Isolated dorsal approach for the treatment of neglected volar metacarpophalangeal joint dislocations

Here, we present the clinical and radiological results of three neglected volar metacarpophalangeal dislocations in 2 patients, which were treated with open reductions 10 and 24 mo after the dislocations. There was a mean of a 20°(range 10°-30°) limitation of extension and a 53.3°(range 30°-70°) limitation of flexion preoperatively. Postoperatively, there was no limitation of extension(at 8 and 12 mo) in any of the fingers. In terms of flexion, one finger had full function, one had a 10° and the last one had a 30° limitation of flexion. Two of the fingers presented anesthesia preoperatively, which improved to hypesthesia postoperatively. One finger had hypesthesia, which improved postoperatively. During surgery, a ruptured dorsal capsule was found to have interposed into the joint, making closed reduction impossible. Our experience with these two patients demonstrated that, even in neglected cases, open reduction using an isolated dorsal approach may result in satisfactory clinical andradiological outcomes.

Case Report: Osteochondral Fragment—A Rare Cause of Locked metacarpophalangeal Joint

引用

Surgical Science 2011年第6期2卷 353-355页

作者： Kelvin Ramsey S. Overstall A. Fleming St. George"s Hospital

We describe the presentation of a patient with sudden, sharp pain associated with a snapping sensation, swelling and pain over the metacarpophalangeal joint (MCPJ) with no history of direct trauma. The finger was held in 30 degrees of flexion and significantly deviated to the ulnar side with loss of extension. A diagnosis of traumatic rupture of the radial sagittal band of the extensor mechanism was made but the cause at exploration was found to be impingement of an osteochondral fracture fragment. This is a rare cause of irreducible loose body ‘locking’ of the metacarpophalangeal joint.
