Advanced Surgical Correction for Congenital Scoliosis
Hemivertebrectomy is a specialized spinal surgery used to treat congenital scoliosis caused by a hemivertebra, an abnormally formed vertebra present at birth. The procedure removes the malformed vertebra to help straighten the spine, improve spinal balance, and reduce progression of spinal deformity.
At Midwest Spine & Brain Institute, our spine specialists provide advanced evaluation and surgical treatment for congenital scoliosis and complex spinal deformities using modern spinal correction techniques and individualized care plans.
What Is Hemivertebrectomy?
Hemivertebrectomy is a surgical procedure that removes a hemivertebra, a partially formed or wedge-shaped vertebra that can cause abnormal spinal curvature.
A hemivertebra develops during fetal spinal formation when part of a vertebra fails to develop normally. As a child grows, this abnormal vertebra can cause the spine to curve unevenly, leading to congenital scoliosis.
Removing the hemivertebra helps correct the spinal deformity and may reduce the need for larger corrective surgeries later in life.
What Does Hemivertebrectomy Treat?
Hemivertebrectomy is performed to treat congenital scoliosis caused by a hemivertebra. The surgery removes the malformed vertebra and stabilizes the spine to improve alignment and help prevent worsening spinal curvature during growth.
What Is a Hemivertebra?
A hemivertebra is a congenital spinal abnormality in which one side of a vertebra does not fully develop.
Instead of forming a normal rectangular shape, the vertebra develops as a wedge-shaped segment, causing the spine to tilt or curve abnormally.
Hemivertebra May Cause:
- Congenital scoliosis
- Kyphosis
- Spinal imbalance
- Progressive spinal deformity
- Uneven shoulders or hips
Some children may have a single hemivertebra, while others may have multiple spinal abnormalities.
Symptoms of Congenital Scoliosis
Symptoms vary depending on the severity and location of the spinal curvature.
Common Symptoms Include:
- Visible spinal curvature
- Uneven shoulders
- Uneven hips
- Rib prominence
- Leaning posture
- Back asymmetry
- Difficulty with posture
- Progressive spinal deformity during growth
Severe spinal curves may eventually affect balance, mobility, or lung development in some patients.
Causes and Risk Factors
Congenital scoliosis occurs due to abnormal spinal development before birth.
Potential Causes Include:
- Improper vertebral formation during fetal development
- Failure of spinal segmentation
- Congenital vertebral anomalies
- Rare genetic or developmental syndromes
Most cases are not caused by anything parents did during pregnancy.
How Congenital Scoliosis Is Diagnosed
Early diagnosis is important to monitor spinal growth and progression.
Diagnostic Evaluation May Include:
- Physical examination
- Standing scoliosis X-rays
- MRI of the spine
- CT scan
- Growth monitoring
- Neurological evaluation
Imaging helps determine:
- Curve severity
- Spinal balance
- Presence of hemivertebra
- Associated spinal cord abnormalities
Non-Surgical Treatment Options
Some mild congenital curves may initially be monitored without surgery.
Non-Surgical Treatments May Include:
- Observation and serial imaging
- Physical therapy
- Bracing in select cases
- Growth monitoring
However, congenital scoliosis caused by a hemivertebra often progresses as a child grows, making surgery necessary in many cases.
Hemivertebrectomy Surgical Procedure
Hemivertebrectomy removes the malformed vertebra and stabilizes the spine to improve alignment.
How Hemivertebrectomy Is Performed
1. Surgical Approach
The procedure may be performed using:
- A posterior-only approach (through the back)
- Combined anterior and posterior approaches in complex cases
Modern techniques commonly allow correction through a single-stage posterior surgery.
2. Removal of the Hemivertebra
The surgeon carefully removes the underdeveloped vertebra causing the deformity.
3. Spinal Realignment
After removal, the spine is gently corrected into improved alignment.
4. Spinal Fusion and Stabilization
Instrumentation such as rods and screws may be used to stabilize the spine while fusion occurs.
A limited fusion involving a small number of spinal levels is often preferred when surgery is performed early in childhood.
Benefits of Early Hemivertebrectomy
Early surgical treatment may help prevent worsening spinal deformity during growth.
Potential Benefits Include:
- Improved spinal alignment
- Reduced curve progression
- Better spinal balance
- Smaller fusion area
- Reduced risk of severe deformity later in life
- Improved posture
- Improved long-term spinal development
Early intervention may help avoid larger, more complex spinal fusion surgeries later.
Risks and Potential Complications
As with any spinal surgery, hemivertebrectomy carries potential risks.
Possible Risks Include:
- Infection
- Bleeding
- Nerve injury
- Spinal cord injury
- Failure of fusion
- Hardware complications
- Residual spinal deformity
- Need for future surgery
- Anesthesia-related risks
Advanced spinal monitoring and modern surgical techniques help improve safety during surgery.
Recovery After Hemivertebrectomy
Recovery varies depending on the child’s age, spinal deformity severity, and surgical complexity.
Recovery Expectations
- Hospital stay after surgery
- Pain management and activity restrictions
- Gradual return to normal activities
- Follow-up spinal imaging
- Monitoring spinal growth over time
- Physical therapy in some cases
Most children gradually return to school and routine activities as healing progresses.
Hemivertebrectomy vs Spinal Fusion Alone
| Procedure | Goal | Common Use |
| Hemivertebrectomy | Remove abnormal vertebra and correct curve | Congenital scoliosis with hemivertebra |
| Spinal Fusion Alone | Stabilize spinal curve | Some scoliosis cases without vertebral removal |
Removing the hemivertebra may allow for better deformity correction and shorter fusion levels in selected patients.
Preventing Progression of Congenital Scoliosis
Congenital scoliosis itself cannot usually be prevented because it develops before birth.
However, early diagnosis and treatment may help:
- Reduce spinal curve progression
- Preserve spinal balance
- Improve long-term spinal growth
- Lower the need for extensive future surgery
Regular follow-up with a spinal deformity specialist is important during growth.
When to See a Spine Specialist
You should seek evaluation if your child has:
- Uneven shoulders or hips
- Visible spinal curvature
- Abnormal posture
- Rib prominence
- Progressive scoliosis
- Congenital spinal abnormalities on imaging
Early evaluation allows for timely treatment planning and monitoring.
