Magnetic Resonance Imaging of Symptomatic Swimmer’s Shoulder

OrthoArizona’s Kipling Sharpe, MD co-authored a research article for ScienceDirect titled: Magnetic Resonance Imaging of Symptomatic Swimmer’s Shoulder

Background: Several anterior labral lesions have been described but to our knowledge, they have not been described in the context of swimmer’s shoulder.

Hypothesis: We believe a plastically deformed anterior-inferior glenoid labrum is the pathognomonic lesion in swimmer’s shoulder. We believe that this can be seen but is often missed with MR arthrography.

Study design: Retrospective study.

Methods: Eleven detailed magnetic resonance imaging scans of symptomatic shoulders of swimmers who had arthroscopically demonstrated labral dysplasia were obtained between 2011 and 2014. One experienced musculoskeletal radiologist and one orthopedic surgeon interpreted each scan, specifically focusing on the anteroinferior labrum (from 3 to 6 o’clock).

Results: Nine of the eleven images (axial cuts) showed a more rounded/blunted appearance with undefined features at the anterior inferior labrum. Nine of nine images demonstrated an intact IGHL and labrum in the ABER position, three patients were unable to perform the positioning.

Conclusions: We believe the chronic repetitive micro-traumatic nature of competitive swimming leads to a more rounded/blunted appearance of the anterior inferior labrum on MR imaging. Further research may help identify these undefined features.
