Title:
A SPINAL ROD TRANSLATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/118348
Kind Code:
A3
Abstract:
A rod translation device is described that minimizes the wear between a spinal rod and a bone anchor in a spinal implant. In one embodiment, the rod translation device is a sleeve that is slid onto the outside diameter of the spinal rod. At least one compressible member, such as an O-ring, may be placed within the inside diameter of the sleeve to prevent direct contact of the outside diameter of the spinal rod to the inside diameter of the sleeve. Once the spinal rod is secured within the implant any translation of the spinal rod decreases wear debris between the outside diameter of the spinal rod and the pedicle screw.
