Background. Ankle and hindfoot fusion in the presence of large bony defects represents a challenging problem. Treatment options include acute shortening and fusion or void filling with metal cages or structural allograft, which both have historically low union rates. Impaction grafting is an alternative option. Methods. A 2 centre retrospective review of consecutive series of 32 patients undergoing hindfoot fusions with impaction bone grafting of morselised femoral head allograft to fill large bony void defects was performed. Union was assessed clinically and with either plain radiography or weightbearing CT scanning. Indications included failed total ankle replacement (24 patients), talar osteonecrosis (6 patients) and fracture non-union (2 patients). Mean depth of the defect was 29 ±10.7 mm and mean maximal cross-sectional area was 15.9 ±5.8 cm. 2. Tibiotalocalcaneal (TTC) arthrodesis was performed in 24 patients, ankle arthrodesis in 7 patients and
Muller-Weiss disease is an uncommon condition with unclear etiology and no gold standard treatment. The question arises; which joints to fuse? Although no consensuses prevail, one must postulate fusion should include those affected. Consequently, to establish an algorithm for its surgical management we set out to study clinical and radiographic features with use of SPECT-CT and a literature review. 57 consecutive feet presenting with Muller-Weiss disease analysed; 15 men, 25 women, age 22–84. Condition bilateral in 17, left side 16, right in 7 patients. Specific history and examination by senior author. Radiographic series and SPECT-CT obtained with surgery performed on significantly symptomatic feet. Measurements of Meary-Tomeno angles, anteroposterior thickness of navicular at the midpoint of each naviculo-cuneiform, alongside the medial extrusion distance and percentage of compression in each case performed. Poor correlation between Meary's angle and 1) degree of compression at naviculo-cuneiform joints, 2) degree of extrusion 3) compression vs extrusion using R. 2. coefficient of determination (invalidating Maceira et al. classification). In unilateral cases, extrusion significantly greater on affected side 94.7% (P< 0.001 Fisher exact test). Degree of extrusion significantly greater in bilateral than unilateral cases (p=0.004 unpaired T test). Valgus hindfoot and Meary's negative most common pattern with no correlation between heel alignment and Meary's R. 2. = 0.003. SPECT-CT useful to determine subtalar involvement in ‘stage 2 disease.’. Following review of cases and published literature we propose the following classification for Muller-Weiss disease with treatment algorithm. 3 Stage delineation; Stage 1 (Normal hindfoot alignment); 1A. Talonavicular disease only - Isolated Talonavicular arthrodesis 1B. Talonavicular + Subtalar; double medial or
Introduction: Recent studies suggest that preservation of the calcaneocuboidal joint and a single medial approach may lead to equally good results as a conventional
We have treated 14 patients (15 fractures) with nonunion of an intra-articular fracture of the body of the calcaneum. The mean follow-up was six years (2 to 8.5). A total of 14 fractures (93%) had initially been treated operatively with 12 (86%) having non-anatomical reductions. Four feet (27%) had concomitant osteomyelitis. Of the nonunions, 14 (93%) went on to eventual union after an average of two reconstructive procedures. All underwent bone grafting of the nonunion. The eventual outcome was a subtalar arthrodesis in ten (67%) cases, a

Between 1997 and 2002, seven talipes equino varus deformities in six patients were treated using gradual distraction and correction with the Ilizarov external fixator. Three patients had poliomyelitis, four patients had neglected clubfeet and two patients had relapsed club-feet. The mean age of patients was 13.3 years (5 to 21) and the mean duration of fixator application was 3.25 months. When the plantigrade position was achieved the fixator was removed and a below-knee walking cast was applied. Four months after fixator removal, additional bony correction surgery (triple arthrodesis) was done in three patients. At the time of fixator removal, a plantigrade foot was achieved in all patients. The mean follow-up time from surgery was 26 months. Pin-tract sepsis in two patients was treated effectively with oral antibiotics. Other complications included meta-tarsophalangeal subluxation from flexor tendon contractures in one foot. There have been no recurrences of deformities. Compared to preoperative status, gait was subjectively improved in all patients. Correction of the deformity in the patients who had a

