🧠🦴 SPINE SURGERIES – OVERVIEW Spine surgeries are performed to treat a wide range of spinal conditions including degenerative diseases, trauma, deformities, tumors, and infections affecting the cervical, thoracic, or lumbar spine. 🔹 Common Indications for Spine Surgery Condition Examples Degenerative Disc herniation, spinal stenosis, spondylolisthesis Trauma Vertebral fractures, dislocations Deformity Scoliosis, kyphosis Infection Tuberculosis (Pott's spine), discitis Tumors Primary or metastatic spinal tumors Instability Due to degeneration, trauma, or surgery 🔹 Goals of Spine Surgery Relieve nerve compression (e.g. sciatica, radiculopathy) Stabilize the spine (internal fixation, fusion) Correct deformities Remove pathological tissue (e.g. tumor, abscess) Restore spinal alignment and function 🔹 Types of Spine Surgeries 1. Discectomy / Microdiscectomy Indication: Herniated disc compressing nerve root (sciatica, radiculopathy) Microdiscectomy: Minimally invasive, less muscle damage Most common in: Lumbar spine 2. Laminectomy / Laminotomy Laminectomy: Removes lamina to decompress spinal canal (for spinal stenosis) Laminotomy: Partial removal (more conservative) Common in lumbar and cervical stenosis 3. Spinal Fusion Indication: Instability (e.g., spondylolisthesis, fractures, severe degeneration) Joins two or more vertebrae using bone grafts + hardware (screws/rods/plates) Can be: PLIF (Posterior Lumbar Interbody Fusion) TLIF (Transforaminal Lumbar Interbody Fusion) ALIF (Anterior Lumbar Interbody Fusion) ACDF (Anterior Cervical Discectomy and Fusion) 4. Vertebroplasty / Kyphoplasty Indication: Osteoporotic vertebral compression fractures Vertebroplasty: Injection of bone cement into vertebral body Kyphoplasty: Balloon inflation before cement injection to restore height 5. Deformity Correction For scoliosis or kyphosis Involves long-segment instrumentation and fusion May use pedicle screws, rods, osteotomies 6. Spinal Tumor Surgery Decompression ± excision of tumor May involve spinal stabilization or reconstruction Requires multidisciplinary planning (oncology, radiology) 7. Endoscopic Spine Surgery (MISS) Minimally invasive alternative for discectomy, decompression Uses tubular retractors and cameras Reduced pain and quicker recovery 🔹 Spinal Levels & Surgeries Region Common Surgeries Cervical ACDF, cervical laminectomy, posterior fixation Thoracic Discectomy, corpectomy (e.g. for TB/tumor), deformity correction Lumbar Discectomy, TLIF, laminectomy, vertebroplasty 🔹 Risks and Complications Infection Nerve injury Dural tear → CSF leak Implant failure Adjacent segment degeneration Nonunion (in fusion cases) Persistent pain (Failed Back Surgery Syndrome) 🔹 Rehabilitation & Recovery Early mobilization (especially after MISS) Bracing if needed Physiotherapy: core strengthening, posture correction Gradual return to activity 🔹 Advances in Spine Surgery ✅ Minimally Invasive Spine Surgery (MISS) ✅ Robotic-assisted spine surgery ✅ Intraoperative navigation & neuromonitoring ✅ Biologics for fusion (e.g. BMPs) ✅ Artificial disc replacement (motion-preserving alternative) 🔹 Summary Chart Surgery Indication Approach Invasiveness Discectomy Herniated disc Posterior Conventional or minimally invasive Laminectomy Spinal stenosis Posterior Open or minimal Fusion (e.g. TLIF) Instability, degeneration Anterior/Posterior Moderate–high Vertebroplasty Compression fracture Percutaneous Minimally invasive Tumor excision Spinal tumors Any Variable
