摘要： The present application is directed to set screws used with fasteners to capture and engage an elongated member. The set screws include a body sized to attach to a receiver of the fastener. A deformable member may be attached to an end of the set screw and provides for the set screw to more fully engage the elongated member to prevent potential damage to the elongated member and prevent the set screw from backing out of the fastener. In one embodiment, just the deformable member contacts the elongated member. In another embodiment, the deformable member and the body contact the elongated member. In yet another embodiment, a contact member is attached to the deformable member to contact against the elongated member.

摘要： The present application is directed to embodiments of a pedicle screw assembly to position an elongated member within a patient. The assembly may include a receiver with a channel sized to receive the elongated member and a chamber. The assembly may also include an anchor with a head sized to fit within the chamber. The assembly may include a compression member sized to fit within the chamber and include a first side that contacts against the head and a second side that contacts against the receiver. At least one of the receiver, anchor, and compression member may be constructed of a first material, and at least one of the receiver, anchor, and compression member may be constructed of a second material. The first and second materials may include different moduli of elasticity to prevent deformation of the assembly.
