A comparison of femoral neck fixation with the reconstruction nail versus cancellous screws in anatomic specimens


, : A comparison of femoral neck fixation with the reconstruction nail versus cancellous screws in anatomic specimens. Clinical Orthopaedics and Related Research: 189-196

Femoral neck fixation techniques were applied to five matched pairs of autopsy specimens to evaluate the fixation of the Russell-Taylor femoral nail in ipsilateral neck and shaft fractures of the femur. Reconstruction nail fixation of the femoral neck was compared with that of three parallel screws. The intact and postfixation femora were subjected to an applied bending moment in 0 degrees, 30 degrees, and 90 degrees of simulated hip flexion. The bending stiffness was determined from the load deformation data for each intact femur and then after the appropriate fixation. The fatigue response of the fixation, presence of osteopenia, degree of fracture reduction, and device alignment showed that the stiffness ratio (fixed to normal) of the nail was greater in most specimens. There was no statistical difference in retained stiffness after cyclic loading between the nail and cancellous screw fixations. The ultimate strength of the nail was 2.5 times the strength of the screw fixation of the femoral neck. Thus, the nail provided biomechanically sound fixation of the femoral neck.
