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.

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

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.

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

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

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

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. 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

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

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

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

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

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

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

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
