Abstract
A bone screw for Charcot foot includes a non-threaded intermediate portion between threaded tip and head portions. The intermediate portion is longer than the tip and head portions. The head portion has an outer diameter larger than the intermediate and tip portions. The screw includes at least one transverse hole on the intermediate portion with a circular cross-section which is arranged for inserting a pin to prevent migration of the screw. The screw includes a helical groove on the intermediate portion. The head portion is removably coupled to the intermediate portion by a shape coupling between two profiles which allows only one relative coupling orientation or at least two relative coupling orientations rotated by a specific angular distance with respect to each other. The head portion is coupled to the intermediate portion by a shape coupling between two profiles comprising a radial groove and a radial relief.
