ABSTRACT
Positioning for lateral femur projection. https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315382210/8ca82e7c-bd07-4171-b4f5-ebaded57b5b3/content/fig2_27a.jpg" xmlns:xlink="https://www.w3.org/1999/xlink"/>
From the antero-posterior position, the patient rotates onto the affected side. The knee is slightly flexed and the patient adjusted so that the thigh is positioned on the centre line of the table.
The pelvis is rotated backwards to separate the thighs.
The position of the limb is then adjusted to vertically superimpose the femoral condyles.
The image receptor/Bucky mechanism is located directly under the lateral aspect of the thigh to include the knee joint and as much of the femur as possible.
Pads are used to support the opposite limb in a position behind the one being examined.
Alternatively, a CR cassette or mobile DDR detector is positioned directly under the thigh to include the knee and hip joints.
