ABSTRACT:
A link between members of a prosthetic limb, such as a connector between a knee joint and an elongated artificial leg member, has a frustopyramidal four-sided boss divergingly projecting from a spherically convex base which slidably engages a correspondingly concave annular socket surrounding the boss. Two pairs of set screws set 90.degree. apart in the annular socket are tightened against the sides of the frustopyramidal boss to enable its adjustment within a swing angle in two mutually orthogonal planes defining posterior-anterior positioning and lateral-medial positioning of the component parts of the prosthetic joint. The joint includes indexing means on a portion of one part visible for comparison of its angular position relative to the other part. The indexing means indicate relative position of the component parts in a plane that sets posterior-anterior position and in a separate plane that sets the lateral-medial position of the device. Further indexing means can indicate the relative rotation of one part with respect to the other part about a substantially vertical axis through the joint.
