Abstract Background Recent studies have reported the theoretic amount of coracoid graft available for harvesting with the Latarjet procedure. Our aim was to investigate the actual dimensions of coracoid grafts harvested using a standardized technique. We also hoped to confirm previous recommendations regarding placement of the inferior glenoid drill hole to avoid lateral overhang of the graft. Materials and methods Intraoperative measurements were taken after coracoid graft harvesting and preparation during the Latarjet procedure. Specifically, we measured the length of coracoid, thickness of coracoid, distance from the inferior drill hole to the lateral margin of the graft, distance between drill holes, width at the level of the superior drill hole, and width at the level of the inferior drill hole. Results Data were collected from 76 Latarjet procedures (67 men, 9 women). Patients were an average age of 28.7 years (range 16-67 years). Mean measurements were length of coracoid graft, 26.4 ± 2.9 mm; thickness, 9.3 ± 1.4 mm; distance from the edge of the inferior drill hole to the lateral margin of the graft, 5.7 ± 1.1 mm; distance between drill holes, 7.8 ± 1.9 mm; width at the level of the superior drill hole, 14.1 ± 1.8 mm; and width at the level of the inferior drill hole, 13.3 ± 1.8 mm. Conclusions Using a standardized surgical technique that does not violate the coracoclavicular ligaments, a coracoid graft greater than 25 mm can routinely be harvested for the Latarjet procedure. The inferior glenoid drill hole should typically be placed at least 7 mm from the glenoid margin to avoid lateral overhang.
