Ultrasound (US)-Guided Perineural Amniotic Membrane and Umbilical Cord Particulate Injections for Iatrogenic Radial Nerve Palsy.

Radial nerve injury is a common occurrence in the upper extremities, with various treatment options available such as neurolysis, nerve grafts, or tendon transfers. Recently, amniotic membrane and umbilical cord (AM/UC) particulates have emerged as promising treatments for this type of nerve pathology. Here, we report a new case involving a 24-year-old man who experienced total paralysis of the radial nerve following a humerus shaft fracture. He was treated with peri-nerve injections of AM/UC and underwent an intensive physical rehabilitation program. Three months after the initial injury, significant progress was observed in both motor and sensory functions of his radial nerve.
