- results from failure of an anterior acromial ossification center to fuse to the acromial process;
- caused by failure of one of three ossification centers;
- ossification centers appear at age 15 and should fuse by age 22-25;
- subtypes: (from anterior to posterior)
- preacromion, mesacromion, metacromion, and basiacromion types;
- mesacromion and metacromion are most common;
- patients may show impingement like symptoms but will also have localized tenderness;
- strong association with
