One-stage posterior eggshell osteotomy and long-segment pedicle screw fixation for ankylosing spondylitis kyphosis combined with acute thoracolumbar vertebral fracture

This study explores a surgical technique for patients with ankylosing spondylitis who also suffer a fracture in their spine and have a hunched back. The technique involves a one-time surgery from the back where surgeons reshape the fractured vertebra (eggshell osteotomy) and stabilize the spine with screws and rods. The goal is to see if this surgery is safe and effective for fixing the fracture, correcting the hunched back, and improving the patient's pain and quality of life. The study looks back at the records of 20 patients who had this surgery to see how well it worked and what complications occurred.

• 1
  The study found that the surgery significantly improved patients' pain, disability, kyphosis (hunchback), and spinal alignment.
• 2
  Most patients also experienced improved nerve function after the surgery.
• 3
  All patients achieved bone fusion, meaning the spine healed properly at the fracture site, and there were no issues with the screws or rods loosening.
