Sciatic neuropathy is an important consideration in the patient with foot drop. Causes of this mononeuropathy include total hip arthroplasty, unusual forms of leg or buttock compression, neoplasms, and a heterogeneous group of other disorders. In this update, the authors summarize the clinical, etiologic, diagnostic, and management issues regarding sciatic neuropathy.

Key points
