Department of Orthopaedics, University of Pittsburgh, Pittsburgh, PA.

Purpose: The purpose of the study was to determine the rate of false positives for nerve conduction studies (NCSs) and ultrasound (US) in a population without signs and symptoms of carpal tunnel syndrome (CTS) using a CTS-6 score of 0 as the reference standard.

Methods: Patients were included in this study if they were referred for NCSs for a reason other than CTS (cubital tunnel syndrome and/or cervical radiculopathy) and they had a CTS-6 score of 0. An US measurement of the cross-sectional area (CSA) of the median nerve at the level of the carpal tunnel inlet was performed by a certified ultrasound technician. Read More

For severe cubital tunnel syndrome, patients with absent sensory nerve action potential tend to have more severe nerve damage than those without. Thus, it is speculated that such patients generally have a poor prognosis. How absent sensory nerve action potential affects surgical outcomes remains uncertain owing to a scarcity of reports and conflicting results. Read More

Cubital tunnel syndrome is the second most common peripheral nerve compression seen by hand surgeons. A thorough understanding of the ulnar nerve anatomy and common sites of compression are required to determine the cause of the neuropathy and proper treatment. Recognizing the various clinical presentations of ulnar nerve compression can guide the surgeon to choose examination tests that aid in localizing the site of compression. Read More

Neurosurgery, Seattle Science Foundation, Seattle, USA.

Introduction A reoperation for a cubital tunnel syndrome is not uncommon. Patients often complain of sensorimotor symptoms in the ulnar nerve distribution after their primary surgery. The documented etiologies for such a phenomenon include a "new" kinking of the distal ulnar nerve and a "new" compression of the ulnar nerve by the fascial septum in between or tendinous bands over the muscles of the forearm.

Background: In cubital tunnel syndrome (CuTS), chronic compression often occurs at the origin of the flexor carpi ulnaris at the medial epicondyle. Motor nerve conduction velocity (NCV) across the elbow is assessed preoperatively to corroborate the clinical impression of CuTS. The purpose of this study was to correlate preoperative NCV to the direct measurements of ulnar nerve size about the elbow at the time of surgery in patients with clinical and/or electrodiagnostic evidence of CuTS.

J Hand Surg Asian Pac Vol 2018 Mar;23(1):90-95

* Okutsu Minimally Invasive Orthopaedic Clinic, Tokyo, Japan.

Background: Some long-term hemodialysis patients suffer from multi-recurrent carpal tunnel syndrome because amyloid originating from β-microglobulin continues to be deposited mainly in the flexor tendons, tendon sheaths and flexor retinaculum during maintenance hemodialysis. These amyloid deposits inside carpal canal (tunnel) tissues increase carpal canal pressure and this leads to compression of the median nerve. When multi-recurrent carpal tunnel syndrome occurs, previous operative scarring of soft tissue may prohibit further enlargement of the carpal canal even if any carpal canal decompression procedure is used.

Cubital tunnel syndrome refers to ulnar nerve compressive neuropathy and most commonly occurs at the level of the elbow. Surgical options include in situ decompression, decompression with anterior transposition of the ulnar nerve, and medial epicondylectomy with or without decompression. With the advancement of endoscopic surgery, techniques of endoscopic in situ decompression of the ulnar nerve, endoscopy-assisted anterior transposition, and endoscopic anterior transposition of the ulnar nerve have been reported with the advantage of minimally invasive surgery.
