Cryoneurolysis of the Femoral Nerve for Focal Spasticity in an Ambulatory Patient

Introduction: Spasticity of the knee extensors is a common presentation among patients with multiple sclerosis. The resulting stiff leg gait can result in increased risk of falls, heightened energy expenditure during gait, lowered gait speed, and compensatory gait mechanisms that increase wear on th...

description Introduction: Spasticity of the knee extensors is a common presentation among patients with multiple sclerosis. The resulting stiff leg gait can result in increased risk of falls, heightened energy expenditure during gait, lowered gait speed, and compensatory gait mechanisms that increase wear on the hips. Cryoneurolysis is a novel percutaneous, minimally invasive treatment for focal spasticity. Methods: A single patient with multiple sclerosis was treated with cryoneurolysis of the femoral nerve branch to rectus femoris. The patient was followed for 15 months. Spasticity severity, gait speed, and patient reported outcomes were collected at each follow-up. Results: Spasticity severity as per the Modified Ashworth Scale was reduced at 1 month, with change persisting up to 15 months post-procedure. Range of motion as per the Modified Tardieu Scale showed gradual improvement over the 15-month period. Gait speed increased after the procedure from 21.15 seconds to 12.49 seconds for the 10 m walk test 1 month post-procedure, then slowed to baseline after 15 months. The patient's confidence in their gait improved and their independence was maintained throughout the follow-up period. Because of the regression in the 10 m walk test, the patient elected to have the procedure repeated after 15 months. Immediately after the procedure, the 10 m test time improved to 16.20 seconds. Conclusion: Cryoneurolysis of the femoral nerve may be an effective, long-lasting treatment for spasticity causing stiff knee gait in patients with multiple sclerosis.
