The phenomenon of focal peripheral nerve constriction: review of the literature

Abstract

Today the description of phenomenon of the focal “hourglass-like constriction” of the peripheral nerves in patients with acute pain mononeuropathy is often found in literature. The use of additional imaging techniques of peripheral nerves such as high-resolution ultrasound and magnetic resonance imaging allowed to detect this pathology more often. The purpose of the review is to summarize information about the phenomenon of the focal “hourglass-like constriction”. We analyzed 30 publications in PubMed database by key words: “Hourglass like construction of peripheral nerve” with the description of 158 patients with the focal “hourglass-like constriction”.
