Cement extravasation as a complication for kyphoplasty and vertebroplasty procedure: a retrospective analysis of 171 cases.

Aim Kyphoplasty and vertebroplasty are minimally invasive procedures used in bone augmentation following vertebral fractures when conservative management has failed. Cement injection could leak into surrounding structures leading to post-operative sequelae, which could be symptomatic. This study compared the rate and site of cement extravasation in vertebroplasty, kyphoplasty, and a combined approach.
