M96.5

Clinical Causes: Radiation therapy directed near the spine, especially for cancers of the chest, abdomen, or pelvis Radiation-induced damage leading to weakening of vertebral bones Fibrosis or scarring of the surrounding tissues, affecting spinal alignment Changes in bone growth and remodeling in younger individuals following radiation exposure

Key Symptoms: Uneven shoulder or hip levels Visible curvature of the spine noticeable when viewed from the back or side Persistent back pain or discomfort Postural imbalance, such as leaning to one side Reduced range of motion in the back Potential neurological symptoms if the spinal cord or nerve roots are affected

Diagnosis Path: Diagnosis of postradiation scoliosis involves a combination of medical history, physical examination, and imaging studies. Healthcare providers review the patient's previous radiation treatments and assess spinal alignment. X-rays are essential for confirming the degree of spinal curvature and noting any radiation-induced damage to the vertebrae. MRI scans may be used to evaluate soft tissue involvement and neural elements. The severity of scoliosis is typically classified based on the Cobb angle measurement, which quantifies the degree of spinal curvature.

Treatment Protocols: Management strategies for postradiation scoliosis depend on the severity of the curvature and associated symptoms. Treatment options include: - Observation: Mild cases with minimal curvature might only require regular monitoring. - Physical therapy: Exercises to strengthen back muscles, improve posture, and enhance flexibility. - Pain management: Use of medications or modalities to reduce discomfort. - Orthotic support: Braces to help correct or prevent progression of the curve, especially in younger patients. - Surgical intervention: Severe curves that cause significant functional impairment or pain might necessitate spinal fusion or other surgical procedures. Early diagnosis and tailored treatment plans can help improve quality of life and prevent worsening of the condition.
