Key result
Weightlifting, particularly the clean-and-jerk maneuver, causes specific MRI patterns of shoulder injuries along the line of vector force, including acromioclavicular joint sprains and rotator cuff tears.
Why the study?
Weightlifting can cause various shoulder pathologies with specific MRI patterns, requiring familiarization among radiologists and sports medicine physicians to help prevent further injury.
This pictorial essay reviews MRI patterns of shoulder injuries in strength trainers to aid radiologists and sports medicine physicians in diagnosis and training modification.
MRI patterns of weightlifting-related shoulder injuries illustrated; hypothesis-generating and needs prospective validation before guiding practice.
Weightlifting, a recent addition to strength training regimes of elite athletes, offers various benefits such as increased muscle/tendon/bone strength, bone density, metabolism, and cardiac function. Although beneficial, weightlifting can contribute to various shoulder pathologies that include rotator cuff impingement and injuries to tendons/muscles/bones of the shoulder and shoulder girdle, with specific patterns of injury identified on magnetic resonance imaging (MRI). Our pictorial essay, therefore, aims to familiarize radiologists and sports medicine physicians with the mechanisms, various types, and MRI patterns of shoulder/shoulder-girdle injuries, thereby enabling appropriate alterations to training regimens to prevent further injury.

Ariyanayagam et al. (2023) conducted a review in Shoulder injuries. Weightlifting was evaluated. Weightlifting, particularly the clean-and-jerk maneuver, causes specific MRI patterns of shoulder injuries along the line of vector force, including acromioclavicular joint sprains and rotator cuff tears.
