Abstract: Methods, devices, and kits include an orthopedic screw that is configured to be at least partially withdrawn from bone segment(s) and has, in part, a shaft extending from a distal end to a proximal end, screw threads with a first threaded alignment formed on the distal end, an unthreaded shank, a head positioned on the proximal end, and an enlarged terminal end segment of the head that includes (1) a socket for receiving a tool adapted for rotating the screw into the bone segment(s), and (2) a threaded cannula portion centrally located at a focus point of the enlarged terminal end and extending along a cannula for at least a portion of a length of the head comprising a second threaded alignment opposite the first threaded alignment and configured to receive an instrument head.

Abstract: A method of using a screw for reducing a malleolus bone fracture. The orthopedic screw includes a unitary shaft with screw threads on a distal end of the shaft and a head on a proximal end. An enlarged terminal end segment of the head includes a socket for receiving a tool adapted for rotating the screw into aligned fibula and malleolus bone fragments at the fracture site. First and second spaced-apart tapered transition segments are formed at a juncture of the shaft and head and a juncture of the head and an enlarged terminal end segment of the head the such that rotation of the screw provides progressively increased fracture-reducing pressure between the fibula and malleolus bone fragments as the first and second tapered transition segments drives the malleolus against the fibula.

A method of using the screw for reducing a malleolus bone fracture is also disclosed.

Abstract: An orthopedic screw that includes a screw shaft having a predetermined length with a cannula extending through the length of the shaft. The shaft includes a first, relatively large outside diameter proximal segment; and a second, relatively small outside diameter threaded distal segment adjacent the proximal segment.
