The spherical BSC Hip Cup developed in collaboration with Prof. Dr. med. G. Biehl, has the purpose to achieve the optimal restoration of the anatomical cup function of the hip joint under physiological load. The press-fit cup is slightly flattened at the pole and is larger in diameter than the prereamed acetabular bed in the bone. 11 diameter sizes from 46 to 66 mm allow an optimal adaptation to the anatomical conditions. A good secondary stability is achieved through a rough surface coating of pure titanium with a roughness value of Ra 30-35 μm so that a good osseointegration is ensured. In addition, bone screws may be used.
Both polyethylene and ceramic liners are available. 4 liner sizes cover all 11 cup sizes. The polyethylene liners are also available in a 10° dysplasia version with an anti-dislocation shoulder.
It‘s possible to use ballheads with 36mm diameter from cup size 50 with ceramic liners. From cup size 54 it‘s possible to use 40 ballheads in ceramic.
