    摘要： A sagittal approximator for clamping engagement with an open back hook for urging a spinal rod into seating engagement with said hook. The sagittal approximator includes an integral fixed handle and jaw. A shiftable handle is pivotally connected to the fixed handle. A shiftable jaw is pivotally connected to the fixed handle adjacent the fixed jaw. The pivotal handle and jaw are pivotally interconnected such that as the pivotal handle is shifted, the pivotal jaw shifts accordingly. The fixed handle includes a threaded channel and longitudinal guide rib. A spinal rod engagement head is slidably carried by the fixed handle and jaw and includes a spinal rod seat which with contact with the spinal rod produces a balanced seating load on the rod. A threaded pusher rod is carried by the channel which when rotated longitudinally shifts the head relative to the fixed handle.

    摘要： The invention provides a temporary clamp for connection to the midline clamp which holds the midline clamp in engagement about the lamina and is small enough to be substantially out of the way of the surgeon in use. The temporary clamp is removably connected to the midline clamp by a pair of screws. The temporary clamp is releasably connected to a clamp inserter such that after the midline clamp and temporary clamp is connected to the vertebra, the clamp inserted may be removed and used to connect subsequent temporary clamps. Therefore, since the clamp inserter may be removed from the surgical site without releasing the midline clamp, the surgeon may connect a plurality of the midline clamps with temporary clamps attached without significantly obstructing the surgical site.

    摘要翻译： 本发明提供了一种用于连接到中线夹具的临时夹具，其将中线夹具保持在层片附近，并且足够小以使得在使用中基本上不在外科医生的路上。 临时夹具通过一对螺钉可拆卸地连接到中线夹具。 临时夹具可释放地连接到夹具插入器，使得在中线夹具和临时夹具连接到椎骨之后，插入的夹具可以被移除并用于连接随后的临时夹具。 因此，由于夹具插入器可以在不释放中线夹具的情况下从外科手术部位移除，所以外科医生可以连接多个中线夹具并附接临时夹具，而不会明显地阻塞手术部位。

    摘要： A delivery device for an osteochondral graft comprising a tube, a plunger and a graft retention assembly is disclosed. The tube has a bore having an inside diameter and extends from a proximal end to a distal end. The inside diameter of the bore is sufficient to accept an osteochondral graft of a desired diameter. The tube has a set of apertures located adjacent the distal end of the tube. The plunger is slidably disposed within the bore of the tube. The graft retention assembly comprises a collar and a set of tabs. The graft retention assembly is attached to the tube such that the tabs are disposed within the apertures of the tube. The tabs are biased towards each other but are capable of being displaced away from each other to receive or release the osteochondral graft.

    摘要： A method and apparatus configured to strengthen and support a portion of a bone, such as the femoral head of the proximal femur, for example. The apparatus may include a housing or base member and a movable support member connected to the housing and configured to move between a first, undeployed position in which the support member is disposed proximate the housing or base such that the apparatus may be inserted into bone, and a second, deployed position in which the support member extends away from the housing or base for supporting the femoral head. The support member may be a rod, one or more wires, a leaf spring, a bladder, or an expandable mesh material, for example.

    摘要： An improved method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure which does not require incision of the quadriceps. A femoral implant in accordance with the present invention achieves intramedullary fixation as well as fixation into the femoral head to allow for the compression needed for a femoral fracture to heal. To position the femoral implant of the present invention, an incision is made along the greater trochanter. Because the greater trochanter is not circumferentially covered with muscles, the incision can be made and the wound developed through the skin and fascia to expose the greater trochanter, without incising muscle, including, e.g., the quadriceps. After exposing the greater trochanter, novel instruments of the present invention are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur. After preparation of the femoral cavity, a femoral implant in accordance with the present invention is inserted into the aforementioned cavity in the femur. The femoral implant is thereafter secured in the femur, with portions of the implant extending into and being secured within the femoral head and portions of the implant extending into and being secured within the femoral shaft.

    摘要翻译： 一种用于减少髋部骨折的改进方法和装置，其利用不需要切开四头肌的微创手术。 根据本发明的股骨植入物实现髓内固定以及固定到股骨头中以允许股骨骨折所需的压缩愈合。 为了定位本发明的股骨植入物，沿大转子进行切口。 由于大转子没有周向地被肌肉覆盖，所以可以进行切口并且通过皮肤和筋膜发生伤口以暴露大转子，而不会切开肌肉，包括例如四头肌。 在暴露大转子后，利用本发明的新型器械来制备从大转子延伸到股骨头的股骨中的空腔，并且从大转子进一步延伸到股骨的髓内管中。 在制备股骨腔之后，将根据本发明的股骨植入物插入股骨中的上述空腔中。 随后将股骨植入物固定在股骨中，其中植入物的一部分延伸到股骨头内并固定在股骨头内，并且植入物的部分延伸到并固定在股骨轴内。

    摘要： A tool and a method are provided for driving a bone pin into a fractured bone to stabilize the fractured bone by maintaining the fractured bone in a reduced state. The tool may be a handheld device including a cartridge having at least one passageway that receives the bone pin. The tool may also include a pneumatically-powered piston having a needle that is sized for receipt within the passageway of the cartridge, the needle applying sufficient force to the bone pin to drive the bone pin out of the cartridge and into the fractured bone.
