Abstract
A locking nail for treating femoral fractures has a generally cylindrical proximal portion to be positioned in the medullary canal. The proximal portion has an oblique bore for positioning and guiding a femoral neck screw. The nail has a distal portion provided with at least one cross bore for receiving a bone screw. The distal portion has an annular cross-sectional profile including an axial slot. The annular profile may be in the form of a clover leaf. A transition portion of said nail is located between the proximal and distal nail portions. The longitudinal slot extends from the transition portion to the distal tip of the distal portion.
