Place the patient supine on a radiolucent table. A small bolster can be placed beneath the buttock to prevent external rotation of the lower extremity.
Supine position knee flexed 30°
Position the patient supine on a radiolucent table with the knee in 30° flexion. The knee is supported by a cushion, or rolled sheets.
Supine position on a split table
Position the patient supine on a radiolucent table, slightly head down 10° to prevent sliding towards the foot of the table.
Supine - unilateral leg support
Place the patient supine on a radiolucent operating table and flex the knee of the injured leg, with the lower leg and foot hanging free.
Supine position knee flexed 90°
Commercially available carbon triangles can be used to support the leg during retrograde nailing of the femur. This allows easy access to the intercondylar notch.
Supine position for arthroscopy
Place the patient supine on the operation table. Use a thigh support to bring the knee into flexion of at least 30°.
Position the patient prone on a radiolucent table. Place cushions under the chest, pelvis, distal thigh, ankle and eyes, to avoid pressure sores.
