AI Article Synopsis
- A case of a thumb MCP joint dislocation was complicated by the interposition of sesamoid bones, leading to a condition known as "locked thumb" syndrome.
- The sesamoid bones became trapped at the base of the dislocated proximal phalanx, obstructing the typical reduction procedure.
- As a result of this blockage, closed reduction attempts were unsuccessful, necessitating surgical intervention.
Article Abstract
We present a case of a thumb metacarpophalangeal (MCP) joint dislocation complicated by the interposition of the sesamoid bones. This case highlights a clinical scenario referred to as the "locked thumb" syndrome, in which a first-digit MCP dislocation is complicated by an entrapped anatomical structure that hinders closed reduction. In this case, the thumb sesamoid bones became lodged at the base of the dislocated proximal phalanx. Due to this mechanical blockage, bedside closed reduction failed, and operative management was required.
