DENVER — Patients with posterolateral rotatory instability who underwent lateral ulnar collateral ligament reconstruction experienced an improved level of function, according to results presented here.

“We found that, despite a moderate complication rate, [lateral ulnar collateral ligament] L-UCL reconstruction did reliably restore stability to the elbow and offers [a] functional resolution for patients with [posterolateral rotatory instability] PLRI allowing them to return to their preinjury level of function,” Marina Rodriguez, MD, said in her presentation at the Arthroscopy Association of North America Annual Meeting.

Rodriguez and colleagues obtained demographic data and perioperative factors, such as range of motion and complications of revision surgeries, among 23 U.S. military service members with posterolateral rotatory instability treated with lateral ulnar collateral ligament reconstruction from January 2008 to April 2013.

All patients reported relief of their instability symptoms and decreased pain and had achieved a functional arc of motion at final follow-up of 4.6 years. Rodriguez noted 82% of patients reported good to excellent outcomes with the Mayo Elbow Performance Score.

“Similarly, with the QuickDASH evaluation, 5% of patients reported scores indicating limited, if any, problems with functionality of their elbow,” Rodriguez said.

She added 17.4% of patients experienced a postoperative complication. Of these, three patients required a reoperation. Overall, six patients were able to deploy postoperatively and 19 patients either continued on active duty or completed their term of service.

“Multivariate analysis was performed and identified only age less than 30 [years] being associated with improved Mayo Elbow Performance Scores,” Rodriguez said. – by Casey Tingle
