31-E/8 - Intraarticular flake(s)

The etiology of this chondral/osteochondral shearing lesion is traumatic hip dislocation.

The ostechondal flake is usually a single piece (31-E/8.1).

Rarely is it multifragmentary (31-E/8.2).

Note: It is important to distinguish between chronic osteochondrosis (osteochondritis) dissecans (OCD) and a traumatic lesion. OCD has a long history of hip pain and/or limited hip motion.
