MCP Joint Implant Arthroplasty Stability recurring deformity loosening and tendon balancing are the primary challenges facing the design of a replacement for the MCP joint520 A common problem in MCP total joint designs has been the appropriate location of the center of rotation for the metacarpal head component5 Incorrect placement of the center of rotation hinders joint flexion and extension If the center of rotation of an MCP joint prosthesis is placed too dorsal digital extension becomes difficult but flexion is enhanced Placement of the center of rotation in a palmar direction may limit digital flexion but may enhance digital extension5 In the native joint the center of rotation of the MCP joint in relation to the metacarpal head is not fixed because the sagittal contour of the head is elliptical The movements of the normal MCP joint produce both abduction and adduction along with some rotation21 Finally threedimensional models of the hand have shown that internally transmitted compression joint forces can range to as high as six times the externally applied pinch force21 Theoretically the design of a prosthetic joint would be superior if the design closely approached the normal anatomic configuration Such a design would allow the sliding and rotational movements typically observed However shortcomings of an anatomically configured design are the potential for instability or subluxation particularly when ligamentous incompetence is present The MCP PyroCarbon Total Joint    See Answer
