摘要： Orthopedic fixation devices and methods of installing the same. The orthopedic fixation device may include a coupling element and a bone fastener, whereby the bone fastener can be loaded into the coupling element through the bottom of a bore in the coupling element and a retention member is configured to allow polyaxial rotation of the bone fastener and also to lock the bone fastener in place upon application of a force on a saddle and clamp in the coupling element.

摘要： A method and device for inserting screws into a patient, such that when the device is removed the device does not stick to the screw. The device, being a push-off driver, may have a handle, an inner driver, and a threaded driver sleeve having a button mechanism and a plurality of spheres, and an inner sleeve. The method includes the steps of assembling a push-off driver attaching a bone screw to the push-off driver inserting the bone screw and detaching the bone screw from the driver by unthreading the threaded driver sleeve from the polyaxial screw which causes the spheres in the recess of the inner driver to back up against the start of the recess and causing the threaded driver sleeve to “push-off” the polyaxial screw from the inner driver.

摘要： A bone plate having at least one screw hole adapted to receive a bone screw, a blocker having a blocking end for blocking a bone screw from further backout of bone the blocker being predisposed in a blocking position wherein the blocking end at least partially overlaps a portion of the screw hole, the blocker being moveable from the blocking position by contact with the bone screw during insertion of the bone screw into the screw hole, and a blocker fixation element having an open orientation at which the blocker can move from the blocking position and a closed orientation preventing substantial movement of the blocker from the blocking position. The blocker fixation element cannot be moved to the closed orientation unless the screw head passes the blocker, thereby revealing that the blocker fixation element is in position to prevent substantial movement of the blocker.

摘要： A bone fixation apparatus is provided and includes a bone fixation plate having a fixation hole, a fastener shaft having a bone-anchoring portion and an upper portion defining an outer cam, and a C-shaped annular member having an outer surface, an inner surface defining an inner cam, and a gap formed through the entire annular member. The inner cam cooperates with the outer cam of the fastener shaft to move the annular member between an unexpanded position and an expanded position independent from movement of the fastener shaft relative to the bone fixation plate.

摘要： A bone plate has first and second sides, each with the same structure. The plate includes nodes separated by deformable bridges. Each node defines a screw hole, and wings extending laterally therefrom. The wings taper in thickness between the first and second sides. Screw holes are threaded into the nodes. The plate can be shaped to the bone by deformation at the bridges or removal of portions of the plate at bridges.

摘要： A screw element includes a screw axis, a shank for inserting in a bone, and a drive portion for engaging a screw driver. The drive portion includes a first wall defining a first recess and a second wall defining a second recess. Drive grooves are formed in the first wall and extend parallel to the screw axis. The second wall extends axially from a free end portion of the screw element to the first wall and has an inner diameter that continuously increases from the first wall towards the free end portion. A plurality of guide grooves are formed in the second wall at circumferential positions corresponding respectively to circumferential positions of the drive grooves. The guide grooves extend further radially from the screw axis than the drive grooves and guide the screw driver from the free end portion of the screw element to the drive grooves.

摘要： Adjustable length surgical screws and inserters for adjustable length surgical screws and methods of using the screws and inserters are provided. In general, a fixation device such as a surgical screw can be configured to have an adjustable length. The fixation device can have one or more break points along a longitudinal axis thereof. In an exemplary implementation, the fixation device can include a plurality of break points. The plurality of break points can be formed at different predetermined axial positions along the fixation device's longitudinal axis. The fixation device can be configured to break at each of its one or more break points, for example breaking along a plane that is substantially perpendicular to the longitudinal axis of the fixation device.

摘要： A driver instrument for engaging and transferring rotational torque to a bone anchor already screwed into a bony structure. The driver instrument may be advanced through an incision while disengaged from the bone anchor and thereafter engaged in a driver socket of the bone anchor. The driver instrument includes an elongate shaft extending distally from a handle, a tapered distal tip, and a driver engagement feature located proximally of the tapered distal tip. The tapered distal tip and the driver engagement feature are configured such that the longitudinal rotational axis of the driver instrument automatically moves into parallel alignment with the longitudinal rotational axis of the bone anchor as the driver engagement feature of the driver instrument is advanced into the driver socket of the bone anchor.
