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 nail of the set of nails having a different length in which the intermediate opening is the same distance from the proximal end for each nail.

Claims (38)

1. A method of treating a bone fracture comprising:

inserting a nail into an intramedullary canal,

wherein the nail comprises a distal area, a medial area, a proximal area, a transition portion, and a diameter taken in a plane perpendicular to a longitudinal axis of the nail,

wherein a head portion of the nail comprises the proximal area,

wherein a stem portion of the nail comprises the medial area and the distal area,

wherein only two openings in the head portion extend transverse to the longitudinal axis of the nail, each of the only two openings have an axis that extends transverse to the longitudinal axis of the nail, and the axes are parallel,

wherein a single opening in the medial area extends transverse to the longitudinal axis of the nail and is distal to the only two openings in the head portion,

wherein there are no openings in the distal area extending transverse to the longitudinal axis of the nail, and a distal one-half of the nail is free of an opening;

wherein the nail extends substantially an entire length of the intramedullary canal,

wherein the head portion has a larger diameter, the stem portion has a smaller diameter, and the transition portion tapers from the head portion to the stem portion,

wherein a fitting is disposed on the head portion at a proximal end of the nail, and the fitting is configured for receiving a tool for manipulating the nail,

wherein the nail comprises a distal end and a throughbore extending from the proximal end to the distal end along the longitudinal axis;

inserting a first anchoring member into the only two openings in the head portion; and

inserting a second anchoring member into the opening in the stem portion.

2. The method of claim 1 , wherein the first anchoring member and the second anchoring member are bone screws.

3. The method of claim 1 , wherein the intramedullary canal is a femoral intramedullary canal.

4. The method of claim 1 , wherein the only two openings in the head portion comprises two openings.

5. The method of claim 1 , wherein a distal two-thirds of the nail is free of an opening.

6. The method of claim 1 , wherein the nail includes a bend.

7. The method of claim 6 , wherein the bend separates the body of the nail into a first portion that is substantially straight and a second portion that is substantially straight, and the first portion has the longitudinal axis and the second portion has a second longitudinal axis, and the longitudinal axis and the second longitudinal axis are non-parallel.

8. The method of claim 1 , wherein the single opening in the medial area has another axis that extends transverse to the longitudinal axis of the nail, and the another axis of the single opening in the medial area and the axes of the only two openings in the head portion are non-parallel.

9. The method of claim 1 , wherein the nail is substantially straight.

10. The method of claim 1 , wherein the axes are non-perpendicular to the longitudinal axis.

11. The method of claim 1 , wherein a distal two-thirds of the nail is free of an opening, the single opening in the medial area has another axis that extends transverse to the longitudinal axis of the nail, and the another axis of the single opening in the medial area and the axes of the only two openings in the head portion are non-parallel to each other and non-perpendicular to the longitudinal axis.

12. A method of treating a bone fracture comprising:

inserting a nail into an intramedullary canal,

wherein the nail comprises a distal area, a medial area, a proximal area, a transition portion, and a diameter taken in a plane perpendicular to a longitudinal axis of the nail,

wherein a head portion of the nail comprises the proximal area,

wherein a stem portion of the nail comprises the medial area and the distal area,

wherein only two openings in the head portion extend transverse to the longitudinal axis of the nail,

wherein a single opening in the medial area extends transverse to the longitudinal axis of the nail and is distal to the only two openings in the head portion,

wherein there are no openings in the distal area, and a distal one-half of the nail is free of an opening;

wherein the nail extends substantially an entire length of the intramedullary canal,

wherein each of the distal area, the medial area, and the proximal area are about one-third of the entire length of the nail;

wherein the head portion has a larger diameter, the stem portion has a smaller diameter, and the transition portion tapers from the head portion to the stem portion,

wherein a fitting is disposed on the head portion at a proximal end of the nail, and the fitting is configured for receiving a tool for manipulating the nail;

inserting a first anchoring member into the only two openings in the head portion; and

inserting a second anchoring member into the opening in the stem portion.
