2

Serial radiograph monitoring

Regular imaging assessment of the vertebral pedicle defect to monitor for progression, stability, or development of spondylolisthesis. Monitoring frequency is based on symptom severity and risk factors.

3

Lumbar stabilization exercises

Targeted therapeutic exercises to strengthen the lumbar musculature and improve spinal stability around the affected pedicle. Emphasis on proprioception and dynamic lumbar support to protect the compromised segment.

Additional treatment options

Posterior spinal fixation

Surgical placement of screws and rods to provide mechanical stabilization when the pedicle defect compromises spinal integrity or when slippage is present. This prevents further vertebral displacement and allows for healing.

surgical

Anti-inflammatory medication

Short-term use of oral anti-inflammatory drugs to manage pain and inflammation associated with mechanical stress on the hypoplastic segment. Medication use should be time-limited to avoid adverse effects.

Bracing for spinal support

Use of a custom-fitted lumbar support brace during activities that stress the spine. Bracing provides external stability and may help prevent progression of any associated deformity.