A total of 38 relapsed congenital clubfeet (16 stiff, 22 partially correctable) underwent revision of soft-tissue surgery, with or without a bony procedure, and transfer of the tendon of tibialis anterior at a mean age of 4.8 years (2.0 to 10.1). The tendon was transferred to the third cuneiform in five cases, to the base of the third metatarsal in ten and to the base of the fourth in 23. The patients were reviewed at a mean follow-up of 24.8 years (10.8 to 35.6). A total of 11 feet were regarded as failures (one a tendon failure, five with a subtalar fusion due to over-correction, and five with a
Surgical resection of the persistently painful talocalcaneal tarsal coalition has not been shown to reliably relieve symptoms in patients with coalitions that are large and have associated hindfoot valgus and subtalar arthrosis. It has been recommended that these patients undergo
Introduction and Aims: Non-union following
Arthrodesis of both the ankle and the hindfoot has been discussed in the literature since the early part of the last century. Techniques have been modified substantially since these early discussions, though complications remain a frustrating element in patient management. Early procedures relied on molded plaster casts to hold fixation in corrected positions. Successful outcomes were hampered by loss of reduction in these casts and subsequent malunions. In addition, motion within these casts lead to a high rate of nonunion between the opposed bony surfaces. The era of internal fixation allowed compression across arthrodesis sites, enhancing union but creating a host of technical errors leading to unsatisfying results. Malunion is also seen in post-traumatic situations. In particular, non-operative management of calcaneus fracture (or other hindfoot fractures) leads to not only arthritis of the involved joint surfaces, but malunion complicating successful fusion. Fusion in-situ leads to a high level of patient dissatisfaction, leading surgeons to challenging deformity correction while trying to achieve successful arthrodesis in compromised joints. This lecture will focus on two types of malunion, one iatrogenic, one acquired. Revision
Background. Subtalar nonunion has a detrimental effect on patients' function, and pose a significant challenge for surgeons particularly in the setting of higher risk factors. Methods. We retrospectively analyzed a consecutive series of 49 subtalar nonunions between October 2001 and July 2013. Patient records and radiographs were reviewed for specific patient demographics and comorbidities, subsequent treatments, revision fusion rate, use of bone graft, complications, and clinical outcome. Results. Forty-nine patients with a mean age of 49 years (range 23–80) were included. Sixteen (32%) were heavy smokers (>1 pack per day) and five (10%) had diabetes. Forty one (84%) of the nonunions were symptomatic and underwent a revision procedure at a mean of 16 months (range 2.8 to 57) from the time of the primary arthrodesis. Four of these patients required a
Hindfoot fusions are not new and can be a very valuable tool to address a variety of hindfoot problems. It is, however, not a procedure without significant issues. With the combination of a subtalar and talo-navicular fusion most of the ability to compensate for uneven terrain is lost, as is the ability to compensate for minor misalignments in the foot itself. It is therefore extremely important to be diligent in planning and execution of a
The correction of a relapsed or neglected clubfoot by an external distractor is an alternative to a major operation which may involve
Eleven patients were reviewed an average of 23 years after they had been treated by excision of a symptomatic calcaneonavicular bar in 16 of their feet. Of these feet 69% (11 feet) had a good or excellent result. Of the five failures, three feet had good results after subsequent
We examined 16 feet, 33 to 133 months (mean 83) after simultaneous calcaneocuboid and talonavicular fusions performed for a variety of painful disorders of the hindfoot. Objectively, four feet were rated excellent, eight good, four fair and none poor. There was one asymptomatic nonunion of the talonavicular joint. Progressive degenerative arthritis of the ankle was seen in six patients and of the naviculocuneiform joint in seven. Biomechanically, simultaneous calcaneocuboid and talonavicular arthrodesis is better than an isolated talonavicular fusion and is a simple and effective alternative to
