Patient Data

Age: 20
Gender: Female

There is a 3mm bony fragment on the dorsal aspect of the capitate - appearances suggest an avulsion fracture. There is sclerosis of the mid / distal capitate. There is minimal associated subcutaneous soft tissue swelling. The articular surface appears intact. There is no separation of the ulnar styloid process. The adjacent joint alignment appears normal. 



There is a transverse fracture of the middle - distal third of the capitate bone. The fracture line is sclerotic in keeping with longstanding injury. No callus formation is identified. There are small bony fragments on the dorsal and volar aspect of the capitate bone - the largest measures 4 x 2mm on the dorsum and corresponds to the bony fragment noted on the x-ray.

There is at least one 2mm intra articular loose body / bony fragment in the capitate lunate joint and a bony fragment in the capitate trapezoid joint. The bone density of the capitate is otherwise within normal limits with no signs of avascular necrosis. 

Case Discussion

There are appearances of non-union of the capitate bone fracture with intra-articular loose bodies.
