Nerve Pain Surgery Special Issue
With a rapid expansion of ideas, techniques, and products available for surgical treatments of nerve pain problems, it is data, rigorous investigation, and honest reporting that are critical to ensuring high-quality care. In this special issue we take a broad approach, delving into various aspects of how surgeons manage nerve pain, focusing on harder-to-tell and less-often discussed pieces of this growing puzzle.
High-Transhumeral Amputation: Targeted Muscle Reinnervation and Soft Tissue Coverage With Pedicled Latissimus Dorsi FlapThe introduction of targeted muscle reinnervation has improved amputation pain outcomes and the control of upper-extremity myoelectric prostheses. However, patients with proximal transhumeral amputation levels and soft tissue deficits present a unique challenge. Existing described targeted muscle reinnervation techniques in transhumeral amputees rely on recipient motor nerves from the biceps and triceps; however, these may be absent in patients with more proximal injuries. Here, we describe the use of the pedicled latissimus dorsi flap for both soft tissue coverage and additional motor targets in patients with high-transhumeral amputation with complex soft tissue deficits.
Use of Vascularized, Denervated Muscle Targets for Prevention and Treatment of Upper-Extremity NeuromasNeuroma formation following upper-extremity peripheral nerve injury often results in persistent, debilitating neuropathic pain with a limited response to medical management. Vascularized, denervated muscle targets (VDMTs) offer a newly described surgical approach to address this challenging problem. Like targeted muscle reinnervation and regenerative peripheral nerve targets, VDMTs are used to redirect regenerating axons from an injured nerve into denervated muscle to prevent neuroma formation. By providing a vascularized muscle target that is reinnervated via direct neurotization, VDMTs offer some theoretical advantages in comparison with the other contemporary surgical options.
Treatment of Refractory Radial Sensory Neuroma With Function-Sparing Targeted Muscle Reinnervation to the Extensor Carpi Radialis BrevisThe radial sensory nerve can be injured during many common procedures, including intravenous cannulation, first extensor compartment release, and radial-sided wrist surgery. Injury to the nerve may result in neuroma formation that can lead to chronic and debilitating pain. Nonsurgical treatments and surgical interventions, including excision of the neuroma and burying the nerve into local muscle, are frequently ineffective. Here, we present a technique for treating recalcitrant neuromas of the radial sensory nerve with targeted muscle reinnervation to a redundant motor nerve branch of the extensor carpi radialis brevis.
