[Progress of research on percutaneous fixation for the treatment of pelvic ring and acetabular injuries].

Percutaneous pelvic fixation is possible with the advances in intraoperative fluoroscopic imaging and other technologies. Percutaneously inserted screws in medullary pubic ramus,iliac wing, and iliosacral bone can stabilize pelvic or acetabular disruptions directly mean while can diminish operative blood loss, shorten operative time, and allow patient's early activity. Complications associated with open surgical procedures are similarly avoided by using percutaneous techniques. Stable and safe percutaneous fixation techniques depend on accurate closed reduction, excellent intraoperative fluoroscopic imaging, and detailed preoperative planning. A thorough knowledge of pelvic osseous anatomy, injury patterns, deformities, and the related intraoperative imagery techniques are essential for doctors to fulfill the operation of percutaneous pelvic fixation. This paper presents an overview of the technique of percutaneous surgery of the pelvis and acetabulum.
