[Treatment of equinovarus accompanied with ulcer using Ilizarov technology and limited operation].

OBJECTIVE: To explore the surgical method and clinical curative effect of Ilizarov technique combined with limited surgical treatment for neurotrophic malnutrition equinovarus accompanied with weight-bearing area ulcer. METHODS: From July 2004 to December 2011, 21 cases of neurological disorders equinovarus with skin ulcer in weight-bearing area were treated including 14 males and 7 females with an average age of 21.3 years old ranging from 8 to 32 years. Among them,19 cases with talipes equinovarus were on account of spina bifid and 2 cases on account of spinal cord injury of lumbar sacral segment. Nine cases were on the left foot and 12 cases were right foot. The ulcer area in out-below side of the fifth metatarsal bone was in 6 cases, in basement of the fifth metatarsal bone in 5 cases,in lateral of calcaneocuboid joint 2 cases, and in lateral of subtalar joint in 8 cases. Surgical procedure included plantar medial release technique, tendo-chilles lengthenning, and three-joint partial osteotomy. During operation,the skin and soft tissue of ulcer were resected and the incision was sutured when the ulcer was in the lateral of subtalar joint, and ankle Ilizarov external fixation for extension was installed after correcting talipes equinovarus partially. For the legacy skin ulcer in weight-bearing area,the Shenrg-ji cream (Chinese characters) was used after operation for one time per day until the wound healed. Adjusting Ilizarov external fixation for correcting residual deformity until it is satisfaction. During this process weight-bearing walking was keeping. RESULTS: All cases were followed up from 6 to 52 months with an average of 28 months. All ulcers were healing and no recurrence. The ulcer healing time was 14 to 36 days postoperative (26 days in average). Eighteen deformity feet were corrected satisfactorily, and recovered fully plantar foot, 3 feet appeared mild deformity after 1 year. Ankle joint activity appeared limited in 15 cases and got completely rigidity in 6 cases. The AOFAS increased from preoperative 34.0±7.2 to 86.0±8.5 postoperatively; 8 feet got excellent, 10 good,3 fair. CONCLUSION: The clinical effect of Ilizarov technique combined with limited operation and the Sheng-ji cream in correction of the talipes equinovarus with skin ulcer in weigh-bearing area on account of neurotrophic malnutrition is satisfactory, the surgical method is simple and the treating course in security, and serious complications can be avoided.
