【摘要】 目的 探讨闭合复位外固定架治疗伸直型桡骨远端骨折的疗效。方法 采用闭合复位外固定架治疗38例伸直型桡骨远端骨折患者。记录骨折愈合时间、并发症发生情况、影像学指标及Gartland-Werley评分。结果 患者均获得随访，时间3～7(4.17±1.06)个月。骨折均愈合，时间3～6个月。术后无针道感染、关节僵硬等并发症发生。尺偏角、掌倾角术后各时间点均大于术前(P<0.05);桡骨茎突高度术后1 d与术前比较差异有统计学意义(P<0.05),术后各时间点比较差异均无统计学意义(P>0.05);尺骨差异术后各时间点均优于术前(P<0.05),术后1、3个月与术后1 d比较差异均有统计学意义(P<0.05),术后3个月与术后1个月比较差异无统计学意义(P>0.05)。末次随访时，Gartland-Werley评分72～100分，优良率97.4%。结论 闭合复位外固定架治疗伸直型桡骨远端骨折疗效满意，能有效恢复尺偏角、掌倾角、桡骨茎突高度和尺骨差异，但注意有桡骨短缩导致尺骨相对长度增加而发生尺骨正向变异的风险。更多还原

【Abstract】 Objective To investigate the efficacy of closed reduction and external fixation in the treatment of extension-type distal radius fracture.Methods The 38 patients with extension-type distal radius fractures were treated with closed reduction and external fixation.The fracture healing time, occurrence of complications, radiographic indicators and Gartland-Werley score were recorded.Results All patients were followed up for 3-7(4.17±1.06) months.All the fractures healed within 3-6 months.There were no postoperative complications such as pin tract infection or joint stiffness.Ulnar inclination and palmar tilt: At various postoperative time points, both were higher than the preoperation(P<0.05).Radial styloid height: There was statistically significant difference between 1 d after operation and the preoperation(P<0.05),and there were no statistically significant differences at postoperative various time points(P>0.05).Ulnar variance: All postoperative time points were superior to the preoperative(P<0.05),there were statistically significant differences between postoperative 1 month, 3 months and 1 d after operation(P<0.05),and there was no statistically significant difference between postoperative 3 months and 1 month after operation(P>0.05).At the last follow-up, the Gartland-Werley scores were 72-100 points, with an excellent-good rate of 97.4%.Conclusions Closed reduction and external fixation provides satisfactory outcomes in the treatment of extension-type distal radius fracture, which can effectively restore the ulnar inclination, palmar tilt, radial styloid height, and ulnar variance.However, the attention should be paid to the risk of radial shortening leading to increased relative ulnar length and consequent positive ulnar variance.更多还原
