Abstract

In some embodiments, a spinal stabilization system may be formed in a patient using quick-connect sleeve assemblies. Each quick-connect sleeve assembly can be coupled to a bone fastener assembly in a fast and intuitive way. In one embodiment, a quick-connect sleeve assembly has a detachable member and a movable member. Both members engage a collar of the bone fastener assembly. In one embodiment, the engagement can be locked via one or more locking features to facilitate screwing a bone fastener of the bone fastener assembly onto a vertebral body in a minimally invasive surgical procedure. Each quick-connect sleeve assembly has a low profile and is particularly shaped for minimally invasive entry.

Claims17

Dependent claims

A method of implanting a spinal stabilization system, the comprising:

loading a first movable member into a first detachable member through at least one channel formed internal to at least a portion of a sidewall of a cylindrical body of the first detachable member;
coupling the first detachable member to a first collar of a first bone fastener assembly;
coupling the first movable member to the first detachable member causing at least one distal end of the first movable member to engage the first collar of the first bone fastener assembly to inhibit translational motion of the first collar relative to the first detachable member;
fastening the first bone fastener assembly onto a first vertebral body;
coupling a second detachable member to a second collar of a second bone fastener assembly;
coupling a second movable member to the second detachable member causing at least one distal end of the first movable member to engage the second collar of the second bone fastener assembly to inhibit translational motion of the second collar relative to the second detachable member;
fastening the second bone fastener assembly onto a second vertebral body;
and
securing a spinal stabilization rod to the first collar and the second collar to stabilize the first vertebral body and the second vertebral body.
