The bending stability of cemented femoral neck osteotomies. An experimental study.

Stabilization by bone cement in combination with a nail improves significantly the bending stability of experimental femoral neck osteotomies compared with fixation by a simple Thornton's nail. The stability achieved by a cemented nail in cases of femoral neck fractures, seems to be sufficient for the dynamic forces acting upon the femoral head during carefully walking with full weight-bearing. However, there are still many unanswered questions concerning clinical use of bone cement in femoral neck fractures.
