Sonographic Diagnosis Of Posterior Interosseous Nerve Entrapment Syndrome
نویسندگان
چکیده
Posterior interosseous nerve entrapment is a potential cause of upper extremity muscle weakness and pain. The diagnosis may be difficult to make clinically, and electrodiagnostic tests may not identify the exact site of nerve compression. We report a case of posterior interosseous nerve entrapment in which electrodiagnostic studies suggested radial neuropathy at the level of the spiral groove, but the sonographic evaluation pinpointed the arcade of Frohse as the level of compression. The patient's symptoms improved dramatically following surgical release of the nerve. Sonography may be a valuable, non-invasive diagnostic tool in evaluating patients with posterior interosseous nerve entrapment.

Entrapment of the posterior interosseous nerve at the arcade of Frohse with sonographic, magnetic resonance imaging, and intraoperative confirmation.
ntrapment of the radial nerve, specifically the deep branch of the radial nerve (DBRN) in the arcade of Frohse, was first described in 1963.1 Prolonged entrapment may lead to a constellation of symptoms described in posterior interosseous nerve (PIN) paralysis.2 Reported attempts at diagnosis using imaging have mostly involved magnetic resonance imaging (MRI), with a limited number of studies c...

Between 1371 to 1379, of 10 patients with radial tunnel syndrome, 9 patients were treated by decompression of the posterior interosseous nerve. 8 patients were followed up more than 10 months. One patient improved without surgery. Half of the patients suffered from pain and all of them had variable degrees of paralysis in muscles innervated by deep branch of the radial nerve. The syndrome was d...

OBJECTIVES The purpose of this study was to determine whether sonography can identify the distal posterior interosseous nerve at the wrist. METHODS On the basis of previous anatomic descriptions, high-resolution musculoskeletal sonography was used in an attempt to identify the distal posterior interosseous nerve in the wrists of 20 unembalmed cadaveric specimens (11 male and 9 female; ages 54...

Ultrasound (US) is one of the methods for imaging entrapment neuropathies, post-traumatic changes to nerves, nerve tumors and postoperative complications to nerves. This type of examination is becoming more and more popular, not only for economic reasons, but also due to its value in making accurate diagnosis. It provides a very precise assessment of peripheral nerve trunk pathology - both in t...
