Lowest Point
Eycleshymer and Schoemaker reported the lowest point of the cecum to range from the fourth lumbar disk to the lower portion of the fifth sacral vertebra. The average position is at the level of the second sacral disk. Treves and Sobotta found the position of the apex of the cecum on the medial side of the middle of the inguinal (Poupart's) ligament.
Ileocecal Valve
Eycleshymer and Schoemaker found the valve to lie from the level of the third lumbar disk to the upper third of the second sacral vertebra. The average position was found to be at the level of the middle of the fifth lumbar vertebra. Cunningham and Morris both place it at the point of intersection of the intertubercular and inguinal (Poupart's) lines.
