Cement augmentation in vertebral burst fractures.

Anton V Zaryanov, Daniel K Park, Jad G Khalil, Kevin C Baker, Jeffrey S Fischgrund,

As a result of axial compression, traumatic vertebral burst fractures disrupt the anterior column, leading to segmental instability and cord compression. In situations with diminished anterior column support, pedicle screw fixation alone may lead to delayed kyphosis, nonunion, and hardware failure. Vertebroplasty and kyphoplasty (balloon-assisted vertebroplasty) have been used in ... Read more >>
