Abstract
The artificial hand joint comprises a proximal joint part securable to the radius with a groove-like guide track and a distal joint part securable to the os capitatum with two supporting heads placed alongside one another, displaceable in the guide track in the direction of their longitudinal extent, and mounted so as to be inclinable in the transverse direction. These are executed with spherical support parts, each of which cooperates with a guidance section of the guide track. By means of the two supporting heads a stable guidance of the distal joint part in the direction of the extension movements is achieved. The guide track and the proximal joint part can be executed with advantageously small cross sectional dimensions so that the intrusions into the implantation region of the hand joint can be kept to a minimum.
