Technique of pedicle screw fixation of the lumbosacral spine

Abstract

Pedicle screw fixation is a safe and effective technique for fixating the spine for the promotion of fusion. It is most often performed in the lumbosacral spine to treat instability. The most common indication is degenerative instability; however, congenital, traumatic, neoplastic, or infectious causes of instability can also be treated effectively. Likewise, pedicle screw fixation can be performed in the thoracic and cervical regions. With few exceptions, the basic principles for placement are the same as for the lumbosacral region. This article offers a detailed description of our technique for placing lumbosacral pedicle screws.
