Clinical and radiographic outcomes of the open Latarjet procedure in skeletally immature patients.

Abstract

Recurrent anterior glenohumeral instability has been studied in the young population and limited evidence is available for adolescent patients. Our study is a retrospective review of patients aged <17 years who underwent open Latarjet procedure. Forty-five patients were available for review. Clinical outcomes were assessed by range of movements, stability, Walch-Duplay score (WDS), Rowe score (RS), Constant-Murley score (CMS), Subjective Shoulder Value (SSV), and return to sport. Radiographs were reviewed for osteoarthritis and complications. The median age of patients was 15.7 years (13-17), and 56% had hyperlaxity. The median follow-up time was 6.6 years (3-26). The median postoperative movements showed recovered elevation (175°), external rotation (60°), and internal rotation (T9 level). Seventy-five percent of patients returned to the same level of sport, and 98% were satisfied. Clinical outcomes showed WDS, RS, and CMS scores of 85, 95, and 84 points, respectively, and an SSV of 95%. Twenty percent of patients described mild postoperative pain, and 1 had persistent stiffness. Other complications included 24% subjective apprehension, 4% redislocation, 4% wound problems, and 2% infection. Nine percent of cases had postoperative arthritis. The overall reoperation rate was 11%: 1 open washout for infection and 4 arthroscopic screw removal due to persistent pain. We found that hyperlaxity, female sex, and large or deep Hill-Sachs lesions were frequently associated with persistent apprehension at the last follow-up. The open Latarjet procedure provides a low rate of recurrent instability with acceptable complication rates in the long term for skeletally immature patients. It is an effective, safe treatment option without any significant glenoid growth disturbance.
