The tibial nerve exited from below both piriformis muscles and the common fibular nerve exited between the two muscle bellies. This presentation of accessory piriformis is unique and has seldom been presented in the literature. Anatomical accessory muscles such as this one has important clinical considerations including in surgery, radiology, and the diagnosis of sciatic pain caused by piriformis syndrome... Read More»
