Background:

Radial nerve palsy frequently occurs after humeral shaft fractures.
Ultrasound-guided hydrodissection is an innovative treatment for nerve entrapment.
Postoperative nerve injury management presents unique challenges.

Observation:

Two cases of radial nerve injury post-humeral shaft fracture with plate fixation were analyzed.
Shear wave elastography identified hardened scar tissue constricting the radial nerve.
These entrapment sites were accurately mapped for targeted intervention.

Findings:

Ultrasound-guided hydrodissection effectively treated radial nerve entrapment caused by scar tissue.
Both patients achieved complete recovery of radial nerve function post-procedure.
Shear wave elastography demonstrated high precision in locating neural compression points.

Implications:

Shear wave elastography can precisely guide hydrodissection for nerve entrapment.
This approach offers a promising solution for complex postoperative neural compression.
Enhanced visualization and targeted treatment improve outcomes for nerve injuries.
