Inferior functional outcomes seen in patients with abnormal subscapularis tendons

Patients who underwent subscapularis peel and had abnormal subscapularis tendons identified on ultrasonography experienced clinically significant inferior functional outcome scores, according to study results.

Researchers evaluated patients who underwent total shoulder arthroplasty with a minimum 1 year of follow-up by performing physical and ultrasound examinations and evaluating radiographs for osteotomy healing. Patients completed the WOOS index, Disability of the Arm, Shoulder, and Hand (DASH) and Constant Scores.

Patients with subscapularis tenotomy and lesser tuberosity osteotomy (LTO) were similar in age, hand dominance and sex but differed in follow-up duration.

Study results showed patients who underwent subscapularis peel (SP) demonstrated increased external rotation. However, the researchers found no significant differences in belly press and bear hug resistance, and no significant differences in WOOS, DASH and Constant Scores.

WOOS score difference became statistically significant after controlling for follow-up imbalance but was not considered clinically significant, according to the researchers.

When comparing ultrasonography assessment, four patients in the SP group had abnormal subscapularis tendons, whereas all tendons in the LTO group were normal.

Patients with abnormal ultrasound had significantly inferior WOOS and DASH scores, as well as significantly decreased belly pressed resistance, a lower trend in bear hug resistance and increased external rotation.
