Osteochondritis dissecans of the elbow
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 osteochondritis dissecans refer to the parent article - osteochondritis dissecans.
Epidemiology
Most commonly seen in young baseball pitchers.
Clinical presentation
Features may include:
- pain along the lateral elbow
- swelling
- laxity of medial collateral ligament
Pathology
Occurs due to repetitive compression type of injury leading to vascular insufficiency and microtrauma. Typically affects the capitellum of the dominant hand.
See the main osteochondritis dissecans article for a general discussion on this condition pathology.
Radiographic features
Plain radiograph
- 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 depicted on both T1 and T2 images
Differential diagnosis
- Panner disease: capitellar osteochondrosis 2
