Radial nerve and posterior interosseous nerve decompression

Front of the forearm exposed and prepared for surgery (note - as often there is nothing abnormal to see on the outside)

MRI scan pictures show possible posterior interosseous nerve entrapment

Incision marked

Incision started

Incision to the superficial fascia (fibrous layer surrounding the forearm muscles)

Fascial layer divided to expose the underlying muscles

Superficial sensory branch of the radial nerve exposed

Vascular leash (group of veins) seen overlying the deep branch of the radial nerve - the posterior interosseous nerve

Short area of narrowing (stenosis) found in the posterior interosseous nerve

Careful proximal dissection of the radial nerve to ensure no other areas of entrapment

Wound closed with an absorbable stitch
