Abstract
A flexible connection unit for use in a spinal fixation device, includes: a longitudinal member having first and second ends; at least one spacer located between the first and second ends, wherein the at least one spacer comprises a first portion made from a first material and a second portion made from a second material; and at least one flexible member located in a longitudinal axial channel of the at least one spacer, wherein the first and second ends substantially limit motion of the at least one spacer in the longitudinal axial direction with respect to the at least one flexible member.
Claims27
A flexible connection unit for use in a bony stabilization device, comprising:
- a first bone coupling assembly;
- a second bone coupling assembly;
- a longitudinal member including:
- a first rigid end including a surface received at least partially within and directly coupled to the first bone coupling assembly;
- a second rigid end;
- a flexible member located between the first and second rigid ends and coupled to the second rigid end;
- and
- a spacer located between the first and second rigid ends, including:
- a first part circumferentially disposed about the flexible member;
- and
- a second part circumferentially disposed about the flexible member and received at least partially within and coupled to the second bone coupling assembly, wherein the first rigid end and the flexible member are a monolith, the first part extends at least partially between the first rigid end and the second part, and the first part limits the movement of the second part about the flexible member.
