Bone bruise
Updates to Article Attributes
Bone bruise (also known as bone contusion, trabecular microfracture) is an osseous injury which results from compression of bone structures.
Pathology
Bone contusions represent trabecular microfractures with haemorrhage and without a discrete fracture line or contour abnormality 4. They typically appear within 48 hours of injury and can persist for up to six months 3.
Aetiology
Most bone contusions are a result of a direct blow to the bone, traction from avulsion trauma or load to a subchondral surface 1,2,5. Depending on where bone contusion is seen, the underlying trauma mechanism can be identified.
Complications
They can progress to osteochondritis dissecans 2.
Radiographic features
Plain radiograph
Plain radiography will not demonstrate cancellous features but can show regions of impaction, for example, a Hill-Sachs lesion 5.
MRI
MRI is the modality of choice when investigating bone marrow. Bone (marrow) contusion is typically ill-defined with the following signal characteristics 4:
- T1: hypointense area of bone marrow that is affected
- T2: hyperintense area of bone marrow that is affected
