Introduction: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy of the upper extremity. It is usually associated with the compression of the median nerve in the median groove. Because the main symptoms of CTS pain and numbness worsen at night, sleep disorders in CTS patients and the impact of preferred sleeping position on CTS development have been formerly studied. However, to the best of our knowledge, this is the first study assessing the frequency of CTS in obstructive sleep apnea (OSA) patients...

Background and Aim: Pure sensory neuropathies involving the dorsal root ganglia are commonly referred to as sensory ganglionopathies (SG). Causes of SG can be inherited (as seen in Friedreich's ataxia) or acquired (e.g. immune-mediated or paraneoplastic). Diagnostic criteria for confirming SG have been published and consist of a combination of clinical and neurophysiological parameters. The aim of our study was to develop a neurophysiological method for rapid screening for diagnosis of SG...

Meralgia paresthetica is a neuropathic pain disorder resulting from an entrapment neuropathy of the lateral femoral cutaneous nerve. This condition results in pain, paresthesias and numbness over the anterolateral aspect of the thigh. We present a case of meralgia paresthetica and discuss both the clinical and histopathological findings as they relate to one another. We report a case of meralgia paresthetica refractory to conservative treatment who underwent neurectomy with successful treatment of symptoms...

INTRODUCTION: Although ganglion cysts are common soft tissue tumors, nerve compression syndrome caused by a ganglion cyst in the lower extremities is very rare. Herein, we report a 57-year-old man who presented with hypoesthesia in the sole of his right foot for 6 months. We believe that reporting this rare case will help clinicians update their knowledge on possible causes of the plantar neuropathy, and avoid diagnostic delay. PRESENTATION OF CASE: The patient had pain and numbness in the inner right sole, as well as a tingling and dull sensation...

Notalgia paresthetica (NP) is an underdiagnosed condition that presents with unilateral pruritus medial to the scapula on the midback with or without an associated hyperpigmented or hypopigmented macule. There is a paucity of recent reviews on this chronic cutaneous neuropathy in peer-reviewed journals. Current theories propose the condition is likely multifactorial, including spinal entrapment and muscular compressive neuropathy. An extensive literature review was performed by searching the MEDLINE database to review all published works on notalgia paresthetica...

PURPOSE: The mucolipidoses are rare autosomal recessive lysosomal storage disorders. Neurologic involvement in these conditions is generally thought to be limited to cognitive delay and entrapment neuropathies (primarily carpal tunnel syndrome). We sought to evaluate peripheral nerves in this condition using nerve ultrasound. METHODS: We performed peripheral nerve ultrasound in two siblings with genetically confirmed mucolipidosis type 3 (alpha/beta). RESULTS: Peripheral nerves in mucolipidosis type 3 (alpha/beta) exhibit multifocal enlargement...

Entrapment neuropathy is the result of pressure on a peripheral nerve as it passes through a narrow canal that is bounded by stiff tissues. In spite of their ubiquitous nature, they are underdiagnosed, underreported, and sometimes not properly managed, especially in developing countries. Entrapment neuropathies are of various types, but the most common type is carpal tunnel syndrome. Mechanisms involved in the pathophysiology of entrapment neuropathies include mechanical compression and nerve ischemia. A clear understanding of the various types and the underlying mechanisms of entrapment neuropathies are invaluable in the decision-making process involved in the management of every patient with the condition...

Spinobulbar muscular atrophy (SBMA) is an X-linked recessive disease, presenting motor weakness and wasting of facial, bulbar and limb muscles. Hereditary neuropathy with liability to pressure palsy (HNPP) is autosomal dominant disorder characterized by recurrent neuropathies at common entrapment sites. We report a case of co-existence of SBMA and atypical HNPP with genetic confirmation of CAG expansion in the androgen receptor (AR) gene and deletion of the peripheral myelin protein 22 (PMP22) gene. A 62-year-old man presented with progressive muscle weakness, fasciculations in upper and lower limbs and dysesthesia predominantly in the distal regions...

Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy occurring in upper limbs. The etiology, however, has not been fully understood yet. Median nerve could be compressed by either increase of carpal tunnel pressure (CTP) or direct impingement when it is forced toward to carpal ligament especially in wrist flexion leading to CTS development. Thus, the increase of carpal tunnel pressure is considered an important role in CTS development. It has been identified that forces applied to the palm would affect the CTP...

