摘要:
A flexible screw and method for non-rigid fixation between two bones. The flexible screw includes a head, and a body including a thread portion with a flexible shaft portion extending therebetween. The head has a diameter greater than that of the flexible shaft portion. The thread portion has a plurality of rigid threads while the flexible shaft portion has plurality of openings arranged in a pattern configuration. The openings extend at least partially through the flexible shaft portion. The flexible screw can be used for non-rigid fixation by inserting the thread portion in a first bone while the head is positioned on a distal side of an adjacent second bone. The flexible screw is tightened such that the flexible shaft portion extends in the joint between the first bone and the second bone. The flexible shaft portion provides stability while also adding back motility lost by the reduction in the size of the joint.