Introduction. Historically, surgeons have focused on isolated simple coalition resection in symptomatic tarsal coalition with concomitant rigid flat foot. However, a review of literature suggests that coalitions with severe preoperative planovalgus malposition treated with resection alone are associated with continued disability and deformity. We believe that concomittant severe flatfoot should be considered as much as a pathological component and pain generator as the coalition itself. Our primary hypothesis is that simple resection of middle facet tarsal coalitions and simultaneous flat foot reconstruction can improve clinical outcomes. Methods. Thirteen consecutively treated patients (eighteen feet) were retrospectively reviewed from the senior author's practice. Clinical examination, American Orthopaedic foot and Ankle Society (AOFAS) hindfoot scores, and radiographic assessments were evaluated after resection of middle facet tarsal coalitions with simultaneous flat foot reconstruction. Results. All patients with resection and simultaneous flat foot reconstruction (calcaneal lengthening, medial cuneiform osteotomy) were satisfied and would have the same procedure again. Most patients were able to return to a higher level of sporting activity compared with preoperative ability. None of the patients had a fair or poor outcome as adjudged by their AOFAS scores. Conclusion. Our study shows that concomittant flatfoot reconstruction in patients with symptomatic middle facet tarsal coalition increased hindfoot motion, corrected malalignment and significantly improved pain. We believe that coalition resection and concomitant flatfoot reconstruction is better option than surgical resection alone or hindfoot fusion in this cohort of patients.
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
Injuries involving the midtarsal joint, which are frequently misdiagnosed, have been studied to clarify the mechanism, classification and treatment. The necessity for routine antero-posterior, lateral and oblique radiographs is emphasised. Seventy-one injuries have been classified according to the direction of the deforming force : medial, longitudinal compression, lateral, plantar and crush types are described. Included in the medial and lateral types is a hitherto undescribed tarsal rotation or " swivel" injury. The mechanism whereby longitudinal compression causes fractures of the body of the navicular is described, and two varieties having different prognoses are defined : one due to purely longitudinal compression and the other due to longitudinal compression with a medial component. The results of treatment have been assessed clinically and radiologically. Reduction, open if necessary, with internal fixation, is recommended for displaced fractures : primary arthrodesis is not indicated. For severe persistent symptoms from medial and longitudinal force injuries
1. Sixty feet operated upon either by triple or pantalar tarsal fusion for instability after poliomyelitis were re-examined ten to twenty-four years later. 2. After triple fusion with preservation of the ankle joint there was a striking absence of late osteoarthritis of the ankle, and only a low incidence of troublesome lateral instability of the ankle. The results were generally good provided the patient had reasonable power of extension of the knee. 3.
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. 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.Aims

The aim of this study is to present guidelines for treatment of acquired adult flat foot (AAFF) and review the results of a series of patients consecutively treated. 180 patients (215 feet), mean age 54? 12 years affected by AAFF were evaluated clinically, radiographically and by MRI to chose the adequate surgical strategy. Tibialis posterior dysfunctions grade 1 were treated by tenolysis and tendon repair (48 cases), grade 2 by removal of degenerated tissue and tendon augmentation (41 cases), grade 3 by flexor digitorum longus tendon transfer (23 cases); in these cases subtalar pronation without arthritis was corrected by addictional procedures consisting of either calcaneal osteotomy (66 cases), subtalar athroereisis (25 cases) or Evans procedure (21 cases) in case of severe midfoot abduction. Subtalar arthrodesis (82 cases) or
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
