目的 分析铰链式外固定支架在急性复杂性肘关节骨折不稳中的应用价值。方法 选择2012年3月—2014年3月急性复杂性肘关节骨折不稳患者53例,采用单臂铰链式外固定支架固定,于术后1年进行肘关节功能评分(JOA),并根据X线片复查结果统计骨折愈合情况。结果 平均随访(16.5±5.0)个月,骨折愈合时间平均为(12.5±1.5)周,肘关节屈伸范围为113.34°±26.33°,前臂旋转范围为105.35°±26.23°。术后功能和活动度恢复较好,JOA总评分为84.02±19.13,有3例出现并发症,经对症处理好转。结论 应用铰链式外固定支架治疗急性复杂性肘关节骨折不稳定疗效较好,利于术后肘关节功能恢复。
Objective To analyze the clinical efficacy of hinged external fixator on acute complex elbow fracture and instability.Methods Fifty-three cases were selected from March 2012 to March 2014,who were diagnosed with acute complex elbow fracture and instability and underwent surgical therapies with single-armed hinged external fixators.They were then followed up after one year to evaluate Japanese Orthopaedic Assoiation (JOA) score and bone union based on radiological results.Results Average follow-up lasted for (16.5±5.0) months and average fracture healing took (12.5±1.5) weeks.The flexion and extension range of elbow joint was 113.34°±26.33° and the rotation range of forearm was 105.35°±26.23°.Post-operative function and range of motion were recovered as expected in general,with a total JOA score of 84.02±19.13.In addition,three cases were recovered from complications.Conclusion A high clinical efficacy is found of applying hinged external fixator to the treatment of acute complex elbow fracture and instability,which would be beneficial to the recovery of elbow joint function after surgical therapies.
