Abstract
Official abstract text for this publication.
A system for interconnecting bones includes an implantable member configured to be mechanically coupled to a first bone, configured to be mechanically coupled to a second bone, configured to provide substantially no resistance to compression of the implantable member, configured to support a tensile load within a predetermined range of tensile loads extending from a first load to a second load, configured to have a predetermined elasticity within the range of tensile loads, configured to have a first characteristic at the first load, and configured to have a second characteristic at the second load. The system also includes a means for measuring the first characteristic and the second characteristic. And the system includes a means for calculating a tension between the first bone and the second bone based on the first characteristic and the second characteristic.
First claim
Opening claim text (preview).
What is claimed is: 1 . A system for interconnecting bones, the system comprising: an implantable member configured to be mechanically coupled to a first bone, configured to be mechanically coupled to a second bone, configured to provide substantially no resistance to compression of the implantable member, configured to support a tensile load within a predetermined range of tensile loads extending from a first load to a second load, configured to have a predetermined elasticity within the range of tensile loads, configured to have a first characteristic at the first load, and configured to have a second characteristic at the second load; a means for measuring the first characteristic and the second characteristic; and a means for calculating a tension between the first bone and the second bone based on the first characteristic and the second characteristic. 2 . The system of claim 1 , wherein the first characteristic is a first width, and wherein the second characteristic is a second width. 3 . The system of claim 1 , wherein the first characteristic is a first opacity, and wherein the second characteristic is a second opacity. 4 . The system of claim 1 , wherein the first characteristic is a first magnetic force-displacement, and wherein the second characteristic is a second magnetic force-displacement. 5 . A method for applying a tension force between a pair of bone anchors, the method comprising the steps of: attaching a first bone anchor to a first vertebra; attaching a second bone anchor to a second vertebra; attaching a first portion of a flexible member to the first bone anchor; attaching a second portion of the flexible member to the second bone anchor such that there is slack in the middle portion of the flexible member between the first and second portions; reducing the length of the middle portion and removing the slack; measuring the size of a feature of the middle portion after said removing; tensioning the middle portion after said measuring; remeasuring the size of the feature of the middle portion after said tensioning; and comparing the measured size to the remeasured size and determining the state of tension in the middle portion.
