Summary
Selective Femoral Neurotomy (SFN) offers a permanent surgical solution for stiff knee gait caused by quadriceps spasticity. This procedure reduces muscle overactivity, improving knee function during walking.
Area of Science:
- Neurosurgery
- Orthopedics
- Gait Analysis
Background:
- Quadriceps spasticity causes stiff knee gait, limiting knee flexion during the swing phase.
- Selective Femoral Neurotomy (SFN) aims to provide long-term muscle relaxation by reducing the stretch reflex.
Purpose of the Study:
- To evaluate the efficacy of Selective Femoral Neurotomy (SFN) in treating spastic stiff knee gait.
Main Methods:
- Surgical dissection of the femoral nerve trunk below the femoral crease.
- Identification and partial sectioning of motor branches to quadriceps muscles (rectus femoris, vastus intermedius) using EMG and electrical stimulation.
- Individualized preoperative planning and essential postoperative rehabilitation.
Main Results:
- SFN leads to long-term muscle relaxation in the quadriceps.
- Sustained improvements in gait parameters are observed postoperatively with rehabilitation.
Conclusions:
- Selective Femoral Neurotomy (SFN) is an effective, lesion-based surgical treatment for spastic stiff knee gait.
- The procedure offers a permanent solution for improving knee function in affected individuals.
