Abstract
Abstract A method of setting fractures of a limb which comprises applying tension to the ends of the limb which is fractured while the limb is under X ray observation, engaging portions of the limb with hooks of tools grasped out of the range of the X ray exposure, moving the hooks transversely to manipulate the portions of the limb while the portions are under X ray observation to align the portions of the limb, and inserting a wire axially through the aligned portions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
154 words
In the method of setting fractures of a limb which comprises applying tension to the ends of the limb which is fractured while the limb is under X ray observation, manually manipulating the portions of the limb while it is under X ray observation to align the broken portions, and inserting a wire axially through the aligned portions, the improvement comprising externally engaging a first portion of the limb adjacent the fracture with a first tool having a hook sufficiently larger to encircle the first portion, externally engaging a second portion of the limb adjacent the fracture with a second tool having a hook sufficiently larger to encircle the second portion, manipulating the portions of the limb by grasping the tools out of the range of the X ray exposure and moving the tools transversely to manipulate the portions of the limb to align the broken portions so that the wire can be inserted.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
26 words
The method set forth in claim 1 wherein each tool includes a handle connected thereto and the step of manipulating is accomplished by grasping said handles.
Claim 4
Dependent Claim
100 words
A tool means for setting fractured limbs while continuously monitoring the setting process by means of X ray exposure comprising an elongated portion having a hook at one end of sufficiently large arcuate extent to engage the limb externally and a handle at the other, the tool means being sufficiently long for grasping the handle out of the range of the X ray exposure area; a second tool means having a shape similar to that of said tool means for applying an opposing force to that applied by said tool means during the setting process to align the bone fragments.
Claim 5
Dependent Claim
100 words
A tool means for setting fractured limbs while continuously monitoring the setting process by means of X ray exposure comprising an elongated portion having a hook at one end of sufficiently large arcuate extent to engage the limb externally and a handle at the other, the tool means being sufficiently long for grasping the handle out of the range of the X ray exposure area; a second tool means having a shape similar to that of said tool means for applying an opposing force to that applied by said tool means during the setting process to align the bone fragments.
Claim 6
Dependent Claim
57 words
The tool set forth in claim 3 wherein each said tool means is made of at least two parts including an array of tool parts comprising hook-parts of different radii and different lengths, T-shaped handles of different lengths and extension members of different lengths, said hook, extension, and handle parts having disengageable means for fixedly engaging same.
Claim 7
Dependent Claim
19 words
The tool means set forth in claim 4 wherein said means for disengaging the parts comprises interengaging threaded portions.
Claim 8
Dependent Claim
25 words
The tool set forth in either of claims 4 or 5 wherein the hook parts have a transverse cross section of about half an inch.
