title: Ultrasound follow-up of posttraumatic injuries of the sagittal band of the dorsal hood treated by a conservative approach.
abstract: Traumatic dislocation of the extensor tendon over the metacarpophalangeal (MCP) joint is a rare problem in patients without rheumatoid disorders. The common extensor tendon is stabilized on the metacarpal head by components of the dorsal hood (DH). A tear in the sagittal bands, allows (sub)luxation of the tendon. To ensure appropriate treatment, the identification of the damaged structures is essential. Ultrasound (US) is a valuable method in the evaluation of DH injuries and in the follow-up for evaluation of healing or lack of healing of the lesions. We report three cases with partial rupture of the sagittal band of the DH: two cases in the index finger and one case in the long finger, which caused pain and swelling and was diagnosed with US. The patients were treated conservatively and the pain resolved after 9 months in case 1, 3 months in case 2 and 6 months in case 3. The follow-up at one year revealed painless full range of motion and no residual subluxation during the dynamic ultrasound.
