Pathogenesis of some traumatic and degenerative disorders of soft tissue.

1. Trauma to soft tissues is associated with tissue rupture and formation of a haematoma. 2. Such lesions cannot be expected to resolve without complications in the absence of appropriate treatment. 3. Myositis ossificans should be anticipated in lesions of muscles adjacent to their attachments. 4. Chronic tendonitis and enthesopathies not associated with inflammatory connective tissue disease are primarily degenerative in nature and are probably the result of comparative ischaemia. Mesenchymoid transformation is a feature of both.