OBJECTIVE: Nerve ultrasound (US) data on myelin protein zero (MPZ)-related Charcot-Marie-Tooth disease (CMT) are lacking. To offer a comprehensive perspective on MPZ-related CMTs, we combined nerve US with clinics, electrodiagnosis and histopathology. METHODS: We recruited 36 patients (12 MPZ mutations), and correlated nerve US to clinical, electrodiagnostic measures, and sural nerve biopsy. RESULTS: According to motor nerve conduction velocity (MNCV) criteria, nine patients were categorized as "demyelinating" CMT1B, 17 as "axonal" CMT2I/J, and 10 as dominant "intermediate" CMTDID...

INTRODUCTION: We studied the clinical and nerve pathologic features in 6 patients whose low back pain (LBP) was relieved by superior cluneal nerve (SCN) neurectomy to determine whether nerve compression was the mechanism underlying this type of LBP. METHODS: All 6 patients (7 nerves) underwent SCN neurectomy for intractable LBP. Their clinical outcomes and the pathologic features of 7 nerves were reviewed. RESULTS: All patients reported LBP relief immediately after SCN neurectomy...

Intraosseous entrapment of the median nerve is an uncommon complication of elbow dislocation and fractures. The condition is seen to occur in adolescent age group with a remote history of trauma. We report two rare cases of type 2 intraosseous median nerve entrapment. Though the diagnosis of median neuropathy is made with clinical tests and neurophysiological studies, however exact site of entrapment and presurgical mapping of nerve is done accurately with MR neurography. Imaging thus plays a pivotal role in management of this condition...

Diffusion tensor imaging (DTI) is a noninvasive magnetic resonance imaging (MRI) technique that measures the extent of restricted water diffusion and anisotropy in biological tissue. Although DTI has been widely applied in the brain, more recently researchers have used it to characterize nerve pathology in the setting of entrapment neuropathy, traumatic injury, and tumor. DTI artifacts are exacerbated when imaging off isocenter in the body. Anecdotally, the most significant artifacts in peripheral nerve DTI include magnetic field inhomogeneity, motion, incomplete fat suppression, aliasing, and distortion...

BACKGROUND: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy of the upper limb. Research has shown that associative factors for CTS include occupational and biomechanical elements, gender, and age. To date, no systematic review has been undertaken to determine specifically whether there are any psychosocial risk factors in developing CTS. The objective is to determine whether psychosocial factors are associated with and/or predict the development of CTS. METHODS: A systematic review was conducted including searches of PubMed (MEDLINE), EMBASE, and CINAHL from inception to May 30, 2017...

BACKGROUND: There is still debate whether the surgical release of entrapped lower extremity nerves reduces complaints of associated neuropathy and results in gain of sensory function. The aim of this study is to investigate which factors are associated with a favorable surgical outcome, by follow-up of patients previously participating in a randomized controlled trial. METHODS: We evaluated the 5-years follow-up of diabetic patients previously participating in the Lower Extremity Nerve entrapment Study (LENS)...

Painful neuropathies can be caused by nerve compression or neuromas. Nerve compressions can arise from scar adhesions causing painful posttraumatic entrapment of nerve branches via fibrosis. The classical treatment methods include neurolysis and nerve transposition. In this case, we present the treatment of recurrent scar entrapment of the saphenous nerve with percutaneous neurolysis and lipofilling in a patient who had previously undergone an open neurolysis procedure. Resolution of the condition without any complications was noted during the 2-month clinical follow-up...

Paraneurial adhesions have been implicated in the pathological progression of entrapment neuropathies. Surgical decompression of adhesions is often performed, with the intent of restoring nerve kinematics. The normal counterpart of adhesions, native paraneurium, is also thought to influence nerve deformation and mobility. However, influences of native or abnormal paraneurial structures on nerve kinematics have not been investigated. We measured regional strains in rat sciatic nerves before and immediately after decompression of native paraneurial tissue, and before and after decompression of abnormal paraneurial adhesions, which formed within 6 weeks of the initial decompression...
