Abstract
Abstract A device for stabilizing a long bone combines an external fixator with a locking nail implanted in the medullary canal of a long bone. The external fixator has fixed bone pins at each of its ends and movable bone pins intermediate its ends. The fixed bone pins extend through transverse bores at each end of the bone nail and the movable pins extends through a slot in the bone nail intermediate its ends. By this method a fracture can be compressed and stabilized while healing.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
A device for stabilizing long bones comprising: an external fixator comprising a longitudinally extending support rod to be spaced from and parallel to said long bone, at least three pins transversely mounted in series to said support rod along the length thereof, at least one of said pins located on said support rod intermediate two of said at least three pins being movable in a longitudinal direction; and a locking nail for mounting in the medullary canal of said long bone which has at each of its ends at least one transverse through bore for receiving at least one of said at least two pins, and having between the ends of said nail at least one elongated longitudinally extending transverse through slot for receiving said at least one movable pin.
Claim 2
Independent Claim
130 words
A device for stabilizing long bones comprising: an external fixator comprising a longitudinally extending support rod to be spaced from and parallel to said long bone, at least three pins transversely mounted in series to said support rod along the length thereof, at least one of said pins located on said support rod intermediate two of said at least three pins being movable in a longitudinal direction; and a locking nail for mounting in the medullary canal of said long bone which has at each of its ends at least one transverse through bore for receiving at least one of said at least two pins, and having between the ends of said nail at least one elongated longitudinally extending transverse through slot for receiving said at least one movable pin.
Claim 3
Dependent Claim
35 words
The locking nail of claim 1 wherein said at least one elongated slot includes two transverse slots provided adjacent the ends of said nail, said slots separated from each other by a solid nail portion.
Claim 4
Dependent Claim
29 words
The locking nail of claim 1 wherein said through bores and said at least one elongated slots through said nail extend transversely through said nail parallel to each other.
Claim 5
Dependent Claim
32 words
The locking nail of claim 3 wherein said locking nail has a hollow body which comprises a circumferentially extending wall and said slot extends through opposite sides of said circumferentially extending wall.
Claim 6
Dependent Claim
52 words
The device of claim 1 wherein said two of said at least three pins are in a fixed position on said rod and extend through holes in said rod, said at least one movable pin is mounted on said support rod and extends through said elongated longitudinal slot in said locking nail.
Claim 7
Dependent Claim
25 words
The device of claim 1 wherein at least one of said at least two pins are fixed with respect to said longitudinally extending support rod.
Claim 8
Dependent Claim
21 words
The device of claim 1 wherein each of said at least two pins are fixed to said longitudinally extending support rod.
Claim 9
Dependent Claim
15 words
The device of claim 1 wherein said longitudinally extending support rod has a threaded portion.
Claim 10
Dependent Claim
43 words
The device of claim 8 wherein said at least one moveable pin is mounted on a threaded support element operatively engaging said threaded portion so that rotation of said support rod causes movement of said pin between said at least two fixed pins.
