摘要： A bone anchor assembly includes a bone anchor, a receiver member for receiving a spinal fixation element to be coupled to the bone anchor, and a closure mechanism. The closure mechanism is positionable between the arms of the receiver member to capture a spinal fixation element within the receiver member and fix the spinal fixation element with respect to the receiver member. The closure mechanism includes an outer thread engageable with an inner thread on the arms of the receiver member. The inner thread and the outer thread have a thread angle between 5° and 25°.

摘要： A polyaxial instrument suitable for preparing the intervertebral disc space of a patient through an anterior, posterior, transforaminal or anterolateral approach. The trial can be partially inserted into a disc space and then its angle adjusted to ease its further insertion into the disc space. The trial work tip can be interchangeable with the working tip of another type of instrument such as a curette, a rasp, a spreader, a shaver, a cobb elevator, a penfield, a woodson, a chisel and an osteotome.

摘要： A bone anchor assembly includes a bone anchor, a receiver member for receiving a spinal fixation element to be coupled to the bone anchor, a compression member positioned within the receiver member, and a closure mechanism including an outer set screw and an inner set screw. The outer set screw delivers a distal force to the compression member to fix the bone anchor relative to the receiver member. The proximal surface of the compression member has a shape configured to restrict deformation of the compression member arms including motion of the compression member arms relative to each other. The distal surface of the outer set screw has a shape that is complementary to the shape of the proximal surface of the compression member.

摘要： A cannulated bone anchor assembly includes a bone anchor, a receiver member for receiving a spinal fixation element to be coupled to the bone anchor, and a closure mechanism to fix the spinal fixation element with respect to the receiver member. The bone anchor includes a distal shaft having a first threaded section distal to a proximal head, a second threaded section distal to and adjacent the first threaded section, and a third threaded section distal to and adjacent the second threaded section. The first threaded section having a constant major and minor diameter. The second threaded section having a tapering major and minor diameter. The third threaded section having a tapering major diameter and a constant minor diameter.
