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.

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： A fastener cartridge installs clamping fasteners, e.g., a set screw and a lock nut, to fix a linking rod or cable in the head of an anchor assembly. The cartridge carries one or more fasteners, or pairs of inner and outer fasteners, and applies them onto the anchor head without cross-threading. A separate holder mechanism aligns and guides the cartridge with a centering body into which the fastener cartridge fits. One cartridge has a box wrench that externally grips and turns the nut, and a central shaft coaxial with the box wrench that positions and rotates a clamp screw in coordination with the nut. Preferably, these are configured, by springs, detents or offset positioning surfaces, to install the inner lock screw coaxially with but ahead of the outer nut to fix a linking member anchor assemblies prior to fitting, e.g., compressions and distractions of the spine and final tightening. The holder mechanism has a distal jaw that grips the anchor head and positions the centering body on-axis, aligning it to avoid cross-threading the fasteners. The holder may have an elongated handle projecting to a side of the centering body for manipulating the holder in a surgical wound, or the holder may have a coaxially disposed and/or telescopically interfitted handle. The handle also actuates a jaw to grip the anchor head and center the assembly. Fastener cartridges may be manually gripped or turned with a wrench remote from the wound. A floating assembly enhances alignment of threads and coordination of fasteners.

摘要： A bone screw is provided having a head and a shank with opposed first and second helical threads extending there around. In one embodiment, the shank has a proximal portion with a constant minor diameter, and a distal portion with a minor diameter that decreases in a proximal-to-distal direction to form a taper. The opposed first and second helical threads preferably define a thread depth that remains constant along the length of the shank. In an exemplary embodiment, a major diameter of the shank at a distal tip of the shank is equal to or less than the minor diameter of the proximal portion of the shank.
