A screw device for the coaptation of two small bone fragments includes a threaded proximal head part and a threaded distal part, the proximal part having a diameter greater than the distal part and having a thread pitch smaller than that of the distal part. The distal part is threaded over substantially its entire length and a short length smooth portion is provided between the proximal and distal parts. The upper edges of the threads of the two threaded parts are perpendicular to the axis of the thread, while their lower edges are oblique, and each threaded part has at its base at least one tapping notch. An axial channel is provided in the screw for permitting the use of a guide pin.

Abstract

A screw device for the coaptation of two small bone fragments includes a threaded proximal head part and a threaded distal part, the proximal part having a diameter greater than the distal part and having a thread pitch smaller than that of the distal part. The distal part is threaded over substantially its entire length and a short length smooth portion is provided between the proximal and distal parts. The upper edges of the threads of the two threaded parts are perpendicular to the axis of the thread, while their lower edges are oblique, and each threaded part has at its base at least one tapping notch. An axial channel is provided in the screw for permitting the use of a guide pin.
