°) and 12.3(range 0–29°) respectively, the talo-calcaneal angle was 17.5°(range 10–35°) and 13.7(range 5–20°) respectively. The pre and postoperative lateral talo-calcaneal angles were 34.5°(range 25–40°) and 30.6(range 13–45°).

The recognition that patient orientated subjective assessment is gaining in acceptance, and confirm patient satisfaction with function, cosmesis and pain levels with the SPLATT procedure. More traditional radiological outcome measures also confirm that the modified SPLATT is a safe, effective and acceptable procedure.

Purpose of the study

To determine the outcome after the Semi-tendinosis tendon was used in reconstruction of the Medial Patella-femoral ligament using a fixed dynamic stabilising structure.

An inability to extend the hallux following trauma is most often observed after direct laceration to the Extensor Hallucis Longus [EHL]. Primary repair, subsequent splinting and appropriate rehabilitation best deal with this type of injury. Damage to either the EHL muscle belly or the motor nerve to EHL are uncommon causes of the dropped hallux and present difficult reconstructive problems. Damage to the motor nerve branch to EHL in isolation is an uncommon problem and as far as we are aware surgery to address this pathology has not previously been described in the literature. This problem can occur after a penetrating injury, high tibial osteotomy or intramedullary nailing of a fractured tibia. We describe the operative procedure, technique and outcome in two cases of extensor hallucis longus to extensor digitorum communis (EDC) transfer to overcome this problem. A longitudinal skin incision is made just lateral to the tibia in the distal anterior part of the leg. The extensor retinaculum is divided and the EHL tendon identified and divided just distal to the EHL musculotendinous junction. The extensor digitorum communis (EDC) is then identified and the proximal stump of EHL woven into the EDC. A Pulvertaft weave technique is used and secured with 3/0 Ethibond suture. The appropriate amount of tension is placed on the repair by simulating weight bearing on the foot, ensuring the great toe remains in the neutral position. The extensor retinaculum is then repaired with 2/0 Vicryl and the skin closed with interrupted nylon sutures. The wound is infiltrated with 0.5% Marcaine to aid postoperative pain relief. A protected active motion rehabilitation program follows the surgery. We have used this technique in two cases, both have regained active extension of the hallux.

Abstract

Specific brace-fitting complications in idiopathic congenital talipes equinovarus (CTEV) have been rarely described in published series, and usually focus on non-compliance. Our primary aim was to compare the rate of persistent pressure sores in patients fitted with Markell boots and Mitchell boots. Our additional aims were to describe the frequency of other brace fitting complications and identify age trends in these complications. A retrospective analysis of medical files of 247 idiopathic CTEV patients born between 01/01/2010 - 01/01/2021 was performed. Data was collected using a REDCap database. Pressure sores of sufficient severity for clinician to recommend time out of brace occurred in 22.9% of Mitchell boot and 12.6% of Markell boot patients (X. 2. =6.9, p=0.009). The overall rate of bracing complications was 51.4%. 33.2% of parents admitted to bracing non-compliance and 31.2% of patients required re-casting during the bracing period for relapse. For patients with a minimum follow-up of age 6 years, 44.2% required tibialis anterior tendon transfer. Parents admitting to non-compliance were significantly more likely to have a child who required tibialis anterior tendon transfer (X. 2. =5.71, p=0.017). Overall rate of capsular release (posteromedial release or posterior release) was 2.0%. Neither medium nor longterm results of Ponseti treatment in the Australian and New Zealand clubfoot have been published. Globally, few publications describe specific bracing complications in clubfoot, despite this being a notable challenge for clinicians and families. Recurrent pressure sores is a persistent complication with the Mitchell boots for patients in our center. In our population of Australian clubfoot patients, tibialis anterior tendon transfer for relapse is common, consistent with the upper limit of tibialis anterior tendon transfer rates reported globally

Background. Iatrogenic hallux varus is a rare complication after hallux valgus surgery. Operative treatment comprises a wide variety of techniques, of which the reversed transfer of the abductor hallucis tendon is the most recent described technique. Methods. This paper will present the long-term clinical results of the reversed transfer of the abductor hallucis longus. Therefore, we performed a prospective clinical observational study on 16 female patients. Our hypothesis is that the tendon transfer will persist in a good alignment and patient satisfaction on long term. There is a 100% follow-up rate with a range from 10 to 101 months. Patients were subjected to a clinical examination, three questionnaires and their general satisfaction. Results. Out of 16 patients, at time of follow-up, we found a positive correlation between the subjective outcome score and alignment (r = 0.59), and between the general satisfaction and alignment (r = 0.77). Based on the general satisfaction we achieved a success satisfaction rate of 69% (11 patients). The other 31% (5 patients) patient group was only satisfied with major reservations or not satisfied at all. The two most invalidating complications were a coronal or sagittal malalignment or the combination of both. Conclusion. Our results suggest that the reverse abductor hallucis tendon transfer is a good technique to treat a supple iatrogenic hallux varus with an observed success satisfaction rate of 69% at a mean follow-up time of 48 (range 10–101) months. However, patients should be informed that on the long-term loss of correction is possible

Rotator cuff tears are the most common cause of shoulder disability, affecting 10% of the population under 60 and 40% of those aged 70 and above. Massive irreparable rotator cuff tears account for 30% of all tears and their management continues to be an orthopaedic challenge. Traditional surgical techniques, that is, tendon transfers are performed to restore shoulder motion, however, they result in varying outcomes of stability and complications. Superior capsular reconstruction (SCR) is a novel technique that has shown promise in restoring shoulder function, albeit in limited studies. To date, there has been no biomechanical comparison between these techniques. This study aims to compare three surgical techniques (SCR, latissimus dorsi tendon transfer and lower trapezius tendon transfer) for irreparable rotator cuff tears with respect to intact cuff control using a clinically relevant biomechanical outcome of rotational motion. Eight fresh-frozen shoulder specimens with intact rotator cuffs were tested. After dissection of subcutaneous tissue and muscles, each specimen was mounted on a custom shoulder testing apparatus and physiologic loads were applied using a pulley setup. Under 2.2 Nm torque loading maximum internal and external rotation was measured at 0 and 60 degrees of glenohumeral abduction. Repeat testing was conducted after the creation of the cuff tear and subsequent to the three repair techniques. Repeated measures analysis with paired t-test comparisons using Sidak correction was performed to compare the rotational range of motion following each repair technique with respect to each specimen's intact control. P-values of 0.05 were considered significant. At 0° abduction, internal rotation increased after the tear (intact: 39.6 ± 13.6° vs. tear: 80.5 ± 47.7°, p=0.019). Internal rotation was higher following SCR (52.7 ± 12.9°, intact - SCR 95% CI: −25.28°,-0.95°, p=0.034), trapezius transfer (74.2 ± 25.3°, intact – trapezius transfer: 95% CI: −71.1°, 1.81°, p=0.064), and latissimus transfer (83.5 ± 52.1°, intact – latissimus transfer: 95% CI: −118.3°, 30.5°, p=0.400) than in intact controls. However, internal rotation post SCR yielded the narrowest estimate range close to intact controls. At 60° abduction, internal rotation increased after the tear (intact: 38.7 ± 14.4° vs. tear: 49.5 ± 13°, p=0.005). Internal rotation post SCR did not differ significantly from intact controls (SCR: 49.3 ± 10.1°, intact – SCR: 95% CI: −28°, 6.91°, p=0.38). Trapezius transfer showed a trend toward significantly higher internal rotation (65.7 ± 21.1°, intact – trapezius transfer: 95% CI: −55.7°, 1.7°, p=0.067), while latissimus transfer yielded widely variable rotation angle (65.7 ± 38°, intact – latissimus transfer: 95% CI: −85.9°, 31.9°, p=0.68). There were no significant differences in external rotation for any technique at 0° or 60° abduction. Preliminary evaluation in this cadaveric biomechanical study provides positive evidence in support of use of SCR as a less morbid surgical option than tendon transfers. The cadaveric nature of this study limits the understanding of the motion to post-operative timepoint and the results herein are relevant for otherwise normal shoulders only. Further clinical evaluation is warranted to understand the long-term outcomes related to shoulder function and stability post SCR

Purpose of study. Internal rotation (IR) contracture of the shoulder is a frequent complication of obstetric brachial plexus injury, even in the face of full neurological recovery. Surgical procedures to treat this complication include tendon transfers, capsular release and osteotomies. We compared the outcomes in patients who had arthroscopic release only and those who also underwent a tendon transfer. Methods. We retrospectively reviewed the clinical records of all patients with OBPI presenting to our unit in the years 2002–2012 who underwent surgical procedures for the treatment of an IR contracture of the shoulder. Increase in range of external rotation (ER) in adduction and abduction intra-operatively was recorded. At follow-up, active ER, the Mallet score, presence of an ER contracture and the “drop-arm” sign was recorded. Results. 25 procedures were performed in 22 patients. Mean intra-operative gain in ER was greatest in those patients who had simultaneous arthroscopic release and a tendon transfer (83.3° and 60.5° in adduction and abduction respectively). This group had the greatest average range of active ER at follow up (47.5°), the lowest incidence of a “drop-arm” sign (14%), but also the highest incidence of ER contracture (75%). Patients who underwent arthroscopic anterior shoulder release only, had the highest average Mallet score at final follow up (17.1 compared to 16.3 in the scope and tendon transfer group), 45% incidence of a “drop-arm” sign and also the lowest incidence of ER contracture (32%). General satisfaction was greatest in the scope plus tendon transfer group. Conclusion. Patients who had arthroscopic release and tendon transfer had better ER range and power but more severe ER contractures than patients who underwent arthroscopic release only. Patient satisfaction and Mallet scores were comparable between the two groups and therefore bring into question the need for early tendon transfer in these patients. NO DISCLOSURES

Introduction. It has been postulated that a mild clubfoot does better than a severe clubfoot no matter what treatment course is taken. There have been previous efforts to classify clubfoot. For units worldwide that use the Ponseti Method of clubfoot management, the Pirani scoring system is widely used. This scoring system has previously been shown to predict the number of plasters required to gain correction. Our study aimed to investigate whether the Pirani score gave an indication of longer-term outcome using tibialis anterior tendon transfer as an endpoint. Methods. A prospectively collated database was used to identify all patients treated in the Ponseti clinic at the Royal Manchester Children's Hospital between 2002 and 2005 with idiopathic clubfoot who had not received any treatment prior to their referral. Rate of tibialis tendon transfer as well as the patient's presenting Pirani score were noted. Feet were grouped for analytical purposes into a mild clubfoot (Pirani score <4) and a severe clubfoot (Pirani score 4) category depending on initial examination. Clinic records were reviewed retrospectively to identify patients who were poorly compliant at wearing boots and bars and were categorised into having “good” or “bad” compliance with orthosis use. Results. 132 feet in 94 children were included in the study. 30 (23%) tibialis tendon transfers were performed at a mean of 4.2 years (range 2.3–5.5 years). Children with severe clubfoot had a significantly higher rate of tendon transfer compared with those with mild clubfoot (28% vs. 6%; p=0.0001). 81% of patients were classified as being “good” boot wearers. Tibialis tendon transfer rates in those who were poorly compliant with boot usage were significantly higher compared with those with good compliance (52% vs. 16%; p=0.0003). There was a significantly higher tendon transfer rate in those with severe disease and poor compliance compared with good compliance (69% vs. 20%; p=0.0002). There was no association between boot compliance and tendon transfer rates in those with mild disease. Conclusion. This study shows that late recurrences, requiring tibialis anterior tendon transfer, are associated with severity of disease at presentation and compliance with use of orthoses. Tendon transfer rates are higher for those with severe disease. We have confirmed previous reports that compliance with orthotic use is associated with recurrence. However, the novel findings regarding recurrence rates in mild clubfeet may have implications regarding usage of orthoses in the management of mild idiopathic clubfeet after initial manipulation using the Ponseti method

