ABSTRACT:
The actabular socket supporting ring has a modular construction and is formed of a supporting ring having two securing straps for a cement-free attachment in and on the corresponding bone portions, of a socket cup which is pivotably adjustable in the supporting ring and attachable to the supporting ring by a securing element without the use of bone cement, and of an insert receiving the joint head. The modular construction, and in particular, the pivotable arrangement of the socket cup in the supporting ring, allows a biomechanically optimal alignment of the socket cup, and thus, of the insert receiving the joint ball, and the securing of the socket cup to the supporting ring by a securing element allows an entirely cement-free anchorage of all components.
