Results from this study showed a correlation between workers’ compensation claims and continued instability and patients with higher preoperative pain scores had lower SF-12 physical component scores postoperatively.
Researchers identified 38 patients who underwent the Latarjet procedure for anterior shoulder instability with glenoid bone loss. They collected data including demographics, patient satisfaction, VAS pain score, instability questions, Single Assessment Numeric Evaluation score, American Shoulder and Elbow Surgeons score, quick Disabilities of the Arm, Shoulder and Hand scores and SF-12 physical component scores. Coracoid size, conjoined tendon and subscapularis width, estimated glenoid defect surface area, Hills-Sachs interval and postoperative glenoid track engagement were also measured anatomically.
Twenty-five of the 38 patients underwent prior stabilization and six patients had workers’ compensation claims. Investigators noted mean subjective outcome scores had improved significantly. The high median pain satisfaction score was 9 out of 10. Due to continued instability, eight patients had failures.
According to researchers, there was a negative association between patients with either moderate or higher preoperative pain scores and postoperative SF-12 physical component scores. Researchers observed that postoperative instability was four times more likely to be experienced by patients with outside-and-engaged lesions or “off-track” lesions. Fifty percent of failures were due to off-track lesions compared with 16% without recurrent instability. Of the six patients with workers’ compensation claims, four had failed results. ‒ by Monica Jaramillo
