The posterior glenoid bone defect was characterized using the following measures: (1) percentage of bone loss, (2) glenoid vault version, (3) slope of the posterior defect relative to the glenoid surface, (4) superior\u2010inferior length of the defect, and (5) anterior\u2010posterior width of the defect at 5 intervals along the glenoid fossa.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The mean age of the 40 patients was 22.9 \u00b1 5.5\u00a0years (range, 14.9\u201035.5\u00a0years). The mean surface area of glenoid bone loss was 9.7% \u00b1 4.7%. Glenoid version measured at 5 equal intervals along the inferior two\u2010thirds of the glenoid was 12.8\u00b0 \u00b1 4.9\u00b0, 11.9\u00b0 \u00b1 5.0\u00b0, 10.1\u00b0 \u00b1 6.3\u00b0, 10.5\u00b0 \u00b1 6.5\u00b0, and 8.7\u00b0 \u00b1 7.2\u00b0 from superior to inferior. The mean slope of the posterior defect relative to the glenoid fossa was 26.8\u00b0 \u00b1 11.5\u00b0. The mean superior\u2010inferior height of the bony defect was 21.9 \u00b1 0.4\u00a0mm. The anterior\u2010posterior sloped width of the defect at 5 equal intervals along the glenoid fossa was 0.9 \u00b1 1.5\u00a0mm, 2.8 \u00b1 2.4\u00a0mm, 4.0 \u00b1 1.7\u00a0mm, 4.0 \u00b1 2.1\u00a0mm, and 2.9 \u00b1 2.6\u00a0mm from superior to inferior. Low\u2010grade (&lt;10%) bone loss was diagnosed in most shoulders (23 of 40 evaluated), whereas 15 had moderate bone loss (10% to &lt;20%) and 2 had high\u2010grade bone loss (\u226520%).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Posterior glenoid bone loss is characterized by a loss of posterior bony concavity, increased slope from anterior to posterior, and increased posterior version. The most anterior\u2010posterior sloped width was quantified at the third and fourth intervals of 5 equal intervals from superior to inferior. This study highlights that patients with posterior instability have bone loss that is sloped relative to the glenoid fossa and suggests that management must be appropriately tailored given the distinctiveness of posterior bone loss.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Level of Evidence<\/jats:title>\n
