Thoracolumbar Fractures

Axial loading, flexion, and rotation can disrupt different parts of the vertebra and its supporting structures. Damage may involve the vertebral body, posterior elements, or ligaments, producing distinct patterns of structural compromise. Recognizing the likely force helps clinicians interpret fracture morphology and assess whether the spine remains stable after trauma.

In a burst fracture, force can cause the vertebral body to fail in a way that pushes bone fragments into the spinal canal. This reduces the available space for neural structures and may increase the risk of neurological dysfunction. Imaging is therefore important for identifying canal compromise and guiding the urgency and type of treatment.

Stability depends on the pattern and extent of structural disruption rather than on the fracture location alone. Clinicians consider vertebral and posterior-element damage, supporting ligament injury, fracture morphology, and neurological findings. Classification systems organize these features, helping distinguish injuries suitable for observation or bracing from those more likely to require fixation.

Computed tomography characterizes the bony fracture pattern, including damage to the vertebral body and posterior elements. Magnetic resonance imaging adds information about supporting ligament injury and neural structures that may not be fully defined by bone imaging. Used together with clinical examination, these studies clarify stability and neurological risk for treatment planning.

Evaluation begins with a clinical examination that looks for neurological impairment and signs relevant to spinal stability. Imaging then defines the fracture morphology and identifies associated structural or ligamentous damage. Clinicians integrate these findings through classification and stability assessment before selecting observation, bracing, or surgical fixation, rather than relying on a single imaging feature.

The treatment pathway follows the assessed stability and neurological risk. Injuries with findings that support preserved stability may be managed with observation or bracing, while greater structural disruption or concerning neural risk can support surgical fixation. This individualized approach aims to guide healing, limit deformity, and reduce the possibility of neurological deterioration.
