Short-segment posterior fixation provides partial kyphosis correction and earlier pain relief, but the functional outcome at 2 years is similar. Early activity to the point of pain tolerance can be safely allowed.
Despite the use of less restrictive criteria, no brace, and early activity as tolerated, the results are similar to those obtained with more restrictive protocols. The presence of vertical lamina fracture, spinous process fracture, and transverse process fracture are not contra--indications. Activity restriction and bracing may be important for pain control but probably does not change the long-term result.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
