Abstract: Hip joint navigation systems and methods are provided. In some embodiments, the systems and methods described herein determine a table reference plane that approximates the Anterior Pelvic Plane. In some embodiments, the systems and methods described herein measure a pre-operative and post-operative point. In some embodiments, the comparison of the pre-operative and post-operative point corresponds to changes in leg length and joint offset. In some embodiments, the systems and methods described herein determine an Adjusted Plane. In some embodiments, the Adjusted Plane adjusts for tilt by rotating the Anterior Pelvic Plane about the inter-ASIS line. In some embodiments, the Adjusted Plane improves correlation between navigated cup angles and post-operative images.

Abstract: A femoral component instrument includes a rotatable locking mechanism such as a post and is capable of interchangeable use between posterior stabilizing (“PS”) and cruciate retaining (“CR”) femoral component types via the locking mechanism. The instrument further includes a modular pad so that a pad specific to the prosthesis type may be chosen. Each pad of a particular femoral component type is useable with a variety of sizes of that femoral component type. The locking mechanism of the instrument is alternatively useable with a variety of femoral component types. The locking end of the post keys to a pad aperture to rotatably align the post to an appropriate securement position. If a femoral component is not locked to the pad, the post of the instrument moves from an exposed position proximal to the proximal pad surface to a retracted position distal to the proximal pad surface, thereby permitting impaction.

Abstract: A tunable implant, system, and method enables a tunable implant to be adjusted within a patient. The tunable implant includes a securing mechanism to secure the implant in the patient, a actuation portion that enables the implant to move and an adjustment portion that permits adjustment of the implant after the implant has been positioned within the patient. The method of adjusting the tunable implant includes analyzing the operation of the implant, determining if any adjustments are necessary and adjusting the implant to improve implant performance. The implant system includes both the tunable implant and a telemetric system that is operable to telemetrically receive data from the tunable implant where the data is used to determine if adjustment of the tunable implant is necessary. The system also includes an instrument assembly that is used for performing spinal surgery where the instrument assembly includes a mounting platform and a jig.

Abstract: A process and system for performing orthopedic surgery to create a series of channels with a subject's bone to allow a reduced pressure system to be applied directly to the bone-implant interface to enhance bone healing is provided. The process for to promote healing of a bone of a subject includes creating a three-dimensional model of the bone; preoperatively planning a location of an implant relative to the model; creating a plan for the location of precision channels that reach the bone-implant interface based on the model and the implant; resurfacing the bone to fit the implant into or onto the bone based on the preoperative plan; and milling the precision channels into the bone in the location to promote healing of the bone and/or bone implant interface; and applying a pressure reduction system at the bone-implant interface to promote bone healing.

Abstract: The invention relates to a shaft for a femoral neck prosthesis, which comprises an anchoring area (27, 29) which is arranged inside the femur in order to anchor the prosthesis into bone, a head area which is axially adjacent to the anchoring area (27, 29) on the proximal side, said head area comprising a device (13) which is connected to the prosthesis head (15), in addition to a distal end which is arranged opposite the head area in the axial direction of the anchoring area (27, 29). The invention is characterised in that the maximum cross-sectional dimension of the head area is at the most equal and, in particular, smaller than the maximum diameter of the anchoring area (27, 29), in such a manner that the maximum cross-sectional dimension of the shaft (11) is in the anchoring area (27, 29).
