Summary
Radiofrequency (RF) neurotomy effectively treats spasticity in the adductor and gastrocnemius muscles. This minimally invasive procedure uses targeted nerve ablation to reduce muscle tightness and improve mobility.
Area of Science:
- Neurology
- Neurosurgery
- Pain Management
Background:
- Spasticity in the femoral adductor and gastrocnemius muscles significantly impacts mobility and quality of life.
- Percutaneous selective radiofrequency (RF) neurotomy offers a minimally invasive approach to target specific nerves causing spasticity.
Observation:
- A temperature monitoring needle electrode system with a 5 mm noninsulated tip was utilized for precise nerve localization via stimulation.
- Percutaneous obturator neurotomy was performed proximally, and posterior tibial neurotomy targeted branches innervating the gastrocnemius muscle.
- Effectiveness was preliminarily assessed by nerve infiltration with local anesthetics in one case.
Findings:
- Four RF lesions, each lasting 60 seconds, were created in different directions (65-70 degrees) to ablate targeted nerves.
- The procedure demonstrated potential for selective nerve targeting in managing spasticity.
Implications:
- Percutaneous RF neurotomy presents a viable therapeutic option for focal spasticity, potentially reducing the need for more invasive interventions.
- Further research is warranted to establish long-term efficacy and refine procedural techniques for optimal patient outcomes in spasticity management.
