Long-term results and clinical success of a cementless hip stem decisive depend on the primary stability at the time of operation and is the most important factor for osseo-integration (1,6,13,15) Noble et al. (14) have emphasized the difficulties of achieving press-fit and demonstrated the influence of stem design and anatomical variations of the proximal femur. Gaps between implant and bone may particularly occur when contemporary broaching techniques are used which are susceptible to surgical error (18). As a consequence, more sophisticated methods of bone cavity preparation have emerged. Experimental work has led to the development and clinical introduction of robotic systems for orthopaedic surgical application (17).
