No prosthesis yet designed for replacement of the metacarpophalangeal (MCP) joint
incorporates all considerations of anatomy and geometry of the natural joint to restore
the normal kinematics. Loss of stability, recurrent deformity, and early loosening
are persistent problems. In this study, a detailed three-dimensional geometric analysis
of the MCP joint was performed. The sagittal contours of both metacarpal heads and
base of the proximal phalanx under loaded and unloaded conditions were analyzed. The
geometric parameters of the MCP joint articulating surfaces were analyzed, including
the center and radius of curvature and the location and size of the contact area.
The pressures on articulating surfaces during various hand functions were also established.
These findings provided important information for better understanding the kinematics
of finger joint articulation, as well as the cause of joint degeneration.
