Updates to Article Attributes
Body
was changed:
Elbow involvement in osteochondritis dissecans is rare. It is defined as a localised fragmentation of bone overlying the capitellum cartilage. For a general discussion of osteochonritisosteochondritis dissecans refer to the parent article - osteochondritis dissecans.
Epidemiology
Most commonly seen in young baseball pitchers.
Pathology
Occurs due to repetetiverepetitive compression type of injury leading to vascular insufficiency and microtrauma. Typically affects the capitellum of dominant hand.
Clinical presentation
Features may include
- pain along the lateral elbow
- swelling
- laxity of medial collateral ligament
Radiographic features
Plain radiography
- non specific findings
- mostly normal
- may show irregularities and fragmentation of capitellum
CT and MRI
Helpful in determining the stability of the lesion .:
- CT arthrogram is more useful
- early changes are detectable on T1 weighted images and normal on T2 images
- advanced changes are depictable in both T1 and T2 images
