What is posteriorposterior interosseous nerve syndrome?
Posterior interosseous nerve syndrome is a neuropathic compression of the posterior interosseous nerve, that is situated where this nerve (RN) passes through the radial tunnel(4) (Level of Evidence: 4) . The radial tunnel is a space that extends 5 cm from the radial head to the distal margin of the supinator.
