Abstract
Abstract An artificial plastic joint socket comprising a plastic joint socket body having a segmented spherical-shaped outer surface equipped with recesses for growth therein of the bone. Two essentially parallel plugs protrude from the outer surface of the joint socket body and are elastically connected therewith in such a manner that such plugs can adjust themselves with regard to the segmented spherical-shaped joint socket body owing to the bending forces occurring during implantation into the bone.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
95 words
An artificial joint socket formed of plastic for implantation in a bone comprising a plastic substantially semispherical shaped joint socket body having a segmented spherical shaped outer surface provided with depressions for the growth therein of the bone, a pair of plugs which are substantially in parallelism with one another protruding from the outer surface of the substantially semi-spherical shaped joint socket body and elastically connected therewith in such a manner that such can adjust themselves with respect to the joint socket body owing to the bending forces which arise during implanting in the bone.
Claim 2
Dependent Claim
95 words
An artificial joint socket formed of plastic for implantation in a bone comprising a plastic substantially semispherical shaped joint socket body having a segmented spherical shaped outer surface provided with depressions for the growth therein of the bone, a pair of plugs which are substantially in parallelism with one another protruding from the outer surface of the substantially semi-spherical shaped joint socket body and elastically connected therewith in such a manner that such can adjust themselves with respect to the joint socket body owing to the bending forces which arise during implanting in the bone.
Claim 3
Dependent Claim
15 words
The joint socket as defined in claim 1, further including means for reinforcing the plugs.
Claim 4
Dependent Claim
25 words
The joint socket as defined in claim 1, wherein the depressions for the growth therein of the bone are in the form of ring-shaped grooves.
Claim 5
Dependent Claim
28 words
The joint socket as defined in claim 1, wherein the joint socket body has an edge portion provided with at least one bore for receiving an attachment screw.
