Terminal Latency Index, Residual Latency, and Median-Ulnar F-Wave Latency Difference in Carpal Tunnel Syndrome.

Ann Indian Acad Neurol 2019 Apr-Jun;22(2):175-179

Department of Physical Medicine and Rehabilitation, Private Derman Hospital, Kirklareli, Turkey.

Introduction: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy, but no electrodiagnostic test alone shows sufficient sensitivity for CTS. We aimed to investigate the value of median motor terminal latency index (mTLI), median motor residual latency (mRL), and median-ulnar F-wave latency difference (FdifMU) as additional tests to nerve conduction studies which are performed traditionally in electromyography laboratories.

Methods: This is a retrospective study. Read More

Tardy Ulnar Nerve Palsy.

J Am Acad Orthop Surg 2019 Mar 28. Epub 2019 Mar 28.

From the Orthopedic Department (Dr. Rubin, Dr. Orbach, Dr. Bor, and Prof. Rozen), Emek Medical Center, Afula, Israel, and the Faculty of Medicine (Dr. Rubin, Dr. Bor, and Prof. Rozen), Technion, Haifa, Israel.

Tardy ulnar nerve palsy is a chronic clinical condition characterized by a delayed onset ulnar neuropathy after an injury to the elbow. Typically, tardy ulnar nerve palsy occurs as a consequence of nonunion of pediatric lateral condyle fractures at the elbow, which eventually lead to a cubitus valgus deformity. While the child grows, the deformity worsens and the ulnar nerve is gradually stretched until classic symptoms of ulnar nerve neuropathy appear. Read More

Supercharge End-to-Side Anterior Interosseous Nerve to Ulnar Motor Nerve Transfer for Severe Ulnar Neuropathy: Two Cases Suggesting Recovery Secondary to Nerve Transfer.

J Orthop Case Rep 2018 Sep-Oct;8(5):25-28

Department of Orthopedic Surgery, University of British Columbia St. Paul's Hospital -3rd Floor, Room 339A 1081 Burrard Street, Vancouver, BC V6Z 1Y6, Canada.

Introduction: The supercharged end-to-side (SETS) anterior interosseous nerve (AIN) to ulnar nerve transfer has been recently described for severe cubital tunnel syndrome. Previous studies have suggested that this technique augments or "babysits" the motor end plates until reinnervation occurs; however, it has more recently been suggested that reinnervation occurs by the donor nerve as evidenced in animal research.

Case Report: We present two cases of rapidly progressive ulnar neuropathy who underwent a SETS AIN to ulnar nerve transfer who demonstrated improvement in their electrodiagnostic studies in addition to improvement in their clinical and patient-reported outcome's scores postoperatively. Read More
