Patients were excluded if CT demonstrated osteophyte formation, glenoid dysplasia, coracoid fracture, or tumor. The proportion of glenoid diameter able to be restored using classic Latarjet technique and CAM were calculated. A treatment algorithm was proposed considering the amount of bone loss present and coracoid dimensions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Coracoid dimensions of 117 consecutive patients were measured and varied considerably (length: 17.5\u201031.8 mm, width: 9.1\u201020.5 mm, thickness: 6.1\u201015.7 mm). While most patients had harvestable coracoid length \u226520 mm (male: 96.3% vs female: 94.4%,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .65), only 27.8% of female patients had coracoid thickness \u226510 mm. When comparing Latarjet techniques, there was no difference in the proportion of patients in whom 30% glenoid diameter could be fully restored, but CAM was able to restore at least 35% in more male and female patients (98.8% vs 79.0% and 100% vs 61.1%, respectively,\n                      <jats:italic>P<\/jats:italic>\n                      \u00a0= .00001).

The classic Latarjet technique reliably restores the glenoid anteroposterior diameter with bone loss of up to 30%. The majority of female patients have coracoid thickness &lt;10 mm, which may increase the risk of graft fracture when using CAM. The decision to use the classic Latarjet technique or CAM considers each individual\u2019s glenoid and coracoid dimensions with a goal of achieving an on\u2010track shoulder.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Clinical Relevance<\/jats:title>\n                    <jats:p>Our reliable method of coracoid measurement demonstrated the differing abilities of the classic Latarjet and CAM to restore the native glenoid diameter. An evidence\u2010based algorithm using these measurements was developed to assist in preoperative planning for glenohumeral instability in the setting of bone loss, with a goal of achieving an on\u2010track shoulder.
