  • A PROBE TO THE TREATMENT OF MADELUNG DEFORMITY

    Objective To explore a method of treating Madelung deformity. Methods Seven cases of Madelung deformity had been treated with the excision of ulnar carpi ulnaris segment and distal osteotomyof radius and tight constrict of extensor carpi ulnaris from Mar. 2000 to Nov. 2003. The angle of ulnar tilting was 37-70° and the angle of volar tilting wasover 16°. A longitudinal incision on each side of the radius and ulnar was made, the ulna was excised about 2-3 cm segment. Then the fracture of ulna was fixed by double across vertical steel wire and the radius was fixed with medullarywire. Lastly the extensor carpi ulnaris was shortened and sutured after the wrist was located restposition. Results After surgery, the deformity of wrist was improved and pain-free in the seven cases. The angle of ulnar tilting was reduced to 22-24°. The angle of volar tilting was reduced to 15° below. Follow-ups were conducted inthe 7 patients for 2 years in average. The activity of wrist joint and the rotation of forearm recovered from those before operation. The wrist joint could stretch fully. Conclusion This method of treating Madelung proves to be effective inrecovering deformity, releasing pain, improving function, and reducing traumatic osteoarthritics of the distal radioulnar joint. 

  • 小腿远端皮支链血管皮瓣修复足踝部缺损的疗效观察

    目的 总结小腿远端皮支链血管皮瓣修复足踝部软组织缺损的疗效。 方法2008年5月-2011年10月,收治11例足踝部软组织缺损患者。男9例,女2例;年龄20~70岁,平均46.5岁。其中外伤致软组织缺损8例,伤后至手术时间2 h~21 d;恶性肿瘤切除后缺损3例。缺损范围为4 cm × 4 cm~7 cm × 7 cm;创面伴骨、肌腱外露。采用大小为4.5 cm × 4.5 cm~9.0 cm × 9.0 cm的小腿皮支链血管皮瓣修复缺损。供区直接拉拢缝合或游离植皮修复。 结果1例皮瓣术后发生远端皮缘坏死,经换药后二期修整缝合愈合;其余皮瓣均顺利成活,创面均Ⅰ期愈合。供区植皮均成活;切口Ⅰ期愈合10例,Ⅱ期愈合1例。术后患者均获随访,随访时间6~12个月,平均8个月。皮瓣外形不臃肿,色泽、质地优良,耐磨无破溃,穿鞋行走自如。 结论小腿远端皮支链血管皮瓣不牺牲主要血管及皮神经,手术操作简便,术后成活率高,外观较好,是修复足踝部软组织缺损的理想方法之一。

  • POSTEROLATERAL AND POSTEROMEDIAL APPROACHES FOR TREATMENT OF POSTERIOR Pilon FRACTURES IN ELDERLY PATIENTS

    ObjectiveTo explore the clinical outcomes of open reduction and internal fixation by posterolateral and posteromedial approaches for treating posterior Pilon fractures in elderly patients. MethodsBetween August 2009 and August 2014, 20 elderly patients with posterior Pilon fractures were treated with open reduction and internal fixation by posterolateral and posteromedial approaches. There were 14 males and 6 females, aged from 66 to 83 years (mean, 72.7 years). The causes were falling injury in 11 cases and traffic accident injury in 9 cases. All the patients had lateral malleolus and medial malleolus fractures. The time from injury to operation was 7-14 days (mean, 8.6 days). The posterolateral incision was made to expose the posterolateral bone fragments of posterior malleolus and lateral malleolus fracture, and the posteromedial incision was made to expose the posteromedial fracture fragments of posterior malleolus and medial malleolus fracture. After reduction, fracture was fixed with locking plate or cannulated screw. All the patients began to functional exercise at 1 day after operation. ResultsThe operation time was 60-110 minutes (mean, 92 minutes). The incisions healed primarily in all patients. There were no complications of incision dehiscence, infection, implant exposure, and nerve damage. No irritation sign of tendon was observed. All 20 cases were followed up for 12-18 months (mean, 13 months). The X-ray films showed that fracture healed at 3-9 months, with an average of 5.2 months. During follow-up period, no loosening or breakage of the implant was observed. The other patients could walk normally except 2 patients (over 80 years old) who could walk with crutch. According to American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, the results were excellent in 12 cases, good in 4 cases, and fair in 4 cases; the excellent and good rate was 80%. ConclusionA combination of posterolateral approach and posteromedial approach for open reduction and fixation of posterior Pilon fractures can achieve satisfactory effect in elderly patients. It has the advantages of protecting ankle blood supply and avoiding the soft tissue necrosis and implants exposure.
