Bristow-Latarjet procedure with specific instrumentation: study of 34 cases.

A Bristow-Latarjet procedure with specific instrumentation was performed for recurrent dislocation or subluxation of the glenohumeral joint in 34 patients. The procedure was performed through a subscapularis splitting approach with three specific instruments and a special screw. The clinical outcome was assessed by the Duplay and the Constant scores. Radiographic study was conducted on 23 patients and CT scan in 11 patients. Of the 27 patients interviewed 92% were satisfied. Of the 23 patients examined, 15 had an excellent Duplay score, four a good score, three a medium score, and only one had a bad score. One patient had subluxation episodes, and one patient was revised after a redislocation following violent trauma. On the standard radiographs, all bone blocks were in the correct position. A pseudarthrosis was diagnosed in the patient with subluxation episodes. This device simplifies the surgical technique and provides reproducibility to the procedure.
