Anterior Spinal Instrumented Fusion & Correction

Overview

What is Anterior Spinal Instrumented Fusion & Correction?

Anterior spinal instrumented fusion and correction is a surgical procedure to treat certain types of scoliosis and spinal deformity, particularly in adolescents with curves located in the thoracic or lumbar region. The operation approaches the spine from the front (anterior), allowing the surgeon to correct the curvature, stabilise the vertebrae, and fuse the affected segments, often with a shorter fusion area than posterior surgery. This approach preserves more spinal mobility where appropriate and targets deformity at its apex.

Who is it for?

If you have a flexible, single-curve scoliosis (Lenke type 1 or 5), particularly affecting the thoracic or lumbar spine, and non-surgical treatments have not worked or the curve is progressing, you may be a candidate for anterior spinal fusion and correction.

Patients considered for this procedure typically include:

  • Adolescents with idiopathic scoliosis involving one major curve (most often in the thoracic or lumbar region)
  • Patients with curves that are flexible and meet criteria based on age, degree of curve, and flexibility
  • Individuals with progressive or severe spinal curvature at risk of worsening function or appearance
  • Those experiencing functional impairment, pulmonary issues, or significant cosmetic concerns from the deformity

What the Procedure Involves

You can expect several steps during this surgery:

  • The procedure is performed under general anaesthesia, often through a small incision on the side or front of the chest or abdomen
  • Surgeons carefully move aside muscles, blood vessels, and sometimes organs to access the spine
  • The affected disc(s) and soft tissues are removed at the apex of the curve
  • Metal rods and screws are inserted into the vertebrae to correct and stabilise the curvature
  • Bone graft material is placed to promote fusion between the vertebrae
  • The incision is closed and you are monitored in recovery
    This approach may allow a shorter segment of the spine to be fused and is chosen based on curve type and overall spinal balance.

Risks and Complications

As with any major spine surgery, there are certain risks you should be aware of, including:

  • Infection, bleeding, or the need for transfusion
  • Injury to nerves, spinal cord, or nearby organs (lungs, abdominal structures)
  • Lung complications, such as temporary decreased pulmonary function (most patients recover with time)
  • Non-fusion (pseudoarthrosis)
  • Implant loosening, breakage, or need for revision surgery
  • Pulmonary or cardiac risks during and after surgery
  • Loss of some spinal flexibility
    Complications are generally uncommon, especially in carefully selected patients, but will be discussed before surgery.

Recovery Expectations and Duration

  • After anterior spinal fusion and correction, most patients experience the following:
  • A hospital stay of 4–7 days, with pain managed and respiratory support as needed
  • Early mobilisation and gentle physiotherapy start while in hospital
  • Light activities and school attendance resume in 4–8 weeks
  • Bending and strenuous activities are limited for several months while fusion takes place
  • Most patients return to full activities within 6–12 months, once imaging confirms solid fusion and curve correction is stable
  • Pulmonary function almost always recovers within a few years after surgery, even if temporarily reduced​

 

Most patients notice a visible improvement in posture and symmetry after recovery.

FAQs

Is the correction permanent?
Yes, once fusion is complete, the corrected spinal alignment is generally stable for life.

Will I need another surgery in the future?
Most patients do not require further surgery if the fusion heals well and the implants remain stable. Routine follow-up will monitor for late issues.
