Minimally invasive treatment with radiofrequency ablation and kyphoplasty for avascular necrosis of the spine in sickle cell disease: illustrative case.

Background: Avascular necrosis (AVN) of the spine is a rare sequela of chronic sickle cell disease (SCD) in which the shape of the sickled red blood cells interfere with the normal vascular supply of vertebral bodies. In this report, the authors describe a case of progressive spinal AVN treated with radiofrequency ablation (RFA) and kyphoplasty for the patient's persistent lower back pain.

Observations: A 38-year-old male with long-standing spinal AVN due to SCD had been managed conservatively with hydroxyurea and oral opioid analgesics for several years until breakthrough episodes of low-back pain began to occur with an inability to perform activities of daily life.
