Case contributed by Maulik S Patel
Diagnosis certain


2 months before the presentation, the patient had the right humerus shaft comminuted fracture with shoulder dislocation. Humerus plating was done. The patient was referred for an ultrasound evaluation for the radial nerve palsy.

Patient Data

Age: 50 years
Gender: Female

There is screw-plate fixation across a comminuted fracture of the humerus shaft. There is no dislocation.


The radial nerve was traced from the proximal arm to wrist level.

The radial nerve is trapped between a humeral fracture fragment and plate in the mid-shaft region. The fragment is about 35 mm long. The adjacent nerve segments show edema with continuity.

There is mild edema of the posterior interosseous nerve and the superficial sensory nerve in proximal forearm without any compression/discontinuity.

This was supplied along with the report for better understanding the abnormality.

The nerve was compressed by the bone fragment. The nerve was mobilized. The compressed segment showed thinning. However, nerve continuity was maintained.
