ON DISLOCATIONS OF THE THUMB AT THE METACARPO-PHALANGEAL JOINT;

Variation in extension of the metacarpo-phalangeal and interphalangeal joint of the thumb.

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...

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.

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 ...

Bilateral Carpometacarpal Joint Dislocations of the Thumb

A traumatic carpometacarpal joint dislocation of the thumb accounts for less than 1% of all hand injuries. Optimal treatment strategies for this injury are still a subject of debate. In this article, we report a case of bilateral thumb carpometacarpal joint dislocations: a unique combination of injuries. We believe our case is the second report of bilateral carpometacarpal joint dislocation reg...
