Surgical Treatment of Scoliosis

Surgical Treatment of Scoliosis

Pax Medicus connects patients with experienced spinal surgeons. Our partner centres use modern techniques to correct spinal curvature, relieve nerve compression, and restore balanced posture with safer, more predictable recovery. Diagnostic tests can also be performed preventively to provide peace of mind, even when no symptoms are present.

What is scoliosis?

Scoliosis is a three-dimensional curvature of the spine that alters alignment in all planes. The spine curves sideways (frontal plane), twists (transverse plane), and often flattens (sagittal plane). Scoliosis is diagnosed when imaging (e.g., X-ray) shows a curvature > 10° in the frontal plane. It most often affects the thoracic or thoracolumbar region; isolated lumbar scoliosis is rarer. Beyond spinal deformity, scoliosis may affect the pelvis, chest, and lower limbs and can change the position of internal organs (heart, lungs, digestive tract), leading to functional problems.

Grading by curvature size

  • Grade I (10–24°): muscular/ligament changes without bone deformity. Management: exercises or observation.
  • Grade II (25–45°): structural vertebral/disc changes with rotation and rib hump. Management: corrective exercises + specialised brace.
  • Grade III (≥50°): advanced structural deformity (e.g., vertebral wedging) typically requiring surgery.

Scoliosis – who is affected?

Children are most at risk; the condition can appear at different growth stages:

  • Infantile scoliosis (infant type): develops between 6 months and 3 years of age, typically presenting as a left-sided curvature.
  • Juvenile scoliosis (child type): occurs between 3 and 10 years of age.
  • Adolescent scoliosis (teen type): develops during puberty, and is the most common form.

In most children, the first signs of spinal deformity appear between the ages of 5 and 8 or during adolescence.

In adults, scoliosis is usually a result of spinal ageing and degeneration of the intervertebral joints. Adult scoliosis generally produces curvatures up to 20–30 degrees. Treatment is mainly based on targeted exercises and physiotherapy, while surgical intervention is reserved for patients with severe pain, neurological symptoms, or significant mobility restrictions.

What are the Categories of scoliosis?

  • Functional scoliosis: no permanent structural change; often lumbar; may relate to leg length discrepancy or hip contracture.
  • Structural (congenital) scoliosis: due to abnormal vertebral development (wedge/hemivertebrae, fused vertebrae or ribs), affecting cervicothoracic, thoracic, thoracolumbar, or lumbar regions.

What are the symptoms of scoliosis?

Typical signs include visible spinal asymmetry and changes in body alignment:

  • Uneven shoulders or hips; tilted trunk; asymmetric waist
  • Prominent shoulder blade or rib hump
  • Apparent leg-length discrepancy; balance/centre-of-gravity shift
  • In girls, retraction of one breast making it appear smaller
  • Advanced cases: back pain radiating to leg/foot, gait disturbance (limping, burning, numbness), reduced leg strength or partial paresis

How is scoliosis diagnosed?

Diagnosis is made by an orthopaedic specialist using:

  • Physical examination: shoulder/pelvic alignment, trunk symmetry, spinal shape and mobility, rib hump check, limb strength and reflexes.
  • X-ray imaging: essential to determine curve size, level, and pattern.

What does surgical treatment of scoliosis involve?

Surgery is considered for curvatures >50° that cause pain, neurological deficits, marked postural deterioration (waist/shoulder blade asymmetry, rib hump progression), gait problems or neurogenic claudication, and cardiorespiratory compromise. The goals are to halt progression, correct curvature, decompress neural elements, restore trunk balance, and stabilise the spine using titanium implants.

Posterior spinal fusion

Most common method for patients in or past puberty with single or double curves. Performed from the back; screws and rods correct the deformity in three planes.

Anterior spinal fusion

Used for selected single short-curve scoliosis. Incision along the lateral chest/abdomen; a rod fixed with screws inserted into vertebral bodies achieves correction.

Recovery and next steps

Detailed recovery plans vary by curve type and procedure. Your specialist team will advise on mobilisation, bracing (if needed), physiotherapy, and the expected timeline for returning to study, work, and sport.
