    摘要： A method and tool for inserting a prosthetic stem component in an aligned position into a prepared bone cavity. The bone is prepared by removing bone material from the bone canal and preferably also machining an entry opening of a predetermined shape and desired orientation in the bone, or marking the plane of the joint on the bone end. The tool includes an upper component that engages the top of the prosthesis stem to fix its rotational alignment, and an arm that extends to the opening in the bone and is aligned at its distal end. The upper component rides along the arm, and orients the stem with respect to the bone as the stem is inserted. The tool may include a lower element that engages the machined or marked bone and holds the arm to orient the head of the prosthesis. Optionally, the lower element may guide the distal stem. Alternatively, the guide may include an arm that simply points to, contacts or fastens at the bone end, orienting the prosthesis insertion without sighting errors. In a pointer or pin assembly which extends to an alignment point on the proximal femur, the upper portion may clamp to the femoral component head or neck, and may include a sliding bushing, that allows the guide to remain rigidly coupled as the stem is progressively advanced in the femoral canal. Articulation may be provided by a pivot mounting of the arms and bushing, and the bushing may swivel as it rides along a post, rail or pin, the lower end of which remains pointed to, or driven into, an alignment mark scribed at the medial periphery of the cut surface of the proximal femur. Alternatively, a lower alignment body may fit against a machined bone surface to fix the orientation of a linking arm in one plane, with a sliding coupling to the upper part of the prosthesis to maintain that orientation as the stem is driven down into contact with the prepared bone surface.

    摘要： Methods and devices are provided for anchoring graft to bone. In one exemplary embodiment, a bone cavity is created in bone, a graft is partially advanced into the bone cavity, and a hardenable filler material is inserted into the cavity. The hardenable filler material can change from a viscous first state to a harder second state, compressing the graft against the walls of the bone cavity and thereby anchoring the graft within the cavity. The hardenable filler material can be inserted in an open sac, a closed sac, other carriers or housings, or directly into the bone cavity.

    摘要： An instrument for manipulating a spinal fixation element relative to a bone anchor includes a bone anchor grasping mechanism, a first adjustment mechanism, and a second adjustment mechanism. The bone anchor grasping mechanism includes a first arm having a distal end configured to engage an opening provided in the bone anchor. The first adjustment mechanism includes a second arm pivotally connected to the first arm. The second arm has a distal end configured to engage an opening provided in the bone anchor and is operable to adjust a spinal fixation element in a first direction upon pivoting relative to the first arm. The second adjustment mechanism is removably and replaceably coupled to the bone anchor grasping mechanism and is movable relative to the bone anchor grasping mechanism to adjust the spinal fixation element in a second direction, perpendicular to the first direction, relative to the bone anchor.

    摘要： A screw placement guide tool for use in minimally invasive surgery has a proximal handle portion, an extension member extending distally from the handle portion, and an alignment element connected transversely to a distal portion of the extension member and having a screw placement guide located thereon. In this aspect of the invention, the tool is configured so that a surgeon may operate the tool using the handle portion external to a patient's body to align the alignment element with implanted screws so that the screw placement guide indicates a desired position for implantation of an additional screw. Systems and methods for placing a rod receiving screw are also provided.

    摘要： An instrument for engaging a bone anchor may include a first implant engaging member having a proximal end and a distal end and a second implant engaging member having a proximal end and a distal end. The second implant engaging member may be integrally connected to the first implant engaging member by a pair of opposed integral spring members located proximal to the distal ends of the first and second implant engaging members. Manipulation of the proximal ends of the first and second implant engaging member can cause each of the distal ends to rotate about the pair of opposed spring members to engage at least a portion of a bone anchor. A rod adjusting tool may be connectable to the bone anchor engaging tool and may be axially adjustable relative to the bone anchor tool to adjust a spinal rod relative to the bone anchor.
