Biomechanical evaluation of the expansive cannulated screw for fixation of femoral neck fractures.

Femoral neck fracture is one of the common clinical traumas, especially amongst elder patients. This study aims to test, compare and evaluate the bone-screw interface strengths, the fatigue strengths, and the stabilities of our newly designed expansive cannulated screw (ECS) and the common cannulated compression screw (CCS) in the fixation of femoral neck fracture, which is a summary of recent research. Zhang Y, Tian L, Yan Y, Sang H, Ma Z, Jie Q, Lei W, Wu Z.
