Follow-Up on Percutaneous Vertebroplasty Using PMMA in Osteoporotic Patients.

We reviewed the follow-up findings of patients who received percutaneous vertebroplasty, in order to understand the effects of vertebroplasty on following issues: pain relief, height restoration, wedge deformity correction, kyphosis correction, and other radiological findings found in follow up studies, such as new fractures. Generally, the pain relieving effect after vertebroplasty is long lasting except when new fracture occurred, or presence of other problems that caused the back pain. Height restoration and wedge deformity correction last for more than one year. The effect of kyphosis angle correction may vanish one year after procedure due to occurrence of new fracture in adjacent vertebral bodies.
