This pitfall can be avoided by obtaining both AP and cross-table lateral x-rays when evaluating proximal femur fractures. If these x-rays do not clarify the nature of the fracture pattern, an x-ray taken with the extremity internally rotated should be taken. We recommend for the surgeon not to use a dynamic screw for the reverse obliquity type pattern, nor to place the lag screw away from the center-center position and farther than 1 cm from the subchondral bone. We recommend for the surgeon to avoid bending the guide pin during reaming, also avoiding bending the guide pin within the reamer resulting in intra-articular or intra-pelvic penetration.
