Femoral Head Lag Screw Position for Cephalomedullary Nails: A Biomechanical Analysis
Journal of Orthopaedic Trauma, 06/29/2012
Kuzyk PRT et al. – The inferior lag screw position produced the highest axial and torsional stiffness. Anterior and posterior lag screw positions produced the lowest stiffnesses and load–to–failure. Inferior placement of the lag screw on the anteroposterior radiograph and central placement on the lateral radiographs is recommended.
