Abstract
Abstract A surgical cable system and method for securing surgical cable around a portion of a human element (e.g., bone) is described. The surgical cable system may include a connector and a tensioner. The connector may be adapted to hold a pin, positionable within the connector, such that the pin may secure the cable within the connector. The pin may be repositioned, after securing the cable, to allow the cable to move freely through the connector. The cable may be oriented within the connector such that the ends of the cable are pependicular or parallel with respect to each other. The tensioner is preferably adapted to vary the tension of the cable. The cable may be passed through the connector, around a portion of a human bone, and back through the connector. The cable may be tensioned by use of the tensioner and secured into position within the connector.
