Screw-in-Cup

Threaded conical cup in standard and osteoporosis versions. The conical shape, together with its concave base provide a great stability, including cases of displasia or lateral defect.

The cutting thread with teeth of decreasing depth facilitate the insertion and the centering. The various available modular inserts allow for alumina-alumina or metal-metal coupling.

A version for the osteoporotic acetabulum is also available, using the same instrumentation and the same broad range of inserts.
