El nervio ciático sale de la pelvis y entra en la región glútea debajo del músculo piriforme como un único tronco. Tiene dos componentes: el nervio peroneo común y el nervio tibial. La relación variable del nervio ciático con el músculo piriforme y su longitud hace que el nervio sea vulnerable a las lesiones. Estudiamos la relación variable del nervio ciático en sesenta extremidades inferiores de treinta cadáveres y encontramos el nervio ciático emergiendo indiviso por debajo del músculo piriforme en el 68,33% de los casos, pero en el 31,66% el nervio ciático estaba dividido arriba en la pelvis. En el 18,33% de los casos el componente peroneo común emergió arriba y en el 13,33% de los casos emergió a través del músculo piriforme. Pensamos que tener un conocimiento adecuado sobre la anatomía del nervio ciático es bueno para los resultados clínicos.
Sciatic nerve leaves the pelvis and enters the gluteal region below the piriformis muscle as single trunk. It has two components common peroneal nerve and the tibial nerve. The variable relationship of sciatic nerve with the piriformis muscle and its long course makes the nerve vulnerable to injury. We studied sciatic nerve variable relation in sixty lower extremities of thirty cadavers and found the sciatic nerve emerging undivided below the piriformis muscle in 68.33% of cases but in 31.66% the sciatic nerve divided high in the pelvis. In 18.33% cases the common peroneal component emerged above and in 13.33% of cases it emerged through the piriformis muscle. We think proper knowledge of the anatomy of the sciatic nerve is good for clinical outcomes
