Background

Pectoralis major tendon rupture rate is increasing due to increased tendency to bodybuilding exercises, specially the bench press workout, and weight-lifting. The aim of this study was to determine the results of pectoralis major rupture repair with Achilles tendon allograft in bodybuilding athletes.

Methods

In this case series study, 22 bodybuilding athlete patients (24 pectoralis major ruptures) were undergone open surgical repair during January 2016 till December 2020. 21 ruptures were chronic (2 ruptures were revision) and 3 ruptures were acute. Surgical method was based on Achilles tendon allograft used to augment the ruptured site for lengthening the shortened tendon.The results were analyzed using Bak's criteria and Constant score in pre operation visit and 6th and 12th months and in the last follow up.

Results

All cases were male with the mean age of 32.1 ± 5.4. The mean duration time between injuries to surgery was 37 ± 46 month (1–182 months). Return to professional sport began at 10.9 ± 2.8 months after surgery in which 16 cases (66.7%) have returned to their pre surgery bench press workout records. No infection or hematoma occurred. At the final follow-up, Bak criteria demonstrated excellent, good and fair in 4, 18 and 2 shoulders respectively. The constant score increased from 87.9 ± 7.9 in pre operation visit to 92.7 ± 6.4 in the last follow up (P < 0.001).

Conclusions

It seems that our surgical method is an effective approach in cases with acute or chronic pectoralis major ruptures.

22 名健美运动员采用同种异体跟腱移植修复胸大肌断裂

背景

由于健美运动（特别是卧推锻炼和举重）的增加，胸大肌腱断裂率正在增加。本研究的目的是确定健美运动员用跟腱同种异体移植修复胸大肌断裂的结果。

方法

在本病例系列研究中，22 名健美运动员患者（24 例胸大肌破裂）在 2016 年 1 月至 2020 年 12 月期间接受了开放手术修复。其中 21 例为慢性破裂（2 例为翻修术），3 例为急性破裂。手术方法是采用跟腱同种异体移植来扩大断裂部位以延长缩短的肌腱。使用Bak标准和Constant评分对术前访视、第6个月和第12个月以及末次随访的结果进行分析。

结果

所有病例均为男性，平均年龄为 32.1 ± 5.4 岁。受伤到手术之间的平均持续时间为 37 ± 46 个月（1-182 个月）。术后10.9±2.8个月开始恢复职业运动，其中16例（66.7%）恢复到术前卧推锻炼记录。未发生感染或血肿。在最后的后续比赛中，巴克的标准分别在4肩、18肩和2肩上表现出优秀、良好和一般。恒定评分从术前访视时的87.9±7.9增加到末次随访时的92.7±6.4（P<0.001）。

结论

看来我们的手术方法对于急性或慢性胸大肌破裂来说是一种有效的方法。
