Posterior spinal epidural abscess: an unusual complication of vertebroplasty.
OBJECTIVE
Complications after vertebroplasty are rare. There are few reported infectious complications requiring surgical management such as corpectomy with anterior reconstruction and posterior stabilization, although we have not seen any reports about epidural abscess in the literature. We present a patient in whom posterior epidural abscess developed after vertebroplasty in which drainage and antibiotherapy were required for treatment.


METHODS
A 70-year-old female with a painful T12 osteoporotic compression fracture underwent percutaneous vertebroplasty using polymethylmethacrylate without complication. One week after vertebroplasty, however, she had fever and increased back pain. On clinical examination, soft tissue abscess formation was determined at the vertebroplasty site. This was drained surgically and antibiotic treatment was started. At follow-up, she had progressive neurological deterioration (paraparetic) on the 18th day after abscess drainage. MRI of the thoracolombar spine revealed posterior spinal epidural abscess at the T11/12 level. Partial laminectomy and drainage were performed. She had complete neurological recovery in the follow-up period.


CONCLUSIONS
An epidural abscess, which is an unusual complication of vertebroplasty, represents a medical and surgical emergency. Treatment is generally urgent surgical drainage combined with antibiotics. The patient should be evaluated in detail for systemic infectious disease and comorbid conditions before the vertebroplasty procedure.
