The distal sciatic bifurcates generally above the popliteal fossa. Most clinicians start in the popliteal fossa, identify the tibial nerve and then slowly slide cephalad to watch the common peroneal nerve join to form the distal sciatic nerve.
Great block for bimall or trimal fractures that need reduction/pain control. You miss the saphenous (off the femoral), but often not needed.
Flat needle angle entry when the patient is prone.

Post-block scan : note anesthetic around both tibial and fibular (common peroneal nerve)