Introduction: Recurrent clubfoot deformity continues to present a problem in pediatric orthopedic practice. Because of the complexity of feet deformation, the correction represents a significant challenge even for orthopedists having experience in work with the Ilizarov device. Materials and Methods: We apply the Ilizarov fixator consisting of a base from two rings on a shin, an anterior support on the foot – the half ring perpendicular to metatarsal bones and a posterior support from the extended half ring attached to the heel. Anterior and posterior supports are attached to the base by standard details of the Ilizarov apparatus and remain unconnected between them. Such a frame design allows independent and simultaneous correction of forefoot and hind-foot deformities. From 1999–2006, 9 patients aged 3–30, 13 feet with recurrent clubfoot were treated with this technique. Three patients were females and 6 were males. Closed correction was perform in 5 cases, mid-foot osteotomy 4 cases
Isolated arthrodesis of the subtalar joint has the advantage that it preserves some motion at the midfoot. In cadaveric studies, movement at the Talonavicular joint is reduced by up to 74% and at the Calcaneocuboid joint by up to 44%. This allows some midfoot flexibility, which would not occur with a
Introduction: Ankle Arthroplasty is an alternative to arthrodesis for patients with disabling ankle arthritis. It aims to remove pain and preserve joint motion. We aimed to review the outcome of all total ankle replacements carried out in our institution between 2002 and 2006. Materials and Methods: We retrospectively reviewed the results of all patients who underwent the Agility ankle replacement performed by a single surgeon. Case notes and radiographs were reviewed and outcome assessment included standardised questionnaires. Results: 30 arthroplasties were performed in 30 consecutive patient. 11 males, 19 females, Pre operative diagnosis was rheumatoid arthritis (16), primary osteoarthritis (12) and post-traumatic osteoarthritis (2) with a mean age of 61.8 yrs. 8 patients required an additional procedure at the time of arthroplasty : tendoachilles lengthening (6); Calcaneal osteotomy (2);
Purpose: In paediatric patients, autografts are limited by the quantity of available bony tissue in donor regions, the need for a second incision, the longer surgical time, and donor site morbidity. Bone substitutes would be an advantage in many cases. Serum and platelet autologous growth factors favouring osteo-induction can be obtained readily. When used in conjunction with osteoconductive materials, they can favour bone growth. The purpose of this work was to evaluate the use of combined autologous growth factors (AGF) and hydroxyapatite (HA) in paediatric patients instead of autologous grafts. Material and methods: This prospective study was conducted in 14 children (16 grafts), nine boys and six girls, mean age 9.4 years. These children required bone grafting related to femoral osteotomy, osteomyelitis, benign cystic tumours, bone nonunion,
Purpose of the study: The aim of this study was to evaluate the results of the repeated soft tissue release for recurrent postoperative idiopathic congenital talipes equinovarus. There is no real consensus on the appropriate therapeutic option. Materials and Methods: Fifty two patients (74 feet) underwent revision surgery performed by our senior surgeon between 1974 and 2001. One, two or three soft tissue release procedures were performed on 59, 12 and 3 feet respectively. Mean age at the time of the revision surgery was 5.7 years (range 15m-14y). Triple deformity (varus, equinus, adductus) was found in 46 feet, while 28 feet had one dominant deformity. The operation consisted of complete release of the soft tissues in 26 feet and partial release in 48. Subtalar release was indicated in 21 feet. Lichtblau osteotomy was performed in 48 feet. The clinical and radiological outcome was assessed using the Ghanem and Seringe scores recorded before surgery and at last follow-up. Results: Mean follow-up was 11 years (range 4–30). Complications included overcorrection in valgus (n=6) and recurrence (n=8). The anatomic correction was highly significant. Dorsoplantar X-rays show the improvements in the mean talocalcaneal divergence (18–21°), the mean talus-first metatarsal angle (reduced from 28° to 4°), and the calcaneus-fifth metatarsal angle (reduced from 20° to 2°). The average of tibiocalcaneal angle in lateral view increased from 1° to 10° and the average of calcaneal incidence from 6° to 9°. At last follow-up, outcome was considered as ‘excellent’ in 29% and ‘good’ in 42% of the cases. We had ‘fair’ results in 14 feet (19%) because of poor functional results in one third and anatomical defects in two-thirds of them. The outcome was considered ‘poor’ in seven feet (10%), which was due to significant anatomical defects.
