Cartilage Measurement Device and Method of Use
20220323239 · 2022-10-13 ·

Disclosed herein is a device that helps to reduce the potential for inaccuracies and uncertainties associated with allograft cartilage transfer procedures. In one embodiment, the disclosed device generally includes a shaft, a stationary ring attached to the shaft, and a movable ring attached to the shaft and configured to move either toward the stationary ring or away from the stationary ring along the axis of the shaft. In practice, the device may be placed within a recipient cavity and adjusted such that one ring is positioned at the distal surface of the recipient cavity and the other ring is flush with the native cartilage surface of the recipient. The device may be removed from the recipient cavity, a donor graft placed within, and any excess donor graft extending beyond the rings trimmed off. The donor graft may then be removed from the device and inserted within the recipient cavity.

Prosthesis installation and assembly
11458028 · 2022-10-04 · ·

A system and method for improving installation of a prosthesis, particularly an acetabular cup. The system and method may include implementation of a constant velocity relative motion between a prosthesis and an installation site. For example, an installation system may be fixed relative to the installation site, with the prosthesis fixed into an initial position. The prosthesis is moved at constant speed (i.e., with minimal if any acceleration or applied impulses) relative to the installation site. That is, one or both of the prosthesis or the installation site may be in motion. Resistive forces to installation of a prosthesis may thus be reduced by maintaining the prosthesis constantly in motion relative to the installation site. Securing a processing/implanting tool directly to the installation site may offer advantages.

METHODS AND TOOLS FOR HIP REPLACEMENT WITH SUPERCAPSULAR PERCUTANEOUSLY ASSISTED TOTAL HIP APPROACH
20220233335 · 2022-07-28 · ·

A minimally invasive surgical procedure for replacing a hip joint is provided. A main incision is initiated at a point being a projection of a tip of a greater trochanter and extends proximally about a distance in the range of from 1 cm to 8 cm in line with the femoral axis. An inline capsulotomy is performed, while keeping muscles and posterior capsule intact, to expose the hip joint capsule for accessing the hip joint. The femoral canal is prepared for receipt of a femoral implant. The femoral head is resected and removed out of the acetabulum. A step of acetabular preparation is performed using a retractor comprising two tip rails, each tip rail having a plurality of tines. Related tools, devices, systems and methods are also provided.

CARPOMETACARPAL (CMC) IMPLANTS AND METHODS

A surgical kit including a hydrogel implant suitable for use in a carpometacarpal joint includes an upper surface, a lower surface, and sidewalls extending between the upper surface and the lower surface, a plunger, and an introducer for depoloying the implant is provided.

GRAFT TRANSPORTATION AND IMPLANTATION SYSTEM AND METHOD FOR USE

A graft holder for securely transporting a graft, the graft holder including a base surface; and a cavity extended from the base surface and formed from one or more walls, the cavity configured so the graft is securely nested therewith when being transported between locations so as to minimize damage and/or impact to the graft during transport.

Tilting Surgical Tensor To Support At Least One Bone Cut

A surgical apparatus configured to be placed in the musculoskeletal system to precisely separate a first bone from a second bone. The surgical apparatus has one or more sensors to measure one or more parameters and supports one or more bone cuts for installing a prosthetic component. The surgical apparatus has three distraction mechanisms configured to increase or decrease a height between a first support structure and a second support structure. The tilt mechanism adjusts the tilt between the first support structure relative to the second support structure. The tilt mechanism of the surgical apparatus is adjusted from a first tilt to a second tilt to support a bone cut on one of the first or second bones.

PREOPERATIVE PLANNING AND ASSOCIATED INTRAOPERATIVE REGISTRATION FOR A SURGICAL SYSTEM

Aspects of the disclosure may involve a method of generating resection plane data for use in planning an arthroplasty procedure on a patient bone. The method may include: obtaining patient data associated with at least a portion of the patient bone, the patient data captured using a medical imaging machine; generating a three-dimensional patient bone model from the patient data, the patient bone model including a polygonal surface mesh; identifying a location of a posterior point on the polygonal surface mesh; creating a three-dimensional shape centered at or near the location; identifying a most posterior vertex of all vertices of the polygonal surface mesh that may be enclosed by the three-dimensional shape; using the most posterior vertex as a factor for determining a posterior resection depth; and generating resection data using the posterior resection depth, the resection data configured to be utilized by a navigation system during the arthroplasty procedure.