Deficiency in the gluteus medius and minimus abductor muscles is a well-recognised cause of hip pain and considerable disability. These patients present a management challenge, with no established consensus for surgical intervention. Whiteside in 2012 described a surgical technique for gluteus maximus tendon transfer, with successful outcomes reported. This study is the largest known case series to date of patients undergoing gluteus maximus tendon transfer with clinical and patient reported outcomes measured. 13 consecutive patients were included in the study. All patients had clinical evidence of abductor dysfunction together with MRI evidence of gluteal atrophy and fat infiltration. All patients underwent gluteus maximus transfer with surgery performed according to the procedure described by Whiteside. Patients were followed up with both clinical assessment and patient questionnaires conducted. Mean age was 69 (range 54–82) with 9 patients (69%) having previous Hardinge approach to the affected hip. 6 patients (46%) reported they were satisfied overall with the procedure and 5 patients (38%) were unsatisfied. 7 patients (54%) had improvements in visual analogue scale of pain and 5 patients (54%) reported overall improvements in function. Mean Oxford Hip Score on follow up was 20/48 (range 5–48) and trendelenberg test was positive in 11 patients (85%). No differentiating variable could be identified between patients with positive and negative outcomes (Assessed Variables: Age, sex, BMI, aetiology and gluteus maximus muscle thickness). Clinical outcomes were varied following gluteus maximus tendon transfer for chronic hip abductor dysfunction. Results are considerably less promising than pre-existing studies would suggest

Massive posterosuperior cuff tears (mRCT) retracted to the glenoid are surgically challenging and often associated with high retear rates. Primary repair is a less-favourable option and other salvage procedures such as SCR and tendon transfers are used. This study presents clinical and radiological outcomes of muscle advancement technique for repair of mRCT. Sixty-one patients (mean age 57±6, 77% males and 23% females) (66 shoulders) underwent all-arthroscopic rotator cuff repair that included supraspinatus and infraspinatus subperiosteal dissection off scapular bony fossae, lateral advancement of tendon laminae, and tension-free double-layer Lasso Loop repair to footprint. Pre-and post-operative range of motion (ROM), cuff strength, VAS, Constant, ASES, and UCLA scores were assessed. Radiologic assessment included modified Patte and Goutallier classifications. All patients had MRI at 6 months to evaluate healing and integrity of repair was assessed using Sugaya classification with Sugaya 4 and 5 considered retears. Advanced fatty degeneration (Goutallier 3-4) was present in 44% and 20% of supraspinatus and infraspinatus. Tendon retraction was to the level of or medial to glenoid in 22%, and just lateral in 66%. 50.8% mRCT extended to teres minor. Subscapularis was partially torn (Lafosse 1-3) in 46% and completely torn (Lafosse 4-5) in 20%. At mean follow-up (52.4 weeks), a significant increase in ROM, Relative Cuff Strength (from 57% to 90% compared to contralateral side), VAS (from 4 ±2.5 to 1±1.7), Constant (50±17.8 to 74 ±13.0), ASES (52 ±17.5 to 87 ±14.9), and UCLA (16± 4.9 to 30 ±4.9) scores were noted. There were six retears (10%), one failure due to P. acnes infection. 93% returned to pre-injury work and 89% of cases returned to pre-injury sport. Satisfaction rate was 96%. Muscle advancement technique for mRCT is a viable option with low retear rates, restoration of ROM, strength, and excellent functional outcomes

Complications such as implant loosening, infection, periprosthetic fracture or instability may lead to revision arthroplasty procedures. There is limited literature comparing single-stage and two-stage revision shoulder arthroplasty. This study aims to compare clinical outcomes and cost benefit between single-stage and two-stage revision procedures. Thirty-one revision procedures (mean age 72+/-7, 15 males and 16 females) performed between 2016 and 2021 were included (27 revision RSA, 2 revision TSA, 2 failed ORIFs). Two-stage procedures were carried out 4-6 weeks apart. Single-stage procedures included debridement, implant removal and washout, followed by re-prep, re-drape and reconstruction with new instrumentations. Clinical parameters including length of stay, VAS, patient satisfaction was recorded preoperatively and at mean 12-months follow up. Cost benefit analysis were performed. Seven revisions were two-stage procedures and 24 were single-stage procedures. There were 5 infections in the two-stage group vs 14 in the single-stage group. We noted two cases of unstable RSA and 8 other causes for single-stage revision. Majority of the revisions were complex procedures requiring significant glenoid and/or humeral allografts and tendon transfers to compensate for soft tissue loss. No custom implants were used in our series. Hospital stay was reduced from 41+/-29 days for 2-stage procedures to 16+/-13 days for single-stage (p<0.05). VAS improved from 9+/-1 to 2+/-4 for two-stage procedures and from 5+/-3 to 1+/-2 for single-stages. The average total cost of hospital and patient was reduced by two-thirds. Patient satisfaction in the single-stage group was 43% which was comparable to the two-stage group. All infections were successfully treated with no recurrence of infection in our cohort of 31 patients. There was no instability postoperatively. 3 patients had postoperative neural symptoms which resolved within 6 months. Single-stage procedures for revision shoulder arthroplasty significantly decrease hospital stay, improve patients’ satisfaction, and reduced surgical costs

Tendinopathy can commonly occur around the foot and ankle resulting in isolated rupture, debilitating pain and degenerative foot deformity. The pathophysiology and key cells involved are not fully understood. This is partly because the dense collagen matrix that surrounds relatively few resident cells limits the ability of previous techniques to identify and target those cells of interest. In this study, we apply novel single cell RNA sequencing (CITE-Seq) techniques to healthy and tendinopathic foot/ankle tendons. For the first time we have identified multiple sub-populations of cells in human tendons. These findings challenge the view that there is a single principal tendon cell type and open new avenues for further study. Healthy tendon samples were obtained from patients undergoing tendon transfer procedures; including tibialis posterior and FHL. Diseased tendon samples were obtained during debridement of intractable Achilles and peroneal tendinopathy, and during fusion of degenerative joints. Single cell RNA sequencing with surface proteomic analysis identified 10 sub-populations of human tendon derived cells. These included groups expressing genes associated with fibro-adipogenic progenitors (FAPs) as well as ITGA7+VCAM1- recently described in mouse muscle but, as yet, not human tendon. In addition we have identified previously unrecognised sub-classes of collagen type 1 associated tendon cells. Each sub-class expresses a different set of extra-cellular matrix genes suggesting they each play a unique role in maintaining the structural integrity of normal tendon. Diseased tendon harboured a greater proportion of macrophages and cytotoxic lymphocytes than healthy tendon. This inflammatory response is potentially driven by resident tendon fibroblasts which show increased expression of pro-inflammatory cytokines. Finally, identification of a previously unknown sub-population of cells found predominantly in tendinopathic tissue offers new insight into the underlying pathophysiology. Further work aims to identify novel proteins targets for possible therapeutic pathways

The foot and ankle are very commonly affected in various paralytic conditions. Paralysis of different muscles acting on the foot results in characteristic gait aberrations. The gait abnormalities are a result of one or more of the consequences of paralysis including: loss of function, muscle imbalance, deformity and instability of joints. The aims of treatment of the paralysed foot and ankle are to: make the foot plantigrade, restore active dorsiflexion during the swing phase of gait (if this is not possible then prevent the foot from ‘dropping’ into plantar flexion during swing), ensure that the ankle and subtalar joints are stable throughout the stance phase of gait, facilitate a powerful push-off at the terminal part of the stance phase (if this is not possible, at least prevent a calcaneal hitch in terminal stance). The specific aims of treatment in each patient depend on the pattern and the severity of paralysis that is present and hence the aims are likely to vary. In order to determine what treatment options are available in a particular patient, it is imperative that a careful clinical assessment of the foot is done. Based on the clinical assessment, these questions need to be answered before planning treatment: What are the muscles that are paralysed What is the power of each muscle that is functioning? Is there muscle imbalance at the ankle, subtalar or midtarsal joints that has either already produced a deformity or has the potential to produce a deformity in future? Are there any muscles of grade V power that can be spared for a tendon transfer without producing a fresh imbalance or instability. To facilitate responses to these questions, the muscle power of each muscle can be charted on a template that facilitates graphic representation of the muscle balance around the axes of the ankle and subtalar joints. This assessment clarifies whether a tendon transfer is a feasible option. If a tendon transfer is considered feasible, then the following questions also need to be answered: Is there a fixed, static deformity that needs to be corrected prior to a tendon transfer? If a tendon transfer was performed, would the child be capable of comprehending and cooperating with the post-operative muscle re-education programme?. The decision-making process will be outlined and the use of the template in choosing the tendon transfer and deciding the site of anchorage of the transferred tendon will be explained. With suitable examples the choice of tendon transfers in different patterns of paralysis would be illustrated

Abstract. Introduction. Derby technique for posterolateral corner (PLC) reconstruction uses a doubled gracilis autograft to reconstruct the popliteo-fibular ligament (PFL) and a split biceps tendon transfer to reconstruct the lateral collateral ligament (LCL). We report midterm outcomes of a case series who underwent PLC reconstruction. Methodology. A retrospective review of 27 patients who underwent PLC reconstruction from 2012 until 2018 was performed (6 females, 21 males, median age 26). Median time interval from injury to primary procedure was 10 months. Outcomes were recorded as per clinical assessment and outcome scores. Results. All patients had no varus laxity in full knee extension. Similarly, at 30° of knee flexion, 25 patients (92.5%) had no varus laxity and 2 patients (7.5%) had grade 1 laxity. No patients demonstrated abnormal external rotation at final follow up. Outcome scores were obtained from 17 patients who underwent primary ligament reconstruction at a mean follow up of 72 months postoperatively. The mean Lysholm score was 94 +/-5.5 (72–100) and mean subjective IKDC score was 78/87 (89.6%) (51–87). 90% of our patients had gained normal or nearly normal IKDC scores on returning to routine activities of daily living and sports following surgery compared to their pre-injury status. Conclusion. Our technique enables an anatomical LCL & PFL reconstruction in isolation or in combination with ACL/PCL reconstruction or to augment an acute repair without contralateral graft harvest or allograft. The functional knee scores demonstrated in this cohort are comparable and in fact superior to previously published knee scores after PLC reconstruction

This pilot study reports the clinical outcomes of a combination of partial subscapularis tendon transfer and small-head hemiarthroplasty in patients with rotatator cuff arthropathy. A total of 30 patients (30 shoulders; eight men and 22 women) with a mean age of 74 years (55 to 84) were assessed at a mean follow-up of 31 months (24 to 60). The inclusion criteria were painful cuff tear arthropathy with normal deltoid function and a non-degenerative subscapularis muscle and tendon and a preserved teres minor. Outcome was assessed using the University of California Los Angeles score, the Japanese Orthopaedic Association score, and the Oxford Shoulder Score. Radiographic measurements included the centre of rotation distance and the length of the deltoid. All clinical scores were significantly improved post-operatively. The active flexion and external rotation improved significantly at the most recent follow-up (p < 0.035). Although the mean centre of rotation distance changed significantly (p < 0.001), the mean length of the deltoid did not change significantly from the pre-operative value (p = 0.29). The change in the length of the deltoid with < 100° flexion was significantly less than that with > 100° (p < 0.001). Progressive erosion of the glenoid was seen in four patients. No patient required revision or further surgery. A combination of partial subscapularis tendon transfer and small-head hemiarthroplasty effectively restored function and relieved pain in patients with rotator cuff arthropathy.

