The terminal position of the caudal sac is variable. We examined the position in 100 cases who had undergone myelography. The caudal sac closed proximally to the L5/S1 disc level in 3 cases, between L5/S1 and S1/S2 disc level in 41 cases, between S1/S2 and S2/S3 disc level in 55 cases, and caudally to S2/S3 disc level in one case.
