Abstract
A semi-rigid, fixation device includes a rigid anchor portion configured to be directly rotated and driven distally into a first bone or bone portion of a patient. The device includes a rigid cap portion configured to be held in tension against at least one of a bone plate and a second bone or bone portion of the patient and indirectly rotated under torque provided by the anchor portion. The device includes a flexible member including a plurality of woven stands and having a fixed length between first and second ends, which are fixedly respectively coupled to the anchor portion and cap portion, such that a torque provided by the direct rotation of the anchor portion is transferred through the flexible member to the cap portion when the flexible member is held in at least a first amount of longitudinal tension. Methods of use and manufacture are also provided.
