Osteochondrosis dissecans of the elbow.

Author information

Department of Radiology, University Hospitals Leuven, Leuven, Belgium.


This case shows a typical presentation of an osteochondrosis dissecans lesion on the capitellum, with associated intra-articular loose bodie(s), diagnosed on plain film. Osteochondrosis dissecans (OCD) is a rather common entity. Mostly the knee joint is involved. Only 5% of OCD lesions occur in the elbow joint. Possible causes of osteochondrosis dissecans include (repetitive) trauma (e.g. in throwing sports or gymnastics), ischemia, ossification defects, and genetic factors. Conventional radiography mostly has a low sensitivity to detect OCD lesions, and is often normal in early stages. CT is more sensitive to detect intra-articular loose bodies. MRI detects very early stages of OCD and radiographically occult lesions that may not be evident on CT.
