Dorsal Approach for Open Reduction of Complex Metacarpo-phalangeal Joint Dislocations

Dorsal approach for open reduction of complex metacarpophalangeal joint dislocations.

The metacarpophalangeal (MP) joint is resistant to injury due to its strong capsuloligamentous structures, which include the volar plate and deep transverse metacarpal and collateral ligaments. Complex MP joint dislocations are, by definition, irreducible by closed means and require open reduction, as the volar plate becomes entrapped between the metacarpal head and proximal phalanx. The dorsal...

Complex dorsal subluxation of the metacarpo-phalangeal joint of the thumb requiring open reduction: a case report.

The authors present an case of a thumb metacarpophalangeal joint dislocation which was made complicated by the interposition of the sesamoid bone which required open reduction. The intact volar plate prevented closed reduction. The anatomy and surgical management of this unusual case is described.

The natural history of the rheumatoid metacarpo-phalangeal joint.

Rheumatoid arthritis is a systemic disease usually presenting as a chronic progressive symmetrical inflammation of multiple joints. The metacarpo-phalangeal joints are the commonest sites of involvement, the initial lesion being a proliferative synovitis. As the disease progresses the proximal phalanx commonly subluxates volarward and is deviated ulnarward on the metacarpal head (Smith and Kapl...

Locking of the metacarpo-phalangeal joints.

Case 1-in January 1972 a nurse aged twenty years presented with locking of the left index finger. Earlier the same day she had been removing sutures, holding a forceps in the left hand, when the second metacarpo-phalangeal joint “locked” in the flexed position and she could not straighten it. She gave no history of any injury but said that during the preceding month she had noticed “cramps” in ...