Introduction. Flexor Hallucis Longus (FHL) tendon transfer is a well-recognised salvage operation for irreparable tendon Achilles (TA) ruptures and intractable Achilles tenonopathy. Several case series describes the technique and results of arthroscopic FHL tendon transfers. We present a comparative case series of open and arthroscopic FHL tendon transfers from Southmead Hospital, Bristol, UK. Methods. For the arthroscopic FHL transfers in most cases the patients were positioned semi prone with a tourniquet. A 2 or 3 posterior portal technique was used and the tendon was secured using an RCI screw. The rehabilitation was similar in both groups with 2 weeks in an equinus backslab followed by gradual dorsiflexion in a boot over the following 6 weeks. Anticoagulation with oral aspirin for 6 weeks was used. A retrospective case note review was performed. Results. There were 12 arthroscopic (8 males, 4 female) and 16 open procedures (9 male, 7 female). Both had a mean age of 56. 1 arthroscopic FHL was lost to follow up. There were no concomitant procedures in the arthroscopic group. In the open group the TA was repaired in 7 cases (3 of these involved z-shortening). There was 1 plantaris interposition, 1 V-Y advancement and 1 gastrocnemius advancement. Degenerate tendon was excised in 1 severe re-rupture of a calcified tendinopathic achilles. There was no difference in tourniquet time between the groups (arthroscopic 69mins vs open 64 mins, p=0.64). There were no complications in the arthroscopic group. In the open group there was 1 superficial wound infection, 1 nerve injury & 1 delayed DVT at 3 months. Conclusion. Arthroscopic FHL transfer is a safe and effective surgical option when no other achilles procedures are required. The soft tissue insult is minimal, making it a good option for patients with poor soft tissues or neurovascular compromise

Introduction The role of tendon transfer in progressive hereditary motor sensory neuropathy (CMT) is controversial. This paper examines a large single surgeon cohort and reviews the surgical outcome of tendon transfers against a large group of CMT patients represented by the Australian CMT Health Survey 2001. Methods A retrospective review was carried out in 29 patients (57 feet) with CMT, managed surgically by a single author (GW). Functional outcomes were measured using standard tools such as SF-36, AOFAS ankle hindfoot clinical rating scale, and a clinical review including a specially designed questionairre. Quality of life and functional outcome has been compared with the Australian CMT Health Survey 2001 in 324 patients. Twenty-nine patients were managed with tendon transfers, typically by flexor to extensor transfer of toes, combined with peroneus longus release and transfer, and tibialis posterior transfer. Results The Levitt classification rated 80% of patients as having good-excellent outcomes. Ninety-two percent of patients reported an improvement overall with surgery, specifically 52% reported improvement in pain, 85% felt their gait had benefited, and 74% reported an improvement in the appearance of their foot deformity, as a direct result of their surgery. All patients reviewed would recommend similar surgery to others, and 92% of those surveyed wished they had their surgery much earlier (months to years). The AOFAS clinical rating system for ankle-hindfoot showed an average improvement of 36 points out of 100. In general, patients treated by this method were improved when considered against a larger cohort both in quality of life measures and functional outcome. This combination was not always successful, and a small number of disappointed patients were identified. Conclusions Tendon transfers in the younger patient has a role in the treatment of flexible deformities in CMT, and improving quality of life. This paper shows that patients benefit at an earlier stage of their disease by tendon transfers. Indications for tendon transfers have been refined by this study and lessons learned recognised

Abstract. Background. Traumatic knee dislocations are devastating injuries and there is no single best accepted treatment. Treatment needs to be customised to the patient taking into consideration injury to the knee; associated neurovascular and systemic injuries. Objective. This study looked at functional outcome of a single surgeon case series of patients who underwent surgical management of their knee dislocation. Methods. Seventy patients with knee dislocation were treated with multi-ligament reconstruction at a major trauma centre. Acute surgical repair and reconstruction with fracture fixation within 3 weeks was preferred unless the patient was too unstable (Injury severity score>16). PCL was primarily braced and reconstructed subsequently, if required. Outcome was collected prospectively using IKDC score, KOOS and Tegner score. Results. The mean age of the patients was 35yrs (17–74), 53 males and 17 females. 5 patients had CPN injury (7%), 3 had vascular injury (4.2%), 2 had combined CPN and vascular injury (2.8%). Acute surgical treatment was done in 48 patients while 10 had staged reconstruction. 22 patients had delayed reconstruction. The mean follow-up period was 4.8 years (1–12 yrs). According to the IKDC score 67% of the patients had near-normal knee function. The mean Tegner activity scale postoperatively was 4.5 (preinjury 6.5) and the mean KOOS score was 75.3. Four patients had stiffness and needed arthroscopic arthrolysis, two patients had a residual foot drop from the original injury and needed tendon transfer. Conclusion. Traumatic knee dislocation is a challenging problem but good outcomes can be achieved by surgical management

Abstract. Objectives. Achilles tendon ruptures are common in the UK, with data demonstrating a significant rise in incidence over the past years. Chronic Achilles ruptures have been less well defined in literature, and repair techniques vary significantly. A surge in publications reporting various management options for chronic Achilles ruptures has necessitated a review that systematically maps and summarises current evidence regarding treatments and identifies areas for future research. This scoping review aims to improve knowledge of various treatment strategies and their associated outcomes, thereby aiding clinicians in optimising treatment protocols. Methods. The Arksey and O'Malley, Levac and Peters frameworks were used. A computer-based search in PubMed, Embase, Emcare, Cinahl, ISI Web of Science and Scopus was performed for articles reporting the treatment of chronic Achilles ruptures. Two reviewers independently performed title/abstract and full text screening according to a pre-defined selection criteria. Results. A total of 747 articles were identified, of which 73 were finally included. Various management strategies were described with flexor hallucis longus tendon transfer being the most common. The American Orthopaedic Foot and Ankle Society (AOFAS) score was the most commonly reported outcome, but 16 other measures were described within the literatures. All studies comparing pre- and post-operative outcomes reported a significant improvement. 50 studies reported complications, with an overall pooled complication rate of 168/1065 (15.8%). Conclusions. Beneficial results were reported following various techniques, but comparison between these was challenging due to the low-level study designs used and confounding factors including treatment delay and tendon gap size. Further research exploring the efficacy of different techniques is required to facilitate the development of evidenced-based treatment protocols. Such a work would allow for clinicians to better understand the suitability of specific techniques, thereby selecting the optimal management strategy for each individual patient

The purpose of this paper is to report on the use of a tendon transfer (anterior tibial to midfoot) to correct dynamic foot and ankle varus deformity. Anterior tibial tendon transfer to mid-foot is useful to consider in planning treatment where there is a need to rebalance a foot in which the unopposed or weakly opposed anterior tibial causes the abnormal varus position of the foot and ankle. 12 patients, 22 feet had anterior tibial tendon transfers performed. 10 were bilateral. 10 patients had neuromuscular disease as the underlying cause for the foot imbalance, 1 patient had idiopathic clubfoot with residual, recalcitrant varus after earlier posteromedial release and 1 patient was hemiplegic secondary to stroke caused by encephalopathy. Age of the patients at the time of their initial procedure(s) ranged from 2 to 34. There was at least 1 year follow-up after each procedure for the patient to be entered into this study. A 1-grade functional loss was encountered following tendon transfer of anterior tibial muscles grading between 4–5. (4=good, 5=being normal). The transferred muscles allowed the dynamic varus deformity to be removed and the foot to become plantigrade. In its transferred position, it functioned to actively contract and contributed to give support of the ankle. After an initial period of cast use post-operatively and bracing for 6 months to support the transfer, continued use of AFO was no longer necessary. Anterior tibial tendon transfer to mid-foot, originally described by Garceau continues to be an useful method for rebalancing a foot in which the abnormal pull of the normal or almost normal functioning anterior tibial muscle. This muscle is unopposed or weakly opposed because of the underlying neuromuscular disorder or previous surgery. Thus, it causes the foot and ankle to turn into varus. The technique used is straightforward and simple. It is a useful procedure to consider when rebalancing a foot may be needed

Aims. Flexor hallucis longus (FHL) tendon transfer is a well-recognized technique in the treatment of the neglected tendo Achillis (TA) rupture. Patients and Methods. We report a retrospective review of 20/32 patients who had undergone transtendinous FHL transfer between 2003 and 2011 for chronic TA rupture. Their mean age at the time of surgery was 53 years (22 to 83). The mean time from rupture to surgery was seven months (1 to 36). The mean postoperative follow-up was 73 months (29 to 120). Six patients experienced postoperative wound complications. Results. The mean postoperative Achilles tendon Total Rupture Score (ATRS) was 83 (40 to 100) and the mean American Orthopaedic Foot & Ankle Society (AOFAS) score was 94.3 (82 to 100). Tegner scoring showed a mean reduction of one level from the pre-injury level of activity. There was a mean reduction of 24% (4 to 54) in dynamometer-measured strength of ankle plantarflexion, in comparison with the non-operated side. The hallux had a mean of only 40% (2 to 90) strength of plantarflexion in comparison with the contralateral side. Conclusion. We conclude that transtendinous FHL transfer for neglected TA ruptures, with a long harvest to allow reattachment of the triceps surae, provides reliable long-term function and good ankle plantarflexion strength. Despite the loss of strength in hallux plantar flexion, there is little comorbidity from the FHL harvest. Cite this article: Bone Joint J 2018;100-B:584–9

Aims. To evaluate the donor site morbidity and tendon morphology after harvesting whole length, full-thickness peroneus longus tendon (PLT) proximal to the lateral malleolus for ligament reconstructions or tendon transfer. Methods. A total of 21 eligible patients (mean age 34.0 years (standard deviation (SD) 11.2); mean follow-up period 31.8 months (SD 7.7), and 12 healthy controls (mean age, 26.8 years (SD 5.9) were included. For patients, clinical evaluation of the donor ankle was performed preoperatively and postoperatively. Square hop test, ankle strength assessment, and MRI of distal calf were assessed bilaterally in the final follow-up. The morphological symmetry of peroneal tendons bilaterally was evaluated by MRI in healthy controls. Results. Among the patients, the mean pre- and postoperative American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score and Karlsson-Peterson score were 98.7 (SD 2.5; p = 0.480) and 98.5 (SD 2.4; p = 0.480), and 98.3 (SD 2.4; p = 0.162) and 97.9 (SD 2.5; p = 0.162), respectively. There was no significant difference between square hop test bilaterally (p = 0.109) and plantar flexion peak force bilaterally (p = 0.371). The harvested limb had significantly less eversion peak force compared to the contralateral limb (p < 0.001). Evidence of probable tendon regeneration was observed in all the patients by MRI and the total bilateral peroneal tendon index (mean ratio of harvested side cross-sectional area of peroneal tendon compared with the contralateral side) was 82.9% (SD 17.4). In 12 healthy controls, peroneal tendons (mean 99.4% (SD 4.3) were found to be morphologically symmetrical between the two sides. Conclusion. The current study showed satisfactory clinical foot and ankle outcomes after full-thickness PLT harvesting and indicated the regenerative potential of PLT after its removal. Level of Evidence: Level IV, therapeutic retrospective case series. Cite this article: Bone Joint J 2020;102-B(2):205–211

Introduction: In orthopaedic surgery, tendon transfers are used routinely. Examples are the correction of deformities due to spasticity in infantile cerebral palsy or clump foot surgery. Aftertreatment is not evidence based but depends mostly on the surgeons personal preferences. This is especially true for the duration of postoperative immobilization. Adhesions between tendon and surrounding tissue are supposedly a key factor for reduced functionality after immobilisation and it appears to be common sense that the amount of scarring depends on the duration of immobilisation. The purpose of this study was to determine the optimal (im)mobilisation schema, protecting the suture as well as avoiding impairment of the capability of the transferred tendon to slide properly. Methods: A tendon transfer of the m. flexor digitorum longus to the dorsal talus was performed in 32 New-Zealand rabbits. The tendon was passed through a drill hole and sutured to itself. Animals were randomised into 6 groups. Groups 1 to 3 experienced mobilisation of varying duration (none, 2 and 4 weeks) after two weeks of immobilisation. Groups 4 to 6 received the same time of mobilisation (4 weeks) but after different periods of immobilisation (4, 6, 8 weeks). Histomorphological examinations including synovial cell coating, appearance of tendon and tissue interface, inflammation and scarring of the site of surgery were done. The results were analyzed statistically (Kruskal-Wallis-test; Jonckheere Terpstra-test). Results: Except a difference in development of a synovial cell coating of questionable clinical significance there were no significant findings regarding the histomorphology between the different groups. Conclusion: In opposition to traditional believes, our results suggest that the influence of postoperative mobilisation or immobilisation towards the formation of scarring and adhesions in tendon transfers may by widely overestimated. This implies that the decision for the duration of postoperative immobilisation should be mainly based on safe ingrowths, without the imminent risk of loss of function

