Carpal Tunnel Syndrome (CTS) is the most common form of entrapment neuropathy. Several authors have investigated the anatomical and pathophysiological features of CTS and have identified several parameters that, in combination, play a significant role in its pathophysiology. Advancement in biological research on CTS has enabled the advent of efficient diagnostic techniques such as provocative tests and nerve conduction studies. Sophisticated technologies, such as magnetic resonance imaging (MRI) and ultrasonography (US), have facilitated the diagnosis of CTS...

Over the past two decades there have been significant advances in the use of magnetic resonance imaging (MRI) to assess the vascular system. New imaging sequences and improvements in magnet design have enabled the creation of higher spatial resolution images. MRI is now a viable alternative imaging modality when compared to both invasive angiography and computed tomographic angiography. The use of blood pool agents has further facilitated the use of MR angiography (MRA); their high molecular weight allows for lower doses of contrast medium administration while their prolonged presence in the blood stream allows for repeated high-quality volumetric imaging of both the arterial and venous circulation...

The cubital region of the arm is a common site for recording blood pressure, taking blood for analysis and administering intravenous therapy and blood transfusions. During the routine dissection of a 70-year-old male cadaver at the Kasturba Medical College, Manipal, Karnataka, India, in 2015, it was observed that the aponeurotic insertion of the biceps brachii muscle divided into two slips. The medial slip fused normally with the deep fascia of the forearm, while flexor carpi radialis muscle fibres originated from the lateral slip...

BACKGROUND: Anterior cutaneous nerve entrapment syndrome (ACNES) is a neuropathic abdominal wall pain syndrome typically characterized by locally altered skin sensations. On the other hand, visceral disease may also be associated with similar painful and altered skin sensations ("Head zones"). Aim of the study was to determine if patients with acute appendicitis demonstrated somatosensory disturbances in the corresponding right lower quadrant Head zone. METHODS: The presence of somatosensory disturbances such as hyperalgesia, hypoesthesia, altered cool perception, or positive pinch test was determined in 100 patients before and after an appendectomy...

PURPOSE: Extra-articular hip impingement syndromes encompass a group of conditions that have previously been an unrecognised source of pain in the hip and on occasion been associated with intra-articular hip impingement as well. As arthroscopic techniques for the hip continue to evolve, the importance of these conditions has been recognised recently and now form an important part of the differential of an individual presenting with hip pain. The aim of this article, therefore, is to provide the reader with an evidence-based and comprehensive update of these syndromes...

BACKGROUND: Carpal tunnel syndrome (CTS) is the most common peripheral entrapment neuropathy. Limited incision techniques for carpal tunnel release are gaining popularity. The main advantages of these techniques are less scar load, less pillar pain, shorter recovery, and return-to-work time. However, the completeness of release, and risk of neurovascular injury are always a concern. We devised a method of limited incision release with two mini-incisions and use of nasal speculum and a probe...

BACKGROUND: Compressive neuropathy of the ulnar nerve at the elbow, or cubital tunnel syndrome (CuTS), is the second most common entrapment neuropathy of the upper extremity after carpal tunnel syndrome. While several studies have reported risk factors and outcomes for select populations (mostly surgical), it is difficult to interpret these data without an accurate measure of CuTS disease burden in the general population. OBJECTIVE: To estimate the incidence of CuTS among US health plan enrollees, using a large administrative health care claims database comprised of individuals from all 50 states...

BACKGROUND: Complex surgery for appearance change is controversial. Correction of orbital hypertelorism risks diplopia and loss of stereopsis for aesthetic gain. The risk-to-benefit ratio remains ill-defined. The aim of this study was to define specific ocular morbidity following orbital translocation. METHODS: The authors compared stable preoperative and postoperative orthoptic indices (i.e., angle of strabismus, ocular motility, and acuity) for 23 consecutive patients who underwent orbital translocation between 2000 and 2015 and noted the requirement for corrective surgery...

INTRODUCTION: In the precise localization of ulnar neuropathy at the elbow (UNE) we have noted discrepancies between electrodiagnostic (EDx) and ultrasonographic (US) findings. We aimed to explore the relationship between the 2 methods. METHODS: Four study-blind examiners took a history and performed neurologic, EDx, and US examinations of a group of prospectively recruited patients with UNE. They assessed the relationship between ulnar nerve cross-sectional area (CSA) and motor nerve conduction velocity (MNCV)...

