A tibia medullary pin for the treatment of lower-leg fractures of all kinds has an anterior half (1), a posterior half (2), a proximal end segment (3), and a distal end segment (4), with the longitudinal axes (5;6) of the two end segments (3;4) forming in the antero-posterior plane an angle of 5 DEG -13 DEG with each other. The proximal end segment (3) has a cross-section area (7) that is trigonal in both the anterior (1) and the posterior (2) halves, and overall is approximately rhombic, while the distal end segment (4) has a cross-section area (8) that is approximately trigonal in the anterior half (1) and is approximately semi-spherical in the posterior half (2).
