Core Techniques of Minimally Invasive Spine Surgery

Description

This book issues all aspects of minimally invasive spine surgery. From interventional techniques such as nerve block to multilevel fusion surgery, the field of minimally invasive surgery is organized by chapter from basics to the end. Each chapter will include various figures and tables, and videos will be added in the surgery-related parts. A special focus will be placed on spinal endoscopic surgery, which has undergone rapid development in recent years. Both full-endoscopic spine surgery and uni-portal bilateral endoscopic will be dealt. Various surgical approaches and procedures will be presented for disc-herniated disease and stenotic legion from cervical to lumbar. The new technology solution such as navigation-guided spine surgery and robot surgery and artificial and augmented reality will be introduced.     Preface Preface Preface Contents Part I: Introduction History of Minimally Invasive Spine Surgery 1 Introduction 2 The Beginning of MISS 3 Endoscopic Spine Surgery (ESS) 4 MIS Decompression and Fusion 5 Intradiscal Therapy 6 Other Percutaneous Treatment 7 Summary References Basic Concepts and Nomenclature of Minimal Invasive Spine Surgery 1 Introduction 2 Main Text 3 Summary References Learning Curve and Complications of Minimally Invasive Spine Surgery 1 Introduction 2 The Basic Concept of the Minimally Invasive Spine Surgery 3 Learning Curve of Minimally Invasive Spine Surgery 3.1 What Is the Learning Curve? 3.2 Cut-Off Point of the Learning Curve 3.3 Outcome Measures: Task-Efficiency Measures vs. Patient Outcome Measures 3.4 Current Learning Curve Studies of Minimally Invasive Spine Surgery 4 Typical Complications Related to Minimally Invasive Spine Surgery 4.1 How to Speed Up the Learning Curve and Prevent Complications 5 Summary References Part II: Endoscopic Spine Surgery History and Basic Concepts of Full-Endoscopic Spine Surgery 1 Introduction 2 History of Full-Endoscopic Spine Surgery 2.1 Foundation of Endoscopic Spine Surgery 2.2 First Generation of Endoscopic Spine Surgery 2.3 Second Generation of Endoscopic Spine Surgery 2.4 Third Generation of Endoscopic Spine Surgery 2.5 Fourth Generation of Endoscopic Spine Surgery 3 Basic Concepts of Full-Endoscopic Spine Surgery 4 Summary References Transforaminal Endoscopic Lumbar Discectomy 1 Introduction 1.1 Basic Principle 1.2 Nomenclature 1.3 Evidence 1.4 Barriers to Entry to the Endoscopic Spine Surgery 1.5 Overcoming the Learning Curve 2 Indications 3 Step-by-Step Technique 4 Technical Keys to Success 5 Perioperative Considerations 6 Dural Risk and Incomplete Decompression 7 Transforaminal Endoscopic Discectomy for Different Situations 7.1 Migrated Disc Herniation 7.2 Recurrent Disc Herniation 7.3 Foraminal/Extraforaminal Disc Herniation 7.4 Upper Lumbar Level Disc Herniation 7.5 Disc Herniation at the L5–S1 Level 8 Summary References Interlaminar Endoscopic Lumbar Discectomy 1 Introduction 2 Indications 3 Applied Anatomy 3.1 Interlaminar Window 3.2 Ligamentum Flavum 3.3 Intervertebral Foramen Size 3.4 Intervertebral Foramen Nerve Root Exit 3.5 Herniated Disc Position 4 Step-by-Step Technique 4.1 Preoperative Planning 4.2 Anesthesia 4.3 Positioning and Setting 4.4 Discography 4.5 Target Point and Needle Insertion 4.6 Epidurogram 4.7 Working Channel Establishment 4.8 Ligamentum Flavum Approach 4.9 Disc Herniation Access 4.10 Annulus Approach 5 Complications 5.1 Dural Tear 5.2 Early Relapse 5.3 Nerve Injury 5.4 Vascular Injury 5.5 Infection 6 Summary References Full Endoscopic Decompression in Thoracolumbar Stenosis 1 Introduction 2 Indications 3 Contraindications 4 Surgical Technique 4.1 Preoperative Planning 4.1.1 Plain Radiograph 4.1.2 Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) Scan 4.2 Anesthesia and Position 4.3 Special Surgical Instruments (Fig. 1) 4.4 Surgical Steps 4.4.1 Skin Incision 4.4.2 Working Cannula Docking and Insertion of Endoscope 4.4.3 Anatomical Points 4.4.4 Bony Decompression 4.4.5 Removal of the Ligament Flavum and Confirmation of the Decompressed Neural Structures 4.5 Postoperative Care 4.6 Consideration for Thoracic Decompression 5 Complications 5.1 Incomplete Decompression and Excessive Facet Violation 5.2 Intraoperative Bleeding 5.3 Incidental Durotomy 5.4 Injury to Neural Structures/Transient Dysesthesia 6 Illustrative Cases 6.1 Case 1.
