目的:分析经腋窝入路拉力螺钉结合支撑钢板治疗IdebergⅡ型肩胛盂骨折的疗效。方法:对2016年1月至2021年6月采用经腋窝入路拉力螺钉结合支撑钢板治疗的26例IdebergⅡ型肩胛盂骨折患者进行回顾性分析,其中男15例,女11例;年龄21~75(43.12&...目的:分析经腋窝入路拉力螺钉结合支撑钢板治疗IdebergⅡ型肩胛盂骨折的疗效。方法:对2016年1月至2021年6月采用经腋窝入路拉力螺钉结合支撑钢板治疗的26例IdebergⅡ型肩胛盂骨折患者进行回顾性分析,其中男15例,女11例;年龄21~75(43.12±6.56)岁。采用Constant-Murley肩关节评分量表和加利福尼亚大学洛杉矶分校(University of California at Los Angeles,UCLA)评分对肩关节功能和临床疗效进行评估。结果:所有患者获得随访,时间19~42(30.6±10.5)个月。术后1年对患者进行Constant-Murley评分,结果由术前的28~47(34.9±2.5)分,升高为70~95(87.2±6.8)分;UCLA评分结果由术前的9~25(17.9±1.7)分,改善为29~35(33.1±2.3)分,其中优17例,良7例,可2例。两者评分结果与术前评分比较差异均有统计学意义(P<0.001)。患者术后均未出现感染和螺钉、钢板松动、断裂等并发症,2例在术后随访期有不同程度的肩部慢性疼痛。结论:经腋窝入路拉力螺钉结合支撑钢板治疗IdebergⅡ型肩胛盂骨折显露便捷,可直视下恢复肩胛盂正常解剖形态,利于选择适合螺钉及钢板放置的部位,达到较佳的治疗效果,并发症少,是一种有效、可靠的手术方法。展开更多
