Mar 24, 2025 · Metacarpophalangeal joint (MCPJ) dislocations are uncommon dislocations of the hand. Metacarpophalangeal joint dislocations account for ~3-5% of all dislocations 1,2. The thumb is the most commonly affected digit, followed by the little finger 2.

Sep 8, 2024 · MCP Dislocations are a dislocation of the metacarpophalangeal joint, usually dorsal, caused by a fall and hyperextension of the MCP joint. Diagnosis can be made clinically and is confirmed by orthogonal radiographs. Treatment is closed reduction unless soft tissue interposition blocks reduction, in which case open reduction is indicated.

Feb 24, 2025 · Metacarpophalangeal (MCP) joints are condyloid synovial joints between the metacarpal bones and proximal phalanges of the hands. This article is focused on the metacarpophalangeal joints of the fingers. Each joint occurs between the round head of the metacarpal and the shallow base of the proximal phalanx 1,2.

X-ray can be used to check for underlying bone injury and to reassess following reduction of the dislocation. Some finger fractures are easy to identify, but others are more difficult to spot because of overlying bones or soft tissues. The most common metacarpal fracture is …

X-ray. X-rays are often the initial imaging technique used to assess the MCP joint. They can detect bone abnormalities, such as fractures, joint dislocations, and the presence of bone spurs or erosions. Magnetic Resonance Imaging (MRI)

X-ray imaging showed a dorsal MCP dislocation of the index finger with an entrapped sesamoid bone . A CT scan confirmed the dislocation at the second MCPJ and revealed a sesamoid bone within the joint, alongside a non-displaced fracture at the base of the second metacarpal ( Fig. 3 ).

Prereduction and postreduction x-ray films are necessary to demonstrate associated fractures and joint congruency. An incongruent joint can be caused by interposed soft-tissue or gross...

The complex multiple MCPJ dislocation was treated successfully with closed reduction under wrist block. The patient is in regular follow-up with no recurrence and good hand function at the end of one

6 days ago · Stress x-rays should only be done after static x-rays to prevent nondisplaced fractures from becoming displaced fractures. In the thumb, MCP joint laxity >30–35 degrees on stress x-rays is usually associated with a complete collateral ligament tear.

Metacarpophalangeal (MCP) Joint arthritis typically presents with pain, swelling, and limited motion. Inflammatory etiology is much more common than osteoarthritis. in patients with osteoarthritis, a tendon-splitting approach can be used.
