Ultrasound-Guided Dextrose Hydrodissection for Mixed Sensory-Motor Wartenberg's Syndrome Following a Healed Scaphoid Fracture: A Case Report.

ABSTRACT: Background and Clinical Significance: Wartenberg's syndrome (cheiralgia paresthetica) is classically described as a pure sensory neuropathy of the superficial branch of the radial nerve (SBRN). However, in rare circumstances, dynamic mechanical irritation around the radial styloid may produce an atypical clinical phenotype with concurrent motor impairment, broadening the clinical significance of recognizing motion-related compression mechanisms. Case Presentation: A 35-year-old woman presented with persistent dorsoradial wrist pain and numbness, accompanied by progressive weakness of thumb extension, five years after a conservatively treated nondisplaced scaphoid fracture. Neurological examination demonstrated sensory loss in the SBRN distribution and Medical Research Council
