🔬 Open Microdiscectomy

Indication: Herniated disc with severe nerve compression, calcified herniations, or herniations with multiple fragments.

Procedure: Through a 3-5 cm incision, I use microscopic magnification to directly visualize the compressed nerve root, remove the herniated disc, and completely decompress the affected nerve.

• Advantage over endoscopic surgery: Allows management of complex herniations with multiple fragments or extensive calcification
• Duration: 60-90 minutes under general anesthesia
• Hospital stay: Typically 1-2 days
• Success rate: 85-95% complete relief of sciatica

🏗️ Decompressive Laminectomy

Indication: Multilevel spinal stenosis, spinal cord compression due to tumors, urgent cauda equina decompression.

Procedure: Complete removal of vertebral laminae (the roof of the spinal canal) to create ample space for the compressed spinal cord or nerve roots.

• Multilevel laminectomy: Allows decompression of 3-5 levels simultaneously
• Cervical laminoplasty: A bone-preserving technique for cervical stenosis
• With or without fusion: Depending on residual stability after decompression
• Functional recovery: Progressive neurological improvement over 3-6 months

🔩 Spinal Fusion (PLIF, TLIF, ALIF, ACDF)

Indication: Vertebral instability, spondylolisthesis, multilevel degenerative disease, deformity requiring correction.

Techniques by approach:

• PLIF (Posterior Lumbar Interbody Fusion): Posterior approach with bilateral placement of cages between vertebral bodies
• TLIF (Transforaminal Lumbar Interbody Fusion): Unilateral posterior approach that preserves more musculature
• ALIF (Anterior Lumbar Interbody Fusion): Anterior approach that completely avoids the posterior musculature
• ACDF (Anterior Cervical Discectomy and Fusion): Gold standard for multilevel cervical disc disease

Components of fusion:

• Complete neural decompression
• Preparation of bony surfaces for fusion
• Placement of interbody cages (PEEK or titanium)
• Instrumentation with pedicle screws and rods (lumbar) or a plate (cervical)
• Bone graft (autograft or substitute) to promote solid fusion

Solid fusion rate: 90-95% at 12 months with proper technique

📐 Deformity Correction (Osteotomies)

Indication: Severe scoliosis, fixed kyphosis, post-traumatic deformity, flatback syndrome.

Types of osteotomies:

• Smith-Petersen osteotomy (SPO): Resection of posterior elements for angular correction of ~10 degrees per level
• Pedicle subtraction osteotomy (PSO): Wedge resection of the vertebral body for correction of 30-40 degrees
• Vertebral column resection (VCR): Complete removal of a vertebra for maximum correction in rigid deformities

Critical monitoring: Use of motor and somatosensory evoked potentials in real time to protect the spinal cord during manipulation of the spine.

Hospital stay: Typically 5-7 days with multimodal pain management

Outcome: Restoration of sagittal balance and alignment that dramatically improves quality of life and prevents progression

🎯 Spinal Tumor Resection

Indication: Intramedullary tumors (astrocytomas, ependymomas), extramedullary tumors (meningiomas, schwannomas), primary vertebral tumors.

My expertise in intramedullary tumors:

• Precise longitudinal myelotomy: Opening the spinal cord along the posterior midline while preserving neural tracts
• Microsurgical resection under magnification: Tumor-cord dissection with neural preservation techniques
• Advanced neurophysiological monitoring: Continuous evoked potentials and EMG for functional mapping
• Watertight dural closure: Prevention of CSF fistulas

Extramedullary tumors: En bloc resection of meningiomas and schwannomas with preservation of neurological function

Vertebral tumors: Vertebrectomy with reconstruction using expandable cages and multilevel fixation

Goal: Maximum safe resection with preservation or improvement of neurological function

🔄 Spine Revision Surgery

Indication: Pseudarthrosis (failed fusion), failed instrumentation, infection, adjacent segment syndrome, suboptimal results from prior surgery.

Unique challenges of revision surgery:

• Distorted anatomy: Extensive scarring from prior surgery(ies)
• Identification of structures: Careful navigation in an altered surgical field
• Hardware removal: Extraction of previously placed screws, rods, or cages
• Revised strategy: Analysis of why the prior surgery failed and correction of the underlying problem

My approach to revisions: A thorough study of the prior surgery(ies), updated imaging, biomechanical analysis of the causes of failure, and a surgical plan specific to your unique situation.

