ABSTRACT:
A cerclage cable system comprises a cable in conjunction with a biasing mechanism for maintaining cable tension. Inadvertent loss of cable tension is compensated for by the biasing mechanism. In one embodiment, cerclage cable system includes a leaf spring disposed between the cable and the bone. Alternative embodiments include other biasing mechanisms, such as helical compression springs and resilient materials. Further embodiments include biasing mechanisms in line with the cable to maintain tension. Such a cerclage system maintains cable tension by taking up inadvertent slack in the cable with the biasing mechanism.