The records of 82 patients (129 feet) with resistant clubfoot deformity treated surgically by means of different releases were retrospectively reviewed. There are many treatment regimes for clubfoot. Some authors recommend manipulation with minimal multi-stage surgery, whereas others recommend neonatal corrective surgery. However, objective comparison of different treatment programs is not easy because different criteria are used to evaluate the results. Teratologic or neuromuscular clubfeet were not included in this revision. Between 1982 and 1998, 82 patients (27 girls, 55 boys) with 129 clubfeet underwent surgical treatment. All feet were initially treated with a serial long-leg cast for a minimum of four months. Mean age at the time of first surgery was 5.5 months (range 3.5 to 24). Minimum follow-up was two years. Primary posterior release was performed on 105 feet. Subsequent medial release was performed on 16 feet, posteromedial release on three, and a subtalar (Cincinnati) release on three. Primary isolated posteromedial release was performed on 14 feet, and two of these required a subsequent subtalar (Cincinnati) release. Primary isolated medial release was performed on seven feet. Primary isolated lateral release was performed on one foot and primary isolated subtalar (Cincinnati) release was performed on two feet. Subsequent derotative tibial osteotomy was performed in seven cases, wedge tarsectomy on four feet,
Tibiotalocalcaneal (TTC) fusion is indicated in rheumatoid patients with combined ankle and subtalar disease, particularly when severe deformity is present. In theory, if bone stock is good, a staged subtalar/
Introduction: The mini C-arm is a compact, user-friendly device with the advantage of reducing exposure to ionising radiation compared to the conventional C-arm. Optimising radiation exposure is not only desirable, but also a legal requirement and protocols should be in place to achieve this. The purpose of this paper is to review our use of the mini C-arm for elective foot surgery and to suggest guidelines for optimising its use. Materials and Methods: Between 2004 and 2006, all elective foot surgery requiring intraoperative imaging were performed using the mini C-arm unit. Procedures performed included ankle, midfoot and hindfoot arthrodeses and joint injections or aspirations. Screening times and radiation doses were recorded for each procedure. Results: Following an initial learning curve, the screening times stabilised around the median value for the individual procedures. For a subtalar or
Introduction: The double-hindfoot arthrodesis (subtalar and midtarsal joints) is traditionally performed through a lateral surgical approach associated or not with a medial approach. The main goal of this procedure is to correct severe deformities of the hindfoot in varus or in valgus. In this study we report a series of 19 double-hin-foot arthrodeses through a single medial approach. Methods and Materials: 19 double arthrodeses (subtalar and talonavicular joint) were performed on 16 patients, 8 males and 8 females with a mean age at surgery of 58.3 years (range 27–72). The indications were: 12 pes planovalgus and 7 cavus foot. 9 deformities were fixed (3 in valgus and 6 in varus). The chosen surgical technique was always identical using a medial approach and performed by a single dedicated orthopaedic foot and ankle surgeon (JLB), followed by an osteotomy of the insertion of the Tibialis posterior muscle to the Navicular bone, distraction and avivement of the articular surface done without bone resection, reduction of the talus on the calcaneus, fixation of the talonavicular joint with titanium staples (Pareos®) and of the subtalar joint with two 6.5 mm canulated cancellous screws (Unima®). On five occasions (in 3 pes planovalgus and in 2 cavus foot) arthrodesis of the calcaneocuboid joint was carried out through a mini lateral approach due to painful arthritic lesions. Results: The average follow up was 16.5 months (range 6–40). Consolidation was always achieved. In the subgroup with pes planovalgus: the mean Kitaoka score increased from 44 to 75, the axis of the hind-foot decreased from 21° to 11° in valgus, Djian’s angle decreased from 142° to 134.4°, the slope of the calcaneus increased from 17° to 19.4°. Two failures of the associated medial ligament reparation have led to a secondary complementary arthrodesis of the talo-crural joint. In the subgroup with cavus foot: the mean Kitaoka score increased from 16 to 67. The axis of the hindfoot decreased from 13° in varus to 0.6° in valgus. Djians’s angle increased from 117° to 127.4°, the slope of the calcaneus ranges from 21.3° to 21.5°. Discussion: The double-hindfoot arthrodesis via a medial approach permits the fusion without developing nonunion (in comparison with 20% non-union of
