A system for repairing a defect on an articular surface of a patient's trochlear region, the system comprising a guide block comprising a body having an exterior surface configured to engage with the saddle portion and ridge portions of the patient's trochlear region, a protrusion extending generally from the body and configured to be received in a first bore formed in the articular surface along a reference axis, and a first cavity extending through the body configured to establish a first working axis displaced from the reference axis, wherein the exterior surface of the body and the protrusion are configured to secure the location of the guide block about the patient's trochlear region. A method for preparing an implant site in bone, comprising: establishing a reference axis extending from the bone; creating a bore in the bone by reaming about the reference axis; securing a guide block about the articular surface; establishing a first working axis extending from the bone using the guide block, the first working axis is displaced from the reference axis; and creating a first socket in the bone by reaming about the first working axis, wherein the first socket partially overlaps with the bore.

Devices and methods for implantation of an orthopedic device between skeletal segments using limited surgical dissection. The implanted devices are used to adjust and maintain the spatial relationship(s) of adjacent bones. Depending on the implant design, the motion between the skeletal segments may be increased, limited, modified, or completely immobilized.

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.

Disclosed is a surgical targeting device for assisting placement of an elongated guidance member in a bone. The targeting device comprises a bottom portion having a dome-shaped convex outer surface and comprising a guidance through-hole extending along a guidance through-hole central axis for receiving the guidance member. A top portion of the targeting device is configured to be gripped by a tool. Further, a surgical system is disclosed which comprises the surgical targeting device.

A tool body having a first clamp element positioned on a first tool arm and a drill guide positioned on a second tool arm. The surgical tool can also have a slider element slidable on the tool body, the slider element having a depth probe and a second clamp element. The second clamp element can be engaged with the first clamp element such that the first and second elements cooperate to define a clamp opening for receiving a supplemental screw.

A system and method for improving installation of a prosthesis. Devices include prosthesis installation tools, prosthesis assembly tools, site preparation systems, and improved power tools used in implant site preparation, the tools including a secondary motion that preferably includes an ultrasonic vibration.

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.

Methods for the prevention, or delayed onset or progression of, bone marrow edema or bone marrow lesion, and subchondral treatment to prevent the progression of osteoarthritis of a joint are disclosed. The methods involve treating the subchondral bone, while preserving, as much as possible, the joint's articular and cartilage surface. The methods could be performed before, during, or after an initial arthroscopic surgery to repair the joint. Associated devices and instruments for treatment of the subchondral bone are also disclosed.

An apparatus and a method are provided for performing cartilage allograft implant surgeries. The apparatus comprises an allograft 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.

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.
