Piriformis Syndrome
Nutation of the sacrum, places the Piriformis Muscle (PM) on a Stretch. This can entrap the Sciatic Nerve (black arrow) between the muscle belly of the Piriformis and the Greater Sciatic Notch resulting in symptoms that micmic Sciatica
Yeoman was the first describe piriformis syndrome in 1928. Based on 100 case studies (patients with low back pain), Yeoman diagnosed 36 as having periarthritis involving the anterior sacroiliac ligament, the piriformis muscle and the adjacent radicals of the sciatic nerve (although Yeoman do not mention the term 'piriformis syndrome' in his original paper).
In one recent hospital study, 45 of 750 patients with low back pain were found to have piriformis syndrome. Other studies have estimated the incidence of piriformis syndrome in sciatic patients at 6%.
Symptomatic Profile
- Chronic pain in the buttocks (may radiate to the lower leg, increases with walking or squatting, may imitate low pack pain)
- Pain with bowel movements
- Pain the labia majora in women, pain in the scrotum in men
- Dyspareunia in women
- Pain when arising from bed
- Pain increased with hip adduction and internal rotation
- Intolerance to sitting
In approximately 15% of the population, the peroneal portion of the sciatic nerve passes through the muscle belly of the piriformis muscle, or the undivided sciatic nerve penetrates the belly of the piriformis muscle. These people are more prone to develop a mechanically induced piriformis syndrome (Chaitow and Walker, 2000