Deltoid ligament insufficiency has been shown to decrease tibiotalar contact area and increase peak pressures within the lateral ankle mortise. Sectioning of the deltoid ligament has been shown to decrease tibiotalar contact area by 43%. This detrimental effect may create an arthritic ankle joint if left unresolved. Reconstructive efforts thus far have been less than satisfactory. Pankovich and Shivaram described the deltoid ligament as having superficial and deep components based on insertion sites. The superficial layer originates from the anterior colliculus of the medial malleolus and inserts on the navicular, calcaneus and talus. The deep layer originates from the intercollicular groove and posterior colliculus and inserts on the talus. Boss and Hintermann noted that the most consistent and strongest bands of the deltoid were the tibiocalcaneal and posterior deep tibiotalar ligaments. Chronic deltoid ligament insufficiency may be seen in several disorders including trauma and sports injuries, posterior tibial tendon disorders, prior
We analyzed the radiographic results of patients treated surgically for flatfoot deformity and who underwent medial cuneiform opening wedge osteotomy as part of the operative procedure. The aim of this study was to confirm the utility of the cuneiform osteotomy as part of the correction of hindfoot and ankle deformity. All patients requiring operative management of flatfoot deformity between January 2002 and December 2007 were prospectively entered in a database. We selected all patients who underwent medial cuneiform opening wedge osteotomy. We measured standardized and validated radiographic parameters on pre and post-operative weight bearing radiographs of the foot. All radiographs were assessed using the digital imaging software package (Siemens). The following measurements were used: lateral talus-1st metatarsal angle; medial cuneiform to floor distance (mm), talar declination angle, calcaneal-talar angle, calcaneal pitch angle, 1st metatarsal declination angle, talonavicular coverage angle, and anteroposterior talus-1st metatarsal angle. Other variables including concomitant surgical procedures, healing of the osteotomy, malunion, and adjacent joint arthritis were also noted. There were 86 patients with a mean age of 36 years (range 9–80). 15 patients had bilateral surgery. The aetiology of the deformity was flexible flat-foot in 48, rupture of the posterior tibial tendon in 41, rigid flatfoot deformity with a fixed forefoot supination deformity in 7, and fixed forefoot varus with metatarsus elevatus in 5. In addition to an opening wedge medial cuneiform osteotomy, a lateral column lengthening calcaneus osteotomy was performed in 80, a gastrocnemius recession in 76, a supramalleolar osteotomy in 2, a
Background: Heel valgus and flattening of arch are common in rheumatoid arthritis (RA). The progression of hindfoot valgus deformity results in pain and debilitating disability, and causes the excessive stress on the ankle joint. Subtalar arthrodesis is often indicated in these cases to reduce the pain and to correct the talocalcaneal alignment. However, accurate correction is not easy without bone grafting, because bone defect often appears after correction. Bone grafting is necessary for accurate correction in these cases, but we have avoided it because of following reasons; donor site problem like insufficiency fractures of pelvis, supply limitation of autograft for possible multiple operations during long term disease progression of RA and the lack of bone graft substitutes, which possesses enough osteoconductivity. Now we have developed the interconnected porous calcium hydroxyapatite (IP-CHA) which possesses good osteoconductivity and achieves major incorporation with host bone much more rapid than the other porous calcium hydroxyapatite. So, we evaluated the usefulness of the packing with the newly developed IP-CHA in bone defect after correction of pes planovalgus deformity of RA patients. Methods: The best possible correction of talonavivular alignment and fixation is performed using one cubic hydroxyapatite block (1x1x1cm), staple and Kirschner wire. Then granular IP-CHA is implanted in bone defect existing mainly in talar body, gap of talonavicular joint and sinus tarsi. Six planovalgus feet were treated with subtalar arthrodesis in 4 female RA patients (3;
The purpose of this study was to review the total ankle arthroplasties performed in consecutive series of 78 ankles and to determine the short-term results in cases with over 12 months follow-up. Preoperative diagnoses were post-traumatic osteoarthritis in 40 ankles (51.3%), primary osteoarthritis in 32 ankles (41.0%), and systemic arthritis in six ankles (7.7%). HINTEGRA. ®. (Newdeal SA, Lyon, France) total ankle system was used in all cases. Fifty-five total ankle arthroplasties including four revision cases, followed up for over 12 months (range, 13~49 months) were included in this study. Ankles were divided into three groups according to the coronal plane deformity in preoperative standing ankle AP radiograph; Varus (≥10°; 20 ankles (39.2%)), neutral (<
