ABSTRACT:
An osteosynthetic implant for setting a broken bone. The implant comprises a nail having a plurality of helically twisted blades that share a common helical axis. At least two of the blades define an angle of less than 180.degree. in a plane perpendicular to the helical axis. In a preferred embodiment, one pair of the blades of the nail is tapered towards its proximal portion and another pair has a uniform thickness. The blades are twisted by at least about 30.degree.. A cannulation runs through the center of the nail to receive a guide wire. The nail is slidably engageable to a member that is securable to an elongated portion of the bone, such as a side plate or an intramedullary nail. In a preferred implantation orientation, the proximate portion of the tapered blades is parallel to the elongated portion of the bone, and a proximate portion of the uniform blades is perpendicular thereto.
