Post-operative computed tomographic imaging of the shoulder joint

Between 1984 and 1990 312 patients underwent surgery for habitual or recurrent shoulder dislocation. Out then, 65 had a post-operative CT examination. This retrospective study was launched to demonstrate the value of CT in post-operative shoulder imaging. In most cases, CT was done using standardised techniques without contrast medium. Except in 4 cases, an intra-articular double-contrast technique was used. Evaluation was focused on 41 cases after implantation of a wedged bone graft in cases of primary or secondary flat glenoid or widening of a small glenoid with cortical consoles and bone block. The results demonstrate the effectiveness of standardised CT technique in that all necessary information concerning stabilisation of the shoulder joint, sufficient implant of bone grafts and assessment of correct inclination after osteotomy were obtained.
