We present the results of 26 patients with 31 consecutive displaced or unstable extra-articular fractures of the base and shaft of the proximal and middle phalanges of the digits of the hand, treated over a period of 12 months with an intramedullary headless compression screw and early mobilization with no splinting. All fractures healed with no major complications. Only one patient, who had a pathological fracture through an enchondroma, required a tenolysis to improve the mobility of the finger. This technique seems to be technically simple, effective and with few drawbacks. IV.
