Acute median nerve compression usually occurs from increased pressure within the carpal tunnel and forearm compartments. Although the hyperesthesia from burns may mimic symptoms of acute compression neuropathy, clinical diagnosis should be made from history, clinical signs and symptoms. Early recognition and decompression of the carpal tunnel either as part of the burn excision or along with es...

Ganglions are the most frequently seen soft-tissue tumors in the hand. Nerve compression due to ganglion cysts at the wrist is rare. We report 2 ganglion cysts arising from triangular fibrocartilage complex, one of which caused ulnar nerve compression proximal to the Guyon's canal, leading to ulnar neuropathy. Ganglion cysts seem unimportant, and many surgeons refrain from performing a general ...

Nerve compression syndromes commonly involve the nerves in the upper extremity. High-resolution ultrasonography (US) can satisfactorily assess these nerves and may detect the morphological changes of the nerves. US can also reveal the causes of nerve compression when structural abnormalities or space-occupying lesions are present. The most common US finding of compression neuropathy is nerve sw...

Sciatic neuropathy is the second most common neuropathy of the lower extremity and a common cause of foot drop. This article reviews the anatomy, clinical features, pathophysiology, and electrodiagnostic assessment of sciatic neuropathies. There are multiple potential sites of pathology, determined in part by the mechanism of insult, including trauma, compression, masses, inflammation, and vasc...

Vascular injuries after total knee arthroplasty are uncommon but they can result in serious complications and poor clinical outcome. Early diagnosis and accurate management are important to achieve the best possible result, so postoperative vascular surveillance is advisable, specially with associated risk factors. Although the presence of neuropathy secondary to compression by an expanding pse...

Peroneal or fibular neuropathy is the most frequent mononeuropathy encountered in the lower limb. In this article, the causes, clinical features, electrodiagnostic assessment, and the treatment of peroneal neuropathies are described. Numerous causes have been reported to result in peroneal neuropathies, with mechanisms including compression, stretch, surgery, or trauma. Electrodiagnostics have ...

We present three patients with signs and symptoms of meralgia paresthetica (MP) after long-distance walking and cycling. No other possible causes of MP, such as trauma or exogenous compression, were present. A neuropathy of the lateral femoral cutaneous nerve was confirmed in all patients with somatosensory evoked potentials. We propose that conduction block due to local ischemia during repetit...

Ulnar tunnel syndrome could be broadly defined as a compressive neuropathy of the ulnar nerve at the level of the wrist. The ulnar tunnel, or Guyon's canal, has a complex and variable anatomy. Various factors may precipitate the onset of ulnar tunnel syndrome. Patient presentation depends on the anatomic zone of ulnar nerve compression: zone I compression, motor and sensory signs and symptoms; ...

Median nerve neuropathy following an elbow injury is uncommon. When it occurs, understanding the median nerve distribution and anatomy is crucial for identifying the cause and for distinguishing cases that can be managed with observation as opposed to intervention. The consequences of misdiagnosis can result in permanent disability. Understanding the mechanisms of nerve injury will help the cli...

fibrolipomatous hamartoma of nerve (neural fibrolipoma) is a tumor-like lipomatous process principally involving young persons. the median nerve is most commonly affected. the lesion is characterized by a soft slowly growing mass surrounding and infiltrating major nerves and their branches. it may cause symptoms of compression neuropathy and is associated with macrodactyly in one third of cases...
