摘要： A clamp assembly for orthopedic use having a housing that includes a top surface, a recess, a distal base and a bottom surface, the recess defining a longitudinal axis and extending through the housing from the top surface through the distal base and toward the bottom surface, and at least two through slots, each one of being disposed at a bottom or a side a surface of the housing. The assembly including a securement assembly positionable within the recess in a co-axial relationship to a mating surface on the recess, and a band sized for travel along a predetermined path defined in part by the through slots in the housing, wherein at least one of the through slots is a starting point for travel of the band along the predetermined path.

摘要： A spinal alignment system can include a rod and a plurality of uniplanar screw assemblies that include a screw, a cap, and a housing. The screw and cap can be configured such that the relative angular displacement between the screw and the cap is limited to a first limit angle in a first plane and to a second limit angle in a second plane that is perpendicular to the first plane, the second limit angle being larger than the first limit angle. The housing can be coupled to the cap and configured to maintain the cap in proximity with the head of the screw. The housing can have two elongated elements forming a U-shaped saddle. The alignment system can also include a plurality of locking cap assemblies that capture the rod within the U-shaped saddle and are tightened to fixedly couple the rod to the respective uniplanar screw assemblies.

摘要： A method for locking an elongate rod within a head of a bone anchor implant assembly that is configured for surgical implantation into a bone of a patient. The method includes providing an elongate rod, providing a separate shank and the head, and providing a closure mechanism configured as a one-part closure or two-part closure. The method further includes receiving the elongate rod in the channel and closing the channel with the closure mechanism. The one-part closure and two-part closure are configured to be interchangeable with each other for closing a channel of the head and locking the assembly and the elongate rod between arms of the head with the closure mechanism.

摘要： A bone anchor system can comprise a fastener, a rod housing and a first directional component configured for connection to the fastener. The fastener can comprise a shaft having a shaft diameter, an anchoring projection on the shaft, and a head at an end of the shaft. The rod housing can be connected to the head of the fastener. The first directional component can comprise a first body portion having a first outer diameter larger than the shaft diameter, a first bore extending through the first body portion, the first bore sized to receive the shaft diameter, and a first locking component extending from the first body portion configured to engage the rod housing to limit movement of the housing.

摘要： A receiver for engaging a bone stabilizing element includes a receiver portion connectable to the stabilizing element, and a base portion connectable to a bone of a patient. The base portion may connect to the bone with a bone screw, for example a polyaxial bone screw, and the receiver portion may connect to the stabilizing element, for example a rod, using a set screw. The receiver portion and the base portion are slideably connected to each other, coupled and constrained in relative movement, by overlapping portions. Axial rotation between the receiver portion and the base portion is enabled by changing the relative dimensions of overlapped portions.

摘要： An apparatus and method related to a collet for a spinal screw are described herein. In some embodiments, such an apparatus includes a screw, a movable head comprising a top portion and a bottom portion, a concave interior larger than a screw head, a connecting rod, a locking element screw, and a collet interposed between the screw head and the concave interior of the movable head, where the collet comprises a flexible hinge, and where the collet reduces axial compression force transferred from the set screw to the screw head.

摘要： A pivotal bone screw assembly includes a receiver having a central bore with a bottom opening and a channel for receiving an elongate rod, with the central bore including a partial spherical internal surface adjacent the bottom opening and a horizontally-extending recess with a cylindrical sidewall surface. The assembly also includes a shank with a capture structure for positioning within the central bore and an anchor portion for attachment to the bone, with the capture structure having a partial spherical lower surface configured to slidably engage the internal surface of the central bore to provide for pivotal motion of the shank with respect to the receiver, together with an insert with a rod seating surface and an outwardly-projecting radiused structure, with the insert being downwardly displaceable within the central bore until the radiused structure snaps into the recess to prevent upward movement of the insert with respect to the receiver.

摘要： A polyaxial bone anchoring device includes a receiving part with two legs defining a recess for receiving a rod and a pressure member for exerting pressure on a head of a bone anchoring element in the receiving part, the pressure member having an engagement portion. The engagement portion can extend at least partially into a leg and is directly engageable from outside the bone anchoring device to move the engagement portion axially for adjusting the pressure member from a non-locking position where the head is pivotable to a locking position where the head is clamped. When the pressure member is in the locking position and the engagement portion is free from any outside axial forces, a first contact surface of the receiving part cooperates with a second contact surface of the pressure member to hold the pressure member in the locking position.

摘要： An orthopedic fastener may include a shaft and a plurality of petals extending helically around the shaft. Each of the plurality of petals may include a proximal face and a distal face. The proximal face may include a parabolic contour formed as an undercut parabolic portion of the proximal face. The plurality of petals may be configured to generate and progressively increase an amount of compression of trabecular bone through which the petals advance during implantation in a bone, and distribute the compressive forces along a length of the shaft.
