Abstract
Percutaneous vertebroplasty is an effective procedure for the treatment of osteoporotic vertebral compression fractures, spinal metastasis and other pathologic spinal diseases. However, there has been no mention in the relevant literature of the use of percutaneous vertebroplasty for the treatment of spinal pseudarthrosis in ankylosing sponyloarthritis. A 58-year-old male with a long standing ankylosing spondylitis presented with increasing, intolerable and non-intractable back pain. There was a 16- month-old history of a non-significant minor fall. Various radiological imaging technicques showed spinal pseudarthrosis with extensive discovertebral destruction and fracture of the posterior elements at the level T11–T12. Under local anaesthesia, and through a transpedicular approach with the guidance of CT, the cannula of a large bore needle was introduced into the level of spinal pseudarthrosis. Bone cement was then instilled into the affected spinal level. Results were documented by spiral CT and with sagittal reconstructions. Extraosseous cement leakage was seen at the puncture site of the vertebra and in the epidural veins and the paravertebral vessels. However, the patient did not present any immediate or late neurological and systemic complications. Percutaneous vertebroplasty of spinal pseudarthrosis in patients with ankylosing spondylitis is an effective procedure for stabilization of the affected spine segments and pain management.
