Abstract
The help of collared Corail® stems in present calcar fractures as well as the influence on stability in a standing position were investigated. 24 femur Sawbones® were dived in 4 groups: Collared stems were compared with collarless as well as calcar split and intact femurs. Mechanical testing was performed on a Zwick/Roell Z010 material testing machine with preloading of 2400 Newton and followed by external rotational load. No loosening was found in intact femurs with collared stems, but loosening with collarless stems at 55.8 Newton. Significantly fewer loads (31.7 N, 24.8 N) were needed in fractured femurs. A collar did not improve the stability significantly. A collar improves the immediate stability, but not in a present calcar fracture of the femur.
