Lloyd-Davies position is a medical term referring to a common position for surgical procedures involving the pelvis and lower abdomen.
The majority of colorectal and pelvic surgery is conducted with the patient in the Lloyd-Davies position.
It was popularised for these procedures by Oswald Lloyd-Davies working at St Marks Hospital London.
[1] It is derived from the Trendelenburg position but with the legs abducted to allow access to the perineum.
The basic angle is a 30-degree Trendelenburg with the hips flexed at 15 degrees; this can be adjusted with leg supports.
