Abstract: A tension device for applying tension to an orthopedic cable loop system is designed to remain implanted in vivo after completion of the surgical procedure in which the device is used. The tension device may include a spool rotatable in one direction, such as by having outer flanges engageable with ratcheting protrusions along a cavity within the body of the device. The tension device may maintain a biasing force on the cable, which force may be applied by an elastic material. For example, the elastic may be provided in an opening of the body of the device. In another example, the elastic may be provided in the spool, such as by constructing the flanges of the spool from elastic material or by providing elastic material between an inner and an outer ring of the spool. Other biasing components as well as measuring components may be provided in the tension device.

Abstract: Disclosed herein are cable plugs for securing surgical cable to a bone plate. The cable plugs each have a cable retaining member and a fastening member. The cable retaining members each have a receiving portion adapted to receive a portion of the surgical cable therein. The cable retaining members are first coupled to the fastening members prior to securing the cable plug to the bone plate. The cable retaining member may rotate with respect to the fastening member about 270° along a longitudinal axis of the cable plug when the cable retaining member is coupled to the fastening member. When securing the surgical cable to the bone plate, the cable retaining member is rotated about the longitudinal axis of the cable plug until an axis of the receiving portion is parallel to an axis of the surgical cable. The surgical cable is then placed within the receiving portion, tightened, and crimped to secure the bone plate to the bone.

Abstract: A medical system includes parts used in a method for detachably establishing a spatial orientation between a body implant and an aiming device. A positioning arm being connected to the aiming device and an adaptor device being connected to or integrally formed with a bone stabilizing plate are hooked into each other. This is accomplished by means of an engaging element of the positioning arm, which engaging element is designed such that it may be coupled with an attachment element of the adaptor device. Further, there is provided a snapping mechanism which is designed to automatically engage in an interlocking element of the adaptor device, when the positioning arm, when hooked into the adaptor device, is rotated relative to the adaptor device towards a final angular position.
