Is the Latarjet procedure risky? Analysis of complications and learning curve.

<bold>Purpose: </bold>The purpose of this study was to analyse the learning curve and complication rate of the open Latarjet procedure.<bold>Methods: </bold>The first 68 Latarjet procedures performed by a single surgeon for chronic anterior shoulder instability were reviewed retrospectively. The standard open surgical technique was followed faithfully during each procedure. Post-operative complications were taken from patient medical records. Post-operative evaluation consisted of clinical and radiological assessments.<bold>Results: </bold>The rate of early (<3 months) clinical complications was 7.4 % (5.9 % haematoma, 1.5 % neurological deficit), and the delayed complication rate was 7.3 %. Early complication rate, duration of surgery (mean 65 min; 35-135) and hospital stay (mean 3 days; 1-4) were significantly reduced as experience increased (respectively; P = 0.03, ρ = - 0.3; P = 0.009, ρ = - 0.3; P < 0.0001, ρ = - 0.6). On the radiographs, the bone block was healed and in perfect position in 87 % of cases, with no effect of surgical experience (P = 0.3, ρ = 0.1). The rate of complications on radiographs was 17 %: 11 % partial lysis, 2 % complete lysis and 4 % non-union. No recurrence of instability was found after an average follow-up of 21 months.<bold>Conclusion: </bold>Despite a high rate of post-operative complications, the morbidity of Latarjet procedure remains low. A surgeon's experience significantly affects the surgery duration and the occurrence of early complications. The main radiological complication is partial lysis of the bone block. After a short learning curve, the clinical outcomes of the Latarjet procedure appear to be satisfactory and reproducible.<bold>Level Of Evidence: </bold>IV. [ABSTRACT FROM AUTHOR]
