Percutaneous Endoscopic Diskectomy using an Interlaminar Approach Based on 3D CT/MR Fusion Imaging.

摘要: Background With effective preoperative planning, percutaneous endoscopic diskectomy (PED) via an interlaminar approach (PED-IL) can reduce the need for partial laminectomy. Our aim was to assess clinical outcomes of PED-IL, planned using three-dimensional fusion computed tomography and magnetic resonance (3D CT/MR) images. Material Methods Our retrospective analysis based on data from 102 patients (66 were men) treated by PED-IL. Preoperative planning positional relationship between nerve root lumbar disk herniation, visualized 3D CT/MR images through a simulated IL window.
