Functional outcomes following lateral ulnar collateral ligament reconstruction for symptomatic posterolateral rotatory instability of the elbow in an athletic population.

Abstract：

HYPOTHESIS:The purpose of this investigation was to characterize the functional and surgical outcomes following lateral ulnar collateral ligament (LUCL) reconstruction for posterolateral rotatory instability in an athletic population. METHODS:All US military service members who underwent LUCL reconstruction between 2008 and 2013 were identified. A retrospective chart review was performed, and the prospective Mayo Elbow Performance Score and QuickDASH (short version of Disabilities of the Arm, Shoulder and Hand questionnaire) score were obtained. The primary outcomes were return to preinjury activity and resolution of symptoms. RESULTS:We identified 23 patients with a mean age of 31.6 ± 7.2 years (range, 19-46 years), and 87% were men. A history of instability and/or dislocation was reported by 11 patients (48%), and 8 patients (35%) had undergone prior elbow surgery. At final follow-up of 4.6 ± 1.8 years (range, 2.2-7.6 years), all patients demonstrated significant decreases in pain (average pain score, 4 vs 1.34) with resolution of instability and achieved a functional arc of motion. After surgical reconstruction, 83% were able to return to prior activity, whereas 4 patients (17%) underwent medical separation, including 3 with elbow disability precluding continued service (13%). Overall 83% of patients reported good to excellent outcomes by the Mayo Elbow Performance Score, and 96% of patients reported no significant disability by the QuickDASH disability evaluation. Postoperatively, 4 patients (17%) experienced complications, with 3 (13%) requiring reoperation. CONCLUSION:Although the diagnosis and surgical management of isolated LUCL injury are relatively infrequent, LUCL reconstruction for posterolateral rotatory instability offers a reliable return to preinjury level of function among active individuals with intense upper extremity demands. However, although function reliably improves, the rate of perioperative complications is greater than 15%.
