A method of and instrumentation for implanting a spherical prosthesis in a joint between a first bone and a second bone. The method includes the steps of exposing a joint between a first bone and a second bone; forming a semispherical cavity in the proximal surface of the first bone; forming a semispherical cavity in the distal surface of the second bone; and inserting a spherical prosthesis into the semispherical cavities in the proximal surface of the first bone and in the distal surface of the second bone. The instrumentation includes cutting instrument including a cutting instrument head having the shape of a segment of a sphere with at least one truncated end or side, and a shaft attached to the cutting instrument head for allowing the cutting instrument head to be inserted between the proximal end of a first bone and the distal end of a second bone, and to be then at least partially rotated about a rotational axis generally transverse to an axis or plane extending through the center of the segment of a sphere substantially perpendicular to the plane of the surface of the truncated end or side thereof. The instrumentation also includes a trial instrument with a trial instrument head having the shape of a segment of a sphere for being inserted into the semispherical cavities in the proximal end of the first bone and the distal end of the second bone.

The disclosure includes a bone plate extender and extension system. The system includes a first bone plate extender and may additionally include a bone fixation element and/or an additional bone plate. The bone plate extender may be affixed to a bone portion at one end, for instance, a fractured bone portion, via a bone fixation element, and associated with a second bone plate at an opposite end, so as to facilitate alignment and stabilization of the bone and thereby correct and treat a bone fracture. The bone plate extender may include an extended body, which includes a bone plate engagement portion, a bone fixation portion, and an intercalating portion there between. In certain variations, the extended body is planar, and in certain variations the extended body is angled, curved or arced. Methods of using such bone plate extension systems for the reduction, restoration and treatment of bone fractures are also provided.

An arthroplastic implant for a basilar joint of a hand of a patient includes a body having a distal surface and a proximal surface opposite therefrom. The distal surface is to be positioned adjacent a first metacarpal bone at the basilar joint of the hand of the patient. The arthroplastic implant also includes a shield extending outwardly from the distal surface of the body to shield adjacent portions of the first metacarpal bone and a second metacarpal bone of the hand of the patient.

A radiolucent orthopedic chuck includes a housing having a driver stem protruding from the top surface and a drill bit protruding from the underside in radially spaced relation from the driver stem so as to displace a drill secured to the driver stem from the axis of the drill bit so that fluoroscopy may be used to ensure accurate alignment of the drill bit with a hole of an intramedullary nail both prior to and during its operation. A drive train interconnects the driver stem and drill bit for rotation in unison. All parts of the chuck but for the drill bit preferably radiolucent.

An implant for the trapezium of the thumb carpometacarpal (CMC) joint comprising an integral elastomeric member configured to include a body portion having a tapered neck, having extending from one end thereof an elongated, longitudinally extending tapered portion adapted to be embedded into a reamed out-channel in the thumb metacarpal bone. After implantation, in the preferred embodiment of the method according to the invention, a segment of a nearby tendon, for example, the APL or FCR tendons, may be wrapped around the tapered neck of the implant to secure it in position, thereby forming a reinforced structure to inhibit dislocation of the prosthesis. However, in other methods, various other securing elements, including, but not limited to acellular matrices, may be used to retain the implant in position.
