A nail for fixing the position and shape of broken long bones is provided. The nail has a shank having a central main body and longitudinal chamber-like expansion elements attached to the central main body which are expandable while in situ. The expansion elements run substantially the length of the shank and are preferably arranged substantially equiangularly around the central main body. When the expansion elements are expanded, a cross-section of the central main body is expanded. The central main body may be provided with channels into which the expansion elements may be disposed.
