<prompt> Investigation of choice for entrapment neuropathy is ?CT SCANClinical examinationUlrasonographyEMG NCV  <response>: Ans. is d i.e., EMG NCV The diagnosis of mononeuropathy in entrapment neuropathy is based on electrodiagnostic studies EMG NCV and Magnetic resonance imaging MRI. Entrapment neuropathy is a medical condition caused by entrapment and compression of a peripheral nerve wherever it traverses fibro-osseous tunnels. Sites of entrapment neuropathy are : - Carpal tunnel :- Median nerve carpal tunnel syndrome Cubital tunnel :- Ulnar nerve cubital tunnel syndrome Guyans canal :- Ulnar nerve Guyans canal syndrome Tarsal tunnel :- Posterior tibial nerve Tarsal tunnel syndrome Inguinal ligament :- Lateral cutaneous nerve of thigh meralgia paraesthetica. Suprascapular notch :- Suprascapular nerve Neck of fibula :- Common peroneal nerve Fascial tunnel of superficial peroneal nerve :- Superficial peroneal nerve Arcase of Frohse :- Posterior interosseous syndrome Thoracic outlet :- Lower trunk of brachial plexus Compression in the foot :- Digital nerve Moens metatarsalgia
