Anatomic Determinants of Sacral Dysmorphism and Implications for Safe Iliosacral Screw Placement.
BACKGROUND Upper sacral segment dysplasia increases the risk of cortical perforation during iliosacral screw insertion. Dysmorphic sacra have narrow and angled upper osseous corridors. However, there is no validated definition of this anatomic variation. We hypothesized that pelves could be quantitatively grouped by anatomic measurements. METHODS One hundred and four computed tomography (CT) ...
متن کاملIntracanal Sacral Nerve Impingement Following Percutaneous Iliosacral Screw Pelvic Fixation
Percutaneous iliosacral screws are useful in treating vertical posterior pelvic fractures and iliosacral disruptions. Iliosacral screws are far less invasive than spinopelvic fixation, and result in much lower morbidity. However, safe placement of the iliosacral screws is technically difficult and highly dependent on fracture reduction and adequate fluoroscopy. Inaccurate placement can result i...
متن کاملPrevalence of sacral dysmorphia in a prospective trauma population: Implications for a "safe" surgical corridor for sacro-iliac screw placement
BACKGROUND Percutaneous sacro-iliac (SI) screw fixation represents a widely used technique in the management of unstable posterior pelvic ring injuries and sacral fractures. The misplacement of SI-screws under fluoroscopic guidance represents a critical complication for these patients. This study was designed to determine the prevalence of sacral dysmorphia and the radiographic anatomy of surgi...
متن کاملPercutaneous iliosacral screw placement using a radiolucent drive.
Percutaneous iliosacral screw placement is a standard stabilisation technique for pelvic fractures. It is a demanding operative technique. Various methods of guidance are currently available. We present a quick and simple fluoroscopy-guided technique using a radiolucent drive designed for distal locking of intramedullary nails. From January 2008 to December 2009, 27 screws were inserted using t...
متن کاملThe human sacrum and safe approaches for screw placement.
The human sacrum is the target of lumbosacral instrumentation and decompression procedures. Such surgical interventions require detailed knowledge of the anatomy of the human sacrum. The aim of this study was to measure surgically relevant parameters. Several factors, including the one-piece composition of the sacrum, the angles of the sacral pedicles and the anteroposterior diameter of the sac...
