• extensor
  • In other words, it supplies the following muscles: Extensor carpi radialis brevis-deep branch of radial nerve Extensor digitorum Extensor digiti minimi Extensor carpi ulnaris Supinator muscle-deep branch of radial nerve Abductor pollicis longus Extensor pollicis brevis Extensor pollicis longus Extensor indicis The posterior interosseous nerve may be entrapped at the arcade of Frohse, which is part of the supinator muscle. (wikipedia.org)
  • After it emerges out from the radial sulcus, it supplies the brachialis, brachioradialis and extensor carpi radialis longus. (wikipedia.org)
  • This muscle imbalance between the (intact) radial nerve innervated extensor digiti quinti and the (weak) ulnar innervated interossei in the context of ulnar neuropathy is what Wartenberg described. (wikipedia.org)
  • humerus
  • Pollock FH, Drake D, Bovill EG, Day L, Trafton PG (1981) Treatment of radial neuropathy associated with fractures of the humerus. (springer.com)
  • One out of every ten patients suffering from radial nerve dysfunction do so because of a fractured humerus. (wikipedia.org)
  • In the arm, it runs behind the brachial artery and then enters the lower triangular space to reach the radial sulcus of back of the humerus. (wikipedia.org)
  • tunnel syndrome
  • Some speculate that Radial Tunnel Syndrome is a type of repetitive strain injury (RSI), but there is no detectable pathophysiology and even the existence of this disorder is questioned. (wikipedia.org)
  • Therefore, it is extremely important in upper body extremity movement and can cause significant pain to patients presenting with radial tunnel syndrome. (wikipedia.org)
  • repetitive
  • Persistent injury-Persistent injury to the nerve is a common cause through either repetitive motion or by applying pressure externally along the route of the radial nerve as in the prolonged use of crutches or extended leaning on the elbows. (wikipedia.org)
  • focal
  • The mechanism of radial neuropathy is such that it can cause focal demyelination and axonal problems/degeneration (which is nerve fiber reaction to insult, and therefore axon death occurs). (wikipedia.org)
