Open dorsal metacarpophalangeal dislocations of the index, long, and ring fingers

An open dorsal dislocation of the metacarpophalangeal joints of the index, long, and ring fingers was treated satisfactorily by early reduction.     

Volar dislocation of the metacarpophalangeal joint of the thumb--a case report

A patient with a volar dislocation of the metacarpophalangeal joint of the thumb is reported in which closed reduction proved impossible because of the interposition of the dorsal capsule, extensor pollicis longus tendon and extensor pollicis brevis tendon in the metacarpophalangeal joint. The collateral ligament was also ruptured. Therefore open reduction is recommended for similar cases.     

Volar dislocation of the metacarpophalangeal joint of the ring finger. Report of two cases.

Volar dislocation of the metacarpophalangeal joint of the finger is a rare injury. Two cases of an isolated volar dislocation of the ring finger metacarpophalangeal joint are reported. The dislocation was treated successfully by closed reduction shortly after injury in both cases. Closed reduction should be attempted in all cases of this injury because successful reduction may be possible.     

Volar dislocation of the first metacarpophalangeal joint. A case report and review of the literature

After suffering traumatic volar dislocation of the first metacarpophalangeal joint, a 27-year-old patient was treated using closed reduction of the thumb. The patient regained full function and stability of the joint after 5 months. A review of the literature indicates that open reduction is the most common treatment for volar dislocation, but our case report suggests that conservative treatment using closed reduction can be highly effective.     

Complete dorsal dislocation of the metacarpophalangeal joint of the thumb

In the pathology of simple complete dislocation involving the metacarpophalangeal joint of the thumb, whether or not the palmar plate is interposed within the joint is controversial. Nine cases of complete dorsal dislocation of the joint were reviewed, and cadaver dissection was performed to study the pathology of this injury. Eight of the nine patients were seen within 4 days of injury and treated successfully by closed manipulation. One patient treated 7 days after the injury required open reduction. We were able to reproduce the pathological anatomy of the dislocation, wedging of the palmar plate in the joint of the cadaver. In this cadaver and in all clinical cases, radiographs showed a complete dislocation with an increased distance between the palmar edge of the base of the proximal phalanx and the metacarpal head, indicating an interposition of the palmar plate. Our study suggests that in simple complete dislocations of this joint, the palmar plate is interposed between the displaced bones. Received: 16 December 1997     

Volar open reduction of complex metacarpophalangeal dislocation of the index finger: a pictorial essay

Dislocations of the metacarpophalangeal joint are uncommon and usually caused by significant trauma. The distinction between subluxations and dislocations is critical. Complex dislocations require surgical reduction. The need for surgical reduction is primarily due to the anatomy of this region, which contributes to the complexity of this injury and to the degree of difficulty in its reduction. This pictorial essay aims to highlight the clinical, radiographic, and surgical features of this uncommon yet complex injury.     

Trapezo-metacarpal and metacarpo-phalangeal dislocation of the thumb associated with a carpo-metacarpal dislocation of the four fingers

The authors report a case of combined dorsal fracture-dislocations of all 4 fingers, palmar trapezo-metacarpal dislocation and metacarpophalangeal dislocation of the thumb following a motorbike accident. These exceptional lesions were treated as an emergency by reduction and pinning. With a follow-up of 13 years, the patient still worked as an electrician.     

Volar dislocation of four ulnar metacarpals: one case report

We report a case of volar dislocation of four ulnar carpometacarpals. It's a very rare injury, especially as it affects all long fingers, it is volar and has no fractures. The treatment consisted in open-reduction with pinning carpometacarpal according to intraoperative stability. No complications was noted. The follow-up was a radiological evaluation (pain, strength, mobility) between 6th week and 6th month. The recovery was complete at 6 months without pain. We believe that open reduction allows carpometacarpal osteosynthesis to be the less invasive as possible, depending on the stability visualized and thus can reduce stiffness and residual pain.     

Simultaneous dorsal dislocation of the metacarpophalangeal and carpometacarpal joints of a finger

A case of simultaneous dorsal dislocation of the metacarpophalangeal (MP) and carpometacarpal (CMC) joints in the little finger is presented. The patient required a second surgical intervention for volar subluxation of the MP joint which occurred while wearing a dorsal splint following open reduction of the MP joint and closed reduction of the CMC joint. Two years postoperatively, the patient was asymptomatic but was left with mild stiffness of the MP joint.     

Simultaneous subluxation of the metacarpophalangeal joints of all four fingers: a case report

Simultaneous subluxation of the metacarpophalangeal joints of all four fingers is rare, and we have found no cases in the literature. A 45-year-old construction worker fell and dislocated the metacarpophalangeal joints of all the fingers of his left hand. Closed reduction by manipulation was successfully accomplished, and the patient returned to work within 5 months of his accident. He had a full range of motion 1 year later.     

Complete dorsal dislocation of the carpal scaphoid with perilunate dorsal dislocation

Complete dorsal dislocation of the carpal scaphoid combined with dorsal perilunate dislocation is an extremely rare carpal injury. We describe the case of a 23-year-old man who presented with a complete dorsal dislocation of the carpal scaphoid, combined with a perilunate dislocation. Surgical treatment was performed with open reduction and interosseus ligament repair. At 4 years follow up, the patient''s wrist pain had completely resolved without limitations of wrist joint motion and without evidence of avascular necrosis of the carpal scaphoid.