Success rate: 70-85% improvement with appropriately planned revision surgery (lower than primary surgery but significant)

🏥 Hospital Logistics and Planning

• Planned hospital stay: Typically 3-7 days (depending on the complexity of the procedure)
• Intensive Care Unit: May be required for 24-48 hours after surgery in complex cases
• Autologous blood: Donation of your own blood 2-3 weeks before for transfusion if needed
• Home preparation: Adaptations for initial postoperative limitations
• Support network: Identify a family member/friend to support you during the first 2-4 weeks

1️⃣ Anesthesia and Positioning

After your arrival in the operating room:

• General anesthesia: You will be completely asleep, without pain or awareness during the procedure
• Complete monitoring: Electrocardiogram, blood pressure, oxygen saturation
• Specialized positioning: Prone (face down) for posterior spine, or supine/lateral depending on the approach
• Protection of pressure points: Careful padding to prevent injuries from prolonged positioning

2️⃣ Marking and Field Preparation

• Localization with fluoroscopy: Intraoperative X-rays to mark exactly which levels to operate on
• Sterile preparation: Extensive surgical cleaning of the skin
• Placement of sterile drapes: Only the surgical area is exposed
• Neuronavigation (when applicable): A computer-guided system for precise placement of implants

3️⃣ Approach and Incision

• Midline incision: Over the spinous processes for a posterior approach
• Length according to extent: 6-20 cm depending on the levels to be instrumented
• Subperiosteal dissection: Separation of muscles from the vertebrae while preserving blood supply
• Meticulous hemostasis: Bleeding control with electrocautery and hemostatic agents
• Placement of retractors: Spreaders that keep the surgical field open

4️⃣ Neural Decompression

This is the critical phase of releasing compressed nerve structures:

• Laminectomy: Removal of vertebral laminae with a high-speed drill
• Foraminotomy: Enlargement of the neural foramina where nerve roots exit
• Partial facetectomy: Removal of hypertrophied facet joints
• Discectomy: Removal of the herniated disc under microscopic visualization
• Verification of decompression: I confirm that the spinal cord/nerve roots have adequate space

5️⃣ Instrumentation and Fusion (If Applicable)

• Pedicle preparation: Creation of trajectories for pedicle screws
• Screw placement: With fluoroscopic guidance or navigation, I place screws in each vertebra to be fused
• Preparation of bony surfaces: Decortication (scraping) of bone to stimulate fusion
• Placement of interbody cages: PEEK or titanium spacers between vertebral bodies
• Bone graft: Local bone autograft or graft substitute around the implants
• Connection with rods: Titanium rods connect the screws, creating a rigid construct
• Compression/distraction: Adjustments for alignment and restoration of disc height

6️⃣ Verification and Closure

• Final fluoroscopy: X-rays confirm the correct position of all implants
• Final hemostasis: Verification that there is no active bleeding
• Copious irrigation: Irrigation of the surgical field with diluted antibiotic
• Placement of drains: Tubes that remove blood/fluid during the first 24-48 hours
• Layered closure: Suturing of fascia, subcutaneous tissue, and skin in separate layers
• Sterile dressing: A protective dressing over the incision

🏥 Hospital Stay (Days 0-5)

• Long-term follow-up: Annual evaluation to monitor adjacent segments

⚠️ General Surgical Risks (Apply to Any Major Surgery)

• Infection (2-5%): Superficial (skin) or deep (disc/vertebral space). Managed with prolonged IV antibiotics; rarely requires repeat surgery for washout.
• Bleeding (1-3%): Excessive blood loss requiring transfusion. In rare cases, postoperative bleeding requiring re-exploration.
• Deep vein thrombosis (1-2%): Clots in the legs. Prevention with compression stockings, early mobilization, prophylactic anticoagulation.
• Pulmonary embolism (<1%): A clot travels to the lungs. A serious but rare complication with appropriate prophylaxis.
• Cardiopulmonary complications (1-3%): Higher risk in patients >65 years or with comorbidities. Preoperative evaluation identifies high-risk patients.

🧠 Risks Specific to Spine Surgery

• Nerve root injury (1-3%): Damage to a nerve during surgical manipulation. May result in persistent weakness or sensory alteration.
• Spinal cord injury (<1%): A devastating but extremely rare complication. Higher risk in cervical or thoracic surgeries.
• CSF fistula (1-5%): Leakage of cerebrospinal fluid due to a dural tear. Most are managed with rest; some require re-suturing.
• Pseudarthrosis (5-15%): Failure of bony fusion. Risk factors: smoking, diabetes, multilevel surgery, obesity. May require repeat surgery.
• Implant malposition (1-2%): Screws or cages outside the ideal position. Use of neuronavigation reduces this risk.
• Adjacent segment syndrome (10-20% at 10 years): Accelerated degeneration of levels above/below the fusion. A natural phenomenon that may require additional surgery.

🎯 Risks Specific to Complex Procedures

Deformity correction with osteotomies:

• Neurological injury (2-5%) - Higher than standard surgery due to spinal manipulation
• Significant blood loss (average 1-2 liters) - Transfusion frequently necessary
• Major medical complications (5-10%) - Due to the prolonged duration of surgery

Intramedullary tumor resection:

• New/worsened neurological deficit (10-30%) - Inherent risk of intramedullary surgery
• Dependent on the size and location of the tumor
• Neurophysiological monitoring reduces but does not eliminate this risk

Revision surgeries:

• Complications 2-3x higher than primary surgery
• Scar tissue increases technical difficulty
• Less predictable clinical outcomes