Most patients with chronic back pain suffer from degenerative thoracolumbovertebral disease. However, the following case illustrates that a localized peripheral nerve entrapment must be considered in the differential diagnosis of chronic back pain. We report the case of a 26-year-old woman with continuous excruciating pain in the lower back area. Previous treatment for nephroptosis was to no avail. On physical examination the pain was present in a 2 x 2 cm area overlying the twelfth rib some 4 cm lateral to the spinal process...

Pudendal neuralgia (PN) is a result of pudendal nerve entrapment or injury, also called "Alcock syndrome." Pain that develops is often chronic, and at times debilitating. If conservative measures fail, invasive treatment modalities can be considered. The goal of this case report is to add to a small body of literature that a pulsed radiofrequency (PRF) ablation can be effectively used to treat PN and to show that high resolution MR neurography imaging can be used to detect pudendal neuropathy. CASE PRESENTATION: We present a case of a 51-year-old woman with 5 years of worsening right groin and vulva pain...

Carpal tunnel syndrome is the most common entrapment neuropathy, affecting the median nerve at the wrist. Acupuncture is a minimally-invasive and conservative therapeutic option, and while rooted in a complex practice ritual, acupuncture overlaps significantly with many conventional peripherally-focused neuromodulatory therapies. However, the neurophysiological mechanisms by which acupuncture impacts accepted subjective/psychological and objective/physiological outcomes are not well understood. Eligible patients (n = 80, 65 female, age: 49...

PURPOSE: Carpal tunnel syndrome (CTS) is a common entrapment neuropathy of the wrist. The diagnosis of CTS has been a concern for physicians for a long time. The aim of this study is to evaluate the use of the median nerve (MN) cross-sectional area (CSA) in the wrist compared with the CSA in the forearm to grade the severity of CTS in Egyptian patients. METHODS: The CSAs of the MN in the wrist and forearm were measured in 72 wrists that were diagnosed with CTS via nerve conduction studies and 80 healthy wrists...

Nerve entrapment syndromes in the upper extremities are common clinical disease patterns, less often as direct results of accidents. The most frequent compression syndrome is the carpal tunnel syndrome followed by the cubital tunnel syndrome. If the cause of the compression cannot be eliminated by conservative treatment options, an operative therapy is necessary. As the prognosis becomes worse with the duration of the nerve compression, it is important to initiate therapy at an early stage.

BACKGROUND: Chronic abdominal pain in children may be caused by the anterior cutaneous nerve entrapment syndrome. Local nerve blocks are recommended as an initial treatment in adults. Evidence on effectiveness and safety of such a treatment in children is lacking. AIM: Our aim was to study outcome and adverse events of anterior rectus sheath blocks in childhood anterior cutaneous nerve entrapment syndrome. METHODS: Patients <18 years of age receiving anterior rectus sheath blocks were prospectively followed...

An approximately 22 mo old male neutered English bulldog was evaluated for acute onset of dyspnea with suspected brachycephalic obstructive airway syndrome (BOAS). Laryngoscopic exam revealed diffuse, severe edema and static displacement of redundant glossoepiglottic (GE) mucosa causing complete obstruction of the larynx and epiglottic entrapment. Static displacement of the GE mucosa was observed and determined to be the overriding component of dyspnea in this patient with BOAS. Resection and primary closure with two separate, simple continuous sutures of the GE mucosa were performed...

BACKGROUND: Severely displaced supracondylar fractures of the humerus in children are frequently associated with complications including neurovascular injuries, non-union, or compartment syndrome. In the current literature, no report exists about postoperative brachial artery entrapment in combination with an inconspicuous preoperative neurovascular examination. CASE PRESENTATION: We present a case of a 6-year-old white boy with a pulseless radial and ulnar artery after open reduction and internal fixation of a severely displaced supracondylar fracture of his right humerus (Gartland type III) using four K-wires...

The Ehlers-Danlos syndromes (EDS) are a heterogeneous group of heritable connective tissue disorders characterized by joint hypermobility, skin extensibility, and tissue fragility. This communication briefly reports upon the neurological manifestations that arise including the weakness of the ligaments of the craniocervical junction and spine, early disc degeneration, and the weakness of the epineurium and perineurium surrounding peripheral nerves. Entrapment, deformation, and biophysical deformative stresses exerted upon the nervous system may alter gene expression, neuronal function and phenotypic expression...
