目的：观察比较带袢纽扣钢板和锁骨钩钢板治疗肩锁关节脱位的临床疗效。方法：选取2012年4月到2014年12月我院收治的肩锁关节脱位患者28例设为观察组，行袢纽扣钢板内固定，另选取2010年4月-2012年4月我院收治的肩锁关节脱位患者28例设为对照组，行锁骨钩钢板内固定治疗，术后比较两组手术时间、术中出血量、术后复位丢失量、肩关节功能恢复及影像学检查。结果：术后所有患者平均随访时间18.33±3.95个月，两组手术时间分别为（72.59±11.28）m i n、（65.39±7.13）m i n ,术中出血量分别为（154.39±20.88）ml、（136.35±31.28）ml。观察组复位丢失测定，术后1周喙锁距离为(23.98±4.05) mm，术后8个月为(24.73±5.47) mm，末次随访(25.39±5.22) mm，平均丢失(2.14±0.58) mm。肩关节功能恢复Karlsson 评估，优12例，良2例，差0例，优良率100%。对照组复位丢失测定，术后1周测量喙锁距离为(25.78±5.26)mm，术后8个月为(27.03±4.82) mm，末次随访为(29.11±3.47) mm，平均丢失(3.36±0.26) mm。肩关节功能恢复Karlsson 评估，优9例，良4例，差1例，优良率92.85%。结论：带袢纽扣钢板治疗肩锁关节脱位，在复位程度、术后复位丢失量、肩锁关节功能恢复、并发症发生情况均优于锁骨钩钢板治疗，临床效果显著。“,”Objective To observe and compare the clinical efficacy of EndoButton fixation system and clavicular hook-plate in the treatment of acromioclavicular dislocation.Methods Selection in April 2012 to December 2014, our hospital of 28 patients with acromioclavicular joint dislocation as observation group, line loops buttons steel plate internal fixation, the other selection in April 2010 - April 2012 our hospital of the acromioclavicular joint dislocation patients 28 cases as control group, the treatment of clavicular hook plate fixation, postoperative compared two groups of operation time, intraoperative blood loss, postoperative restoration loss amount, shoulder joint function restore and imaging examination.Results All patients postoperative follow-up was 18.33±3.95 months on average, two groups of operation time (72.59 ±11.28) min, respectively (65.39 ±7.13) min, intraoperative blood loss, respectively (154.39 ±20.88) for ml, ml (136.35±31.28). Observation group reset lost determination, postoperative 1 week beak lock distance (23.98± 4.05) mm, after eight months for (24.73 ±5.47) mm, the last follow-up (25.39 ± 5.22) mm, the average loss (2.14 ± 0.58) mm. Shoulder joint function restore Karlsson evaluation, optimal 12 cases, good in 2 cases, 0 cases, was 100%. Control reset lost determination, postoperative 1 week measures the distance to beak lock (25.78 ±5.26) mm, after eight months to (27.03 ±4.82 )mm, the last follow-up for (29.11±3.47 )mm, the average loss (3.36 ±0.26) mm. Karlsson assessment and recovery of shoulder joint function, which optimum 9 cases, 4 cases, and poor in 1 case, was 92.85%.Conclusions Compared with clavicular hook-plate, EndoButton fixation system hasobvious advantages in reduction degree, postoperative loss of reduction, functional recovery of acromioclavicular joint and complications for TossyⅢ acromioclavicular dislocation, and possesses significant clinical efficacy.
