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

Background And Study Aims/objective:  Clinical outcomes of percutaneous endoscopic lumbar foraminoplasty (PELF) performed for lumbar foraminal stenosis (LFS) have been reported in the literature. However, no study has reported the radiographic changes in magnetic resonance imaging (MRI) after surgery. This report presents the clinical outcome as well as radiographic changes in MRI after PELF for elderly patients with unilateral radiculopathy.