In recently, reverse shoulder arthroplasty for rotator cuff deficient arthritis is widely used in the world. However, a high complication rate was reported and worried about long-term results after reverse shoulder arthroplasty. From 2001, we performed a novel strategy for these cases such as rotator cuff reconstruction w/ or w/o muscle transfer and a humeral head replacement with using smallest head to decrease joint volume. The aim of this study was to investigate with clinical outcomes after this surgery more than two years follow-up. Materials & methods. Fifty six shoulders underwent humeral head replacement (HHR) with or without tendon transfer for cuff tear arthropathy was able to follow-up more than two years. The mean age was 74 years (60 to 83 years). 42 cuff tear arthropathy, 6 RA, 5 re-tear after cuff repair with arthritis, and 1 arthritis after infection were included. Coracoacromial arch preserved Superior approach with preserving coracoacromial arch was used for replacement the humeral stem and head. Almost of the cases could be repaired with using a smallest head because of the height of humeral head and joint volume were decreased. However, when rotator cuff remained in irreparable condition, a latissimus dorsi tendon or a pectoralis major tendon from same shoulder was transferred for cuff reconstruction. The patients were divided by 2 groups; 36 shoulders of HHR without tendon transfer and 20 shoulders of HHR with tendon transfer. Each patient was evaluated with Japan Orthopaedic Association score (JOA score) and modified Neer's limited goals rating scale after a least 2 year of follow-up. Results. In all cases, preoperative severe pain was dramatically improved. JOA score improve from 40.2 preoperatively to 80.2 postoperatively. Twelve shoulders estimated as excellent in modified Neer's classification, 34 in satisfactory and 10 in unsatisfactory. Half of cases with RA were unsatisfactory results. Postoperative active flexion statistically improved compared to preoperative range of motion. Averaged postoperative flexion was 136 degrees (preop.;68.8) and postoperative external rotation was 28.6 degrees (preop.;13.2). However, there was no significant difference of external rotation in the HHR group between pre and postoperative evaluation. The radiographic evaluation showed four cases of glenoid erosion. One case had arthroscopic Suprascapular nerve release eight years after surgery. Conclusions. The current results were consistent with the prior studies. Our novel strategy is considered as one of useful procedure for cuff tear arthropathy. However, the case which classified with Seebauer type IIB should not be recommended

Fixation of tendon transfers about the foot in children typically involves creating a bone tunnel through which a suture is passed and tied over an external button. An internal suspension system, such as the Endobutton (Smith & Nephew) is an alternative fixation method which has demonstrated excellent fixation strength and minimal intraosseous tunnel displacement in various adult procedures. Application of the Endobutton technique has no risk of skin ulceration, does not require suture removal and may provide more secure fixation. The purpose of this study is to compare the biomechanical properties of the external button and Endobutton fixation techniques. Our primary outcome measure was intra-osseous displacement of the suture, during both static and dynamic loading, in cadaver feet. Nine adult cadaver feet were utilised. A bone tunnel was drilled in the lateral cuneiform and #1 braided non-absorbable suture was passed through the tunnel. One end was secured to a carabiner to be attached to the materials testing system and the other to the fixation device. The external button and Endobutton fixation techniques were tested once in each cadaver, randomising the order of testing to minimise bias. Each fixation technique underwent static and dynamic cyclic loading. A custom Matlab script was used to process video and materials testing system data. The relative displacement of the suture within the bone tunnel, as a function of time and load magnitude, was recorded during static and dynamic cyclic loading. Both fixation groups were analysed and compared for statistical significance using a paired T-test and an alpha value of 0.05. The Endobutton group had significantly less displacement within the bone tunnel, during both static and dynamic loading, than the external button. The average displacement during static loading was 0.42 mm for the Endobutton and 2.17 mm for the external button (p=0.0019). Similarly, during dynamic cyclic loading, the mean displacement was 0.32 mm for the Endobutton and 0.66 mm for the external button (p=0.0115). The Endobutton internal suspension technique demonstrates significantly less displacement during static and dynamic loading than the external button, during biomechanical testing in cadaver feet. The Endobutton may provide superior fixation than the traditional external button technique for tendon transfers in children. In addition, this technique avoids the risk of skin ulceration from the button and the need for suture removal

Most of the controversy surrounding management of the adult acquired flatfoot deformity revolves around the correction of Stage 2 deformity. Stage 1 deformity, uncommonly corrected surgically, involves tenosynovitis with preservation of tendon length and absence of structural deformity. Attempts at tenosynovectomy in light of structural deformity leads to operative failure, found in 10% of Teasdall and Johnson's 1992 patient population. Thus, with tenosynovectomy rarely becoming an operative situation, Stage 2 deformity becomes the mainstay of operative treatment of the adult flatfoot. Stage 2 deformity patients present with swelling medially, the inability to do a single heel raise, with a passively correctable subtalar joint. The tendon is functionally torn. In recent years, authors have subdivided Stage 2 deformity even further into A and B subcategories, where A involves less than 50% uncovering of the talonavicular joint, and B patients more than 50%. Recently, Anderson has added a C subtype, which may be applied to either A and B patients, in patients who have forefoot varus. Thus, Stage 2 patients suffer from pain that begins medially and progresses to the subfibular region over time. Most important, recognition of the continued sub classification in Stage 2 disease echoes the fact that this disorder is on a continuum, challenging the surgeon to recognize subtleties that, if unrecognized, lead to a poor patient outcome. The mainstay of treatment in Stage 2 disease is the medial slide calcaneal osteotomy, which realigns the hindfoot axis reducing valgus, improves the medial arch, protects the FDL tendon transfer, and allows the Achilles tendon to become a strong inverter. Over shift of the calcaneus can compromise the outcome, as will a lack of recognition of the congenital subtleties such that a valgus hindfoot can have a varus orientation to the calcaneus, both leading to lateral overload. A pure medial slide of a calcaneus that has a varus orientation does not correct deformity, rather, it creates it. Thus, an axial calcaneal view must be studied carefully, for a varus orientation may be corrected via a closing wedge osteotomy commensurate with the medial shift of the tuberosity. As noted above, the flexor digitorum longus tendon transfer is the staple procedure to replace the damaged posterior tibial tendon. This transfer balances the eversion power of the peroneal tendons, works in phase with the former posterior tibial tendon in the stance phase of gait, and replaces a painful diseased posterior tibial tendon. However, over tensioning the transfer results in a tenodesis rather than a functional tendon transfer, the relative weakness of the FDL tendon (30% as strong as the PTT) creates difficulty with heel raise, and inappropriate transfer to distal tarsal bones may compromise the result by limiting torque from the transferred tendon. Preservation of the posterior tibial tendon in combination with the transferred FDL tendon remains a consideration without answer, though Rosenfeld (2005) suggests a substantial improvement in strength through PTT preservation. Failure of the above protocol for treating Stage 2 disease most often revolves around the insufficient corrective power of the tandem procedures in longstanding ruptures. According to Guyton (2001), only 50% of patients report a perception in deformity improvement following FDL/calcaneal osteotomy procedures, and only 4% report a significant improvement in pre-existing deformity. Sangeorzan (2001) found such patients could not achieve a painless plantigrade foot due to acquired ligament laxity (primarily the Spring Ligament). Sangeorzan applied Evans' pediatric procedure to adults without confirming the pathomechanics of correction. Some speculate the windlass effect on the plantar fascia creates correction (refuted by Horton, 1998, finding the plantar fascia is loosened by a lateral column lengthening), others believe tightening the peroneus longus through lateral column lengthening increases first ray plantarflexion, restoring the medial arch. Controversy also remains in answering Cooper's (1997) claim that lengthening through the calcaneus creates static increase in pressure about the calcaneocuboid joint (1.4mPa total) that may lead to an arthritic joint long term. Painful lateral overload following lateral column lengthening remains difficult problem to both prevent and correct. This last point leads to some focusing their efforts on restoration of the medial column. This group focuses on the “C” type deformity noted by Anderson, those with forefoot varus. It is known that the medial column is supported by the navicular, the cuneiforms, and the first, second, and third metatarsals. While a Cotton (opening wedge medial cuneiform) osteotomy, a first tarsometatarsal joint arthrodesis, or a metatarsal osteotomy has value, the surgeon must note that this only corrects the first ray. Complete correction of the medial column is best achieved through naviculocuneiform joint arthrodesis. Standing radiographs commonly reveal collapse at that level; however, surgeons are reticent to perform such fusions in light of the higher nonunion rate

Pediatric hand surgery in general requires special considerations and this is even more true when planning surgery in children with CP. It is important for the surgeon to realize that the functional problems these children exhibit have their cause in a brain damage which is not amenable to hand surgical treatment. Therefore it is crucial to carefully analyze each child’s impairment including the voluntary motor control and the child’s specific needs before endeavoring into surgery. Associated impairments, such as mental retardation, nutritional problems, epilepsy, dystonia or severe sensory deficits may influence decision-making, but the crucial factor is often the child’s own wish for an improved function. A child that completely neglects his or her extremity is usually not helped by surgery, at least not in an attempt to get a better hand function. Hand surgery in CP mainly comes down to three techniques: 1. Reducing strength in spastic muscles by release operation, either at the origin of the muscle, at the insertion or as a fractional lengthening at the musculo-tendinous junction, 2. Increasing strength in weak antagonists by tendon transfer or 3. Stabilizing joints through an arthrodesis or a tenodesis. Most often a combination of these techniques is used. Almost all hand surgeons in this field have acquired their personal choice of procedures and scientific support for the benefits of the different techniques is scarce. My personal arsenal will be described in the panel but includes biceps-brachialis muscle release at the elbow, pronator teres rerouting, flexor carpi ulnaris to extensor carpi radialis brevis (Green’s) transfer and adductor pollicis muscle release in the palm combined with extensor pollicis longus rerouting for the thumb-in-palm deformity. In my mind, it is not most important which tendon transfer that is selected, but the choice of which child to operate and at what age. It is also important to tension the tendon transfers exactly right and to plan the postoperative treatment properly. The surgeon should, of course, also make sure that the child’s and the parent’s expectations on the results are realistic. Botulinum toxin A has now been used for several years in the treatment of children with cerebral palsy and the drug has been shown to be safe and effective in reducing muscle tone both in the lower and the upper extremities. It has been more difficult to show effects on hand function especially in the long-term perspective. I will present our treatment protocol for botulinum toxin injections. In 1994, a population-based health care program for children with CP was started in Lund in southern Sweden. All children in our region with a diagnosis of CP, born after Jan 1st 1990 are invited to follow the program which includes regular measurements of range of motion in extremity joints, standardized radiographic examinations of the hip joints and registration of surgery and spasticity treatments. The program, called CPUP has been very successful in the prevention of spastic hip dislocation, wind swept position and contractures. Some early results from the upper extremity part of CPUP will be presented. We believe that the program in time will give us valuable information on the natural course of joint motion and impairment of hand function in children with CP

