| Piriformis | |
|---|---|
| Muscle Type | |
| Origin | 2, 3, 4 costotransverse bars of anterior sacrum, few fibers from superior border of greater sciatic notch |
| Insertion | Anterior part of medial aspect of greater trochanter of femur |
| Action | Externally rotates and stabilises the hip |
| Synergists | The [[Lateral Hip RotatorsProperty "Has muscle synergists" (as page type) with input value "The [[Lateral Hip Rotators" contains invalid characters or is incomplete and therefore can cause unexpected results during a query or annotation process. |
| Antagonists | |
| Spinal innervation | S1, S2 |
| Peripheral Innervation | Nerve to piriformis |
| Vasculature | Inferior gluteal, lateral sacral and superior gluteal artery. |
| Feature | Piriformis Syndrome |
