ABSTRACT:
Apparatus and methods are provided to allow attachment of one or more surgical cables in the form of a loop to selected portions of a patient's body. The apparatus includes a cable tensioner which applies manual force to the surgical cable at a one to one ratio during installation. The cable tensioner includes a first handle fixed to one end of an elongated shaft and a second handle which is slidably disposed on the exterior of the elongated shaft. The second handle may include a unidirectional paw to allow movement of the second handle in only one direction towards the fixed handle. During the installation of two or more surgical cables, a tensioner may be engaged with each cable to allow the surgeon to alternately tighten and/or loosen the associated cable as required to provide the optimum mechanical support for the bones or other portions of the patient's body which are engaged by the respective surgical cable loops. The elongated shaft may be modified to accommodate the use of various crimps and locks to securely engage a loop in the cable after the desired tension has been placed on the surgical cable.
