Nerve compression and entrapment syndromes are classic examples of the integrated role of radiologists and clinicians in achieving difficult but accurate diagnoses. The pathology of nerves can only be understood after evaluating the normal architecture and imaging characteristics of nerves. Understanding the correlation of the pathophysiology of nerve compromise with electromyographic findings and imaging findings allows for greater comprehension of a difficult topic. Particularly in the elbow, there are multiple potential areas of nerve entrapment and compression that can be evaluated perhaps best with magnetic resonance imaging.

Suprascapular nerve compression is a rare but important entity that is often missed in clinical practice. Nerve dysfunction caused by an intraosseous ganglion of the glenoid is extremely rare, to the ...
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 ...
To identify sensory branches of the ulnar nerve - palmar ulnar cutaneous nerve (PUCN), dorsal ulnar cutaneous nerve (DUCN), and superficial sensory branch - using ultrasonography.
To assess the causes, surgical indications, patient-reported clinical outcomes, and complications in patients with deep gluteal syndrome causing sciatic nerve entrapment.
10-30% of chronic abdominal pain originates in the abdominal wall. A common cause for chronic abdominal wall pain is the Anterior Cutaneous Nerve Entrapment Syndrome (ACNES), in which an intercostal n...
Ulnar neuropathy at elbow (UNE) is the second common peripheral entrapment neuropathy. Although many conservative managements of UNE, the effectiveness of these methods are unsatisfied esp...
Neuralgic pain caused by entrapment of peripheral nerves is an often overlooked cause of chronic pelvic pain. The objective of the present study was to assess pain and quality of life in w...
There is currently no consensus on the normal ultrasound surface of the ulnar nerve at the elbow. The goal of this study is to study the ulnar nerve surface at the elbow in a population of...
Ulnar nerve compression at the elbow is a common problem and can significantly affect hand function in severe cases. The current, standard treatment is Ulnar nerve decompression with or wi...
The investigators want to compare changes in cross-sectional area (CSA) of the ulnar nerve at the elbow after open release or endoscopic release.
Mechanical compression of nerves or nerve roots from internal or external causes. These may result in a conduction block to nerve impulses (due to MYELIN SHEATH dysfunction) or axonal loss. The nerve and nerve sheath injuries may be caused by ISCHEMIA; INFLAMMATION; or a direct mechanical effect.
Conditions in which increased pressure within a limited space compromises the BLOOD CIRCULATION and function of tissue within that space. Some of the causes of increased pressure are TRAUMA, tight dressings, HEMORRHAGE, and exercise. Sequelae include nerve compression (NERVE COMPRESSION SYNDROMES); PARALYSIS; and ISCHEMIC CONTRACTURE.
Compression of the ULNAR NERVE in the cubital tunnel, which is formed by the two heads of the flexor carpi ulnaris muscle, humeral-ulnar aponeurosis, and medial ligaments of the elbow. This condition may follow trauma or occur in association with processes which produce nerve enlargement or narrowing of the canal. Manifestations include elbow pain and PARESTHESIA radiating distally, weakness of ulnar innervated intrinsic hand muscles, and loss of sensation over the hypothenar region, fifth finger, and ulnar aspect of the ring finger.

Ulnar neuropathies caused by mechanical compression of the nerve at any location from its origin at the BRACHIAL PLEXUS to its terminations in the hand. Common sites of compression include the retroepicondylar groove, cubital tunnel at the elbow (CUBITAL TUNNEL SYNDROME), and Guyon's canal at the wrist. Clinical features depend on the site of injury, but may include weakness or paralysis of wrist flexion, finger flexion, and ulnar innervated intrinsic hand muscles, and impaired sensation over the ulnar aspect of the hand, fifth finger, and ulnar half of the ring finger.
