BOSTON — A prospective, randomized controlled trial presented at the American Shoulder and Elbow Surgeons Annual Meeting showed patients who underwent shoulder arthroplasty through either the standard or subscapular-sparing technique had no statistically significant differences at 2-year follow-up.
Young W. Kwon, MD, and colleagues randomly assigned 107 patients with end-stage shoulder osteoarthritis (OA) to undergo shoulder arthroplasty through either the standard technique or the subscapular-sparing technique. Of the patients who were excluded, nine were assigned to undergo the subscapular-sparing technique but were converted to the standard technique due to insufficient exposure during surgery, according to Kwon.
“Both groups of patients saw significant differences in their pain,” Kwon said in his presentation. “However, the differences between the two groups over time was not statistically different.”
He also noted both groups had improvements with American Society of Anesthesiologist functional outcome scores, but there were no statistically significant differences between the groups for this outcome. Kwon added the same was found in motion with flexion and external rotation. While there were no intraoperative complications, results showed the standard group experienced two complications and the subscapular-sparing group had three complications. – by Casey Tingle
