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.

摘要： A polyaxial bone anchor including a housing and a bone screw. A bottom surface of the housing includes an aperture that defines an angulation limit of the bone screw for each azimuthal angle around a longitudinal axis of the housing. The aperture is V-shaped, with the V-shape having converging side walls that define a low-angulation direction near their intersection and a high-angulation direction opposite the low-angulation direction. In some cases, the angulation limit of the bone screw is generally constant over a range of azimuthal angles centered around the high-angulation direction. The housing may be modular, including tabs on one component that are plastically deformed to engage a lip on another component. During assembly, a mandrel advances longitudinally along a bore in the housing, and forces the tabs radially outward toward the lip to a radially outward plastically deformed state.

摘要： An adjustable apparatus for guiding medical instruments used in attaching bone plates. The apparatus has a handle assembly, guide member, a spacer, and an actuation member. The actuation member extends from the handle assembly and actuates the spacer between a position adjacent the guide member and a position spaced from the guide member. The spacer has a through hole that may axially align with a lumen extending through the guide member when in the first position and which is moved out of axial alignment with the lumen in the second position. The spacer may function as a depth stop to control the maximum depth a drill bit can extend from the guide member.

摘要： A transverse connector for coupling between first and second elongate members of a spinal stabilization system. The transverse connector includes a connector arm, a first coupling assembly proximate a first end of the arm, and a second coupling assembly proximate a second end of the arm. The first and second coupling assemblies are secured to the connector arm through a plurality of mating engagement features, such as dovetail grooves.
