Spine fusion surgery is used to durably stabilize the spine. It is often combined with instrumentation surgery, but they are not the same thing. Fusion occurs hen bone grows joining two bones into one.
Quick Facts:
- Fusion is bone growing together
- Often combined with instrumentation for rigid short term stability
- Used for complex conditions affecting multiple levels
- Designed to hold the be permenant

👉 Refer a Patient
WHAT IS THE DIFFERENCE BETWEEN INSTRUMENTATION AND FUSION?
Two different approachs to the same goal – stabilization:
Instrumentation (Structural Support)
- Placement of screws, rods, and other implants
- Provides immediate stability
Fusion (Long-Term Stability)
- Bone graft or biologic material is used
- Allows vertebrae to heal together into a single solid structure
👉 The goal is to create a stable, well-aligned spine that can support normal function
WHY IS THIS SURGERY PERFORMED?
This type of surgery is used when the spine requires significant structural support or correction.
Common Indications
- Spinal instability
- Spondylolisthesis
- Spinal deformity (scoliosis, kyphosis)
- Fractures
- Tumors affecting the spine
- Infection
- Revision surgery (failed prior procedures)
👉 It is often used for multilevel or complex spinal conditions
SYMPTOMS THAT MAY REQUIRE THIS SURGERY
Common Symptoms
- Severe back pain
- Progressive deformity
- Difficulty standing or walking
- Loss of balance
Neurologic Symptoms
- Leg pain
- Numbness or tingling
- Weakness
🚨 When Surgery May Be More Urgent
- Progressive neurologic deficit
- Spinal instability after fracture or tumor
- Inability to stand or walk
HOW IS THE PROCEDURE PERFORMED?
Step-by-Step Overview
- Anesthesia
- Performed under general anesthesia
- Surgical Approach
- Typically through the back (posterior approach)
- May be combined with anterior or lateral approaches
- Decompression (If needed)
- Nerves or spinal cord are decompressed
- Instrumentation Placement (If needed)
- Screws are placed into vertebrae and/or pelvis
- Rods connect the screws to stabilize the spine
- Fusion
- Bone graft is placed to promote healing across levels
👉 The procedure is tailored to the extent of disease and alignment goals
OUR APPROACH
We focus on thoughtful planning and precise execution.
- We evaluate alignment, stability, and overall spinal balance
- We aim to treat the necessary levels while avoiding unnecessary extension
- Bone quality and patient health are key considerations
- The goal is durable correction and long-term function
👉 These procedures require individualized planning and careful decision-making
WHAT TO EXPECT
Before Surgery
- MRI, CT, and standing X-rays
- Assessment of alignment and stability
- Preoperative planning and optimization
Day of Surgery
- Performed under general anesthesia
- Procedure length depends on number of levels
After Surgery
- Hospital stay is common
- Gradual recovery over weeks to months
- Focus on mobility and function
- Fusion develops over time
OUTCOMES & RISKS
Potential Benefits
- Improved spinal stability
- Correction of deformity
- Relief of nerve compression
- Improved posture and function
- Reduced pain
Risks
- Infection
- Bleeding
- Nerve injury
- Hardware complications
- Failure to fuse (pseudarthrosis)
- Adjacent segment stress
👉 Outcomes depend on appropriate patient selection and successful healing
FREQUENTLY ASKED QUESTIONS
Is this a major surgery?
Yes, these are often complex procedures, but they are carefully planned.
Will I lose motion in my spine?
Motion is reduced at fused levels, but overall function is often improved.
How long does recovery take?
Recovery is gradual and depends on the extent of surgery.
Why is pelvic fixation sometimes needed?
It provides additional support for long constructs or unstable lower segments.
