Deep needling will directly contact the sciatic nerve (causing a strong electrical sensation in the leg). Ensure the sensation is not excessively painful.
📍 Location (classical)
On the posterolateral aspect of the hip, at the junction of the lateral one-third and the medial two-thirds of the line connecting the most prominent point of the greater trochanter and the sacral hiatus.
🧭 How to find it (practical)
In lateral decubitus, locate the point in the posterior depression of the greater
trochanter, at the junction of the lateral one-third with the middle one-third of the distance between the greater
trochanter of the femur and the intergluteal cleft. (Fig. 11.21)
🔬 Anatomy
Gluteus maximus and piriformis muscles. The thickest part of the sciatic nerve passes directly deep to this point. Innervated by the inferior gluteal nerve.
