Abstract

A hollow elongated medullary bone nail capable of being locked in place with at least a pair of transversely-disposed bone screws is disclosed. The radius in transverse cross-section of the outer surface of the nail varies over the circumference of the cross-sectional profile of the nail in such a manner that a steadily rounded contour results.
