BACKGROUND Pelvic fractures occur when there is high kinetic energy transfer to the patient such as would be expected in motor vehicle crashes, auto-pedestrian collisions, motorcycle crashes, falls, and crush injuries. High-force impact implies an increased risk for associated injuries to accompany the pelvic fracture, as well as significant mortality and(More)
STUDY DESIGN Retrospective chart review of 311 anterior cervical procedures. OBJECTIVES To assess the incidence and variables that predispose to an airway complication in a large series of anterior cervical surgical procedures. SUMMARY OF BACKGROUND DATA A rare but potentially lethal complication after anterior cervical spine surgery is respiratory(More)
OBJECTIVES To examine the effects of various iliosacral screw configurations with and without symphyseal plating on sacroiliac (SI) motion and hemipelvis stability in the vertically unstable pelvic model. DESIGN Biomechanical, human cadaver. SETTING Level 1 trauma center. INTERVENTION Hemipelvis and SI motion were analyzed on a Materials Testing(More)
STUDY DESIGN Human cadaveric. OBJECTIVES Compare the accuracy of electromagnetic field (EMF)-based image-guided lumbar pedicle screw insertion to conventional techniques using anatomic landmarks, and fluoroscopy. BACKGROUND Image-guided surgical systems that aid in spinal instrumentation seek to minimize radiation exposure and improve accuracy. EMF(More)
STUDY DESIGN Human cadaveric. OBJECTIVES Compare the accuracy of electromagnetic field (EMF)-based image-guided thoracic pedicle screw insertion to conventional techniques using anatomic landmarks and fluoroscopy. BACKGROUND Image-guided surgical systems that aid in spinal instrumentation seek to minimize radiation exposure and improve accuracy. EMF(More)
OBJECTIVE This study was designed to compare the accuracy, time, and radiation exposure during the insertion of intramedullary nail locking screws using either standard fluoroscopic assistance or an electromagnetic (EM)-based navigational system without fluoroscopy. DESIGN Prospective. SETTING Level I academic trauma center. METHODS Patients were(More)
OBJECTIVE Autograft bone obtained from the iliac crest remains the "gold standard" for spinal fusion. For various reasons, including previous harvesting or pelvic dysmorphism, the iliac crest bone graft may not be available to the spinal surgeon. We present a novel use of a common orthopedic procedure, intramedullary reaming, for obtaining autograft for(More)
OBJECTIVES To report on the radiographic and clinical outcome of symphyseal plating techniques, with specific attention to the incidence of implant failure, reoperation secondary to implant complication, and ability to maintain reduction of the pelvic ring. DESIGN Retrospective chart and radiographic review. SETTING Level 1 trauma center. PATIENTS A(More)
BACKGROUND Subtrochanteric fractures can be a treatment challenge. The substantial forces that this region experiences and the fact that the proximal fragment is frequently displaced make accurate reduction and internal fixation difficult. The purpose of this study was to evaluate a series of patients who had undergone clamp-assisted reduction and(More)
OBJECTIVE To describe the technique and results of stress examination with fluoroscopy under anesthesia (EUA) to determine stability and the need for operative stabilization of traumatic pelvic ring injuries. DESIGN Retrospective chart and radiographic review. SETTING Level I trauma center. SUBJECTS Skeletally mature patients with traumatic incomplete(More)
