Abstract: Disclosed herein is a device, and a method for using the device to measure the range-of-motion of a hip joint during a hip resurfacing surgery. The device comprises a temporary femoral component for rigidly affixing an array holder to the resurfaced femoral head to hold a primary array of tracking markers that are tracked through the range-of-motion by a computer-assisted surgical system (CASS).

Abstract: Apparatuses for mounting medical aid devices to anatomical structures and methods of use are disclosed. Mounting apparatuses may include femoral clamps or clamps configured to be affixed to other bone structures. Mounting apparatuses may include a pair of opposing arms configured to be compressed around a portion of a bone structure via a clamping force provided by a clamping assembly to affix the mounting apparatus to the bone structure. Clamping assemblies may include a magnetically-actuated clamping assembly, a mechanically-actuated clamping assembly, or a spring-actuated clamping assembly. A magnetically-actuated clamping assembly may generate a clamping force via alignment of magnetic fields within the clamping apparatus. A mechanically-actuated clamping assembly may generate a clamping force via a linkage-tensioning system, a rack-and-pinion system, or a lever-locking system.
