System for osteosynthesis at the vertebral column, connecting element

The hemispherical acetabulum has a pin which projects from the cup of the acetabulum on an angle of 45.degree. relative to the polar axis. A sleeve which closes over the pin is rotatably mounted on the pin to facilitate twisting of the cup into a correct position when implanted in a pelvis. The sleeve is made of metal to preclude direct contact between the pin which may be made of plastic and the pelvis bone tissue.

Hemispherical acetabulum

The shank is provided with a recess in the proximal medial region and a U-shaped wire mesh structure is secured within the recess. The wire mesh structure provides for an ingrowth of bone tissue at the medial narrow side of the shank and an absorption of shear micro movements between a bone and the implant. The mesh structure can be secured in place by rivets or by weld seams.