Chronic massive irreparable rotator cuff tears represent a treatment challenge and the optimal surgical technique remains controversial. Superior capsular reconstruction (SCR) has been proposed as a means to provide superior stability to the glenohumeral joint, thus facilitating restoration of shoulder function. However, despite the growing use of SCR there is a paucity of data evaluating the outcomes when performed using a dermal allograft. The purpose of this study was to (1) report the overall survival rate (reoperation and clinical failure) of SCR (2) evaluate for pre-operative factors predicting reoperation and clinical failure. From January 1, 2015 to November 31, 2017, 65 patients were diagnosed with irreparable rotator cuff tears and consented for a superior capsular reconstruction. These surgeries were performed by 6 surgeons, all fellowship trained in either sports or shoulder and elbow fellowships. Outcomes were graded as excellent, satisfactory, or unsatisfactory using the modified Neer scale. An unsatisfactory result was defined as a clinical “failure”. The Kaplan-Meier survival models were created to analyze reoperation-free and failure-free survival for the entire group. The reconstruction was performed using a dermal allograft. There were 31 patients excluded due to insufficient follow-up (< 6 months), leaving 34 included in this study. The mean follow-up was 12 months (range, 6–23). The average number of prior surgeries was 0.91 (range, 0–5), with 52.9% of patients receiving a prior rotator cuff repair and 38.2% of patients with a prior non-rotator cuff arthroscopy procedure. The one and two-year survival-free of surgery was 64% and 44% and the one and two-year survival free of failure was 34% and 16% following SCR, respectively. For the patients that underwent a reoperation, 62.5% (n= 5/8) underwent reverse shoulder replacements, 25% (n= 2/8) latissimus dorsi tendon transfers, and 12.5% (n= 1/8) a diagnostic arthroscopy. The average period between the primary and revision surgery was 10.2 months (range, 2.1–18.5). All but two patients (75%, n= 6/8) had at least one surgery prior to the SCR. There were 14/34 (41.2%) patients who experienced pain, weakness, and restricted range of motion. These patients were defined as clinical failures with an unsatisfactory grading on Neer's criteria. Previous surgery predicted reoperation (80% vs 43%, p = 0.03). Female gender predicted clinical failure (100% vs 43%, p < 0 .01). Superior Capsule Reconstruction performed for large to massive rotator cuff tears has a high rate of persistent pain and limited function leading to clinical failure in 65% (n= 22/34) of patients. The rate of failure is increased in revision cases, female gender and increased Goutallier fatty infiltration of the infraspinatus. Narrowed indications are recommended given the surgical complexity and high rate of early failure

The interosseous route remains popular for tibialis posterior tendon transfer for drop-foot. It leaves a smaller range of movement than the circumtibial route, but lengthening the calcaneal tendon may improve this. The results of this present series indicate that, in order to predict a good functional result, the ankle must be held in at least 20 degrees of dorsiflexion at the time of tendon transfer

Posterior tibial tendon dysfunction is a well-recognised condition. It commonly occurs in middle aged overweight women. In contrast to most tendon pathology, the tendon is still often intact and the tendon is stretched rather than completely ruptured. The diagnosis can be made on clinical grounds. Clinical features include acquired flatfoot deformity, inability to perform a single heel raise, ‘too many toes’ sign and loss of inversion power with the foot in forced plantarflexion. Disease is staged into four stages, Stage II is the most common presentation. Treatment options for Stage I are non-operatively including rest and antiinflammatories. Surgical treatment for this is required if this fails or progresses to next stage. Treatment for Stage II disease is most commonly a tendon transfer using FDL tendon transfer and some bony procedure, most commonly calcaneal osteotomy. More recently move to sub-classify Stage II into sub-classification depending on severity of hindfoot valgus and presence of fixed forefoot varus. Other treatment options for Stage II include lateral column lengthening or medial column shortening procedures. Stage III disease is fixed deformity which is classically treated with triple arthrodesis. Stage IV deformity is fixed deformity with ankle valgus. Difficult condition to treat. This requires ankle and hindfoot fusion

Purpose. Management of massive, degenerative, and irreparable rotator cuff tears is challenging. Excessive re-tear rates and poor clinical outcome after standard repair have led to alternative methods of treatment. Tendon transfers and shoulder arthroplasty have had mixed results; both are invasive procedures with high potential morbidity. We began performing rotator cuff augmentation and replacement using GraftJacket allograft acellular human dermal matrix as a biologic minimally invasive alternative in this difficult population almost 6 years ago. This article highlights our preferred arthroscopic technique and early results. Method. From January 2004 to June 2007, 45 patients (36 men, 9 women) with massive rotator cuff tears were treated arthroscopically with the GraftJacket allograft. All patients completed a preoperative University of California, Los Angeles (UCLA) score. Follow-up was a minimum of 2 years (range, 24–68 months) and patients completed UCLA, Western Ontario Rotator Cuff (WORC), and American Shoulder and Elbow Surgeons (ASES) scores. Results. Analysis was performed using the 3 validated outcomes measurement scores. The mean UCLA score increased from 18.4 preoperatively to 27.5 postoperatively (P < .000). The average WORC score was 75.2, and the ASES score was 84.1 at the final follow-up. Conclusion. Evidence-based data to outline an algorithm for management of irreparable rotator cuff tears is being developed. We documented significant clinical improvement with arthroscopic rotator cuff reconstruction using the GraftJacket allograft acellular human dermal matrix. The procedure is safe and associated with high patient satisfaction, without the morbidity of tendon transfer or arthroplasty. For those few cases where further surgery is required, no bridges are burned. The early success of this procedure warrants further study with more patients, longer follow-up, and higher levels of evidence-based investigation

We reviewed the results of a selective à la carte soft-tissue release operation for recurrent or residual deformity after initial conservative treatment for idiopathic clubfoot by the Ponseti method. Recurrent or residual deformity occurred in 13 (19 feet) of 33 patients (48 feet; 40%). The mean age at surgery was 2.3 years (1.3 to 4) and the mean follow-up was 3.6 years (2 to 5.3). The mean Pirani score had improved from 2.8 to 1.1 points, and the clinical and radiological results were satisfactory in all patients. However, six of the 13 patients (9 of 19 feet) had required further surgery in the form of tibial derotation osteotomy, split anterior tibialis tendon transfer, split posterior tibialis transfer or a combination of these for recurrent deformity. We concluded that selective soft-tissue release can provide satisfactory early results after failure of initial treatment of clubfoot by the Ponseti method, but long-term follow-up to skeletal maturity will be necessary

We reviewed the outcome of distal chevron metatarsal osteotomy without tendon transfer in 19 consecutive patients (19 feet) with a hallux varus deformity following surgery for hallux valgus. All patients underwent distal chevron metatarsal osteotomy with medial displacement and a medial closing wedge osteotomy along with a medial capsular release. The mean hallux valgus angle improved from −11.6° pre-operatively to 4.7° postoperatively, the mean first-second intermetatarsal angle improved from −0.3° to 3.3° and the distal metatarsal articular angle from 9.5° to 2.3° and the first metatarsophalangeal joints became congruent post-operatively in all 19 feet. The mean relative length ratio of the metatarsus decreased from 1.01 to 0.99 and the mean American Orthopaedic Foot and Ankle Society score improved from 77 to 95 points. In two patients the hallux varus recurred. One was symptom-free but the other remained symptomatic after a repeat distal chevron osteotomy. There were no other complications. We consider that distal chevron metatarsal osteotomy with a medial wedge osteotomy and medial capsular release is a useful procedure for the correction of hallux varus after surgery for hallux valgus

Various surgical treatment were reported on rheumatoid shoulder. However, there were no recommended surgeries in the Japanese 2. nd. basic published text of rheumatoid disease. We had performed total shoulder arthroplasty(TSA) and humeral head replacement (HHR) in patient with Rheumatoid shoulder from 1992. The aim of this study was to compare the outcome of humeral head replacement, 2. nd. generation TSA and 3. rd. generation TSA in patients followed more than 5 years with rheumatoid shoulder. Material & Method. From 1992–2007, we performed shoulder arthroplasty in 42 shoulders in 40 patients. Six cases were not able to follow due to die and lost. All 36 shoulders in 34 patients could be followed with x-ray examinations more than 5 years. Averaged follow-up period was 8.6 years (range 5–14.5). HHR with intact cuff performed in 10 shoulders, 2. nd. generation TSA with intact cuff in 10, 3. rd. generation TSA in intact cuff in 10 and HHR with muscle tendon transfer in 6 shoulders. The shoulder score of Japanese Orthopaedic Association)JOA score. Modified Neer classification, ROM, lucent lines in X-ray and complications were investigated. Results. In JOA score, 3. rd. generation TSA revealed highest score (84 points). Also, in Modified Neer classification, excellent results were obtained 50% of cases in 3. rd. generation TSA. On the other hand, HHR with muscle tendon transfer group has no cases of excellent results. In flexion & external rotation, 3. rd. generation TSA had achieved satisfactory results. In X-ray, all glenoid component had a lucent line around the keel type glenoid in 2. nd. generation TSA. However, only 1.6 points in Lazarus claasification revealed in peg type component in 3. rd. generation TSA. No nerve injuries and instability were found after surgery. However, two infections and two glenoid resurfacing need after surgery. Discussion. In this mid-term results, 3. rd. generation type of TSA system could get favorable results in RA shoulders with intact cuff. However, the treatment for rheumatoid shoulder cases which has masssive rotator cuff defect is still remained as difficult problem

Our aim was to determine whether the length and function of the flexor carpi ulnaris muscle were affected by separating it from its soft tissue connections. We measured the length of flexor carpi ulnaris before and after its dissection in ten patients with cerebral palsy. After tenotomy, tetanic contraction shortened the muscle by a mean of 8 mm. Subsequent dissection to separate it from all soft tissue connections, resulted in a further mean shortening of 17 mm (p < 0.001). This indicated that the dissected connective tissue had been strong enough to maintain the length of the contracting muscle. Passive extension of the wrist still lengthened the muscle after tenotomy, whereas this excursion significantly decreased after subsequent dissection. We conclude that the connective tissue envelope, which may be dissected during tendon transfer of flexor carpi ulnaris may act as a myofascial pathway for the transmission of force. This may have clinical implications for the outcome after tendon transfer

Purpose of the study: A stiff shoulder in internal rotation is a classical complication of obstetrical injury to the brachial plexus. The condition generally associates glenohumeral dysplasia. In 2003, Pearl proposed arthroscopic release of the shoulder, with or without latissimus dorsi transfer as an alternative to an open procedure. We report a series of 13 patients who underwent this procedure. Material and method: From 2004 to 2007, 13 children aged 1 to 11 years (range 3.5) underwent surgery. The procedure was an arthroscopic tenotomy of the intra-articular portion of the subscapularis associated with release of the anterior capsuloligament structures without tendon transfer. A thoracobrachial resin cast maintained the shoulder in maximal external rotation for six weeks. The functional outcome was assessed on the basis of the passive and active range of motion and the Mallet score. Pre and postoperative MRI was used to assess glenohumeral dysplasia and check its correction. Results: Mean follow-up was 23 months (range 5–40). There were no complications. Mean immediate postoperative gain was 53 (range 30–70) for external rotation (RE1). On average, passive RE1 improved from −5.4 to +57.7. Eight patients (61%) recovered active external rotation (57.5 on average). Mean active abduction improved from 45.8 to 56.5. Active internal rotation declined in 38% of the shoulders. The Mallet score improved in 69% of the shoulders. The best results were observed for children aged less than 4 years. There was one failure, related to major dyplasia which could not be reduced with an open procedure. Correction of the glenohumeral dysplasia was noted on 7 of the 9 MRI performed and the retroversion angle of the glenoid improved from −28.2 to −25.6, on average. Discussion: Open techniques are aggressive and only variably effective. A majority of our patients (8/13) achieved improved passive and active RE1 solely with the arthroscopic procedure. Correction of the glenohumeral dysplasia with growth appears to correspond to the clinical improvement but further follow-up is needed. Conclusion: Our results are comparable with those reported by Pearl. This is a minimally invasive easy-to-perform technique. For children aged less than 4 years, systematic tendon transfer does not appear to be necessary

We have reviewed 38 surgically treated cases of spontaneous posterior interosseous nerve palsy in 38 patients with a mean age of 43 years (13 to 68) in order to identify clinical factors associated with its prognosis. Interfascicular neurolysis was performed at a mean of 13 months (1 to 187) after the onset of symptoms. The mean follow-up was 21 months (5.5 to 221). Medical Research Council muscle power of more than grade 4 was considered to be a good result. A further 12 cases in ten patients were treated conservatively and assessed similarly. Of the 30 cases treated surgically with available outcome data, the result of interfascicular neurolysis was significantly better in patients < 50 years old (younger group (18 nerves); good: 13 nerves (72%), poor: five nerves (28%)) than in cases > 50 years old (older group (12 nerves); good: one nerve (8%), poor: 11 nerves (92%)) (p < 0.001). A pre-operative period of less than seven months was also associated with a good result in the younger group (p = 0.01). The older group had a poor result regardless of the pre-operative delay. Our recommended therapeutic approach therefore is to perform interfascicular neurolysis if the patient is < 50 years of age, and the pre-operative delay is < seven months. If the patient is > 50 years of age with no sign of recovery for seven months, or in the younger group with a pre-operative delay of more than a year, we advise interfascicular neurolysis together with tendon transfer as the primary surgical procedure

