SUPINE - Frog Leg (Modified Dorsal Recumbent)


Patient is first positioned in a dorsal recumbent position (supine position with knees flexed upward and the thighs are slightly externally rotated - outward).  The soles of the feet rest on the operating bed and pillows are placed under the knees for support.

The "Frog Leg" position is accomplished by exaggerating the external rotation of the knees, drawing the soles of the feet upward to the body until soles are resting against each other.  Again, knees should be supported with pillows to help prevent hyperextension.  Padding is placed under the lateral sides of feet and ankles (resting on the bed).


  • increase surgical exposure to both the vagina, perineum and abdomen.


  1. The patient is placed in the Basic - Supine Position

  2. The patient is secured to the table with tape or belt across the hips (if not part of surgical field) between the iliac crest and the head of the femur to prevent  aseptic necrosis of the femur head. 

  3. The knees are bent and the soles of the feet touch. 

  4. Wedges, pillows, or blankets are placed beneath the knees to support the legs and prevent long thoracic nerve injury. 

  5. Padding is also placed under the lateral ankles and feet.

  6. Feet can be lightly secured if necessary, after padding across the top, with a Velcro belt or tape to prevent feet from sliding or legs from falling off the bed.
