Disc and Motion Preserving Implant System

摘要

An orthopedic implant system is disclosed for use in correcting or reducing the progression of scoliosis. The orthopedic implant system can be inserted laterally or posteriorly and comprises an elongated flexible member secured to a user's spinal column via a plurality of vertebral body screws. Typically, the height of the elongated flexible member is significantly greater than the width, creating a flattened cross-sectional aspect. The vertebral body screws comprise a screw base and a screw head with a slot sized to accept an insert. Typically, the elongated flexible member is positioned within the slot via the insert, and is allowed to slide within the screw head as needed, as the user moves. However, at the apex of the user's scoliosis curve, the elongated flexible member is fixed within a vertebral body screw head.

主权项

1. An orthopedic implant system for use in correcting or resisting the progression of scoliosis curves, comprising:
a plurality of vertebral body screws each comprising a screw base and a screw head with a slot for accepting an insert; and an elongated flexible member engageable with the plurality of vertebral body screws; wherein the plurality of vertebral body screws are configured to anchor the elongated flexible member to a user's spinal column; and wherein the elongated flexible member is positioned within the slot of the screw head via the insert; and wherein the plurality of vertebral body screws comprise rotational head screws and fixed head screws; and wherein the insert is either a standard insert for rotational head screws which fully encapsulates the elongated flexible member and allows the elongated member to move or slide as needed, or a locking insert for fixed head screws which surrounds only a bottom of the elongated flexible member, and then a locking end cap with a protrusion is then threaded onto the locking insert till it contacts the elongated flexible member, holding the member in place.
