Introduction. Taylor Spatial Frame (TSF) has been designed to treat complex tibial, foot and ankle deformities using computer software. We have performed various osteotomies in combination with different soft tissue procedures, with the use of TSF. Material and Methods. A retrospective study of 20 consecutive patients operated by, senior author SSM, from 2004 onwards who underwent surgical correction of tibia, ankle, midfoot and hind foot including lateral column lengthening, calcaneal and midfoot osteotomies. Demographic details, diagnosis, procedures (including previous operations), length of follow-up, outcome and complications were recorded. Of the 20 patients, 13 were men and 7 women. The mean age was 39 years (range 18 to 70). 5 patients had TSF for malunion or non-union of ankle fractures, malunion of tibia (5), congenital talipes equino-varus(3), acute fracture of ankle (2), one patient each for spina bifida, Poliomyelitis, Charcot-Marie-Tooth disease, equino-varus due to periventricular leuco-encephalopathy and avascular necrosis of the talus. Bilateral TSF for torsional malalignment of tibia (1). Results. Follow up 6 to 54 months (mean 19.4). Patient based foot and ankle outcome criteria were used. Of the 20 patients, 16 had no pain and satisfactory range of movement and function at the last follow up. Post-operative complications included pin site infection(2) and frame hardware malfunction (2)patients, residual deformity requiring surgical correction at 22 months, (1) delayed union, neuropathic pain in (1), residual equinus deformity requiring Botox injections(1) and osteomyelitis requiring debridement(1). Conclusion. We present this series of complex congenital and acquired conditions of the foot and ankle treated with corrective osteotomies and Taylor Spatial Frame with good results

Introduction. Ankle fusion presents a difficult problem in the presence of infection, inadequate soft tissue, poor bone stock and deformity. Nonunion and infection remains a problem even with internal fixation. Ilizarov frame provides an elegant solution to the problem with stable remote fixation while allowing lengthening, deformity correction and weight bearing. Patients and methods. Twenty-one consecutive patients were studied. The mean age at onset of disease was 52 years (range 4-70). Mean duration of the problem was 59.9 months (6-372). Aetiology included traumatic arthritis in 5, traumatic arthritis with osteomyelitis in 1, failed ankle fusion in 8, septic arthritis in 1, infected ankle fracture nonunion in 1, avascular necrosis of talus in 1, congenital deformity in 3 and failed ankle arthroplasty in 1. 15 patients had deformity of the ankle at the time of presentation. 15 of the 21 patients had either clinical or radiological evidence of infection. Treatment principles involved local excision, deformity correction with good alignment and soft tissue management. Static Compression was achieved with an Ilizarov frame while dynamic fixation was performed in 3 cases for lengthening. Antibiotics treatment was continued until union in the infected cases. On achieving union the frame was removed and a below knee cast was applied for 4 weeks. Results. Fusion was achieved in all cases at an average time of 5 months. One patient had below knee amputation for chronic pain. There was no recurrence of infection. Complications included pin site infection, lateral impingement, drug reaction and hind-foot pain. The results were assessed in terms of SF36 and Modified foot and ankle score. Conclusion. The Ilizarov ankle fusion is a reliable salvage procedure in difficult ankle problems
