A set of tools for installation of a stem implant into a bone comprises a stem-shaped priming tool (1) having a distal tip (32) and a plurality of cutting teeth (31) along a length thereof and a plurality of stem-shaped broaches (2, 3, 4, 5, 6) of different size. Each of the broaches have a distal tip and a plurality of cutting teeth along a length thereof. The priming tool (1) is shorter than, has more cutting teeth (31) per unit length, and has a sharper distal tip (32) than the smallest broach.

Techniques for implantable orthopedic pain management devices are disclosed, including incising an opening in a synovial capsule substantially surrounding a joint, using a first tool to form an enlarged opening in the synovial capsule, determining whether to modify the joint, the joint being modified using a second tool if a bone structure coupled to one or more bones is found within the joint and the bone structure is configured to limit articulation of the one or more bones when an implantable device is inserted into the synovial capsule and the joint, and inserting the implantable device into the synovial capsule through the enlarged opening, the implantable device being inserted into the joint using a third tool.

A novel hydraulic implant delivery system for introducing a hydrogel implant into a cartilage repair site is disclosed.

Disclosed is a device for assisting in the placement of a trapeziometacarpal prosthesis including a cup to be fixed in the trapezium of a patient and a stem to be fixed in the patient's first metacarpal. The device includes a first guide to be interposed between the trapezium and the first metacarpal, the first guide including a first body having a first surface to be positioned on the articular surface of the trapezium, the first surface congruent with the articular surface of the trapezium and a second surface to face the articular surface of the first metacarpal before resection, the second surface preferably being congruent with the articular surface of the first metacarpal so as to be positionable on the articular surface of the first metacarpal. The first guide also includes locating members carried by the first body and arranged to define resection lines for the first metacarpal.

Techniques for implantable orthopedic pain management devices are disclosed, including a body having a body configured to be disposed in a cavity between a first toroidal shape and a second toroidal shape, the body being substantially saddle-shaped and configured to have a first saddle surface aligned on a first axis and a second saddle surface aligned on a second axis, and a channel formed on the body comprising a portion of the first saddle surface and another portion of the second saddle surface.

Techniques for implantable orthopedic pain management devices are disclosed, including a saddle configured to axially align a top contoured surface to a bone surface and to axially align a bottom contoured surface to another bone surface, and a peripheral protrusion disposed on a peripheral surface of the saddle, the peripheral protrusion being configured to maintain dynamic stability of the saddle between the bone surface and the another bone surface.

Implantable orthopedic pain management devices are disclosed, including a body with a top surface having a plurality of regions, each region having a radius of curvature, and a bottom surface having another radius of curvature, the body being configured to be disposed in a joint to prevent contact between one or more bones comprising the joint, the body also not being coupled to the one or more bones, a peripheral protrusion disposed substantially about a perimeter of the body and configured to prevent expulsion of the body from the joint, and a notch disposed substantially about the perimeter of the body and formed with a region of the top surface, the notch having a substantially outward facing vertical surface that is configured to retain the device in position within the joint.
