摘要： An apparatus for treating fractures of the femur including a screw and an intramedullary rod. The screw has a threaded portion and a smooth portion. The rod has a head, stem and a longitudinal bore. There is at least one pair of coaxial holes through the stem, transverse to the longitudinal axis of the rod, for receiving first anchoring means, such as a nail, screw or bolt, to secure the rod within the marrow canal of the femur. There are at least a proximal pair of coaxial holes and a distal pair of coaxial holes in the head of the rod in an angled direction toward the femoral head relative to the longitudinal axis of the rod. The distal pair of head holes are adapted to slidingly receive the screw to permit the threaded portion of the screw, in use, to engage the femoral head and to allow sliding compression of a femoral neck or intertrochanteric fracture. An optional second anchoring means which will also allow sliding compression and an optional set screw are also provided to adapt the fracture device to a variety of applications.

摘要： Surgical procedures, tools and implants are disclosed for both conventional and reverse shoulder implant surgeries. The improved procedures, tools and implants relate to humeral head resurfacing, humeral head resection for standard implants, humeral head resection for reverse shoulder implants, glenoid resurfacing for standard shoulder implants and glenoid resurfacing for reverse shoulder implants. 3D scans and x-rays are used to develop virtual models of the patient anatomy, identify patient specific landmarks for anchoring guide wire installation blocks, templates and drill guides. 3D scans are also used to design patient specific tools and implants for the shoulder implant procedures and to pre-operatively determine the appropriate inclination and retroversion angles.

摘要： An improved apparatus is provided to allow for an adjustable length tether for use in the spine and other parts of the body. The tether comprises an artificial strand with an eyelet formed in one end, the other end being looped through the eyelet. The other end is then secured with respect to the eyelet by a crimp, the excess length being cut off after the length of the tether has been given an appropriate tension. Alternatively, the eyelet end may be formed around a grommet. The crimp may be separate from the grommet or a part of the grommet. The mechanism by which the length is adjusted in some cases will take advantage of the shape memory properties of alloys such as nickel-titanium.

摘要： An instrument and method for guiding a spinal implant from a location outside of a patient's body to a location adjacent an exposed portion of a bone anchor engaged to the patient's spine. The instrument is a guide rod having a connecting portion and a guiding portion disposed along a longitudinal axis, with the connecting portion having a shaped end portion adapted to releasably engage a corresponding shaped end portion of the bone anchor. The guiding portion slideably engages a spinal implant and guides the implant along the longitudinal axis until the implant is positioned adjacent the exposed portion of the bone anchor for fixation thereto. The guide rod is then selectively separated or detached from the bone anchor and removed from the patient's body. In one aspect of the invention, the guiding portion is at least partially formed of a malleable material, such as aluminum or a shape-memory material, to allow the guiding portion to be bent or reshaped.

摘要： One embodiment of a spinal fixation system 10 including a pair of longitudinal members 11, 12 positionable adjacent the spine, means for engaging longitudinal members to the spine 13, 14, a pair of wedge members 16 each having a bearing surface 38 configured to bear on a longitudinal member 11, 12, and a connector 20 configured to span a distance between the longitudinal members 11, 12. The connector 20 includes a pair of engaging members 25, 26 each having a fixation surface 33 and a connecting surface 30, and a bridge member 21 attached to the connecting surfaces 30. The engaging members 25, 26 each define a thru-hole 35 for receiving one of the wedge members 16. The thru-holes 35 are aligned so that when one of the wedge members 16 is advanced through the thru-hole 35, the bearing surface 38 will bear on a corresponding longitudinal member 11, 12 to force the longitudinal member 11, 12 into contact with the fixation surface 33 and engage the longitudinal member 11, 12 to the connector 20.

摘要： A spinal implant system for correcting spinal deformities and abnormalities includes an elongated spinal rod configured to be implanted adjacent the spinal column and spanning across several vertebral levels. A number of fixation elements, such as spinal hooks, are provided for engaging vertebrae at a number of vertebral levels. At least some of the fixation elements includes an elongated stem projecting from a vertebra engaging portion. The stems of each of the fixation elements are connected to the spinal rod by way of a rod connector having a one-piece body defining a rod channel adapted to receive the spinal rod therethrough, a stem bore adapted to receive a stem therethrough, and a threaded bore. The stem bore and rod channel intersect to permit contact between the rod and the stem of a fixation element. The threaded bore intersects either the rod channel or the stem bore so that a set screw threaded into the threaded bore bears against the spinal rod or fixation element stem. As the set screw is tightened in the bore, the spinal rod and stem are clamped together to form a rigid construct. The rod channel includes a channel opening to permit top-loading of the rod connector. The fixation element stem may include external threads to receive a threaded fastener for temporarily threading onto the stem when the implant construct is at an initial posterior level above the spine. As the fastener is threaded onto the stem of each fixation element, the instrumentation is drawn down to a lower final level adjacent the vertebrae.

摘要： A tool assembly has a shaft with a sleeve slidable along it. A hexagonal drive post at the lower end of tile shaft is received in a hex socket at the upper end of a bone bolt secured in a patient's spine. A nut to secure a connector on the bolt, is temporarily stored on a short thread on the shaft near the lower end. The sleeve is slid down the shaft and a hex socket at tile lower end of tile sleeve is received on the nut. The sleeve is manually turned while a handle on a drive post at the top of the shaft prevents the shaft, and thereby the bolt, from turning. As the sleeve turns, the nut is turned off the short thread and down onto the bolt thread. A torque wrench coupled to a tool receiving surface at the top of the sleeve tightens the nut on the bolt to the specified torque while the handle on the top of the shaft prevents the bolt from turning.
