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 |
