Surgically Relevant Morphological Parameters of the L5-S1 Interlaminar Window: A Statistical Analysis Based on 3D Reconstruction of CT Data.

The morphological measurement of the L5-S1 interlaminar window based on 3D reconstruction provided accurate and reliable reference data for epidural puncture approach and posterior approach of lumbar surgery. Moreover, it could also assist the placement of endoscopic working channel in percutaneous endoscopic interlaminar discectomy (PEID) and might be useful for further studies of anatomical and surgical consideration of unilateral biportal endoscopic spinal surgery (UBE) procedures. Key words: Interlaminar window; percutaneous endoscopic interlaminar discectomy (PEID); unilateral biportal endoscopy spinal surgery (UBE); 3D reconstruction.
