The Bencox I Template System, is designed for the preoperative evaluation of the implant size, offset, and leg length, with the goal of restoring patient's normal anatomy and hip biomechanics. For the preoperative assessment of the component size, templates are generally used on an A/P X-ray of the pelvis, including both hips and a lateral view of the affected hip. X-ray overlays are available in 115% magnification for Bencox n femoral components, and an A/P X-ray/scanogram with 115% magnification in an internal rotation of 10-15°, as needed.(X-ray overlays are available in 100%, 110%, 115%, 120% magnification)Next, mark the center of rotation of the femoral head on the normal side of preoperative x-ray. Overlay the template onto the A/P X-ray to ensure that the midline of the Implant Is aligned over the anatomical axis of the femoral medullary canal. As the Bencox I stem is a rectangular-shaped stem, unlike a round-corner stem, it should not be measured tightly on the A/P radiograph for stem selection verification.
To reconstruct the normal hip, the head-lesser distance (measure from the head center to the level above the lesser trochanter) can be used as the neck length pre-operatlvely and intra-operatlvely.
