Abstract

A medical tensioning cable system provides dynamic tensioning to maintain high tension in a fixation system despite tissue shifting, cable slippage, or other inadvertent loss of tension. An exemplary embodiment of an in-line dynamic tensioning system includes a dynamically tensioning cable retainer, suitably comprising a suture anchor or bone screw, which provides a bias to maintain tension in the cable after installation. The retainer includes a retaining mechanism for retaining the cable or suture and a biasing mechanism connected to the retaining mechanism. In the event of cable slippage or slackening, the biasing mechanism tends to take up the slack and maintain tension. As a result, cable tension is maintained regardless of inadvertent cable slackening after installation.
