title: Trochanteric sciatic neuropathy.
abstract: A patient with severe weakness, atrophy, and sensory loss of the right leg had a focal right sciatic neuropathy. The sciatic nerve was enlarged at the level of the lesser trochanter, excessively firm, and multistranded; its stimulation threshold was focally increased. Biopsied fascicles had reduplicated perineurial leaflets, many Renaut bodies, and an abnormal unimodal spectrum of small-diameter fibers. We postulate that the lesion was induced by the combination of an underlying prominent lesser trochanter and sitting on hard benches.
