Abstract
Abstract An elongated plate element extends on the exterior of the femur shaft and the greater trochanter across the adjacent ends. One end of the plate includes a right angle anchor element embedded in the femur shaft and the opposite end includes a pair of outwardly diverging return bend hook elements anchored in the outer end of the trochanter. A bend is provided in the plate element which positions the opposite portions in spaced apart parallel planes. An elongated slot is provided in the plate element and a pin extends through the slot into the femur shaft.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
106 words
A trochanteric plate for fastening the greater trochanter to the shaft of the femur, said plate comprising, an elongated plate element adapted to be placed on the exterior of the femur shaft and trochanter and extend across their meeting ends, a hook element on one end of said plate element extending at a right angle thereto and adapted to be anchored in said femur shaft, and a pair of outwardly diverging return bend hook elements on the opposite end of said plate element extending in a plane parallel to the plane of said plate element and adapted to be anchored in the end of said trochanter.
Claim 2
Dependent Claim
106 words
A trochanteric plate for fastening the greater trochanter to the shaft of the femur, said plate comprising, an elongated plate element adapted to be placed on the exterior of the femur shaft and trochanter and extend across their meeting ends, a hook element on one end of said plate element extending at a right angle thereto and adapted to be anchored in said femur shaft, and a pair of outwardly diverging return bend hook elements on the opposite end of said plate element extending in a plane parallel to the plane of said plate element and adapted to be anchored in the end of said trochanter.
Claim 3
Dependent Claim
48 words
The structure of claim 1 wherein said plate element includes a bend intermediate its ends which positions portions on opposite sides of said bend in parallel spaced apart plaNes whereby said plate portions and bend are adapted to matingly engage the exterior of said femur shaft and trochanter.
Claim 4
Dependent Claim
24 words
The structure of claim 1 wherein an anchor pin extends from said plate element and is adapted to be anchored in said femur shaft.
Claim 5
Independent Claim
152 words
The method of fastening the greater trochanter to the shaft of the femur by a trochanteric plate being elongated and having a hook element on one end and a pair of outwardly diverging hook elements on the opposite end of said plate extending perpendicularly to said first hook element, said pair of hook elements including return bends which position the outer end portions of said hook elements in a plane parallel with said plate element, and said plate element includes an elongated slot extending longitudinally of said plate element; including the steps of driving the outer ends of said pair of hook elements into the outer end of the greater trochanter and positioning the elongated plate over and across the trochanter cut with the hook on said one end being driven into shaft of the femur and a screw fastening means being driven through said slot into the shaft of said femur.
Claim 6
Independent Claim
152 words
The method of fastening the greater trochanter to the shaft of the femur by a trochanteric plate being elongated and having a hook element on one end and a pair of outwardly diverging hook elements on the opposite end of said plate extending perpendicularly to said first hook element, said pair of hook elements including return bends which position the outer end portions of said hook elements in a plane parallel with said plate element, and said plate element includes an elongated slot extending longitudinally of said plate element; including the steps of driving the outer ends of said pair of hook elements into the outer end of the greater trochanter and positioning the elongated plate over and across the trochanter cut with the hook on said one end being driven into shaft of the femur and a screw fastening means being driven through said slot into the shaft of said femur.
Claim 7
Dependent Claim
27 words
The structure of claim 1 wherein the outer ends of said pair of hook elements extend in a plane parallel to the plane of said plate element.
