Revision of failed Latarjet with the Eden-Hybinette surgical technique.

INTRODUCTION

The outcomes of the Latarjet procedure for anterior shoulder instability are highly satisfactory although recurrences are possible. Surgical revision is challenging, and often requires an iliac crest bone graft as described by Eden and Hybinette. The aims of our study were to analyze the outcomes of the Eden-Hybinette technique after failed Latarjet procedure, determine the failure and complication rates, and analyze the risk of osteoarthritis. We hypothesized that the Eden-Hybinette technique would yield good outcomes after failed Latarjet procedure.

MATERIAL AND METHODS

Retrospective multicenter study (9 hospitals) by the French Shoulder and Elbow Society (SoFEC) involving 46 patients who underwent revision surgery with an Eden-Hybinette procedure after failed Latarjet stabilization. The patients had a minimum follow-up of 1year and the outcomes were evaluated based on the Rowe score, Walch-Duplay score and radiographs.

RESULTS

The mean age at the final assessment was 32years. The mean follow-up was 38 months and 86% of patients had a stable shoulder with an overall satisfaction rate of 80%. Postoperatively, the Rowe score averaged 76/100 and the Walch-Duplay score averaged 68/100; 60% of patients had resumed their sports participation. Return to sport was statistically correlated with age (p=0.0001), osteoarthritis (p=0.05) and time elapsed between the two surgical procedures (p=0.0001). The Rowe score was statistically correlated with osteoarthritis (p=0.01).

DISCUSSION/CONCLUSION: Our study is one of the largest on the Eden-Hybinette procedure for recurrent anterior shoulder instability. The outcomes at 3years' follow-up were satisfactory in 80% of patients and 86% had stable shoulders. The osteoarthritis rate was low (11%), although the follow-up period was relatively short.

LEVEL OF EVIDENCE

IV, non-randomized multicenter retrospective study.
