INTRODUCTION: Familial amyloid polyneuropathy (FAP) is a rare hereditary disorder caused by mutations in the transthyretin (TTR) gene. Tafamidis is a TTR stabilizer able to prevent TTR tetramer dissociation, and several studies have demonstrated its safety and efficacy at slowing the progression of neuropathy in FAP caused by the TTR Val30Met mutation. However, nerve conduction study (NCS) and electromyography (EMG) results have yet to be reported in relation to FAP progression during tafamidis therapy...

Nerve entrapment syndromes occur because of anatomic constraints at specific locations in both upper and lower limbs. Anatomical locations prone to nerve entrapment syndromes include sites where a nerve courses through fibro-osseous or fibromuscular tunnels or penetrates a muscle. The median nerve (MN) can be entrapped by the ligament of Struthers; thickened biceps aponeurosis; between the superficial and deep heads of the pronator teres muscle and by a thickened proximal edge of flexor digitorum superficialis muscle...

INTRODUCTION: Charcot-Marie-Tooth Disease type 1 C (CMT1C) is a rare, dominantly inherited neuropathy caused by mutations in the lipopolysaccharide-induced tumor necrosis factor (LITAF) or small integral membrane protein of the lysosome/late endosome (SIMPLE) gene. METHODS: We present a case series comprised of 10 patients in whom CMT1C is caused by a Gly112Ser substitution in the encoded protein. We focus on clinical presentation, electrodiagnostic analyses, and our findings in the context of previously described cases...

OBJECTIVES: To explore clinical-neurophysiological correlations in anti-myelin-associated glycoprotein (anti-MAG) neuropathy. METHODS: Clinical and electrophysiological data of 42 patients with anti-MAG neuropathy were retrospectively analysed. Disability was evaluated using the Overall Neuropathy Limitation Scale (ONLS), motor impairment through MRC sum score and sensory deficiency through INCAT sensory score. Compound motor action potential (CMAP) sum score was calculated adding the distal CMAP amplitude of the median, ulnar, tibial and fibular nerves of both sides...

BACKGROUND: Myotonic dystrophy (DM) type 1 and type 2 are inherited diseases characterized by myotonia and myopathy. Additional symptoms include, among others, peripheral neuropathy and sleep-related breathing disorders (SRBDs). There is growing evidence for a complex association between DM1 and DM2, which was described in patients with diabetes mellitus and in the general population. In this study, we investigated whether there is an association between peripheral neuropathy and SRBDs also in the population of patients with DM...

BACKGROUND: Posttraumatic elbow contractures in children and adolescents are challenging to manage, and studies investigating surgical treatment are limited by the rarity of this condition. Small case series have shown variable gains in immediate and long-term elbow arc of motion after open surgical release. We reviewed our experience with open surgical release of posttraumatic elbow contracture in patients <21 years old at 2 institutions. METHODS: A retrospective chart review identified patients who underwent posttraumatic open elbow contracture release by 2 surgeons at 2 institutions between 2006 and 2013...

BACKGROUND: Dislocation of the ulnar nerve (UN) occurs in a subset of patients with ulnar neuropathy. Electrodiagnostic and magnetic resonance imaging (MRI) studies are performed to support the clinical diagnosis. We report the case of a patient with ulnar neuropathy with normal electrodiagnostic and MRI studies but with ultrasonography (US) showing UN dislocation, which prompted successful treatment by UN submuscular transposition. CASE DESCRIPTION: A healthy 15-year-old female softball player presented with right medial elbow pain and paresthesias of the fourth and fifth digits...

CLINICAL/METHODICAL ISSUE: Up to the advent of high-resolution ultrasound, interventions on the peripheral nervous system, including local anesthesia and pain treatment were performed without visual guidance, which in some cases led to treatment failure or local tissue and nerve damage. METHODICAL INNOVATIONS: Progress in the field of ultrasound has enabled the functional visualization, anesthesia and anti-inflammatory or neurolytic treatment of many peripheral nerves, such as the brachial plexus, nerves of the upper and lower extremities and various nerves of the trunk...

