Vertebral Body Tethering May Not Improve Cobb Angle

New research questions the effectiveness of vertebral body tethering (VBT) in improving Cobb angles for scoliosis patients. While VBT is seen as an alternative to spinal fusion, studies reveal inconsistent results. Non-invasive treatments like the ScolioLife® Method and ScolioAlign® Brace offer safer, proven solutions for scoliosis management.

Introduction

New research presented at the International Congress on Early Onset Scoliosis and the Growing Spine questions the effectiveness of vertebral body tethering (VBT) in improving the major Cobb angle for adolescent idiopathic scoliosis patients. While VBT is seen as a promising alternative to spinal fusion surgery, the study highlights significant limitations and emphasizes the need for further investigation.

Study Findings on Vertebral Body Tethering

The study analysed 113 patients who underwent vertebral body tethering between 2013 and 2020, revealing the following outcomes:
 

• Preoperative Cobb Angle: Mean of 51.1°.
• First Post-Operative Radiographs: Mean improvement to 27.4°.
• Final Follow-Up: Mean Cobb angle of 31.1°.

Stability and Curve Changes

• Stable Curves: Observed in 50.4% of patients.
• Cobb Angle Increase: Over 5° increase seen in 41.6% of patients.
• Improvement: Only 8% of patients showed a decrease greater than 5°.
• Significant Correction: Achieved by 4.4% of patients with more than 10° correction.

According to Dr. Lindsay M. Andras, associate division chief at the Jackie and Gene Autry Orthopaedic Centre, these results indicate that VBT may not consistently harness growth effectively. The study also suggests that younger patients and more aggressive correction during surgery may yield better results.

The Need for Further Research

While VBT has been promoted as a less invasive alternative to spinal fusion, its long-term benefits and risks remain uncertain. Areas requiring more research include:
 

• Patient Selection: Identifying the ideal candidates for VBT.
• Optimal Timing: Determining the best age and growth stage for the procedure.
• Durability of Corrections: Understanding the long-term stability of outcomes.

Safer Alternatives: Non-Invasive Scoliosis Treatments

Given the limitations and risks associated with surgical procedures like VBT, non-invasive scoliosis treatments are a safer and effective first-line approach. The ScolioLife® Method and ScolioAlign® Brace provide holistic, non-surgical options for scoliosis management.

The ScolioLife® Method

Developed by Dr. Kevin Lau, this method integrates:
 

• Specialized Exercises: Strengthen spinal muscles and improve alignment.
• Manual Therapy: Reduces pain and enhances mobility.
• Nutritional Counselling: Supports overall spinal health and healing.

The ScolioAlign® Brace

A custom-made brace using 3D scanning and printing technology, the ScolioAlign® Brace:
 

• Gradually corrects spinal curvature over time.
• Ensures a perfect fit tailored to the patient.
• Provides effective, non-invasive correction with minimal discomfort.

Benefits of Non-Surgical Approaches

Both the ScolioLife® Method and the ScolioAlign® Brace offer significant advantages:
 

• Non-Invasive Treatment: Avoids surgical risks and long recovery times.
• Customizable Care: Tailored to individual needs for optimal results.
• Minimal Side Effects: Ensures a safe and effective treatment experience.

Conclusion

While vertebral body tethering may offer an alternative to spinal fusion surgery, current research highlights its limitations and need for further validation. Non-invasive options like the ScolioLife® Method and ScolioAlign® Brace present effective and safer solutions for managing scoliosis without the risks associated with surgery. Patients are encouraged to explore these alternatives and consult healthcare professionals to determine the best treatment approach for their condition.
