Abstract
Abstract An artificial humerus head has a groove in its exterior surface for receiving the long biceps tendon. A cover bridges the groove to form an elongated open-end channel for the tendon and makes it possible to arrange the long biceps tendon in the channel without separation thereof from the head.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
An artificial humerus head comprising an elongated unitary member having a pin at one end thereof for insertion into the shaft of a humerus, a substantially spherical head at the other end thereof, and a shaft between said pin and head adapted to act as a continuation of the humerus when said pin is inserted into the shaft of the humerus, said spherical head having an elongated groove formed in its exterior surface for longitudinally receiving the long biceps tendon, said groove extending generally in the direction of elongation of said member between spaced points on the outer periphery of said head and being oriented at a slight angle to the longitudinal axis of said elongated member, and a cover member covering said groove and cooperating with said groove to form an open-ended, enclosed channel for the long biceps tendon extending through said head generally in the direction of elongation of said member.
Claim 2
Dependent Claim
153 words
An artificial humerus head comprising an elongated unitary member having a pin at one end thereof for insertion into the shaft of a humerus, a substantially spherical head at the other end thereof, and a shaft between said pin and head adapted to act as a continuation of the humerus when said pin is inserted into the shaft of the humerus, said spherical head having an elongated groove formed in its exterior surface for longitudinally receiving the long biceps tendon, said groove extending generally in the direction of elongation of said member between spaced points on the outer periphery of said head and being oriented at a slight angle to the longitudinal axis of said elongated member, and a cover member covering said groove and cooperating with said groove to form an open-ended, enclosed channel for the long biceps tendon extending through said head generally in the direction of elongation of said member.
Claim 3
Dependent Claim
25 words
The artificial humerus head of claim 1 wherein a portion of said groove extends into the exterior surface of the shaft of said elongated member.
Claim 4
Dependent Claim
36 words
The artificial humerus head of claim 1 or 2 wherein said cover member is an element separate from said head, and means for securing said cover member to said head in overlying relation to said groove.
Claim 5
Dependent Claim
49 words
The artificial humerus head of claim 1 or 2 wherein said cover member is an elongated element separate from said head, said cover member being slidably insertible into said groove with the opposing exterior sides of said elongated cover member engaging the interior opposing sides of said elongated groove.
Claim 6
Dependent Claim
24 words
The artificial humerus head of claim 4 including a locking pin for securing said slidable cover member in fixed position relative to said groove.
Claim 7
Dependent Claim
26 words
The artificial humerus head of claim 4 wherein said exterior sides of said cover member and said interior sides of said groove exhibit complementary dovetail configurations.
Claim 8
Dependent Claim
30 words
The artificial humerus head of claim 1 or 2 wherein the outer surface of said cover means is contoured as a smooth continuation of the outer contour of said head.
