MCP JOINT. The metacarpophalangeal (MCP) joint most commonly dislocated is that of the thumb. A simple dislocation involves no soft tissue obstruction, and reduction should be attempted. A complex dislocation involves intervening soft tissue (i.e., ligaments, musculature, or fascia) and requires surgical reduction.CP JOINT.
