Purpose: The purposes of this study were to assess the effects of a distal clavicle resection of less than 5 mm on bony contact and compliance in the acromioclavicular (AC) joint and to localize areas of persistent contact in the AC joint. The hypothesis of this study was that AC contact can be avoided by excising less than 5 mm of bone from the distal clavicle.
Methods: Ten human AC joints underwent compressive loading of the distal clavicle into the acromion after the following: disk excision, distal clavicle resection of 2.
