Abstract
An apparatus for adjustably positioning an extremity or body part such as knees, hands, or feet for a surgical procedure comprising a carriage including a base adapted to engage a track for selective positioning there along, an arm configured to pivotably attach to the base, and a socket formed by the joining of the base and arm, the socket configured to accept a ball of an extremity holder. The apparatus further comprises a clamping assembly and an adjustable cross nut assembly. The adjustable cross nut assembly provides clocking and/or adjustable positioning of an internal thread start to provide optimal positioning of the handle that achieves the clamping effect, as the threads are subject to wear and plastic deformation due to use over time.
