  		Fig. 1A —45-year-old man with recurrent shoulder dislocation. Calibration probe inserted through posterior arthroscopic portal with tip of probe at posterior margin (A), bare spot (B), and anterior margin (C). Distance from posterior margin to bare spot is longer than from bare spot to anterior margin, thus indicating glenoid bone loss.

  		Fig. 1B —45-year-old man with recurrent shoulder dislocation. Calibration probe inserted through posterior arthroscopic portal with tip of probe at posterior margin (A), bare spot (B), and anterior margin (C). Distance from posterior margin to bare spot is longer than from bare spot to anterior margin, thus indicating glenoid bone loss.

  		Fig. 3A —CT images reconstructed en face to glenoid fossae in 37-year-old man with recurrent unilateral dislocation. Normal side shows normal curved anterior glenoid rim (arrows). Glenoid width (solid line), measured at right angles to long axis of glenoid (dashed line), measures 28.4 mm.

  		Fig. 3B —CT images reconstructed en face to glenoid fossae in 37-year-old man with recurrent unilateral dislocation. On dislocated side, there is anterior straight line to anterior glenoid rim (arrows). Glenoid width (solid line), measured at right angles to long axis of glenoid (dashed line), measures 24.7 mm. Glenoid bone loss is difference in glenoid width (3.7 mm) divided by normal width (28.4 mm) x 100 = 13% glenoid bone loss.

  		Fig. 4 —Graph shows correlation between glenoid bone loss measured at arthroscopy and at CT examination. Pearson's correlation coefficient (r) was 0.79, with 95% CI of 0.659–0.877.
