 Backgroud:The arthroscopic Latarjet or Bristow procedure has recently come to be performed to treat traumatic anterior shoulder instability in patients with a large glenoid bone defect. Since 2007 we have been performing coracoid transfer by a combined open and arthroscopic procedure (hybrid coracoid transfer). The purpose of this study was to evaluate the surgical and radiographic outcome of patients who underwent this procedure.

 Methods:We evaluated the outcome in nine shoulders treated by arthroscopic coracoid transfer for traumatic anterior shoulder instability with greater than 25% glenoid bone loss. All of the patients were male, and their average age at surgery was 23.1 years old (range:16−46). We assessed complications, recurrence of instability, progression of osteoarthritis and pseudoarthritis on X-ray films, the position of the graft on CT scans, and the ① medial-lateral position of the graft in relation to the joint surface and ② coverage of the glenoid defect were also evaluated. The average follow-up period was 17 months (range:9−44).

 Results:The only postoperative complication was a hematoma that occurred in 1 shoulder. There were no surgical wound infections, nerve injuries, or recurrences of instability. Progression of osteoarthritis and pseudoarthrosis was noted in 1 shoulder. The graft was flush against the glenoid surface in all shoulders. The coverage rate was greater than 75% in 7 shoulders and 60−74% in 2 shoulders.

 Conclusions:Although longer follow-up for redislocation and osteoarthritis progression will be necessary, satisfactory placement of the graft was achieved by the hybrid coracoid transfer.
