Abstract
A medullary-space nail to surgically treat fracture of thin, tubular bones in the human body, comprising a nail shank having a longitudinal axis and an end part at its upper end fitted for engaging a tool, a longitudinal stem and a nail tip situated at the lower end to facilitate implantation. The stem includes channels running parallel to the longitudinal axis for receiving locking wires, in such manner that the locking wires can be displaced in the channels in the longitudinal direction and beyond the nail tip and can be screwed into the bone.

A medullary-space nail for treatment of tubular bones in the human body, comprising:
- (a) a nail shank having a longitudinal axis, an upper end and a lower end, wherein,
- (b) the nail shank comprises an end part at the upper end to engage a tool, a longitudinal stem and a nail tip situated at the lower end for implantation into bone, and
- (c) the nail shank includes channels extending parallel and eccentric to the longitudinal axis for receiving locking wires, and to permit longitudinal movement of the locking wires in the channels and beyond the nail tip, wherein
- the channels define an opening along a longitudinal portion of an outside surface of the nail shank and the locking wires are retained within the channels in a direction transverse to the longitudinal axis.
A medullary-space nail for treatment of tubular bones in the human body, comprising:
- a nail shank having a longitudinal axis extending from an upper end to a lower end, wherein
- the nail shank comprises an end part at the upper end to engage a tool, a longitudinal stem and a nail tip situated at the lower end for implantation into bone, and
- the nail shank includes channels extending longitudinally through the shank and extending eccentric to the longitudinal axis;
- and
- locking wires insertable into the channels and configured and dimensioned to permit longitudinal movement therethrough, and each locking wire comprises a threaded tip, said threaded tip being displaceable beyond the nail tip and screwable into the bone to preclude rotation of the nail shank about the longitudinal axis.
