Abstract
The invention relates to an artificial joint shell having an outer shell (2) which is implantable in a bone base and a retro-fittable inner shell (3), the inner and outer shells being fixable to one another via a friction-locked clamping force (5), preferably via a self-locking, conical connection. A tunnel (6) is formed in the partition surface (4) between the two shells (2, 3) and connects two points at the shell edge in an arc (37) that extends towards the shell base (7). A wire (8) is threaded through the tunnel (6), and by applying an extraction force to the wire the inner shell (3) is extracted. The extraction force is uniformly applied to the inner insert along the arc (37) prescribed by the tunnel and does not damage the inner shell.
