Abstract

A trochanteric nail for insertion in an intramedullary canal of a bone for treating bone fractures. The nail may include an elongate body having a head portion and a stem portion. One or more openings may be provided in the head portion for receiving an anchoring member, such as a bone screw, for fastening the nail within the bone. An intermediate opening may also be provided in the stem portion for receiving an anchoring member. A distal area of the nail may include or be free from anchoring members. In addition, a set of nails may be provided with each of the nails of the set of nails having different length in which the intermediate opening is the same distance from the proximal end for each of the nails.

Claims (20)

1. A method of treating a fracture in a bone includes the steps of:

providing a plurality of nails with each nail having a different overall length, each nail having a proximal end, a distal end, a head portion and a stem portion, and a transition portion between the head portion and the stem portion, the head portion having an opening and the stem portion having an opening, each nail having a uniform distance from the proximal end to the opening in the stem portion;

selecting a nail from the plurality of nails and inserting the nail into the bone;

inserting a bone screw into the opening in the head portion;

inserting a bone screw into the opening in the stem portion; and

maintaining at least a lower third of the nail free from an anchoring member.

2. The method of treating a fracture in a bone as set forth in claim 1 including the step of maintaining a least a lower half of the nail free from an anchoring member.

3. The method of treating a fracture in a bone as set forth in claim 1 including the step of maintaining at least a lower two-thirds of the nail free from an anchoring member.

4. A nail system for treating a fracture in a bone comprising:

a plurality of nails having different longitudinal lengths;

each of said nails having an elongate body extending between a proximal end and a distal end, said body including a proximal area, a medial area and a distal area, a longitudinal axis extending between said proximal end located in said proximal area of said elongate body and said distal end located in said distal area of said elongate body, a head portion located in said proximal area and a stem portion located in said medial area and said distal area; said head portion having at least one opening extending transverse said longitudinal axis through said head portion and said stem portion free of openings in said distal area at said distal end; and

said stem portion having an intermediate opening formed in said medial area wherein a distance from the proximal end to the intermediate opening is the same for each nail of the plurality of nails irrespective of the longitudinal length of each nail.

5. A nail for treating a fracture in a bone comprising:

an elongate body configured to extend a substantial entire length of the bone, the elongate body having a longitudinal axis and extending between a proximal end and a distal end, wherein said elongate body includes a distal area, a medial area and a proximal area each of said distal area, medial area and proximal area representing one-third of the overall length of the elongate body;

a head portion located in the proximal area, said head portion having a head diameter;

a stem portion located in the distal area and the medial area, said stem portion having a stem diameter, wherein the head diameter is greater than the stem diameter;

said stem portion having an intermediate opening in the medial area, said stem diameter adjacent said intermediate opening different than said head diameter, said intermediate opening extending transverse said longitudinal axis of said elongate body;

a transition portion located adjacent said head portion;

at least a lower half of the nail free from an opening for receiving an anchoring member; and

said intermediate opening longitudinally spaced from said transition portion and adjacent said lower half of said nail.
