HOLLYWOOD, Fla. — Adolescent athletes had no identifiable risk factors for recurring shoulder instability following an initial stabilization procedure, according to data presented at the Arthroscopy Association of North America Annual Meeting, here.

“While results of revision surgery have been published in adult patients, the results of revision in adolescents [were previously] unknown,” Andrew J. Blackman, MD, said.

Blackman and colleagues conducted a retrospective study of 90 athletes who were younger than 18 years and underwent primary anterior shoulder stabilization for recurrent instability. Average follow-up was 5.5 years. Failure rates after any revision surgery were assessed using Kaplan-Meier analysis while outcomes were assessed using Marx Activity Score, American Shoulder and Elbow Surgeons (ASES) Score, UCLA Shoulder Rating score, and Rowe Instability score at 2-year follow-up (Marx and ASES) or at last follow-up (UCLA and Rowe). They also evaluated humeral or glenoid bone loss as well as demographic data.

Overall, 15 patients underwent revision surgery, nine of which had recurrent dislocations while five patients required a repeat revision stabilization at a mean of 50 months after initial revision. Kaplan-Meier reoperation-free estimates were 85.7% and 77.9% at 24 and 48 months, respectively, after revision. Average final scores were 14.8 for upper extremity Marx activity, 82.1 for ASES, 68.1 for Rowe instability, and 30.8 for UCLA. Blackman said there were no differences between patients who required revision surgery and those who did not in terms of demographics, postoperative outcomes or preoperative or perioperative characteristics. —by Christian Ingram
