Results showed initial presentation, pathology and baseline patient-reported outcome scores differed between men and women with glenohumeral instability.

Justin A. Magnuson, BA, Carolyn M. Hettrich , MD, MPH, and colleagues analyzed prospective baseline data for sex-related differences among 1,010 patients (81.3% were men) with glenohumeral instability in the Multicenter Orthopaedic Outcomes Network (MOON) Shoulder Instability cohort using demographic characteristics, patient-reported outcomes, radiographic findings, intraoperative findings and surgical procedures performed. Researchers used the frequency, etiology, direction, severity classification system to categorize patients.

“A higher percentage of male patients experienced traumatic injuries and injury at sport, while hypermobility was identified in a higher percentage of female patients,” Magnuson told Healio.com/Orthopedics.

Results also showed significantly higher activity scores among men and significantly lower preoperative American Shoulder and Elbow Surgeons, Western Ontario Shoulder Instability Index, 36-Item health survey and single assessment numeric evaluation scores among women. Men and women had no significant differences in the number of dislocations. Researchers noted greater rates of labral pathology and bone loss intraoperatively in men and higher rates of capsular laxity among women, which resulted in more Latarjet procedures and more soft-tissue procedures for men and women, respectively.

“Similar to studies in the ACL and rotator cuff tear literature, females had lower baseline patient-reported outcome scores,” Magnuson said. “Future studies will evaluate whether these findings result in significant differences in outcomes.” – by Casey Tingle
