title: Bone loss in anterior instability.
abstract: Bone loss is commonly observed in shoulders with anterior instability. The Latarjet procedure is commonly performed when a glenoid bony defect exists that is greater than 25 % of the glenoid width or when the risk of recurrent instability is higher (i.e., collision-sport athletes). Hill-Sachs lesions need to be assessed as well. For the purpose of assessing the bipolar lesions, the glenoid track concept is useful. A Hill-Sachs lesion that is located more medially than the medial margin of the glenoid track is defined as an engaging Hill-Sachs lesion. A potential treatment for such a condition is remplissage, but this procedure also decreases range of motion. Thus, its application in overhead athletes needs to be carefully considered.
