Abstract:
Spinal fixation system connectors comprising spring cage elements. In some embodiments, an engagement member, such as a bone screw, may be configured to be coupled with and received within a connector body. A spring cage structure may also be configured to be coupled with the connector body. The spring cage structure may comprise a spring configured to be positioned in a relaxed configuration and a flexed configuration, such that the spring defines an opening having a first size in the relaxed configuration and a second, larger size in the flexed configuration to allow the opening to receive and engage a head of the engagement member within the connector body.

Claim (Index 11):
A bone screw spinal fixation system, comprising:\n a connector body configured to be coupled with a spinal fixation rod; a bone screw configured to be coupled with and received within the connector body, wherein the bone screw comprises a head having an at least partially spherical surface; a spring cage structure configured to be positioned within the connector body; and a saddle configured to be positioned within the connector body, to engage the spinal fixation rod, and to be coupled with an upper portion of the spring cage structure, wherein the spring cage structure comprises a spring having at least one helical cut extending between opposing surfaces of the spring cage structure, wherein a first helical cut extends from an opening in a bottom surface of the spring cage structure to an opening in a top surface of the spring cage structure, the spring configured to be positioned in a relaxed configuration, a flexed configuration, and a compressed configuration, wherein the spring is configured to define an at least partially spherical inner surface for receiving the head of the bone screw, the at least partially spherical inner surface having a first radius in the relaxed configuration, wherein the spring is configured to expand such that the inner surface has a second radius in the flexed configuration, wherein the second radius is larger than the first radius, and wherein the spring substantially matches and mates with the at least partially spherical surface of the head.
