摘要： A total hip femoral prosthesis provides a shortened neck and high porous coating level. Additionally, a means for strengthening the neck may be incorporated to increase stress transfer to the native bone. A method for reducing potential impingement that results from a high neck resection level includes cutting chamfered surfaces into the bone surrounding the proximal end of the implant. Instrumentation and methods of creating chamfered cuts are disclosed.

摘要： A bone plug removal and emplacement tool includes a cylindrical cutting element having a proximal cutting edge and a cutting tooth. The outer surface of the cutting element can include an integral shoulder (e.g., in lieu of a replaceable outer sheath) that is spaced-apart from the proximal cutting edge and that engages the surface of the bone to define a depth stop for the cutting edge. An additional cylindrical element can be disposed within the cutting element. The proximal end of that additional element, which is referred to as a "harvester," is substantially aligned with the proximal end of the cutting element to receive a plug cut from the bone. The harvester can be slidably withdrawn from the cutting element to facilitate transplating the bone plug at another location. For this purpose, a stem or plunger can be slidably inserted and moved in the harvester to dislodge the plug.

摘要： A bone plug removal tool is described. The tool includes a cylindrical cutting element having an external surface and having an internal surface defining an internal bore extending along a longitudinal axis of the cutting element from a proximal end to a distal end. A cutting tooth is located at the proximal end of the cutting element and extends into the internal bore. A replaceable outer cylindrical sheath is arranged concentrically around the external surface of the cylindrical cutting element. A bone plug emplacement tool to be used in conjunction the removal tool is also disclosed. The emplacement tool includes a cylindrical element having an internal surface defining an internal bore extending along a longitudinal axis of the element from a proximal end. The internal surface further defines an internal step adjacent a distal end of the element. A stem is disposed for co-axial movement within the element, the stem having a proximal end disposed within the internal bore. A shoulder is defined in the stem for mating engagement with the internal distal step of the element in order to limit distal movement of the stem within the internal bore. A kit incorporating the various tools is disclosed. The kit, for repair of an articular cartilage, includes the bone plug removal tool of the invention, an elongated plunger for insertion into the proximal end of the cutting element and for coaxial movement within it, the plunger for displacing a bone plug from the distal end of cutting element and the bone emplacement tool of the invention. Kits may also include a drill bit containing a depth stop. A method of repairing a defective articular cartilage is also described.

摘要： An endoscopic method and system are provided which include a guide member, or sheath, open at both ends and having a continuous opening in the sheath along its entire length. A trocar proportioned to fit within the sheath includes a prominence which fits within the opening of the sheath to provide a smooth surface on the exterior of the sheath for insertion into, for example, a hand for the endoscopic release of the carpal ligament. The trocar is removed and a videoarthroscope is inserted in one end of the sheath while a cutting instrument or other instrument is inserted in the opposite end to permit direct observation of the procedure.
