Rod cantilever techniques.

Abstract

Cantilever beam fixation techniques have a broad application in spine surgery, including the treatment of thoracolumbar spinal deformities. There are traditionally three cantilever beam fixation types described: fixed moment arm, nonfixed moment arm, and applied moment arm. In practice, however, most constructs are applied in a hybrid fashion. The basic tenets of cantilever beam fixation are provided in this article.
