Hypothesis: This study presented a pioneering investigation of the changes in the MRI images of PMM tendon rupture compared with the contralateral side among weightlifters and histologically analyzed ruptured PMM tendons to determine the presence of changes. Methods: 36 men were evaluated, 26 with acute total PMM rupture (<3 months since injury) with a mean age of 37.3 years (SD=9.7 years) and ten control patients with a mean age of 32.6 years (SD=4.2 years). All cases were caused by the bench press exercise. The patients were evaluated preoperatively using a Siemens 1.5 Tesla Magnetic Resonance Imaging (MRI) machine. On the contralateral side to the PMM injury, chest MRI images were obtained to evaluate possible PMM tendinopathy. The evaluation of the tendon PMM injuries was based on the MRI exam, the histological analysis performed in this study. Results: MRI of the surgically treated patients in the case group, 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. Histology Two fragments could not be analyzed for insufficient tissue. The tendinopathy evaluations of the tendon fragments 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. Conclusion: Total acute rupture of the PMM tendon among weightlifters might be associated with changes in the MRI signal and tendinous degeneration prior to injury, especially following bench press exercise, which is historically associated with the use of anabolic steroids.
