Computer Three-Dimensional Reconstruction and Pain Management for Lumbar Disc Herniation Treated by Intervertebral Foramen Endoscopy

Abstract

Objective: Lumbar disc herniation leads the numbness and pain in the waist and lower limbs. Intervertebral foramen endoscopy is a minimally invasive procedure for the treatment of disc herniation. Adequate preoperative evaluation is conducive to this percutaneous skin surgery. The purpose of this study is to improve the efficacy of intervertebral foramen endoscopy in the treatment of lumbar disc herniation by preoperative computer three-dimensional reconstruction combined with pain management. Method: Fifty patients with lumbar disc herniation who met the indications of intervertebral foramen endoscopy were randomly divided into experimental group and control group. The control group was operated according to experience based on the common axial image. The experimental group was punctured according for three-dimensional visualization model of lumbar spine. Preoperative simulated puncture catheterization and perioperative pain management was applied. The catheterization time, operation time under endoscopy, fluoroscopy times during operation, the Visual Analogue Scale (VAS) and Japanese Orthopaedic Association (JOA) scores before and 1 d, 1 m and 3 m after operation were compared between two groups. Result: The three-dimensional visualization model of lumbar spine was reconstructed based on thin-layer data. According to the results of software measurement, the skin puncture point was located and the puncture angle was obtained. Compared with the control group, the catheterization time, operation time under endoscopy, fluoroscopy times during operation in experimental group were significantly reduced. There was no statistical difference in VAS and JOA scores between two groups before operation. Compared with control group, the VAS scores in experimental group at 1 d, and 1 m after operation were decreased statistically, while the JOA scores were increased statistically. Conclusion: Three-dimensional visualization model of lumbar spine and virtual operation planning can directly judge the feasibility of intervertebral foramen endoscopy in the treatment of lumbar disc herniation, improve the efficiency of operation, and further improve postoperative efficacy with pain management.