Transfer of pectoralis major has evolved as the most favoured option for the management of the difficult problem of irreparable tears of subscapularis. We describe our experience with this technique in 30 patients divided into three groups. Group I comprised 11 patients with a failed procedure for instability of the shoulder, group II included eight with a failed shoulder replacement and group III, 11 with a massive tear of the rotator cuff. All underwent transfer of the sternal head of pectoralis major to restore the function of subscapularis. At the latest follow-up pain had improved in seven of the 11 patients in groups I and III, but in only one of eight in group II. The subjective shoulder score improved in seven patients in group I, in one in group II and in six in group III. The mean Constant score improved from 40.9 points (28 to 50) in group I, 32.9 (17 to 47) in group II and 28.7 (20 to 42) in group III pre-operatively to 60.8 (28 to 89), 41.9 (24 to 73) and 52.3 (24 to 78), respectively. Failure of the tendon transfer was highest in group II and was associated with pre-operative anterior subluxation of the humeral head. We conclude that in patients with irreparable rupture of subscapularis after shoulder replacement there is a high risk of failure of transfer of p?ctoralis major, particularly if there is pre-operative anterior subluxation of the humeral head

Purpose: Mal-tracking or dislocation of the patella is often the result of abnormal anatomy. Understanding the abnormal anatomy will clarify the treatment options available. The common anatomical causes of dislocation range from the valgus knee with an elevated ‘Q’ angle to patella alta with a hypo-plastic trochlea, to external tibial torsion, resulting in an excessive ‘Q’ angle. External tibial torsion results in symptoms ranging from patello-femoral pain to subluxation or dislocation. Many patients are asymptomatic prior to an injury. The decision to correct the underlying anatomical abnormality is often a difficult one. Methods: A retrospective study of 232 rotational HTO’s in 221 patients operated on between 1990 and 2003 was conducted. The pre-operative degree of external tibial torsion and ‘Q’ angle was noted as well as the degree of rotation. The extent, if any patello-femoral pathology, was noted. Assessment was carried out using the HSS scoring system and Lysholm score.|Notation was made of prior surgery to the knee ranging from arthroscopy to patella tendon transfer to patellectomy. Results: Of the 232 cases 80% were good to excellent with resolution of patello-femoral pain and instability. 10% had residual pain but no instability and 20 cases had to proceed to total knee replacement.|The best results were seen in cases with pain and instability but minimal patello-femoral pathology. Even cases with end-stage patello-femoral osteoarthritis were improved by maximizing the function of the extensor mechanism. Conclusions: Rotational osteotomy of the proximal tibia for symptoms of patello-femoral instability secondary to significant external tibia torsion provided much better results than isolated patella tendon transfer

The surgical treatment of chronic Achilles tendon ruptures is essential to restore the normal gait pattern. There are a variety of surgical techniques described, including primary repair, augmentation with tendon transfers, augmentation with aponeurosis flaps and bridging techniques. In recent times augmentation with tendon transfers or aponeurosis flaps are the most commonly performed procedures. Our study examined the biomechanical effect of using the flexor hallicus longus in an augmented chronic Achilles tendon repair on gait pattern and forefoot loading distribution using pedobaragraphical analysis. We, pedobarographically examined the gait patterns of 10 patients who had undergone augmented chronic Achilles tendon repair using the flexor hallicus longus tendon. The mean age at the time of injury was 59 years of age (range 46–70). The mean follow-up time was 38 months. All patients reported good to excellent results. The mean AOFAS ankle score was 96.25 (range 90–100). There was no statistically significant difference between the loading distributions of the operated foot relative to the contralateral side. While there is no comparative study examining the outcomes of the varying surgical techniques for chronic Achilles tendon repair, the use of the flexor hallicus longus tendon in augmented chronic Achilles tendon repair has been proven as an effective repair to restore normal function while not compromising the biomechanics of the 1st ray or the loading distribution of the forefoot

Introduction: Cavus deformity of the foot is defined as equinus (plantar flexion) of the forefoot in relation to the hind foot. In 1/2–3/4 of the children an underlying disease could be diagnosed, usually neuromuscular in origin. Pathomechanism. Gradual developing deformity caused by muscular imbalance, the intrinsic muscles of the foot being weaker as well as the foot dorsiflexors. Main deformities are: claw toes, flexion of the first metatarsal, heel varus and equinus. The deformities will become more rigid with increasing growth and/or progression of the underlying disease. Symptoms are: shoefitting problems, pain, callosities under the forefoot and lateral border, clumsiness during gait and running, tripping. Predominant ages are 8 – 12. Diagnosis: The primary goal is to establish or role out an underlying disease before adequate treatment can be applied. The examination should focus on detailed muscle function and joint mobility. Standardised standing X-ray examination and EMG is often needed for diagnosis and to evaluate muscles to be transferred. Treatment: Moulded insoles, shoe modifications and AFOs are symptomatic. Preventing progression is important. In flexible feet tendon transfers is often sufficient. In rigid deformities various osteotomies is helpful. In the older teenager and adults triple arthrodesis combined with tendon transfers is often needed. Summary: Cavus foot is a common cause for foot problem in the growing child. Neuromuscular dysfunction has to be diagnosed. Surgical procedures are often needed

The recent advance of drug therapy for RA tends to replace preventive surgery, for example synovectomy. A rupture of a dorsal extensor tendon of the hand is an absolute indication for surgery, however. Such tendon ruptures are usually treated by tendon reconstruction and synovectomy of wrist joint. At our department, reconstructive surgery was administered with synovectomy for extensor tendon ruptures of the hand in 97 hands for 86 patients until June 2005. Recently, however, we occasionally encounter ruptures of extensor tendons not associated with severe synovitis. To treat such tendon ruptures, we usually administer tendon transfers in combination with tenosynovectomy through a small skin incision. Because this surgical procedure has achieved excellent results, we report our experience. This study included 15 patients who received tenosynovectomy in combination with tendon transfers in 14 hands since February 2001. This surgical procedure is indicated for tendon ruptures associated with mild synovitis (swelling) without instability on the ulnar distal end. As a rule, a 2–3 cm transverse skin incision was made on the dorsum of the hand under maxillary nerve block. After exposure of the distal ruptured end of the tendon, tenosynovectomy was administered through the incision. Then, the distal end was transferred to the adjacent normal tendon and fixed to it with sutures. Postoperatively, the repair was immobilized with bandage. The patient was allowed actively to extend and bend the hand on the next day. As a rule, this operation is administered on an outpatient basis. The postoperative course was uneventful, without rupture of the repair. The preoperative ranges of motion of the MP and PIP joints were retained postoperatively without difficulty in ADL

This study assessed the role of Ilizarov technique, using soft tissue distraction, in correction of radial club hand deformities. Five patients (6 deformities) with grade IV radial hemimelia (radial aplasia) were studied. There were three boys and two girls aged 2 to 8 years. One boy had bilateral involvement with TAR syndrome. One girl had bilateral involvement with VATER syndrome. One other boy had unilateral involvement with Holt Oram syndrome. The thumb was absent in three cases and hypoplastic in one case. The preoperative deformity measured 95 degrees (range 60–105 degrees). This was corrected using gradual soft tissue distraction with an Ilizarov fixator. Complete correction of the hand deformity was achieved over a period of 4–6 weeks. In two hands, rebalancing tendon transfers were performed in order to try and maintain correction. Following frame removal in both these patients, the deformity recurred despite splintage. Subsequently, four hands were treated with tendon transfers along with wrist stabilisation using intramedullary K-wires. The correction was maintained in all these cases. It is concluded that the Ilizarov technique can be used to achieve complete correction of radial club hand deformity but that correction can only be maintained by intramedullary stabilisation. The technique is well tolerated by patients and is more physiological when compared to the conventional treatment with wrist centralisation

Introduction: Children with clubfoot treated by the Ponseti method of clubfoot management require anterior tibialis tendon transfer if there is persistent varus and supination deformity. However the size of bone is a determining factor in whether this transfer can be carried out. We have assesses the difference in the age at which the lateral cuneiform ossifies in normal feet compare with clubfeet. Methods: Foot x-rays of children less than 4 years old (AP view) carried out between 2003 and 2005 were obtained from the Radiology department Booth Hall Children’s Hospital. A total of 341 radiographs were analyzed. Exclusion criteria included: any condition affecting foot anatomy or weight bearing or any previous surgery (including surgery for clubfoot). The lateral cuneiform was measured with 1mm accuracy in the longest diameter. Results: We analysed the size of the lateral cuneiform in patients with and without clubfoot in relation to age. In children without clubfoot there was a R2 value of 0.517, showing a positive correlation between age and size of the bone. In children with clubfoot, R2 value was 0.207 showing no correlation between age and ossification rate of the lateral cuneiform. In addition, we compare the size of the lateral cuneiform between patients with and without clubfoot at different ages. There was a significance difference in the level of ossification of the lateral cuneiform in all age groups. In addition, a greater number of patients with no ossification of the lateral cuneiform were found amongst the clubfoot group in all age groups up to the age of 36 months. Conclusions: We have identified a delayed ossification in the lateral cuneiform in children with clubfoot when compared with normal feet. This delayed ossification should be taken into account when considering anterior tibialis tendon transfer for correction of clubfoot

Introduction We report the experience of a district general hospital foot and ankle service, in performing a modified excision arthroplasty and tendon transfer to the metatarsophalangeal (MTP) joints of the lesser toes in both rheumatoid and non-rheumatoid patients. The procedure was carried out on 114 toes, in 58 feet of 55 patients over a 5-year period. Background Historically, partial proximal phalangectomy was complicated by recurrence of the extension deformity. . Stainsby (1990). described a technique of 7/8ths phalangectomy, repositioning of the plantar plate, extensor to flexor attachment and K-wire stabilisation to treat dislocated MTP joints of the lesser toes. However, it is recognised that the use of K-wires can be complicated by infection or premature removal. Angel reported the re-routing of the extensor tendon through a drill hole in the metatarsal head for MTP joint instability; this technique was attributed to Nigel Cobb. We have utilised the Stainsby technique and combined it with a Cobb tendon transfer to impart immediate stability to the toe, allowing K-wire fixation to be discarded. Technique Following a percutaneous proximal extensor tenotomy, a radical partial proximal phalangectomy (via a dorsal incision) reduces a dislocated MTP joint and the plantar plate is repositioned beneath a mobilised metatarsal head. A drill hole is then placed in the metatarsal head and the extensor tendon is re-routed from a plantar to dorsal direction. This maintains the reduction of the toe and provides interposition between the cut end of the proximal phalanx and the metatarsal head. Conclusion We believe that this modified combined technique is a reproducible alternative to the Stainsby procedure but, in addition, provides immediate stability of the MTP joint without the need for K-wire fixation

We studied a cohort of 26 diabetic patients with chronic ulceration under the first metatarsal head treated by a modified Jones extensor hallucis longus and a flexor hallucis longus transfer. If the first metatarsal was still plantar flexed following these two transfers, a peroneus longus to the peroneus brevis tendon transfer was also performed. Finally, if ankle dorsiflexion was < 5° with the knee extended, a Strayer-type gastrocnemius recession was performed. The mean duration of chronic ulceration despite a minimum of six months’ conservative care was 16.2 months (6 to 31). A total of 23 of the 26 patients were available for follow-up at a mean of 39.6 months (12 to 61) after surgery. All except one achieved complete ulcer healing at a mean of 4.4 weeks (2 to 8) after surgery, and there was no recurrence of ulceration under the first metatarsal. We believe that tendon balancing using modified Jones extensor hallucis longus and flexor hallucis longus transfers, associated in selected cases with a peroneus longus to brevis transfer and/or Strayer procedure, can promote rapid and sustained healing of chronic diabetic ulcers under the first metatarsal head

