Scoliosis is a spinal condition characterized by an abnormal sideways curvature that can affect posture, comfort, and daily activities. While some cases can be managed through observation or other conservative treatments, certain patients may benefit from specialized surgical procedures. Scoliosis tethering surgery is one option that may help eligible patients correct spinal curvature while preserving more natural spinal movement.
Scoliosis tethering surgery, also known as vertebral body tethering (VBT), is a growth-modulation procedure primarily used for selected children and adolescents who are still growing. Unlike traditional spinal fusion, which permanently joins certain vertebrae, tethering uses a flexible cord attached to the vertebrae with screws. The tension on the cord helps guide spinal growth and gradually improve the curvature.
The procedure is generally considered for patients with specific types and degrees of scoliosis. A specialist evaluates factors such as spinal flexibility, curve severity, skeletal maturity, and overall health before determining whether this approach is appropriate.
Spinal tethering surgery is designed to influence spinal growth while allowing movement between the treated vertebrae. During the procedure, a surgeon typically accesses the spine through small incisions in the chest or side of the body, depending on the surgical approach and the patient's anatomy.
The surgeon places screws into selected vertebrae and connects them with a flexible cord. As the patient continues to grow, the tether can help guide the spine toward improved alignment.
Potential advantages may include:
Preserving more spinal flexibility than fusion.
Supporting gradual correction as the patient grows.
Offering an alternative to fusion for appropriately selected patients.
Allowing a different approach to managing certain progressive spinal curves.
However, results vary, and tethering is not suitable for every patient. Possible complications include tether breakage, inadequate correction, overcorrection, and the need for additional surgery.
Patient selection is essential for successful treatment. Scoliosis tethering surgery is generally considered for growing patients with progressive scoliosis who meet specific clinical criteria. It is not typically the standard option for adults whose spinal growth is complete.
A comprehensive evaluation may involve physical examinations, standing spinal X-rays, assessment of skeletal maturity, and a review of symptoms and medical history. These findings help determine whether tethering, spinal fusion, observation, or another treatment is most appropriate.
John Asghar MD emphasizes the importance of understanding each patient's spinal condition before choosing a treatment plan. Discussing available surgical and nonsurgical options with a qualified spine specialist can help patients and families make informed decisions.
Patients considering spinal tethering surgery should ask about expected correction, recovery time, potential complications, long-term monitoring, and the possibility of further procedures. Understanding these factors helps establish realistic expectations and supports informed treatment decisions.
Scoliosis tethering surgery offers a growth-preserving approach for selected children and adolescents with progressive spinal curvature. By using a flexible cord to guide spinal growth, the procedure may improve alignment while preserving more movement than traditional fusion. However, suitability depends on individual clinical factors, and careful evaluation is essential. John Asghar MD encourages patients and families to seek specialized spine guidance to understand their options and determine an appropriate treatment strategy.
