Abstract
A band clamp tensioning system that includes a tensioning instrument that has a hollow body with proximal and distal ends that define a longitudinal axis, and a travel slot, a tension tightening rod disposed co-axially within the hollow body, and a carriage assembly for receiving and tensioning a band, the carriage assembly disposed co-axially within the hollow body and having a center aperture through which the tension tightening rod is inserted, and a carriage that includes at least one channel for inserting a band, and a band securing mechanism. In use the carriage moves axially between proximal and distal ends within the slot along the exterior surface of the hollow body when the tightening rod is manipulated. The system also includes a clamp housing and a band that can be tensioned around bone with the tensioning instrument and secured to the clamp housing with a locking element.