Chronic infections and ulceration around the tendo Achillis are difficult to manage. Split-skin grafts do not survive even on healthy exposed tendon. Refractory cases may require plastic surgical intervention with the use of free flaps. Patients with significant vascular disease are not suitable for such techniques. Flexor hallucis longus tendon transfer is an established treatment for chronic ruptures of the tendo Achillis. We report the successful treatment of an infected tendo Achillis with excision and reconstruction with flexor hallucis longus transfer. The muscle belly of this tendon allowed later skin grafting while the tendon transfer provided good functional recovery

A radial nerve palsy complicates 1.8 to 17% (mean 11%) diaphyseal humeral fractures (13.7% in our series of 156 humeral fractures and nonunions treated by external fixation – Tsiagadigui, 2000). In about 75%, it is a primary lesion, related to the fracture before any attempt at treatment. In 60%, the fracture, most commonly with an oblique fracture line, involves the middle third. In children, a supracondylar fracture may be complicated by radial nerve palsy. Most nerve lesions correspond to neurapraxia or axonotmesis, due to traction or compression associated with bone angular deformity. Unfrequently, the nerve is impaled or severed by bone fragments, or may be trapped within the fracture in case of a spiral oblique middle or distal third humeral fracture with lateral displacement of the distal fragment. Iatrogenic injury during internal fixation or entrapment within periosteal callus are occasionally observed. The classical indications for early radial nerve exploration include open fractures requiring surgical debridement, or fractures with vascular compromise, or when the osteosynthesis is done by a plate. In all other cases, we recommend to investigate the integrity of the radial nerve by echography. In the absence of discontinuity, spontaneous neurological recovery is likely to occur and is monitored clinically and by electromyography; prevention of joint contracture is done by physiotherapy and by a wrist splint, maintaining the joint in slight dorsiflexion. In case of persistent palsy, neurolysis is indicated several months after the initial injury, the precise delay depending on the level of the fracture. Palliative treatment by tendon transfers offers in cases of persistent palsy excellent functional results. Tendon transfers may be indicated early after the fracture, in case of an irreparable radial nerve lesion

The most commonly used surgical techniques used to treat recurrent or habitual patellar dislocation in the child do not specifically address the patella alta, one of the major causes of patellar dislocation. Twelve knees in eight patients had a lowering of the patella by total tendon transfer, lateral release and vastus medialis obliquus advancement. At two years of follow-up, only one knee had redislocated. Radiographically, the patellar height was anatomically restored in all other knees. All patients were pain free. This surgical technique is a good treatment option in the immature patient with recurrent or habitual patellar dislocation. Patella alta is one of the major causes known to predispose children to recurrent or habitual patellar dislocation. However, the surgical treatment of such a condition, before squeletal maturity, is rarely if ever mentioned in the literature. Twelve knees in eight patients were treated with a surgical procedure designated to correct patella alta, the major predisposing factor causing recurrent patellar dislocation. The technique involves lowering of the patella by total tendon transfer, lateral release and vastus medialis obliquus advancement. All patients were complaining of recurrent or habitual dislocations leading to functional disability. Patellar height was assessed radiographically by the Koshimoto index (PT/FT) and Caton-Deschamps index (AT/AP). The average at surgery was 10.9 years and mean follow-up was 45.1 months. Follow-up revealed redislocation in one knee. This patient required a second operation to achieve patellar stability. At the latest follow-up, all operated knees were functionally stable and pain free. The average preoperative ratios were 1.28 (PT/FT) and 1.53 (AT/AP) which improved to 0.97 (PT/FT) and 0.96 (AT/AP) at the time of follow-up. Few complications were noted. This technique is a valid surgical alternative to treat the immature patient presenting with functional disability related to recurrent or habitual patellar dislocation associated with patella alta

We hypothesised that a minimally invasive peroneus brevis tendon transfer would be effective for the management of a chronic rupture of the Achilles tendon. In 17 patients (three women, 14 men) who underwent minimally invasive transfer and tenodesis of the peroneus brevis to the calcaneum, at a mean follow-up of 4.6 years (2 to 7) the modified Achilles tendon total rupture score (ATRS) was recorded and the maximum circumference of the calf of the operated and contralateral limbs was measured. The strength of isometric plantar flexion of the gastrocsoleus complex and of eversion of the ankle were measured bilaterally. Functional outcomes were classified according to the four-point Boyden scale. . At the latest review, the mean maximum circumference of the calf of the operated limb was not significantly different from the pre-operative mean value, (41.4 cm, 32 to 50 vs 40.6 cm, 33 to 46; p = 0.45), and not significantly less than that of the contralateral limb (43.1 cm, 35 to 52; p = 0.16). The mean peak torque (244.6 N, 125 to 367) and the strength of eversion of the operated ankle (149.1 N, 65 to 240) were significantly lower (p < 0.01) than those of the contralateral limb (mean peak torque 289, 145 to 419; strength of eversion: 175.2, 71 to 280). The mean ATRS significantly improved from 58 pre-operatively (35 to 68) to 91 (75 to 97; 95% confidence interval 85.3 to 93.2) at the time of final review. Of 13 patients who practised sport at the time of injury, ten still undertook recreational activities. . This procedure may be safely performed, is minimally invasive, and allows most patients to return to pre-injury sport and daily activities. Cite this article: Bone Joint J 2015;97-B:353–7

Introduction and Aims: External tibial torsion associated with an increased ‘Q’ angle is an important factor in recurrent patella instability. It is surgically correctable with a rotational osteotomy of the proximal tibia above the patella tendon insertion. This technique ‘normalises’ the extensor mechanics and produces better results than patella tendon transfer. Method: Fifty-five patients were assessed with a minimum of five-year follow-up. Patients in this study underwent initial conservative treatment consisting of l2 months of physio. Those patients who continued to have recurrent instability underwent surgery. Only patients without rotational abnormalities of the femur were included. Tibial rotation was assessed geriometrically, with the degree of external rotational corrected to 20–23 degrees. Those patients with associated patella alta, underwent a distal transfer of the patella tendon also. Assessment included range of motion, thigh girth, quads strength, effusion and a modified Lystrom knee score assessed function and pre- and post-op radiographic assessment. Results: Ninety percent of the patients were female with an average of 30 (range 14–45). Prior unsuccessful surgical procedures included lateral release (l6) Maquet procedure (l0), Hauser procedure (l6) medialisation of patella tendon (l0), semitendinosis tenodesis and patellectomy (two). Post-operative follow-up average five to 8.2 years. Pre-operative external tibial torsion averaged 45 degrees (range 40–65 degrees) with an average rotational correction of 25 degrees. The average pre-op ‘Q’ angle was 27 degrees and post-op 14 degrees. Average pre-op functional score has 40 and post-op 70 degrees. Outcome assessment of the 55 knees showed 26 excellent, 16 good and 13 poor. Overall 76% of the knee were good – excellent. Of the 16 patients with associated anterior knee pain, 13 obtained good-excellent results. Patients with less painful symptoms pre-op, had significantly better outcomes. Knees that had undergone multiple unsuccessful surgical procedures, had significantly poorer outcomes. Uniplanar patella tendon transfer in these cases generally results in continued anterior knee pain. Conclusions: Derotational osteotomy re-aligned the extensor mechanism in cases of recurrent dislocation of the patella secondary to external tibial torsion. All patients had some improvement with the surgery, but the patients with poor outcomes continued to have anterior knee pain

Purpose: The synovectomy-reaxation-stabilisation (SRS) procedure classically involves tenosynovectomy of the extensors, articulr synovectomy, partial deinnervation of the wrist, and tendon transfer. The purpose of this study was to: 1) evaluate functional and radiographic results, 2) search for possible correlations between results and the extent of articular synovectomy or type of tendon transfer. Material and methods: Between 1984 and 1998, an SRS procedure was performed in 75 patients, 14 were excluded: seven had died, five were lost to folow-u and two had had wrist arthrodesis. A total of 73 wrists were analysed in 61 patients. Mean follow-up was 70 months and mean patient age was 53 years. Functional assessment was based on the Gschwend pain scale. Results: Before surgery, 94% of the patients had grade III or IV pain. At last follow-up, 93% of them grade 0 or I. The gain in pain was greatest for patients with severe carpitis. At last follow-up, the wrist was stiff; stiffness basically involved flexion with 43° pre and 27° postoperatively, radial inclination 13° pre and 9° postoperatively, and pronation in patients with advanced Larsen grade preoperatively. Extension, ulnar inclination, and supination were improved 5° to 10°. Extension of the synovectomy to carpal joints had a stiffening effect. Before the operation, 25 wrists were in Larsen grades 0, 1 and 2 and 48 wrists were in Larsen grades 3 or 4. At last follow-up, there were nine wrists in Larsen grades 0, 1, or 2 and 64 in Larsen grades 3 or 4. Carpitis thus continued to evolve and the height of the carpus declined. Ulnar translation of the carpus progressed a mean 2 mm. Spontaneous radial inclination of the wrist was aggravated by a mean 3°. The frontal position of the wrist was better after transfer of the long radial extensor of the carpus on the short radial extensor of the carpus than for transfer on the ulnar extensor of the carpus or without transfer. Discussion: Our pain results are in agreement with data in the literature but we did not observe preserved or improved mobility. Extended synovectomy appeared to have a stiffening effect. Progression of the ulnar translation of the carpus was less pronounced with simple resection of the head of the ulna. It was better to transfer the long radial extensor of the carpus on the short radial extensor of the carpus to correct for frontal deviation of the carpus

Reverse total shoulder arthroplasty (RTSA) was designed to treat the cuff-deficient shoulder with arthritis and irreparable rotator cuff tears of the supraspinatus and infraspinatus tendons. The results of RTSA in this patient population have been very good and reliable in the majority of cases. However, it has also been reported that patients whose rotator cuff tear involves the supraspinatus, infraspinatus and teres minor and who demonstrate a ‘horn-blower's sign’ do very poorly if a muscle transfer is not performed to improve external rotation in these shoulders in abduction. The loss of the teres minor in these patients results in grave difficulty for the patient attempting to perform their activities of daily living even if they can obtain reasonable good forward flexion. The muscle transfer that is most commonly used for these select patients is a latissmus dorsi tendon transfer in conjunction with RTSA. The purpose of this talk is to review the pathology of this problem and review the technique for its surgical treatment

The Cobb Stainsby forefoot arthroplasty for claw and hammer toes combines excision arthroplasty (Stainsby) with extensor tendon transfer to the metatarsal head (Cobb). We present a retrospective, three surgeon case series of 218 toes in 128 patients over four years. Clinical notes were reviewed for all patients and 77 could be contacted for a telephone survey. Follow up ranged from 12–82 months. All patients presented with pain and shoe wear problems from dislocated metatarsophalangeal joints either from arthritis, hallux valgus, Freiberg's disease or neurological disorders. Ipsilateral foot procedures were performed simultaneously in 24 (30%) patients. Seventy-two patients (94%) were satisfied, 72 (94%) reported pain relief, 55 (71%) were happy with toe control, 61 (79%) were pleased with cosmesis, 59 (77%) returned to normal footwear and 56 (73%) reported unlimited daily activities. Minor complications occurred in 17 (13%) and 3 (2%) developed complex regional pain syndrome. Four (5%) developed recurrent clawing. The Stainsby procedure permits relocation of the plantar plate under the metatarsal head for cushioned weight-bearing but can create a floppy, unsightly toe. By combining this with the Cobb procedure, our case series demonstrates improved outcomes from either procedure alone with benefits over alternatives such as the Weil's osteotomy. Oxford Level 4 evidence – retrospective case series

