title: Claudication of the cauda equina.
abstract: The term "claudication of the cauda equina" is examined. It has arisen from semantic errors, and a belief in ischaemia for which there is no scientific evidence. Its use tends to hamper rather than assist the investigation of patients with obscure pain in the lower limb. A preferable alternative term, "atypical sciatica", is suggested.
