Abstract

Background: The Latarjet-Patte (L-P) procedure is indicated in anterior instability of the shoulder with a glenoid or humeral bone loss. Our purpose is to evaluate clinical outcome and computerized tomographic (CT) findings as position and resorption of the graft and articular degeneration.

Methods: From 2006 to 2009 50 patients underwent to L-P, 48 was contacted by telephone and 26 were available for follow-up (3 to 6 years). Quick-DASH and Rowe scores was used, 22 patients perform CT.

Results: None of contacted patients reported a new dislocation. The clinical outcome in the 26 followed patients was excellent: mean Quick DASH score: 1.9; mean ROWE score was 94.7. CT scans showed no evidence of articular degeneration of humeral head. There was partial resorption of the graft in 13 patients. We found a correlation between the zone of partial resorption and position of the graft.

Conclusions: CT scan is appropriate to study position and the healing of coracoid graft. A correct choice of where to place the graft together with a wide bone contact and stable synthesis does not cause degenerative changes after 6 years in our series.

Level of the evidence: IV.
