The ageing society leads to an increased risk of femoral neck fractures. Besides endoprotheses and established head‐conserving implants, the rotation‐stable screw anchor is used for surgical treatment. In this in vitro study, the influence of cemented versus non‐cemented implants is tested. Therefore, a novel test set‐up is used that is capable of simulating the load during gait cycles. Thereby, the transferability to clinical practise shall be increased. Additionally, time‐series data is recorded to evaluate clinically relevant parameters during the applied cyclical load. The results show that the test set‐up enables deeper insight to the implants behaviour during loading, which is of relevance due to the differences that can be observed between the cemented and non‐cemented implant. Additionally, the results are compared to the literature. (© 2017 Wiley‐VCH Verlag GmbH & Co. KGaA, Weinheim)
