Abstract
Eight patients with an anomaly of the iliac bone consisting of a protuberance projecting into the greater sciatic notch are discussed. The anomaly may be associated with sciatic nerve compression and atrophy; sacral, buttock, or intradural lipomata; tethered spinal cord; and ipsilateral lower extremity weakness. Surgical treatment can result in improvement of neurologic symptoms and signs.