Introduction. Definition-in this presentation, the discussion will not include reparable cuff deficiency, as this is handled with standard arthroplasty techniques combined with cuff repair. Factors that affect decision-making. Kinematics-fixed fulcrum or not. Bone loss. Deltoid integrity. Coracoacromial arch integrity. Age. Activity level. Options. Hemiarthroplasty. “ Extended head” hemiarthroplasty. Arthroplasty + tendon transfer. Constrained arthroplasty – currently not FDA approved in USA. Arthrodesis. Evaluation. History and physical examination. ? Prior surgery. ? Overhead function – does fixed-fulcrum kinematics exist even if the head is not centred. ? Anterosuperior instability – lack of fixedfulcrum kinematics. Cuff strength. Deltoid integrity. Radiographs – bone loss, especially glenoid. Other imaging studies not necessary. Arthroplasty. Hemiarthroplasty. Best if fixed fulcrum kinematics exists – intact CA arch, intact deltoid, at or above shoulder elevation. Technical considerations. Preserve deltoid. Preserve coracoacromial ligament, acromion. ? Preserve remaining subscapularis – make humeral cut superiorly, through the rotator cuff defect. Alternatively, take down subscapularis and capsule in one layer, mobilise and repair or transpose superiorly. Increase retroversion of humeral cut- be careful of posterior cuff (teres minor) attachment. Glenoid deficiency – especially if anterior or anterosuperior instability is present. May need to graft glenoid with head. Humeral head size-the same size or slightly larger than the one removed; avoid overstuffing. “Extended head” hemiarthroplasty (CTA head). Indications same as hemiarthroplasty. Advantages. Provides resurfacing of greater tuberosity, which is articulating with the acromion and often irregular. Potentially improves kinematics by providing a “pain free” fulcrum. Technical considerations. Difficult but not impossible to do through a superior, subscapularis sparing approach. Special jig required for cutting tuberosity. Preserve CA arch. Preserve deltoid. Increase retroversion (be careful of remaining posterior cuff attachment). Glenoid deficiency – especially if anterior or anterosuperior instability is present. May need to graft glenoid with head. Humeral head size-the same size or slightly larger than the one removed; avoid overstuffing. Hemiarthroplasty + tendon transfer. Indications. Complete subscapularis deficiency. Posterior cuff insufficiency with anterosuperior subluxation or dislocation. Techniques. Latissimus transfer – posterior cuff insufficiency. Pectoralis major transfer – subscapularis insufficiency. Deep to conjoined tendon (Resch). Superficial to conjoined tendon (Rockwood and Wirth). Combined. Constrained arthroplasty. Not FDA approved in US. Delta III – reverse prosthesis. Reasonable results with medium-term follow-up in Europe (5–10 years). Rehabilitation. Limited goals. Primary goals are pain relief and stability. Passive flexion to 90°, passive ER to 30° for 4 weeks. Advance stretches and add active range of motion and active assisted range of motion (overhead pulley) at 4 weeks. Strengthening – 6 weeks. Results. Less predictable and less functional overall than most other disease categories (e.g., OA). Average elevation in most series is 120°. Usually good pain relief except in patients with anterosuperior subluxation

The Ponseti method of clubfoot management requires a period of bracing in order to maintain correction. This study compared the effectiveness of ankle foot orthoses and Denis Browne boots and bar in the prevention of recurrence following successful initial management. Between 2001 and 2003, 45 children (69 feet) with idiopathic clubfeet achieved full correction following Ponseti casting with or without a tenotomy, of whom 17 (30 clubfeet) were braced with an ankle foot orthosis while 28 (39 clubfeet) were prescribed with Denis Browne boots and bar. The groups were similar in age, gender, number of casts and tenotomy rates. The mean follow-up was 60 months (50 to 72) in the ankle foot orthosis group and 47 months (36 to 60) in the group with boots and bars. Recurrence requiring additional treatment occurred in 25 of 30 (83%) of the ankle foot orthosis group and 12 of 39 (31%) of the group with boots and bars (p < 0.001). Additional procedures included repeat tenotomy (four in the ankle foot orthosis group and five in the group treated with boot and bars), limited posterior release with or without tendon transfers (seven in the ankle foot orthosis group and two in the group treated with boots and bars), posteromedial releases (nine in the orthosis group) and midfoot osteotomies (five in the orthosis group, p < 0.001). Following initial correction by the Ponseti method, children managed with boots and bars had far fewer recurrences than those managed with ankle foot orthoses. Foot abduction appears to be important to maintain correction of clubfeet treated by the Ponseti method, and this cannot be achieved with an ankle foot orthosis

Introduction. Patients with neglected rupture of the Achilles tendon typically present with weakness and reduced function rather than pain. Shortening of the musculotendinous unit and atrophy of the muscle belly in chronic rupture potentially leads to poorer recovery following tendon transfer. Few papers have looked at the outcomes of FHL reconstruction specifically in neglected TA rupture. Of those that have none report functional outcomes following a transtendinous repair. Methods. Twenty patients with irreparable unilateral tendoachilles ruptures treated with transtendinous FHL reconstruction between 2003 and 2011 were reviewed. Achilles Tendon Rupture Score (ATRS), AOFAS hindfoot score, Tegner score and SF12 were recorded. Standard isokinetic assessment of ankle plantarflexion was performed with a Cybex dynamometer. Great toe flexion strength was tested clinically. Results. The mean age at surgery was 53 years (22–83 years). Mean time from rupture to surgery was 7 months (1–36 months). Follow up ranged from 29–120 months (mean 73 months). Sixteen patients were completely satisfied and four moderately satisfied. The mean ATRS was 80 (range 25–100) and AOFAS 94 (range 82–100). Postoperative Tegner score showed a reduction by one level from pre-injury (mean 5.1 pre injury to 4.3 post surgery). No cases of re-rupture were encountered. Six patients had wound issues. The mean maximal strength of ankle plantar flexion on the operated leg 95Nm (41–163) was less than the non-operated leg 123 Nm (50–190Nm). The average difference in strength was 24%. The operated hallux had only 40% of strength in flexion of the contralateral toe. There were no floating toes. Conclusion. Transtendinous FHL transfer for late presenting Achilles tendon ruptures provides reliable long term function and reasonable ankle plantar flexion strength. Long FHL harvest has little morbidity and lack of a distal tenodesis did not result in any notable functional loss or alignment issues to the great toe

Aims

Children with spinal dysraphism can develop various musculoskeletal deformities, necessitating a range of orthopaedic interventions, causing significant morbidity, and making considerable demands on resources. This systematic review aimed to identify what outcome measures have been reported in the literature for children with spinal dysraphism who undergo orthopaedic interventions involving the lower limbs.

The December 2022 Foot & Ankle Roundup³⁶⁰ looks at: Evans calcaneal osteotomy and multiplanar correction in flat foot deformity; Inflammatory biomarkers in tibialis posterior tendon dysfunction; Takedown of ankle fusions and conversion to total ankle arthroplasty; Surgical incision closure with three different materials; Absorbable sutures are not inferior to nonabsorbable sutures for tendo Achilles repair; Zadek’s osteotomy is a reliable technique for treating Haglund’s syndrome; How to best assess patient limitations after acute Achilles tendon injury; Advances in the management of infected nonunion of the foot and ankle.

Aims

There is a lack of high-quality research investigating outcomes of Ponseti-treated idiopathic clubfeet and correlation with relapse. This study assessed clinical and quality of life (QoL) outcomes using a standardized core outcome set (COS), comparing children with and without relapse.

Aims

To analyze the short-term outcome of two types of total wrist arthroplasty (TWA) in terms of wrist function, migration, and periprosthetic bone behaviour.

There are many reasons for muscle imbalance around the foot and ankle but the most common is some form of neuromuscular disease. The etiology is obviously very important in the decision making of treatment options. One should be aware of the progression pattern of the disease or condition. The simplest imbalances to treat are those secondary to a static condition. The initial goal is to determine what force couples are available, what can be used, is it an in phase, or out of phase muscle you want to transfer. Next is to determine if there are any contractures that will have to be addressed and equally important whether there are fixed skeletal deformities present. No tendon transfer will be able to overcome a fixed bony deformity, and those should be corrected prior to transferring muscles

Introduction:. The cavovarus foot is a complex deformity caused by muscle imbalance, soft-tissue contracture and secondary bony abnormality. It is a combination of hindfoot, midfoot and forefoot deformity and the decision making process for surgical management can be difficult. The process of deciding which combination of procedures is required is often poorly understood. We present an algorithm to assist with this decision making. Methods:. We have analysed a single surgeon's experience of cavovarus foot correction, from a consecutive series of 50 patients over 5 years, to develop an algorithm to guide operative decision making. Cases included cavovarus deformity secondary to cerebral palsy, Friedreich's ataxia, Charcot Marie Tooth disease, post-traumatic contracture, post-cerebrovascular accident, iatrogenic post-surgery and physiological cavus. We have taken a systematic approach to each component of the deformity in order to generate the algorithm. Results:. To assist in rationalising the traditional ‘a-la-carte’ approach, our algorithm describes what we believe are the indications for a variety of surgical interventions, including soft tissue contracture release, osteotomies of the hindfoot, midfoot and forefoot, tendon transfer and soft tissue balancing, and arthrodesis. We detail the decision making process for each surgical option and give the reasons for each decision. We have also reviewed the available literature on this topic, to produce an evidence-based and useable tool for surgical planning. Conclusion:. The surgical decision making process in the management of the cavovarus foot is complex. We believe that this algorithm, based on extensive personal experience and up-to-date published evidence, provides a clear and proven framework on which surgical decision making can be guided and justified

The February 2023 Shoulder & Elbow Roundup³⁶⁰ looks at: Arthroscopic capsular release or manipulation under anaesthesia for frozen shoulder?; Distal biceps repair through a single incision?; Distal biceps tendon ruptures: diagnostic strategy through physical examination; Postoperative multimodal opioid-sparing protocol vs standard opioid prescribing after knee or shoulder arthroscopy: a randomized clinical trial; Graft healing is more important than graft technique in massive rotator cuff tear; Subscapularis tenotomy versus peel after anatomic shoulder arthroplasty; Previous rotator cuff repair increases the risk of revision surgery for periprosthetic joint infection after reverse shoulder arthroplasty; Conservative versus operative treatment of acromial and scapular spine fractures following reverse total shoulder arthroplasty.

Crossover second toe deformity is a multiplanar deformity derived from multiple etiologies with the common endpoint of metatarsophalangeal joint instability. The stability of the joint is compromised through laxity of the volar plate, secondary rupture of the lateral collateral ligament, and ultimately dorsal subluxation or dislocation of the metatarsophalangeal joint. The digital malalignment often includes a hammertoe deformity, but should not be confused with a routine clawtoe. Elimination of alternative diagnoses relies on precise palpation to negate Morton's neuroma, 2nd metatarsalgia, Freiberg's infraction, and 2nd metatarsal stress fracture. Radiographs assist in the diagnosis in not only eliminating the above mentioned differential diagnoses, but also in evaluating confounding anatomic variables such as hallux valgus, metatarsus primus varus, and metatarsal length. These variables may necessitate additional osteotomies in conjunction with ligament reconstruction to minimise recurrence. Operative intervention has revealed long term failure of secondary ligament reconstruction, mandating tendon transfers such as the flexor-to-extensor and the extensor digitorum brevis to support the repair. We will explore these techniques and subsequent modifications to achieve patient satisfaction

There are numerous causes of cavovarus feet, the most common of which are the hereditary motor and sensory peripheral neuropathies. Regardless of the underlying aetiology, cavovarus feet are caused by muscle imbalance. Often the imbalance is between a relatively strong tibialis posterior acting against a weaker peroneus brevis, and a relatively weak tibialis anterior being over powered by peroneus longus. Intrinsic muscle weakness and gastro-soleal tightness is common. After the failure of non-operative management, flexible deformity can be corrected with a combination of tendon transfers and osteotomies. Frequently surgical management of cavovarus feet involves a combination of calcaneal and first metatarsal osteotomies, peroneus longus to brevis transfer, transfer of tibialis posterior through the interosseous membrane to the dorsum of the foot, tendo-Achilles and plantar fascia lengthening and correction of toe deformities. The post-operative recovery is slow, but most patients achieve good functional results and report improvements in their activities of daily living

Increasingly often diagnosed by sophisticated investigation, rotator cuff disease may be treated conservatively or surgically. Surgical options are decompression alone, decompression and debridement, partial rotator cuff repair, full reconstruction, tendon transfer and prosthetic replacement. Emphasising the quality of the repair rather than the classification of the injury, this paper details the criteria used in reaching a decision about the type of surgical treatment. Clinical, radiological, ultrasonographic and arthroscopic findings are used. The prognosis is directly related to the repair
