Targeted Muscle Reinnervation to Lumbrical Muscles for Symptomatic Digital Stump Neuroma: Surgical Technique

Targeted muscle reinnervation (TMR) represents a significant advancement in treating symptomatic stump neuromas. Unlike traditional passive procedures, TMR redirects axonal growth from sensory nerves to motor endplates, which may help prevent neuroma recurrence. This study detailed the surgical steps involved in applying TMR to the lumbrical muscles, supported by graphic, photographic, and video illustrations, aiming to ensure reproducibility.
