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.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.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.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.

To study surgical strategies for ankle and foot deformities secondary to spina bifida and treatment methods for different types of deformities.From January 1990 and July 2009, 107 patients with ankle and foot deformities secondary to spina bifida were retrospectively analyzed. There were 44 males and 63 females, with an average age of 17.7 years (rangd from 1.3 to 52 years). Among the patients, 58 patients had double ankle deformities, 49 patients had unilateral deformities (22 cases on the left side, 27 cases on the right). Ninety-nine patients with equinus deformities were treated by achilles tendon lengthening and tendon transfering; 25 patients with talipes were treated by release of anterior tendon of ankle and tendon transfer; 17 patients with valgus and varus deformities were treated by tendon transfer and calcaneal osteotomy; 15 patients with flail deformities were managed treated by bone fusion between calcaneus and talus and shortening of achilles tendon; 9 patients with claw toe deformities were treated by bone fusion of interphalangeal joint or Ilizarovs distraction. AOFAS (American Orthopaedic FootAnkle Society) comprehensive scoring system was used to evaluate subjective pain and objective functional.Seventy-nine (127 feet) of 107 patients were followed up, and the duration ranged from 48 to 180 months (averaged, 64 months). According to AOFAS scoring system, the results were rated as excellent in 89 feet, good in 26 feet, moderate in 9 feet and poor in 3 feet.Treatment strategies for ankle-foot deformities mainly included four principles, deformity correction, muscular balance, joint stability and reservation of foot elasticity. Different combined procedure was applied for different foot deformities and received good therapeutic effects.

To study therapeutic effects of limited internal fixation combined with external fixation in the treatment of deformity of distal end of femur, as well as to explore its effect on the function of knee joint.From June 2004 to June 2009, 38 patients with deformity of distal end of femur were treated with osteotomy at femoral supracondylar and internalfixation combined with hybrid external fixator. Among the patients, 19 patients were male and 19 patients were female, ranging in age from 14 to 58 years, with an average of 26 years. Six patients had genu valgum, 4 patients had varus of the distal end of femur, 2 patients had varus combined with rotation deformity,3 patients had genu recurvation and 23 patients had deformity of genuflex. The function of knee joint was evaluated according to Dimeglio clinical assessment after the treatment.All the patients were followed up and the during ranged from 6 to 48 months, with a mean period of 23 months. All the deformity obtained satisfactory correction, without complications such as limitation of motion of the knee joint, under correction or over correction,displacement of the section of the osteotomy,internal fixation loosening and fracture. Nineteen patients got an excellent result, 12 good, 5 poor and 2 bad.Supracondylar femoral osteotomy and internal fixation combined with hybrid external fixator is a safe and effective surgery for the treatment of deformity of distal end of femur. This method combines the advantages of internal fixation and external fixation.

To study the methods and effects of Ilizarov distraction technique in treating the flexion deformity of the knee of arthrogryposis multiplex congenita.Between August 1998 and February 2003, 6 patients (10 knees) with the arthrogryposis multiplex congenita were treated, 4 patients in double knees, 5 males, 1 female, mean age 8 years and 2 months, ranged from 3 years and 7 months to 13 years. The preoperative flexion degree was averagely 51 degrees. The patients accompanied 13 other parts malformation of limbs. The modified Ilizarov distraction apparatus of the knee was used. While installing the apparatus in the operation, the knees should be kept in the of location of maximum extension, the center of joint hinges on the apparatus should be placed towards the rotatory center of the knee, two groups of 2 mm K-wires were passed through the femur and tibia around the knee, who were fixed on the proximal and distal rings. Distraction was started after the surgical procedure 5 days via rotating the threaded rods at the posterior of the knee, at an average of 2 to 3 mm per day, at the first week, after 2 weeks with the rate modified to 2 mm per day, up to the knee extended to 0 degrees. The accompanied deformities of the hip and/or the foot might be corrected at the same time or next time. The average duration of the distraction was 37 days (23-48 days). During the correction all limbs might undergo weight. After 2 weeks at the end of distraction the fixator was removed and the patients could walk by a long-leg brace.Ten knees with the flexion contracture were sufficiently corrected without severe complications. Nine knees of all were followed up at an average time of 1 years and 3 mouths, no recurrence of the deformity was seen in all patients, their function of walk was significantly improved.Ilizarov technique is a simply, safe and effective method for managing the flexion deformity of the knee of the arthrogryposis multiplex congentia. The procedure is conformable to the biological theories and microsurgical principles.
