Abstract
Embodiments herein are generally directed to fastener or fixation members, such as bone screws, for use in orthopedic stabilization assemblies. Some embodiments herein are directed to a spinal stabilization system or a method of installation of a spinal stabilization system that can include a spinal stabilization anchor including a compressible head, a distal collar separated from the head by a channel, and an elongate, longitudinally-curved shank extending therefrom. The shank further can include at least one friction member.
Claims20
A spinal stabilization system comprising:
- a fastener, a torsion shaft, a relief member, and a compression nut defining a longitudinal axis,
- the fastener comprising a post, a threaded shank extending distally from the post, and a socket,
- the torsion shaft comprising a proximal section having a tool-receiving recess and a distal section configured to be received within the socket,
- the relief member comprising a body having a bore extending longitudinally therethrough and a proximal end having a tool-receiving recess, wherein the relief member is configured to threadedly mate with the torsion shaft;
- and
- the compression nut comprising a body having a bore extending longitudinally therethrough and a proximal end having a tool-receiving recess,
- wherein the relief member is configured to be received within and at least partially threadedly mate with the compression nut,
- wherein a length of the stabilization system is variable by translating the compression nut along the longitudinal axis relative to the relief member.
A spinal stabilization system comprising:
- a fastener member comprising a head, a threaded body extending longitudinally from the head, and a socket;
- a torsion member comprising a distal section configured to be received within the socket and a proximal section comprising a tool-receiving recess;
- a relief member having a body comprising a bore extending longitudinally therethrough and a proximal end having a tool-receiving recess, wherein the bore is configured to threadedly mate with the torsion member;
- and
- a compression member having a body comprising a bore extending longitudinally therethrough and a proximal end having a tool-receiving recess, wherein the bore is configured to receive and at least partially threadedly mate with the relief member,
- wherein while assembled, each tool-receiving recess is accessible by a driver.
An assembled spinal stabilization system comprising:
- a fastener member comprising a head, a threaded body extending longitudinally from the head, and a socket;
- a torsion member comprising a distal section and a proximal section comprising a tool-receiving recess, wherein at least the distal section is disposed within the socket of the fastener member;
- a relief member comprising a body having a bore extending longitudinally therethrough, wherein the bore comprises a proximal end having a tool-receiving recess and the bore is threadedly engaged with the torsion member;
- and
- a compression member comprising a bore extending longitudinally therethrough and a proximal end having a tool-receiving recess, wherein the bore receives and is at least partially threadedly engaged with the relief member.
