A severe hamstring injury may also give rise to an avulsion fracture of the bone where it inserts into the pelvis & requires a lengthy rehabilitation process. The differences between Jones and avulsion fractures are small, but important. Some advocate the reduction of a bowing fracture where angulation exceeds 20 degrees. type I: avulsion of anterior glenoid margin; type II: transverse or oblique fracture through glenoid fossa exiting inferiorly; type III: oblique fracture through glenoid fossa exiting superiorly and associated with acromioclavicular joint injury; type IV: transverse fracture exiting through the medial Dorsal avulsion fractures account for about 95% all triquetral fractures, most of the remainder are body fractures 4.
