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)
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)
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)
BACKGROUND Several construct options exist for transverse acetabular fracture fixation. Accepted techniques use a combination of column plates and lag screws. Quadrilateral surface buttress plates have been introduced as potential fixation options, but as a result of their novelty, biomechanical data regarding their stabilizing effects are nonexistent.(More)
OBJECTIVE To examine the correlation between syndesmotic malreduction and functional outcome. DESIGN Prospective evaluation of bilateral computed tomography scans and functional outcome scores. SETTING Level I regional trauma center. MATERIALS AND METHODS From January 1, 2004, to December 31, 2006, 107 of 681 operatively treated ankle fractures(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)
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)
OBJECTIVE To evaluate the clinical and radiographic results associated with the use of a percutaneous suprapatellar (SP) portal and accompanying instrumentation for tibial intramedullary nail (IMN) insertion using a semiextended approach. DESIGN Prospective, nonrandomized, nonconsecutive study. SETTING Level 1 trauma center. PATIENTS AND METHODS From(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)
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)
