Bone Necrosis Adjacent to the Disc After Percutaneous Laser Disc Decompression — An Analysis of Magnetic Resonance Imaging

Salvage Operation for Persistent Low Back Pain and Sciatica Induced by Percutaneous Laser Disc Decompression Performed at Outside Institution: Correlation of Magnetic Resonance Imaging and Intraoperative and Pathological Findings

“…Some recent reports describe patients treated surgically for complications of percutaneous laser disc decompression (PLDD). [17][18][19][20][21][22] We have not yet introduced this procedure into practice and have recently encountered an increasing number of patients with serious complications or unsatisfactory therapeutic outcomes of PLDD that are attributable to use of inappropriate irradiation condition or wrong selection of patients treated with this procedure. To clearly identify current problems with PLDD, we compared the clinical and magnetic resonance (MR) findings as well as the pathological features of resected herniated masses in those patients who had failed with PLDD performed elsewhere and underwent salvage operations at our hospital or any of its related institutions.…”
