[Bristow-Latarjet repairs for anterior instability of the shoulder: clinical and radiographic results at mean 8.2 years follow-up]. / Traitement des instabilités antérieures de l'épaule par la technique de Bristow-Latarjet: résultats cliniques et radiologiques au recul moyen de 8,2 ans.

PURPOSE OF THE STUDY: We reviewed, at a mean follow-up of 8.2 years, clinical and radiographic results after 93 Bristow-Latarjet procedures for anterior instability of the shoulder. MATERIAL AND METHODS: There were 84 men and nine female. The average age was 23 years at the time of operative intervention. Forty-four shoulders were on the dominant side. Eighty patients practiced sports activities, with 74 patients a risk sport. Seventy-seven patients have had five or more recurrent of dislocation of the shoulder. The operations were performed by a senior surgeon. Evaluation was done by a clinician, who did not perform the operation. Clinical outcome was assessed with the Duplay score, and the satisfaction of the patients. Radiographic evaluation was done using the standard radiography of the shoulder. RESULTS: According to the Duplay scoring system, we have had 30.1% of excellent results, 43% of good results, 16.1% of fair results, and 10.8% of poor results. The mean Duplay score was 84.7 points with 19 points for the return in sports, 23 points for the stability, 21 points for the pain, and 22 points for the movement. The loss of rotation was less than 13 degrees (mean). Among the patients, 57.4% returned to their former sports activities at the same level, with 59.8% a risk sports. Five patients reported redislocation and eleven patients reported apprehension. The patients were painless in 75.8%. Forty-four patients were very satisfied or satisfied at follow-up. At review, there were radiological degenerative changes in nine shoulders: six in Samilson grade I, one grade II, and two grade III. There was no radiological evidence of loosing, migration or fracture of the coracoid screws, and no nonunion. We have had six cases of resorption of the coracoid tip. DISCUSSION: We are aware of the limitation of the study. It is a retrospective study and there is no control group. However, we believe that, in regard of our result, the Bristow-Latarjet procedure for anterior glenohumeral instability is safe and effective with good objective and subjective result, and a high degree of patient satisfaction. Radiological findings do not always correlate with the functional outcome and patient satisfaction. CONCLUSION: Although it is a non-anatomical repair, the Bristow-Latarjet procedure provides desirable functional results.
