Key points

  • The sciatic nerve arises from the sacral plexus and receives fibres from spinal nerves L4 to S3.
  • It usually leaves the pelvis below piriformis and travels deep within the buttock and back of the thigh.
  • Its tibial and common fibular components usually separate near the upper corner of the space behind the knee, although the level varies.
  • It supplies muscles at the back of the thigh directly and most muscles and skin below the knee through its branches.
