Abstract
Objective. To specify techniques of transcutaneous transpedicular vertebroplasty for lumbar vertebra injury in patients with osteoporosis. Material and Methods. Ninety five patents aged 55 to 82 years with uncomplicated injuries to lumbar vertebrae associated with osteoporosis were operated on. Specific features of surgery depended on radiological morphological parameters of the injured vertebra revealed by preoperative X-ray examination. Standard radiography and computer-aided tomography were used. Results. Persistent antalgic effect was observed in 96.3 % of operated patients. In 7 (7.3 %) cases conventional transcutaneous vertebroplasty was associated with cement extravasation beyond vertebra limits. Patients having such X-ray picture of injury underwent a modified technique of vertebroplasty with bilateral transpedicular injections of precalculated bone cement volume into posterior and anterior fragments of the injured vertebra. Conclusion. The choice of vertebroplasty technique should be made with account for radiological morphometric parameters of the injured vertebra optimally based on CT findings.
