Compression of the Ulnar Nerve by the Arcade of Struthers: Look and You Shall Find.

Background: The arcade of Struthers was first proposed by Kane et al in 1973. Clinical investigations of this structure have been limited to small case series, focusing on the arcade as an isolated cause of compressive ulnar neuropathy. The purpose of our study was to investigate the incidence of this structure in patients undergoing ulnar nerve transposition.

Incidence of Nerve Injury After Extremity Trauma in the United States.

Background: Traumatic peripheral nerve injuries cause chronic pain, disability, and long-term reductions in quality of life. However, their incidence after extremity trauma remains poorly understood.

Methods: The IBM® MarketScan® Commercial Database from 2010 to 2015 was used to identify patients aged 18 to 64 who presented to emergency departments for upper and/or lower extremity traumas.

Refining Indications for the Supercharge End-to-Side Anterior Interosseous to Ulnar Motor Nerve Transfer in Cubital Tunnel Syndrome.

The supercharge end-to-side anterior interosseous to ulnar motor nerve transfer has gained popularity over the past decade as a method of augmenting intrinsic muscle reinnervation in patients with acute neurotmetic ulnar nerve injuries. Controversy remains regarding its efficacy and appropriate clinical indications in cubital tunnel syndrome, where the timing of onset of axonal loss is less clear. The authors present guidelines for patient selection, surgical technique, and postoperative rehabilitation based on their clinical experience with the technique in this patient population.

Compound Muscle Action Potential Amplitude Predicts the Severity of Cubital Tunnel Syndrome.

Background: Cubital tunnel syndrome has a spectrum of presentations ranging from mild paresthesias to debilitating numbness and intrinsic atrophy. Commonly, the classification of severity relies on clinical symptoms and slowing of conduction velocity across the elbow. However, changes in compound muscle action potential (CMAP) amplitude more accurately reflect axonal loss.

The 7 Structures Distal to the Elbow That Are Critical to Successful Anterior Transposition of the Ulnar Nerve.

Ulnar nerve transposition (UNT) surgery is performed for the treatment of cubital tunnel syndrome. Improperly performed UNT can create iatrogenic pain and neuropathy. The aim of this study is to identify anatomical structures distal to the medial epicondyle that should be recognized by all surgeons performing UNT to prevent postoperative neuropathy.

Protein profiling of the dimorphic, pathogenic fungus, Penicillium marneffei.

Background: Penicillium marneffei is a pathogenic fungus that afflicts immunocompromised individuals having lived or traveled in Southeast Asia. This species is unique in that it is the only dimorphic member of the genus. Dimorphism results from a process, termed phase transition, which is regulated by temperature of incubation.
