ABSTRACT:
A screw tensioning device is proposed for holding at least one end of a ligament graft. The device has a thimble (1) which locates in the mouth of a drilling through bone, a nut (2) captively seated in the thimble, and an anchorage element (3) with a screw threaded stud (12) which can engage the nut. Different forms of anchorage elements are provided for different grafts, but each is adapted to securely hold one end of a ligament graft. The anchorage element (3) with a ligament attached is drawn through the drilling from the opposite side to the thimble (1) until the stud (12) engages the nut (2). The nut is then turned by a tool (19) until the required tension is achieved.
