[Impact of associated injuries on anterior glenohumeral instability treated with Latarjet surgery: functional outcomes at 2-year follow-up].

INTRODUCTION

in anterior glenohumeral dislocation, in addition to classic lesions such as Hill-Sachs (HS), Bankart, or glenohumeral anteroinferior ligament injury, other associated lesion like superior labral (SLAP), osteocondral (LOC), or glenolabral articular disruption (GLAD) have been described. Although open Latarjet surgery yields excellent outcomes, it does not address these associated lesions.

OBJECTIVE

to compare functional outcomes, recurrence rate, persistent symptoms and return to sport in patients undergoing open Latarjet surgery with and without associated lesions diagnosed by preoperative magnetic resonance imaging (MRI).

MATERIAL AND

METHODS

retrospective observational study. Patients who underwent open Latarjet surgery for anterior glenohumeral instability, with preoperative MRI and a minimum follow-up of two years, were included. Patients were divided into two groups, group 1: without associated lesions, and group 2: with associated lesions. Outcomes assessed included subjective shoulder value (SSV), visual analog scale (VAS), recurrence rate, persistent symptoms and return to sport.

RESULTS

28 patients were evaluated (age: 32 ± 6.8 years; 27 males, 1 female): 22 in group 1 and six in group 2 (associated lesions: 5 SLAP, 2 LOC, 1 GLAD). No significant differences between groups were found in SSV (92 ± 8.9 vs 85 ± 15, p = 0.29), VAS (1 vs 1, p = 0.6), recurrence rate (1 [4.5%] vs 0 [0%], p = 0.79) and persistent symptoms (7 [31%] vs 2 [33%], p = 0.65). There was a lower return to sport rate in group 2 vs group 1 (20 [90%] vs 3 [50%], p = 0.05).

CONCLUSIONS

patients with anterior glenohumeral dislocation treated with open Latarjet surgery and not treated associated injuries have lower return to sport rate after, with a minimum follow-up of two years.
