1. A cerclage cable tensioner comprising:
a body comprising a shaft having a proximal end and a distal end;
a modular tip disposed at the distal end of the shaft and removably affixed thereto;
a cam lock lever disposed adjacent to the modular tip, wherein the cam lock lever controls the locking and unlocking of the cam lock, wherein the cam lock acts on the cerclage cable;
a manually rotatable rotary actuator threadably disposed toward the proximal end of the shaft, wherein the rotary actuator is manually rotatable in opposite directions by a user, wherein one direction displaces a threaded cylinder to apply tension to the cerclage cable, and wherein the opposite direction retracts the threaded cylinder, thereby decreasing tension to the cerclage cable;
a squeeze actuator coupled to a linkage, wherein the linkage drives a central shaft forward to apply tension to the cerclage cable, such that both the manually rotatable rotary actuator and the squeeze actuator are configured to apply tension to the cerclage cable;
a tension release trigger, wherein tension release trigger releases a pawl that prevents the central shaft from moving in one direction and thereby releases tension from the squeeze actuator; and
a rear cam lock disposed at the proximal end of the shaft, wherein the rear cam lock secures the cerclage cable in the cerclage cable tensioner;
wherein a cerclage cable is threaded through the shaft from the modular tip at the distal end and through the proximal end of the shaft.
