目的：比较桥接组合式内固定手术与锁定加压钢板内固定术治疗四肢骨折的效果。方法：选取2015年1月~2016年7月我院收治的四肢骨折患者70例为研究对象，随机分为观察组、对照组各35例，分别实施桥接组合式内固定术、锁定加压钢板内固定术，术后随访6个月，比较两组手术一般资料，应用Constant肩关节评分、Hss膝关节评分、疼痛视觉模拟评分（VAS）评价两组肩肘关节功能及疼痛度，采用健康调查简表（SF-36）分析其生活质量，并观察术后并发症。结果：观察组手术时间、骨折愈合时间较对照组短，术中出血量低于对照组；术后两组Constant评分、Hss评分均较同组术前明显增加，但组间对比差异无统计学意义，观察组手术后VAS评分（2.17±0.25）分低于对照组；观察组术后6个月SF-36生理方面、心理方面评分及总评分（88.34±1.67）分均明显高于对照组；观察组术后6个月随访期间，并发症发生率5.71%较对照组22.86%低。结论：桥接组合式内固定手术与锁定钢板内固定术相比，治疗四肢骨折疗效较好，可明显缩短手术时间、骨折愈合时间，术中出血量较少，术后并发症发生率低，患者生活质量明显提高，值得在临床推广应用。

Objective To compare the effects of bridge combined internal fixation and locking compression plate fixation in the treatment of limb fractures. Methods A total of 70 patients with limb fractures were selected from January 2015 to July 2016 in our Hospital. The patients were randomly divided into the observation group and the control group with 35 cases in each group: The observation group was treated with bridging combined internal fixation and the control group was given locking compression plate internal fixation. After 6 months of follow-up, the general operation data between the two groups were compared and the Constant shoulder score, and Hss knee score, visual analogue scale (VAS) were used to assess application of the function and pain degree of shoulder and elbow joint between the two groups. And the quality of life was analyzed by the short form health survey (SF-36) and the postoperative complications were observed. Results The operative time and fracture healing time were shorter in the observation group than those in the control group. The Constant score and the Hss score of the two groups after operation were increased significantly compared with the preoperative group, but there was no significant difference between the two groups. The VAS score (2.17±0.25) in the observation group was significantly higher than that in the control group. The physiological and psychological scores and total score (88.34±1.67) of SF-36 in the 6 months after the operation were significantly higher in the observation group than those in the control group. The incidence rate of complications was 5.71% in the observation group at 6 months follow-up, which was lower than that in the control group with 22.86%. Conclusion Compared with locking compression plate internal fixation, bridging combined with internal fixation is better for the treatment of limb fractures and can significantly shorten the operation time, fracture healing time, and produce less intraoperative blood loss, low postoperative complications rate, and significantly improve patients quality of life, therefore it is worth clinical application.
