“…The mechanism of injury causing MCPJ and CMCJ dislocation is thought to be a force that acts in a longitudinal and slightly dorsal direction along the axis of a fully extended digit. 4 Such a force produces a dorsal dislocation in the distal joint, followed rapidly by dislocation of the more proximal joint as the force continues to act in the same plane. Though a dorsal dislocation is commonest, rarely a palmar dislocation of the MCP joint can occur.…”

“…The initial impact at the tip of the digit results in a forceful hyperextension at the distal interphalangeal joint (DIP), resulting in the rupture of the volar capsule and dislocation of the DIP joint. Subsequently this force travels proximally and the proximal interphalangeal joint (PIP) is affected, resulting in a dislocation . Thus these dislocations occur in quick succession, rather than occurring simultaneously.…”

“…However, the patient in our case report presented following a simple fall at work. The mechanism of injury relates to a hyperextension with an element of rotatory force, first on the distal phalanx, causing a dorsal dislocation of the DIPJ, and then on the middle phalanx causing dislocation of the PIPJ 3 4. Bone avulsion and volar plate injuries have been reported 5 6.…”
