Analysis of the vacuum sealing drainage technique combined with sural neurovascular pedicle fascio-cutaneous flap to repair deep wounds in the foot near the ankle joint with exposed bone and tendons / 中国骨伤

<p><b>OBJECTIVE</b>To evaluate the practical method of vacuum sealing drainage (VSD) technique combined with sural neurovascular pedicle fasciocutaneous flap to repair deep wounds in the foot near the ankle joint with exposed bone and tendons.</p><p><b>METHODS</b>From January 2006 to January 2009, 79 patients with deep wounds in the foot near the ankle joint with exposed bone and tendons were treated by VSD technique combined with sural neurovascular pedicle fasciocutaneous flap including 58 males and 21 females with an average age of 34 years old ranging from 7 to 59 years. There were 17 cases in low 1/3 part of leg and achilles tendon, 28 in lateral malleolus and lateral dorsum of foot, 21 in medial malleolus and medial dorsum of foot, 13 in heel and pelma. Firstly the wounds were debrided and cultivated by using VSD technique, then the soft tissue defections were repaired with sural neurovascular pedicle fasciocutaneous flap.</p><p><b>RESULTS</b>The area of flap was from 6 cm x 5 cm to 18 cm x 15 cm; All patients stayed in hospital for 14 to 30 days, 18 days in average. Living flaps of all patients were followed-up from 6 months to 3 years, the flaps of 2 patients were mostly necrotic, 3 were necrotic, 5 cases appeared obstacle of venous back streaming. The others survived with no infections.</p><p><b>CONCLUSION</b>The wound would become fresh and clean as soon as possible with VSD. The sural neurovascular pedicle fasciocutaneous flap could provide a good covering for the exposed wound. Therefore the wound healed faster with friction resistance and fine appearance. The time of hospitalization were greatly shortened after combined application.</p>

Trephine arthrodesis of subtalar joints: operative technique and clinical effect / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To review the operative technique of trephine arthrodesis of subtalar joints and evaluate its clinical effect.</p><p><b>METHODS</b>From June 1998 to October 2006, we performed subtalar arthrodesis on 38 feet of 34 patients for a variety of painful disorders of hindfoot with trephine technique. Clinical and radiologic follow-up evaluations were performed for 45 months on average (range, 21 to 110 months) after arthrodesis.</p><p><b>RESULTS</b>No severe complications were found in this study except one patient with dropfoot and two with skin necrosis. The average ankle-hindfoot scores of the American Orthopaedic Foot and Ankle Society (AOFAS) was improved from 48.3 preoperatively to 79.2 postoperatively (P<0.05). The pain scores of visual analogue scales (VAS) decreased from 7.2 (range, 3 to 10) preoperatively to 2.6 (range, 1 to 6) postoperatively (P<0.05). Subjectively, the patients experienced improvements in pain, function, cosmesis, and shoewearing. Overall, 30 patients were satisfied and all patients would have this procedure again under similar circumstances. Postoperative radiology showed that complete union was found in 35 feet 6 months after operation, with the successful union rate of 92.1%. There was an increase in arthritic scores for 5 ankles, 4 talonavicular joints, 4 calcaneocuboid joints, and 4 midfoot joints. Nonunion occurred in 3 subtalar joints with anterolateral approach, which required revision arthrodesis.</p><p><b>CONCLUSION</b>Isolated subtalar arthrodesis with trephine method is an effective procedure for painful malalignment of hindfoot.</p>

Emergency medial malleolus osteotomy for the treatment of fractures of talar neck combined with dislocation of talar body / 中国骨伤

<p><b>OBJECTIVE</b>To explore therapeutic effects of emergency medial malleolus osteotomy for the treatment of fractures of talar neck and dislocation of talar body.</p><p><b>METHODS</b>From 1995. 6 to 2007. 10, among 24 patients with fractures of talar neck and dislocation of talar body, 18 patients were male and 6 patients were female, ranging in age from 28 to 58 years (mean 35.4 years). The duration from injury to the emergency ward ranged from 0.5 to 12 h. All the patients were treated in 5 hours after hospitalization with emergency medial malleolus osteotomy and internal fixation. Firstly, osteotomy was made above the medial malleolus tip; Secondly, the medial malleolus was turned over downward to uncover the talus; Then, the fracture of talus can be reduced in direct visidn.</p><p><b>RESULTS</b>All the patients were followed up ranged from 6 to 60 months. According to Kenwright evaluation standards, 18 patients obtained an excellent results, 4 good and 2 fair.</p><p><b>CONCLUSION</b>It is easy and clearly to perform medial malleolus osteotomy. The blood circulation of talus is preserved. So it is an effective method to treat the fractures of talar neck and dislocation of talar body.</p>
