Introduction. Charcot Arthropathy related foot and ankle deformities are a serious challenge. Surgical treatment of these deformities is now well established. The traditional surgical method of extensive surgical exposure, excision of bone, acute correction and internal fixation is not always appropriate in presence of active ulceration, deep infection and poor bone quality. Minimally invasive osteotomies and gradual correction of deformities with a circular frame are proving helpful in minimizing complications. We present our experience with the use of Taylor Spatial Frame (TSF) in 10 patients with recurrent ulceration and deformity. Materials and Methods. Our indication for the treatment with TSF is recurrent or intractable ulceration with or without active bone infection or a history of infection in a deformed foot and/or ankle. There are 2 female and 8 male patients in this cohort. We used a long bone module for ankle and hindfoot deformities (3 patients) and a forefoot 6×6 butt frame (7 patients) for midfoot deformities. An osteotomy through midfoot was performed in all chronic stable midfoot deformity cases and a calcaneal osteotomy and gradual correction through ankle in when hindfoot and ankle deformities co-existed. Results. Our outcome measures are a complete healing of ulcer and infection without recurrence, clinically plantigrade foot and ability to wear regular shoes or diabetic footwear. We achieved this outcome in 9 out of 10 patients. Successful patients remain ulcer free at minimum 7 and maximum 14 years follow up. Complications included eight episodes of pin infection that responded to oral antibiotics only and two pin breakages. Conclusions. Our results confirm that Taylor Spatial Frame treatment is a good alternative to traditional surgery in high-risk complex Charcot neuroarthropathy foot and ankle deformities

Aims

As an alternative to external fixators, intramedullary lengthening nails (ILNs) can be employed for distraction osteogenesis. While previous studies have demonstrated that typical complications of external devices, such as soft-tissue tethering, and pin site infection can be avoided with ILNs, there is a lack of studies that exclusively investigated tibial distraction osteogenesis with motorized ILNs inserted via an antegrade approach.

Introduction. Review of the literature indicates variable results for ankle arthrodesis with many complications. With improved prothesis and technique for total ankle arthroplasty and an increase in severe ankle deformities such as Charcot's joint and the neuropathic diabetic foot we are faced with the need to decrease the variables in ankle arthrodesis in primary and salvage arthrodesis. We will review current methods for ankle arthrodesis and critic how they deal with primary and revision ankle arthrodesis surgery. Materials and methods. A customised plate or modified synthes proximal tibial plate and technique for salvage of complex pathology utilising a anterior approach and application of a contoured ustomised plate with co-axial screw fixation. Anterior incision was performed with removal of the lateral malleolus, for bone grafting in revision cases only. Thirteen arthrodeses were performed; four of these were pan-talar. All patients underwent objective and subjective assessments including overall patient satisfaction. The American Orthopaedic Foot and Ankle Society ankle/hind foot scoring system was used. The aim of this study is to identify the time taken to achieve radiologic arthrodesis, complications encountered, the required post-operative recovery for arthrodesis to be achieved and the overall patient satisfaction of results in the early to midterm post-operative period have been followed up for three years. Conclusion. The technique offers considerable flexibility allowing the calcaneus to be incorporated in the proposed arthrodesis where necessary. With multiple points for fixation and coaxial screw entry points the contoured customised plate provides a rigid fixation for arthrodesis stabilisation with added compression being the major advantage of this technique

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

Background. Total ankle arthrpoplasty (TAA) was performed frequently for ankle deformity caused by rheumatoid arthritis (RA) and osteoarthritis (OA). TAA has some advantages over ankle arthrodesis in range of motion (ROM). However, loosening and sinking of implant have been reported with several prostheses, especially constrained designs. Recently, we have performed mobile bearing TAA and report short term results of this prosthesis followed average 3 years. Method. 20 total ankle prostheses were implanted in patients with RA (n=14) or OA (n=6) in 19 patients (5 male and 14 female, one bilateral), between 2005 and 2009. We used FINE total ankle arthroplasty that is mobile bearing system (Nakashima Medical Co., Ltd, Okayama, Japan). All patients were assessed for American Orthopaedic Foot and Ankle Society (AOFAS) score, ROM in plantar flexion and dorsiflexion at the point of pre-operation and final follow-up. We evaluated radiolucent line, sinking, and alignment of prostheses at final follow-up. Results. At the operation, patients were, on average, 64.1 years old. The mean follow-up period was 34.0 (6∼55) months. We found excellent satisfaction and a significant improvement of AOFAS score. Plantar flexion and dorsiflexion also improved compared with the preoperative state, but not significantly (table 1). At final follow-up, five ankles (25%) showed radiolucent line around the components or sinking of prostheses. Three ankles (15%) was performed reoperation, due to early infection, progressive medial OA change by sinking, and loosening of the talus component. Discussion. Radiolucent line around the components or sinking of prostheses occurred at high frequency (25%). But, only two ankles (10%) were had to reoperation, cause by pain. We take account of the fact that the symptom was lack in spite of radiological changes. Good clinical results can be achieved with FINE total ankle arthroplasty system. However, this series was short term of follow-up. We need to evaluate mid- and long- clinical results. Mobile bearing total ankle arthroplasty is a treatment option for RA and OA
