Zusammenfassung: | Background
Injection of cement during vertebroplasty and kyphoplasty can leak into surrounding structures and could be symptomatic.
Purpose
To identify the sites and incidence of cement extravasation after kyphoplasty and vertebroplasty, and to evaluate their impacts on clinical outcomes.
Material and Methods
A retrospective review of 316 patients treated with kyphoplasty and vertebroplasty; 411 cases were included (223 kyphoplasty and 188 vertebroplasty). Cement extravasation was evaluated postoperatively by computed tomography (CT) scan of the spine. Clinical outcomes were assessed by visual analog scale (VAS) and Oswestry Disability Index (ODI).
Results
There was a statistically significant difference in the incidence rate of cement extravasation between vertebroplasty and kyphoplasty groups (P |
