The condition is caused by the irritation or compression of the proximal sciatic nerve by the piriformis muscle, which connects the sciatic notch with the greater trochanter of the femur
the sarcum, the coccyx and the piriformis muscle
Both the femur and tibia are long bones that form a joint. The menisci or articular discs are structures that separate a joint cavity in to two compartments.
