Objective To discuss the clinical effects and the influence of external fixator combined with Kirschner wires internal fixation on the recovery of wrist function in patients with distal radius fracture. Methods A to-tal of 132 patients with distal radius fracture, who admitted to Orthopaedic Trauma Center of the 153rd Center Hospital of Chinese PLA during August 2012 to July 2015, were selected and divided into the observation group (n=66) and the con-trol group (n=66) according to random number table. The observation group was treated with external fixator combined with Kirschner wires, and the control group was treated with manipulative reduction and splint fixation. Then the clinical manifestations and wrist function recovery condition were contrasted between the two groups 12 weeks after the opera-tion. Results There was no significant difference in the palmar tilt (4.61 ± 1.32)° vs (4.57 ± 1.40)° and ulnar deviation (15.22±2.81)° vs (15.28±2.82)° between the two groups before the treatment (P>0.05), and which significantly increased after the treatment (P<0.01). There was also no significantly difference after the treatment between the two groups:the palmar tilt of (7.99±1.34)° vs (7.93±1.38)° and ulnar deviation of (19.26±2.83)° vs (19.25±2.81)°, P>0.05. The swellingtime of back of hand, pain relief time, fracture healing time in the observation group were (6.2±1.9) d, (3.1±0.5) d, (34.2± 8.1) d, respectively, which were significantly shorter than corresponding (9.7±2.2) d, (4.8±0.6) d, (45.4±8.3) d in the con-trol group (P<0.01). After the treatment, the excellent rate of the wrist function in the observation was 87.9％, which was significantly higher than 69.7％in the control group (P<0.05). Conclusion External fixator combined with Kirschner wires internal fixation has the advantages of reliable fixation, faster postoperative recovery, ideal wrist joint function in the treatment of patients with distal radius fracture, which is worthy of promotion.%目的 探讨外固定支架与克氏针联合用于桡骨远端骨折对患者腕关节功能的影响.方法 选择2012年8月至2015年7月期间解放军第153中心医院全军创伤骨科中心收治的132例桡骨远端骨折患者以随机数表法分为观察组与对照组,每组66例,观察组给予外固定支架结合克氏针治疗,对照组给予手法复位小夹板固定治疗,术后12周比较两组患者治疗前后的临床表现和腕关节功能恢复情况.结果 观察组和对照组患者治疗前的掌倾角[(4.61±1.32)°vs(4.57±1.40)°]、尺偏角[(15.22±2.81)°vs(15.28±2.82)°]比较差异均无统计学意义(P>0.05);治疗后,观察组和对照组患者的掌倾角[(7.99±1.34)°vs(7.93±1.38)°]、尺偏角[(19.26±2.83)°vs(19.25±2.81)°]均显著增加,且与组内治疗前比较差异均具有显著统计学意义(P<0.01),但治疗后两组患者的掌倾角、尺偏角比较差异均无统计学意义(P>0.05);观察组患者的手背消肿时间、疼痛环节时间及骨折愈合时间分别为(6.2±1.9)d、(3.1±0.5)d、(34.2±8.1)d,均显著短于对照组的(9.7±2.2)d、(4.8±0.6)d、(45.4±8.3)d,差异均具有显著统计学意义(P<0.01);观察组患者腕关节功能优良率为87.9％,明显高于对照组的69.7％,差异具有统计学意义(P<0.05).结论 外固定支架结合克氏针用于桡骨远端骨折的治疗,复位固定可靠,术后恢复快,腕关节功能恢复理想,值得推广.
