Modeling of unstable pelvic fractures for 20 ° sagittally rotated pelvic displacement.

Early and accurate assessment of unstable pelvic fractures decreases mortality and morbidity by improving the outcomes of closed reduction surgery. In some circumstances (such as in developing countries or in acute trauma), accurate computed tomography (CT) 3D reconstructions are difficult to obtain and plain radiography must be relied upon for surgical planning. Therefore, a simulation model of pelvic displacement was evaluated as a basis for improving the assessment of pelvic fracture displacement from plain radiography images.

Printed three-dimensional anatomic templates for virtual preoperative planning before reconstruction of old pelvic injuries: initial results.

Background: Old pelvis fractures are among the most challenging fractures to treat because of their complex anatomy, difficult-to-access surgical sites, and the relatively low incidence of such cases. Proper evaluation and surgical planning are necessary to achieve the pelvic ring symmetry and stable fixation of the fracture. The goal of this study was to assess the use of three-dimensional (3D) printing techniques for surgical management of old pelvic fractures.

Long-term outcome of operative management of delayed acetabular fractures.

Background: Surgical treatment of acetabular fracture has long been a challenging area in the field of orthopedic trauma. The aim of this research was to investigate the operative methods for delayed acetabular fractures and to assess the operation results.

Methods: The operative approaches, procedures, results, and complications of the delayed acetabular fractures between 1995 and 2005 were retrospectively evaluated at Beijing Jishuitan Hospital.

Correlation analysis between plasma D-dimer levels and orthopedic trauma severity.

Background: The correlation between the plasma D-dimer level and deep vein thrombosis has not been conclusive in various studies. The aim of this research was to study the relationship between plasma D-dimer levels and the severity of orthopedic trauma by retrospective examination of orthopedic trauma cases.

Methods: Clinically acute trauma and non-acute trauma patients were selected and their plasma D-dimer levels were measured.
