PURPOSE: The purpose of this study was to determine quantitatively whether the Latarjet procedure (coracoid transfer to the glenoid) is sufficient to restore a significant defect area of the glenoid. METHODS: Fourteen cadaveric shoulders were used (mean age, 76 years; range, 72 to 87 years). An anteroinferior glenoid defect was created and then the coracoid osteotomized to its angle and transferred to the defect. A 3-dimensional computed tomography scan was used to calculate the surface area of (1) the intact glenoid, (2) the osteotomized glenoid, and (3) the reconstructed glenoid. RESULTS: The mean area of the intact inferior glenoid was 734 +/- 89 mm(2). After creation of the defect, the surface area of the glenoid was reduced significantly to 523 +/- 55 mm(2) (P = .011). The mean defect area was 28.7% +/- 6% of the intact glenoid. After coracoid transfer, the mean surface area of the reconstructed glenoid was 708 +/- 71 mm(2) but it was not significantly smaller than that of the intact glenoid (P = .274). The mean surface area of the coracoid that was used to repair the defect was 198 +/- 34 mm(2), or 27% +/- 5% of the intact glenoid. CONCLUSIONS: In our cadaveric model, a mean 29% defect size of the inferior glenoid was restored to normal after coracoid transfer by use of the Latarjet procedure. CLINICAL RELEVANCE: In the clinical scenario, the existence of a glenoid bone defect of more than 25% to 30% is very rare in patients with anterior shoulder instability. Therefore, when clinically indicated, large bony defects of the anterior glenoid can be adequately treated by the Latarjet procedure. 2010 Arthroscopy Association of North America.
