Axial computed tomography scan showing fracture of glenoid rim distal to a well-fixed anchor in a patient who had a shoulder dislocation while skiing after prior successful arthroscopic stabilization.

Axial computed tomography scan of inferior anchor. The glenoid rim was observed to have fractured distal to a well-fixed anchor.

Three-dimensional computed tomography scan of glenoid with metallic enhancement technique. The fracture was observed between the middle and inferior anchors at the level of the drill holes for the 2 anchors.
