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.

An apparatus and a method are provided for performing cartilage graft implant surgeries. The apparatus comprises a graft plug kit comprising one or more grafts configured to treat osteochondral defects in various bone joint locations in a patient's body. Each of the grafts comprises a cartilage layer coupled with a bone portion. The cartilage layer comprises a thickness selected to closely match the thickness of existing cartilage at an implant location. The bone portion comprises surface features configured to encourage the patient's bone tissue to grow into the bone portion, thereby accelerating incorporation of the graft into the patient's bone. An instrument kit comprises a multiplicity of instruments configured for implantation of the grafts into the patient's body, including at least a graft inserter, a guidewire, a reamer, and a size gauge.

A modular femoral prosthesis for use during performance of a hip revision procedure includes a proximal body component, a distal stem component, and a locking bolt. Surgical instruments and methods for use in implanting such a modular femoral prosthesis are disclosed.

Implants 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. The implant includes hydrogel material such as polyvinyl alcohol (PVA) hydrogel. Kits can include systems for preparing an implantation site, creating a cavity, and/or deploying the implant. Methods of treating a carpometacarpal joint include deploying an implant in a recess in a carpometacarpal bone.

An implant for repairing an articular cartilage defect site including an implant fixation portion with an upper segment and at least one bone interfacing segment and a top articulating portion with an articulating surface and an engagement surface. The upper segment includes a supporting plate with a first locking mechanism segment. The engagement surface includes a second locking mechanism segment. The first locking mechanism segment with at least two channels is structured to couple to the second locking mechanism segment with at least two protrusions. The at least one bone interfacing segment structured for insertion into the articular cartilage defect site. An implant including an implant fixation portion, a top articulating portion, and a locking mechanism with a first locking segment coupled to the upper segment and a second locking segment coupled to the at least one engagement surface and structured to couple to the first locking segment.

Surgical instrumentation may be used to insert a spinal implant into a vertebral space while in a contracted condition and then deploy the spinal implant into an expanded condition.

Embodiments of devices, apparatuses, kits, and methods for repairing a human joint by suturing biological tissue to the articular surface of a bone at the joint (e.g., repairing defects in the humerus at the glenoid joint after an anterior shoulder dislocation) are described herein. Biological tissue may include hard tissue such as bone or a joint socket or soft tissue such as cartilage, ligaments, tendons, or muscle tissue.

A drill tool for implant surgery including a first drill part having a first, smaller diameter for drilling a recess for an implant post and a second drill part having a second, larger diameter for drilling a recess for an implant hat is disclosed. The second drill part has one or more shape cutting edges and one or more sharp pre-cutting edges extending beyond said one or more shape cutting edges.
