Spinal Fusion Surgery

Spinal fusion surgery stabilizes the spine, corrects scoliosis and spinal deformity, and relieves nerve compression when conservative care is no longer sufficient. PPO Insurance Accepted.

Spinal Fusion for Scoliosis, Instability & Chronic Back Pain

Spinal fusion surgery stabilizes two or more vertebrae so they heal into one solid segment. It may be considered when pain or nerve symptoms are driven by confirmed instability, deformity, spondylolisthesis, recurrent stenosis with instability risk, pseudarthrosis, traumatic instability, or selected cases of severe degenerative disc disease.

Fusion is not the right answer for every back or neck pain complaint. The decision depends on whether imaging, standing alignment, neurologic findings, and symptoms all point to a structural problem that fusion can reasonably address. Mountain Spine & Orthopedics performs fusion across cervical, thoracic, and lumbar levels, including lumbar fusion surgery, with minimally invasive approaches considered when anatomy and goals support them.

For selected L5-S1 pathology, the fusion discussion may include specialized access options such as Axial Lumbar Interbody Fusion (AxiaLIF), a presacral approach that reaches the L5-S1 disc space through a small incision near the tailbone. This technique is not a general substitute for lumbar fusion; it is considered only when the anatomy, diagnosis, and surgical goals fit a targeted lumbosacral fusion. PPO Insurance Accepted.

When is Spinal Fusion Recommended?

  • Adult scoliosis with curves exceeding 40–50 degrees or producing neurological symptoms
  • Degenerative disc disease or spondylolisthesis causing spinal instability and chronic back or leg pain
  • Spinal stenosis producing severe neurogenic claudication unresponsive to injections and conservative care
  • Prior spine surgery with adjacent segment disease or pseudarthrosis (failed fusion requiring revision)
  • Selected L5-S1 degenerative disc disease, collapsed disc space, or low-grade spondylolisthesis where a targeted lumbosacral fusion approach is anatomically appropriate
  • Spinal deformity including kyphosis or sagittal imbalance requiring surgical correction
  • Severe spinal fractures, trauma, or spinal instability from infection or tumor

Surgical Approach Options for Spinal Fusion

  1. Decompression: Bone spurs, disc material, or ligament pressing on nerves is removed to relieve pain before fusion
  2. TLIF (Transforaminal Lumbar Interbody Fusion): Posterior approach with excellent access for decompression and single or multilevel fusion — the workhorse of scoliosis and degenerative disc surgery
  3. ALIF (Anterior Lumbar Interbody Fusion): Anterior approach allowing large cage placement to restore lordosis — particularly valuable in scoliosis correction and sagittal balance restoration
  4. OLIF or XLIF: Lateral approaches used in minimally invasive multilevel scoliosis correction, avoiding posterior muscle disruption
  5. AxiaLIF / axial lumbar interbody fusion: A specialized presacral L5-S1 approach that may restore disc height and place graft or instrumentation while avoiding posterior muscle disruption in carefully selected patients
  6. Posterior instrumentation: Pedicle screw and rod fixation, often combined with interbody fusion in multilevel scoliosis surgery for maximum correction and stability
  7. Bone grafting: Autograft, allograft, or synthetic graft is placed to stimulate solid bone fusion over 6–12 months

Benefits of Spinal Fusion Surgery

  • Corrects and stabilizes adult scoliosis and spinal deformity
  • Permanently eliminates painful motion at unstable or severely degenerated segments
  • Relieves nerve compression causing leg pain, numbness, and weakness
  • Restores disc height and sagittal balance for improved posture and function
  • May be performed with minimally invasive approaches when anatomy and goals are appropriate
  • PPO Insurance Accepted — our team handles pre-authorization and coverage verification

Recovery After Spinal Fusion

Recovery Timeline: 6-12 Months for Full Fusion Maturation

Recovery after spinal fusion depends on the level treated, number of levels, whether decompression or deformity correction was performed, bone quality, smoking status, and overall health. Walking usually begins early under clinical guidance, while bending, lifting, twisting, work demands, and driving are restricted according to the surgeon's protocol. Fusion maturation is monitored over months with follow-up imaging. Nicotine avoidance is important because nicotine impairs bone healing and increases pseudarthrosis risk.

Frequently Asked Questions

What are the permanent restrictions after spinal fusion?

For a single-level fusion, there are few permanent restrictions. For multi-level fusions, doctors typically advise avoiding heavy deadlifts, high-impact contact sports, and extreme spinal twisting to prevent adjacent segment disease.

How serious is spinal fusion surgery?

Spinal fusion is a major orthopedic procedure. While safe and common, it involves a recovery period of several months. It is reserved for cases where instability, deformity, or severe nerve compression cannot be treated non-surgically.

Does spinal fusion stop you from bending?

A single-level fusion limits motion only at that specific segment, which is barely noticeable. Even with multi-level fusions, patients can still bend at the hips (hip-hinge) to pick things up, maintaining good functional mobility.

What is the 'dark side' of spinal fusion?

The 'dark side' refers to Adjacent Segment Disease, where the discs above and below the fusion wear out faster due to increased stress. This can occur years later, potentially requiring additional surgery. Minimally invasive techniques aim to reduce this risk.

What is AxiaLIF or axial lumbar interbody fusion?

AxiaLIF is a specialized L5-S1 fusion approach that reaches the disc space through a small presacral corridor near the tailbone. It is considered only for selected lumbosacral anatomy and is part of the broader spinal fusion decision.
