Long-term results and survivorship of Protasul 10 straight stem Müller femoral hip prosthesis.

In a retrospective study 88 consecutively cemented Protasul 10 straight stem total hip prostheses, implanted during a two year period, were investigated. After a nine to ten year period 8 hips had been revised. In the clinically and radiologically checked group, the patients' opinion was in 82% very good or good, in 9% moderate and in 9% bad. The X-Ray findings showed in 20% an initial or advanced loosening of the stem and/or the cup. The survivorship after a nine to ten year period is 89%.
