Release of forearm interosseous palmar nerve entrapment syndrome

The causes of interosseous dorsal nerve entrapment syndrome are multifactorial, and are closely related to local anatomy. When the forearm is fully pronated, the Frohse arch may compress the nerves. Therefore, the dorsal interosseous nerve is relatively fixed there, and the tissues are hard before and after. After forearm rotation, edema, inflammatory swelling, scar tissue formation, or tendon tissue hyperplasia can cause the dorsal interosseous nerve to be compressed at the tendon arch to produce clinical symptoms.
