Abstract
Abstract A multi-purpose internal fixation plate for stabilization of fractured or broken bones. The fixation plate comprises a central hub portion with a plurality of radial, integral fingers extending therefrom and evenly spaced thereabout. The fixation plate is designed to be cut to size and to the desired configuration by the total or partial removal of one or more selected ones of the fingers. The fixation plate is further designed to be bent to the desired shape depending upon the application for which it is used. The hub portion and the fingers may be provided with appropriately configured apertures through which they can be screwed by surgical screws to the bone or bones to be stabilized. The fixation plate is made of any appropriate surgically compatible, bendable and cutable material, having sufficient strength.

Claims Analysis
Total Claims: 24
Claim 1
Independent Claim
114 words
A multi-purpose internal universal fixation plate for the stabilization of fractured, broken and severed bones, said universal fixation plate comprising: a central hub portion; and a plurality of pairs of diametrically disposed fingers extending substantially radially from said hub portion, wherein said universal fixation plate is made from a material capable of being cut and bent and is characterized adequate strength and biocompatability for use as an endo-implant; and whereby said universal fixation plate is capable of being cut into any one of a number of differently configured fixation plates by selectively removing all,portions of, one or more of said fingers, thus eliminating the necessity of maintaining a inventory of differently configured fixation plates.
Claim 2
Dependent Claim
114 words
A multi-purpose internal universal fixation plate for the stabilization of fractured, broken and severed bones, said universal fixation plate comprising: a central hub portion; and a plurality of pairs of diametrically disposed fingers extending substantially radially from said hub portion, wherein said universal fixation plate is made from a material capable of being cut and bent and is characterized adequate strength and biocompatability for use as an endo-implant; and whereby said universal fixation plate is capable of being cut into any one of a number of differently configured fixation plates by selectively removing all,portions of, one or more of said fingers, thus eliminating the necessity of maintaining a inventory of differently configured fixation plates.
