This study presented a pioneering investigation of the changes in the magnetic resonance imaging images of pectoralis major muscle (PMM) tendon rupture. In all, 26 men were evaluated with acute total PMM rupture (<3 months since injury) with a mean age of 37.3 years (SD = 9.7 years) and 10 control patients with a mean age of 32.6 years (SD = 4.2 years). The evaluation of the tendon PMM injuries was based on the magnetic resonance imaging exam and the histological analysis. The magnetic resonance imaging of the surgically showed two (7.1%) contralateral sides were normal, 16 (57.1%) showed superior tendinopathy, and 10 (35.7%) had total tendinopathy. Inferior tendinopathy was not observed. The tendon histology revealed degenerative changes in 16 (66.7%) fragments, with 12 (50.0%) considered as mild (<25%), and four considered as (16.7%) high (>50.0%) tendinopathy. Total acute rupture of the PMM tendon among weightlifters might be associated with tendinous degeneration prior to injury.
本研究对胸大肌（PMM）肌腱断裂的磁共振成像图像变化进行了开创性研究。共有26名男性接受了急性PMM完全断裂（受伤后<3个月）评估，平均年龄为37.3岁（标准差=9.7岁），另有10名对照患者，平均年龄为32.6岁（标准差=4.2岁）。对PMM肌腱损伤的评估基于磁共振成像检查和组织学分析。手术的磁共振成像显示，2个（7.1%）对侧正常，16个（57.1%）显示上肌腱病，10个（35.7%）有完全肌腱病。未观察到下肌腱病。肌腱组织学显示，16个（66.7%）碎片有退行性改变，其中12个（50.0%）被认为是轻度（<25%），4个（16.7%）被认为是高度（>50.0%）肌腱病。举重运动员中PMM肌腱的急性完全断裂可能与受伤前的肌腱退变有关。
