Dynamic spinal fixation system, method of use, and spinal fixation system attachment portions

摘要

Dynamic spinal fixation systems including a member, a first attachment portion, a second attachment portion, and an intermediate portion. The first attachment portion is attached at a superior end of the member and includes a first opening. The second attachment portion is attached at an inferior end of the member and includes a second opening. The intermediate portion connects the first and second attachment portions. The dynamic spinal fixation systems may also include a relief in at least one of the first opening and the second opening. The systems may also include a third attachment portion with a third opening and an intermediate portion with a first and a second elastic mechanism. The first elastic mechanism connects the first and third attachment portions and the second elastic mechanism connects the third and second attachment portions. Surgical methods for inserting the dynamic spinal fixation systems in a patient are also disclosed.

主权项

1. A surgical method for fusing a spine, comprising:
obtaining a dynamic spinal fixation system, comprising:
a member with a superior end and an inferior end;a first attachment portion at the superior end of the member, wherein the first attachment portion includes a first opening with a first relief;a second attachment portion at the inferior end of the member, wherein the second attachment portion includes a second opening with a second relief; andan intermediate portion connecting the first attachment portion and the second attachment portion; inserting a first bone fastener into a first vertebra of a patient and a second bone fastener into a second vertebra of the patient, wherein the first vertebra is superior the second vertebra; aligning the first relief with the first fastener and the second relief with the second fastener; moving the member into alignment with the first vertebra and the second vertebra for fixation by sliding the member along the first fastener into the first opening and along the second fastener into the second opening; and tightening the first fastener to the first vertebra and the second fastener to the second vertebra to secure the dynamic spinal fixation system to at least the first vertebra and the second vertebra of a patient's spine.
