PROBLEM TO BE SOLVED: To optimize the shape, arrangement, and screw location for mounting a thigh base plate which can be used together with a posterior approach for complete hip arthroplasty using a surgical navigation system including an inertial measurement unit. I will provide a. A femoral base plate assembly comprises a plate having a bone contact surface configured to approximate the external shape of the femur, the plates being angled with respect to the bone contact surface, respectively. Includes a first plurality of openings configured to orient the fastener in a predetermined angular orientation, the plate comprises a second plurality of openings, and at least one of the second plurality of openings. Has threads, each of which extends through the bone contact surface and through the upper surface opposite the bone contact surface. [Selection diagram] FIG. 20 |
