BACKGROUND: The design and the surgical technique of the Silent Micro Hip™ are different compared to other hip stems due to a conical shape for fixation within the metaphyseal femur. The purpose of the present study was to evaluate hip joint biomechanics of the Silent Micro Hip™ in comparison to other implants. Implant-specific differences are highlighted. MATERIAL AND METHOD: 150 consecutive patients (each group 50 Silent Micro Hip™, Nanos™ and SL-Plus™ MIA) were analysed retrospectively. For evaluation of biomechanical parameters pre- and postoperative X-rays (pelvic AP views) were used. RESULTS: The horizontal femoral offset and the limb length showed no significant difference between the Silent Micro Hip™ and the Nanos™ or SL-Plus™ MIA stem at the reconstructed hip. An almost anatomic reconstruction of hip joint biomechanics was reached with all three types of implants. CONCLUSIONS: The Silent Micro Hip™ allows for almost anatomic reconstruction of hip joint biomechanics. Short-term results support the bone-preserving reconstruction with a proximal femoral load transfer. Further studies on the mid- and long-term outcomes are ongoing.
