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...

account for approximately 3% of all biceps tendon ruptures. The two-incision repair techniques, as described by Boyd and Anderson1 in 1961, were developed to lower the risk of injury to the radial nerve and posterior interosseous nerve. Reports of posterior interosseous nerve palsy following this approach are rare.2-3 Transient posterior interosseous nerve palsies following a repair with the tw...

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...

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, ...

In a study of 42 tetraplegic patients, physiological, neurological, electrophysiological and radiological examinations were made in 11 patients with complete tetraplegia who had wrist pain after rehabilitation. Pain relief produced by a selective, posterior interosseous nerve lidocaine block indicated distal posterior interosseous nerve syndrome. This syndrome can sometimes be treated conservat...

Posterior interosseous nerve palsy caused by a ganglion is not common and most previous patients were treated with excisional surgery. We treated a case conservatively with needle aspiration using ultrasonography, after a nerve conduction study. A 77-year-old man presented with impaired active finger extension of the left metacarpophalangeal joints. The nerve conduction study revealed conductio...

INTRODUCTION We report an extremely rare case of tardy posterior interosseous nerve palsy that developed 40 years after unreduced anterior dislocation of the radial head in a Monteggia fracture. CASE PRESENTATION A 46-year-old Asian woman was diagnosed with tardy posterior interosseous nerve palsy resulting from residual dislocation of the radial head in a Monteggia fracture. The patient reme...

variations in arterial anatomy are less frequent, contrary to the venous system, and most of these variations affect visceral arteries. variations in the brachial artery are the most frequently reported and so far a minimum of six different patterns have been described. the most common of these patterns is the superficial brachial artery, which lies superficially to the median nerve. much less ...
