Abstract
Abstract The invention is a method and tool used for the setting of fractured bones. In detail, the tool comprises an elongated, cylindrical rod having an axial bore. A T-shaped handle is removably fixed to one end of the rod to permit manual manipulation thereof. In the setting procedure the elongated rod is inserted into the medullary canal after it has been reamed. Manual manipulation of the rod aligns the fragments of the bone. After the bone fragments have been aligned a guide wire is passed through the bore of the rod and the rod is removed leaving the guide wire across the fracture.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
202 words
A method of setting fractured long bones, having a central medullary canal, of a limb while the limb is under at least periodic X-ray observation comprising the steps of: placing the limb in traction; making an opening from the exterior of the limb to the intermedullary canal of the bone through one end thereof; inserting a guide wire through said opening into the canal at the point of fracture; reaming the canal to the point of fracture by means of a hollow reamer guided by said wire; removing said reamer and said guide wire from the limb; inserting an aligning tool in said reamed portion of the canal through said aligned opening to the point of the fracture, said aligning tool having a passageway therethrough; leveraging said tool to align the reamed portion of the bone with the unreamed portion of the bone using X-ray exposures as a guide; inserting a second guide wire through said reamed portion and the remaining unreamed portion of the bone; reaming the second portion of the bone by means of said hollower reamer guided by said second guide wire; removing said reamer; installing a hollow pin in said aligned canal; and withdrawing said second guide wire.
Claim 2
Independent Claim
202 words
A method of setting fractured long bones, having a central medullary canal, of a limb while the limb is under at least periodic X-ray observation comprising the steps of: placing the limb in traction; making an opening from the exterior of the limb to the intermedullary canal of the bone through one end thereof; inserting a guide wire through said opening into the canal at the point of fracture; reaming the canal to the point of fracture by means of a hollow reamer guided by said wire; removing said reamer and said guide wire from the limb; inserting an aligning tool in said reamed portion of the canal through said aligned opening to the point of the fracture, said aligning tool having a passageway therethrough; leveraging said tool to align the reamed portion of the bone with the unreamed portion of the bone using X-ray exposures as a guide; inserting a second guide wire through said reamed portion and the remaining unreamed portion of the bone; reaming the second portion of the bone by means of said hollower reamer guided by said second guide wire; removing said reamer; installing a hollow pin in said aligned canal; and withdrawing said second guide wire.
Claim 3
Dependent Claim
17 words
The tool as set forth in claim 1, wherein the opposite end of said rod is pointed.
Claim 4
Dependent Claim
52 words
The method as set forth in claim 1 where said tool comprises: an elongated, cylindrical rod having an axial bore therethrough, said rod having a diameter only just sufficiently smaller than the diameter of the reamer used to ream the hole; and a handle means mounted to one end of said rod.
Claim 5
Dependent Claim
31 words
The method as set forth in claim 3, including said rod having a length sufficiently long so as to reach the point of fracture from a point external of the limb.
Claim 6
Dependent Claim
85 words
The method as set forth in claim 4 wherein said tool further comprises: said opposite end of said rod is externally threaded; and said handle means comprising; a shaft having first and second ends and an internal bore therethrough, said second end having internal threads adapted to receive said threaded one end of said rod portion when inserted from said first end thereof; and a handle comprising a bar mounted at its middle portion to said second end of said shaft at right angles thereto.
