Percutaneous Endoscopic Lumbar Foraminoplasty for Lumbar Foraminal Stenosis of Elderly Patients with Unilateral Radiculopathy: Radiographic Changes in Magnetic Resonance Images

Abstract

We performed PELF in elderly patients with LFS. There were considerable radiographic changes in MRI, and the patients also showed clinically relevant improvement. Thus PELF resulted in sufficient decompression of the nerve root in LFS.
