    摘要: Fracture reduction tool is disclosed for use with a guide wire for reducing a bone fracture. The guide wire is of a uniform diameter and has a beaded end for placement into the medullary canal. The tool includes an elongated hollow shaft which can be passed into the medullary canal of the fractured bone through an entry hole prepared in the bone. The shaft has a bore along its length through which the guide wire can selectively pass. The shaft and/or the guide wire can be manipulated into and within the respective medullary canal portions of the fractured bone by translational and/or rotational movements so as to reduce the fracture. The tool also includes a measurement sleeve which moves over the shaft and provides a determination of the length of a nail to be inserted into the medullary canal of the reduced bone. A handle for the proximal end of the shaft allows for ease in manipulation of the shaft and guide wire. Locking mechanisms to secure the measurement sleeve and guide wire in position relative to the shaft are also provided.A method of operation with the fracture reduction tool of the present invention is also disclosed.

    摘要: A femoral component (100) for a total knee joint replacement has a modular structure including a number of segments (102, 112), each of the segments (102, 112) having a femoral fixation surface (104, 114) for attachment to the distal end of a femur and at least one assembly surface (108) for joining with an adjacent segment (102, 112) of the modular femoral component (100). The assembly surfaces (108) are generally planar and arranged to be oriented generally in a plane extending in a proximal-distal direction and in an anterior-posterior direction when the femoral fixation surface (104, 114) is positioned on the distal end of the femur. Although the assembly surfaces (108) are generally planar, they may be shaped or provided with complementary structures (120) to assure self-alignment when the segments (102, 112) are assembled.

    摘要: A modular femoral internal implant system for use in the treatment of femoral disorders resulting from injury, disease or congenital defect includes at least three interconnectable components: 1) an elongated epiphyseal/metaphyseal implant, 2) an intramedullary rod and 3) an angled side plate having an elongated plate portion adapted to be secured to the outer cortical wall and a hollow sleeve adapted to extend into the femur. The epiphyseal/metaphyseal implant can be connected to either the angled side plate or the intramedullary rod. The system may also include an elongated bone plate connectable to the angled side plate, one or more additional epiphyseal/metaphyseal implants of variable length, an additional angled side plate, a distal buttress plate connectable to the elongated bone plate, and a plurality of bone screws of a universal design. Preferably, many or all of the components of the system are made of an inert, resilient titanium-base alloy.

    摘要: A method of repair of patient tissues by implant including providing a living cell sample which is introduced into an implant member having a porous open structure. The cell sample may be cultured in the implant. The implant is secured to the patient, as by surgical implantation. In one embodiment, the implant portion which receives the cells preferably has a pore size of about 25 to 75 microns. In addition, a second pore size of about 100 to 400 microns for receipt of blood vessels and osteogenus cells through ingrowth after introduction into the patient, may be provided. The cell sample may advantageously be selected from the group consisting of cartilage cells, tendon cells, ligament cells and musculotendinous cells. The implant member may be advantageously used in bone or joint reconstruction surgery and in other forms such as artificial tooth implantation.A surgical implant comprising an inert member having, in one embodiment, a first series of open pores of an average size of about 25 to 75 microns and a second series of open pores of an average size of about 100 to 400 microns with patient cells growing within the pores.
