摘　　要：目的:对比肋骨骨折患者采用精准定位下记忆合金环抱器内固定治疗与保守治疗的疗效。方法:回顾性分析60例多发性肋骨骨折患者资料,30例患者采用精准定位下记忆合金环抱器内固定治疗(试验组),30例患者采用胸带固定保守治疗(对照组),比较两组患者的疗效及并发症情况。结果:试验组患者下床时间、住院时间、VAS疼痛评分分别为(1.20±0.41)d、(6.53±1.11)d和2.57±1.65,对照组分别为(2.30±1.09)d、(10.47±3.63)d和4.37±1.25,试验组显著优于对照组(P<0.01)。试验组迟发性血气胸的发生率显著低于对照组(P<0.01)。治疗后肺不张、肺部感染、胸廓畸形的发生率两组之间无统计学差异(P>0.05)。患者均获随访,精准定位下记忆合金环抱器内固定患者,肋骨均未出现二次移位。结论:精准定位下记忆合金环抱器内固定治疗效果明显优于保守治疗,具有准确、安全、操作简便、微创等优点,是治疗多发性肋骨骨折的一种理想方法。Objective To compare the therapeutic effect of the internal fixation of memory alloy embracing fixator in precise positioning and traditional non-operative therapy for the treatment of rib fracture. Methods The clinical data of 60 patients with rib fracture were analyzed retrospectively. Operation group included 30 patients treated with internal fixation of memory alloy embracing fixator in precise positioning, while control group included 30 patients treated with traditional non-operative therapy.The therapeutic effect and complications were compared between two groups. Results The bed time, hospital stay, visual analogue scale（VAS） score in operation group were（1.20±0.41） d,（6.53±1.11） d, and 2.57±1.65, respectively, significantly better than（2.30±1.09） d,（10.47±3.63） d, and 4.37±1.25 in control group（P〈0.01）. The incidence of delayed hemopneumothorax in operation group was lower than that in control group（P〈0.01）, but no statistical differences were found in the incident of atelectasis, lung infection,and chest deformity after treatment（P〉0.05）. The follow-up showed that patients treated with the internal fixation of memory alloy embracing fixator in precise positioning didn’t had rib displacement again. Conclusion The internal fixation of memory alloy embracing fixator in precise positioning is an ideal treatment for multiple rib fractures for it achieves a better therapeutic effect than traditional treatment and has the advantages of safety, easy operation and less surgical trauma.
