Abstract:
We examined the anatomical height and shape of the conus medullaris in 602 cases using magnetic resonance imaging. The peak of the distribution of the conus height was at the middle one-third of L1. The comparison of the conus level had no significant relationships with age or sex, but the juvenile group had more a caudal distribution of the conus level. The shape of the conus medullaris was classified into three types, and the type B was most frequently observed.