10° varus or valgus; 25 ankles (49%)), and valgus (≥10° valgus; 6 ankles (11.8%)). Various additional surgeries were performed simultaneously with the arthroplasty to correct the deformities; deltoid ligament release (25 cases), posterior tibialis tendon lengthening (2 cases), peroneus longus tendon transfer to brevis (5 cases), lateral ankle reconstruction with modified Broström procedure (4 cases), lateral closed-wedge calcaneal osteotomy (3 cases), percutaneous heel cord lengthening (19 cases), and gastrocnemius recession (1 case). In one patient with severe valgus deformity, staged total ankle arthroplasty was conducted after primary
1. The amount of orthopaedic surgery which is possible in patients with leprosy is immense. It is likely to decline with improved medical care as deformity rarely begins after the start of medical treatment. In spite of prolonged chemotherapy, skin smears often remain positive for more than five years and lifelong treatment may be necessary. 2. In Hong Kong the disease affects mainly those in the best working years of their lives and at an age when they should be best able to understand the benefits that treatment confers. Education of the public must be one of the main points of disease control. This education should extend to enable patients with anaesthetic extremities to learn the limitations that the disease places upon their activities. Thus they will be less liable to injure themselves and better able to prevent minor injuries from becoming serious. Ulceration only occurs in areas lacking protective sensation but, although bilateral anaesthesia is common, bilateral ulceration is not often seen. 3. In patients with diminished sensation or with paralysed muscle groups there is usually enlargement of the nerves but this may be difficult to detect. 4. Clawing of the fingers is best treated by standard surgical procedures but opposition transplant in the combined median and ulnar nerve paralysis of leprosy is less satisfactory. Any transplant must prevent hyperextension at the metacarpo-phalangeal joint and this is best done by providing a double insertion for the transplant. If the soft tissues between the first and second metacarpals are contracted it is better to perform osteotomy of the base of the first metacarpal bone rather than to perform the standard operation of soft-tissue release and skin grafting. 5. The value of tibialis posterior transplantation in drop-foot has been confirmed. 6. The problem of fitting an artificial limb to an anaesthetic stump has not been solved. It was often found that ulcers of the stump occurred even with well-fitting sockets and cooperative patients. If amputation above the foot is necessary it is usually wiser to try a through-knee amputation. 7. Return of power or sensation after the start of medical treatment is unusual but it is also unusual for these symptoms to be noted for the first time when the patient is taking sulphones. It would be worth while investigating the effects of decompression of the median nerve at the level of the wrist by dividing the carpal ligament in those patients developing symptoms and signs of impaired median nerve function. Nerve decompression should also be performed in patients showing tender, swollen nerves in acute lepromatous reactions where steroid therapy fails to bring improved function within six hours. 8. It is essential that surgical methods of limiting disability such as incision, decapsulation or transposition of nerves, which have received favourable comment in the past, should be repeated in a controlled series. Series, so far, have lacked reference to the natural history of the condition under medical treatment alone and have often lacked adequate follow-up. 9. Acute lepromatous reactions in the foot often subside with little bone destruction if the patient is rested in bed with the foot immobilised in plaster. If deformity occurs it may be corrected by
Purpose: Necrosis of the navicular bone, described by Müller then Weiss in 1927, is an uncommon finding, unlike talonavicular degeneration which is a rather frequent complication of talipes planovalgus. Between 1985 and 2000, we cared for 25 patients with this condition. The purpose of this retrospective analysis was to describe the clinical and radiological presentation and attempt to reconstruct its natural history with the aim of determining therapeutic indications. Material and methods: We analysed 25 cases of navicular bone necrosis observed in 14 women and 3 men (eight bilateral cases). Mean age of the patients was 39 years (range 16–59). The diagnosis of necrosis was established on the basis of structural alterations (densification, bone defects) and in the more advanced cases, flattening and “expulsion” of the navicular bone. We looked for clinical