To explore the proper methodology to treat cubitus varus deformity in adults with lateral closing wedge osteotomy.
The clinical data of 20 adult patients with post-traumatic cubitus varus deformity who underwent lateral closing wedge osteotomy and were followed up for 40 months on average were analyzed.
twenty-seven of the 28 patients showed excellent heal, and one case of delay in healing occurred. Eighteen elbow joints were in a neutral position, 6 were slightly varus, and 4 were varus. Tardy ulnar nerve palsy occurred in 5 cases. Reduction of elbow flexion was 11 degrees, even more than 20 degrees in 5 cases. Four patients were able to flex their elbows by 120 degrees or less. The reduction of extension was 3.4 degrees on average. Two patients showed failure of internal fixation, Kirshner wires were used in both of which.
Exact pre-operative planning of osteotomy, minimal injury to the soft tissues, proper dealing of the ulnar nerve, and stable internal fixation are the key factors that improve the function of elbow joint after the lateral closing wedge osteotomy and reduce the post-operative complications.
探讨采用外侧闭合楔形截骨术治疗成人肘内翻畸形的合适方法。
分析20例接受外侧闭合楔形截骨术且平均随访40个月的创伤后肘内翻畸形成年患者的临床资料。
28例患者中27例愈合良好，1例出现延迟愈合。18个肘关节处于中立位，6个轻度内翻，4个内翻。5例出现迟发性尺神经麻痹。肘关节屈曲度减少11度，5例超过20度。4例患者肘关节屈曲不能达到120度或更小。伸直度平均减少3.4度。2例出现内固定失败，均使用了克氏针。
精确的术前截骨规划、对软组织的最小损伤、正确处理尺神经以及稳定的内固定是改善外侧闭合楔形截骨术后肘关节功能并减少术后并发症的关键因素。