PURPOSE: The management of distal radius fractures differs based on the nature of the fracture and the experience of the surgeon. We hypothesized that patients requiring surgical intervention would undergo different procedures when in the care of a surgeon with subspecialty training in hand surgery as compared with surgeons with no subspecialty training in hand surgery. METHODS: We queried the ABOS database for case log information submitted for part II of the ABOS examination...

INTRODUCTION: Multifocal sensory demyelinating neuropathy has not been reported. METHOD: A 42-year-old man with numbness of the left hand for 3 years and of the right hand for 6 months had a pure multifocal sensory neuropathy involving both hands, most prominently affecting 2-point discrimination, number writing, and object recognition in the left hand. Near-nerve needle sensory and mixed nerve conduction studies were performed in the left ulnar nerve. RESULTS: Studies of the left ulnar nerve documented a demyelinating neuropathy characterized by temporal dispersion and marked decrease in the amplitudes of the sensory and mixed compound nerve potentials in the above elbow-axilla segment...

Diagnosis of carpal tunnel syndrome (CTS) is frequently confirmed by performing nerve conduction studies. Previous studies demonstrated that abnormal nerve conduction study (NCS) is suggestive of CTS among asymptomatic individuals. However, previous studies included individuals with risk factors for the syndrome. A NCS was performed on the median and ulnar nerves in 130 healthy individuals. About 15% of individuals in this study demonstrated electrodiagnostic evidence of carpal tunnels syndrome. Four cases have shown signs of isolated median neuropathy with normal median sensory component...

Despite its low prevalence and incidence, considerable debate exists in the literature on thoracic outlet syndrome (TOS). From literature analysis on nerve entrapments, we realized that TOS is the second most commonly published entrapment syndrome in the literature (after carpal tunnel syndrome) and that it is even more reported than ulnar neuropathy at elbow, which, instead, is very frequent. Despite the large amount of articles, there is still controversy regarding its classification, clinical picture, diagnostic objective findings, diagnostic modalities, therapeutical strategies and outcomes...

A 60-year-old Nigerian man, who had lived in Europe for 30 years but had returned home frequently, presented with right frontalis muscle weakness and right ulnar nerve palsy, without skin lesions. Neurophysiology showed a generalised neuropathy with demyelinating features. Blood tests were positive for HIV, with a normal CD4 count. There was nerve thickening both clinically and on MRI. Nerve biopsy showed chronic endoneuritis and perineuritis (indicating leprosy) without visible mycobacteria. His neuropathy continued to deteriorate (lepra reaction) before starting treatment with WHO multidrug therapy, highly active antiretroviral therapy and corticosteroids...

In addition to the more common carpal tunnel and cubital tunnel syndromes, orthopaedic surgeons must recognize and manage other potential sites of peripheral nerve compression. The distal ulnar nerve may become compressed as it travels through the wrist, which is known as ulnar tunnel or Guyon canal syndrome. The posterior interosseous nerve may become entrapped in the proximal forearm as it travels through the radial tunnel, which results in a pain syndrome without motor weakness. The median nerve may become entrapped in the proximal forearm, which can result in a variety of symptoms...

REVIEW
Jacob W Brubacher, Fraser J Leversedge
The form and function of the cyclist exposes the ulnar nerve to both traction and compressive forces at both the elbow and wrist. Prevention of ulnar neuropathy and treatment of early symptoms include bike fitting, avoidance of excessive or prolonged weight-bearing through the hands, and the use of padded gloves. For persisting or progressive symptoms, a thorough history and physical examination is essential to confirm the diagnosis and to rule out other sites of nerve compression. The majority of compression neuropathies in cyclists resolve after appropriate rest and conservative treatment; however, should symptoms persist, nerve decompression may be indicated...

INTRODUCTION: Ulnar neuropathy at the elbow (UNE) is a common peripheral compression neuropathy and in most cases occurs at 2 sites, the retroepicondylar groove or the cubital tunnel. With regard to a potential therapeutic approach with perineural corticosteroid injection the aim of this study was to evaluate the distribution of injection fluid applied at a standard site. METHODS: We performed ultrasound-guided (US-guided) perineural injections to the ulnar nerve halfway between the olecranon and the medial epicondyle in 21 upper limbs from 11 non-embalmed cadavers...