signs and described the radiological aspect of the necrotic zone. A computed tomography was available in 14 cases and magnetic resonance imaging in the five most recent cases. Results: Pain was the major sign in all cases. One-third of the cases occurred in a foot with prior planovalgus. History taking revealed elements suggestive of an aetiology in three cases: probable Köhler-Mouchet disease in a 16-year-old boy, sickle cell disease in a 35-year-old man, and prolonged walking with signs suggesting stress fracture in a 40-year-old woman. In the other 19 cases (11 women and 1 man, 7 bilateral cases), necrosis was considered idiopathic. Radiologically, we used the Ficat classification (described for hips): stage 0 with normal x-ray and strong uptake on scintigram (n=1), stage 1 with a normally shaped navicular bone but condensation or bone defect, stage 2 with modification of the shape of the bone without signs of degeneration, stage 3 where changes in the shape of the bone are associated with narrowing of the talonavicular then cuneonavicular space. Computed tomography included frontal and horizontal slices as well as lateral reconstructions indispensable to assess the posterior part of the interarticular spaces. Treatment was surgical in 12 cases and medical in 13. Well tolerated forms were treated with plantar ortheses with regular surveillance. Surgical procedures included
Introduction: This document is our report on the prospective follow-up of 38 patients operated between May 1998 and May 2005. If the technique in itself hardly poses any difficulty, our experience of talo-crural and sub-talar arthroscopy has proved to be a major asset. Materials and method: This involved 38 patients (23 men and 16 women) mean age 55y who received a double or
We present the treatment protocol of congenital clubfoot in different age groups that has been widely used in Bulovka Orthopedic Clinic since 1984. Conservative treatment begins immediately after delivery and corrects all presented deformities on the principle of subtalar derotation of the calcaneus. The correction is applied and an above-knee cast is changed every 48 hours. After five corrections and changes of casts, the casting and correction is then repeated weekly. After achieving reduction of deformities, the cast is changed at intervals of two to three weeks. Cast immobilisation should be continued for two to three months for postural clubfoot, and six to seven months for congenital clubfoot. After retention in the cast, a polypropylene above-knee splint is applied up to the age of two to three years. In addition, passive stretching exercise and stimulation of the lateral part of the foot should be provided in order to achieve muscle balance between the evertors and invertors. Surgical treatment: When conservative treatment is unsatisfactory, the goal of operative treatment is to reduce all deformities in a one-step procedure. Posterior capsulotomy at the age of three to six months is indicated when the forefoot has been corrected by conservative treatment but the hindfoot remains fixed in the equinus and mild varus, or at the age of six to 12 months for residual hindfoot equinus. Complete subtalar release according to McKay is required at the age of over six months to three years. Post-operative treatment is the same as for the abovementioned conservative treatment. Treatment between the age of three and seven: The choice of surgical procedure must be individual according to the deformity, but surgical correction of severe deformity principally includes extensive subtalar release, and lateral column shortening by cuboid enucleation. Treatment between the age of seven and ten: Individual procedures (Ilizarov method; Dwyer osteotomy of the calcaneus, or osteotomy of the mid-tarsal bones) are chosen to treat deformities. These procedures are usually combined with soft tissue release, but not with complete subtalar release. Treatment after the age of ten (skeletal maturity of the foot): The same methods as in the previous group are used. When severe or unsatisfactory results after previous surgical treatment are obvious, a
The results of further soft-tissue release of 79 feet in 60 children with recurrent idiopathic congenital talipes equinovarus were evaluated. The mean age of the children at the time of re-operation was 5.8 years (15 months to 14.5 years). Soft-tissue release was performed in all 79 feet and combined with distal calcaneal excision in 52 feet. The mean follow-up was 12 years (4 to 32). At the latest follow-up the result was excellent or good in 61 feet (77%) according to the Ghanem and Seringe scoring system. The results was considered as fair in 14 feet (18%), all of whom had functional problems and eight had anatomical abnormalities. Four feet (5%) were graded as poor on both functional and anatomical grounds. The results were independent of the age at which revision was undertaken.
