Abstract
A fixation device adapted for use within the medullary canal of a fractured tubular bone is characterized by having a gripper unit with a plurality of outwardly concave, springy gripper fingers which can be placed under an increased force to cause the fingers to securely engage the osseous tissue surrounding the medullary canal when the device is used to maintain the fracture in compression. Force is applied to the fingers of the gripper unit by a threaded rod extending within the canal, and the rod carries a nose piece which serves both as an aid to travel of the rod through the canal and as a means for embracing the fingers of the gripper unit to disengage the fingers from the osseous tissue of the canal.
