Received 4 April 2003; accepted 24 April 2003 ABSTRACT Posterior transpedicular screw fixation has been widely used for the management of unstable lumbosacral spine caused by trauma, degenerative conditions, congenital defects and neoplasms. Knowledge of the pedicle diameters of the first sacral vertebra is crucial for safe placement of the screws. Thirty dry sacral specimens (18 male, 12 femal...

Thoraco lumbar fractures are grave injuries of utmost concern. If left untreated may result in marked morbidity and disability to the patient. Most polytrauma patients suffer from spine which turn can be associated with neurological deficits makes treatment an important entity. Hence present study was undertaken efficacy, evaluate clinical radiographic results, advantages, complications facilit...

BACKGROUND Accurate placement of pedicle screw during Anterior Transpedicular Screw fixation (ATPS) in cervical spine depends on accurate anatomical knowledge of the vertebrae. However, little is known of the morphometric characteristics of cervical vertebrae in Chinese population. METHODS Three-dimensional reconstructions of CT images were performed for 80 cases. The anatomic data and screw ...
