Abstract
Abstract Surgical pins for connecting osseous tissue wherein the pins are readily separable and identifiable under Xray conditions by reason of the inclusion on the shank of the pin in addition to all of the operating elements of the pin of additional three dimensional markings such as screw threads with different such markings for each of the pins which may be used at a particular location so that the pins may be readily identified and segregated.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
120 words
A method of detecting any incorrectly placed orthopedic pin in a set of orthopedic pins inserted in osseous tissue, which comprises providing a set of orthopedic pins wherein each said pin has a threaded end, a shank, and a head for receiving a turning tool and wherein the shanks of said pins are provided with a pin identification member spaced from the threaded end of the respective pin, said members being visibly different so as to be individually identifiable in an X-ray radiograph; inserting said pins in osseous tissue; providing an X-ray radiograph of said tissue with the pins inserted; and examining said radiograph to compare pin locations by means of said differing members to detect an incorrectly located pin.
Claim 2
Independent Claim
120 words
A method of detecting any incorrectly placed orthopedic pin in a set of orthopedic pins inserted in osseous tissue, which comprises providing a set of orthopedic pins wherein each said pin has a threaded end, a shank, and a head for receiving a turning tool and wherein the shanks of said pins are provided with a pin identification member spaced from the threaded end of the respective pin, said members being visibly different so as to be individually identifiable in an X-ray radiograph; inserting said pins in osseous tissue; providing an X-ray radiograph of said tissue with the pins inserted; and examining said radiograph to compare pin locations by means of said differing members to detect an incorrectly located pin.
Claim 3
Dependent Claim
26 words
A method as set forth in claim 1, wherein said identification members are integral with the material of said pin shanks and encompass the respective shanks.
Claim 4
Dependent Claim
46 words
A method as set forth in claim 1, wherein said identification members are comprised of an increasing number of screw threads from pin to pin and said threads being capable of screwing into osseous tissue and matching the pitch of the threaded ends of respective pins.
Claim 5
Dependent Claim
37 words
A method as set forth in claim 1, including in said set a pin having a shank without an identification member so as to be thus distinguishable by X-ray radiograph from the other pins of said set.
