Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
96 words
A total shoulder prosthesis comprising in combination: a. a humeral component having a spherical end and means for fastening said humeral component to a decapitated humerus, b. a glenoid component including a socket adapted to replace a normal glenoid cavity and means for attaching said glenoid component between the spine of the acromion and the coracoid process wherein; c. the radius of curvature of said socket is greater than the radius of curvature of said spherical end whereby the fulcrum point of the prosthesis moves as the humeral component moves with respect to the glenoid component.
Claim 2
Dependent Claim
96 words
A total shoulder prosthesis comprising in combination: a. a humeral component having a spherical end and means for fastening said humeral component to a decapitated humerus, b. a glenoid component including a socket adapted to replace a normal glenoid cavity and means for attaching said glenoid component between the spine of the acromion and the coracoid process wherein; c. the radius of curvature of said socket is greater than the radius of curvature of said spherical end whereby the fulcrum point of the prosthesis moves as the humeral component moves with respect to the glenoid component.
Claim 3
Dependent Claim
49 words
The prosthesis of claim 1 wherein said humeral component has a shaft extending opposite said hemispherical end with a V-shaped notch on the front and back surfaces of the lower terminal edge of the hemispherical end and having a plurality of holes along the edges of the V-shaped notches.
Claim 4
Dependent Claim
24 words
The prosthesis of claim 1 wherein the ratio of the radius of curvature of the socket to the ball is from 1.5 to 3.
Claim 5
Dependent Claim
59 words
A humeral component for a shoulder prosthesis comprising in combination: a. a first end having a spheroidal shape, b. a second end including a shaft for attaching said component to a decapitated humerus, c. said first end terminating in a lower edge having V-shaped notches at the front and back thereof, and a plurality of holes surrounding said notches.
Claim 6
Dependent Claim
59 words
A humeral component for a shoulder prosthesis comprising in combination: a. a first end having a spheroidal shape, b. a second end including a shaft for attaching said component to a decapitated humerus, c. said first end terminating in a lower edge having V-shaped notches at the front and back thereof, and a plurality of holes surrounding said notches.
