CT guided percutaneous fixation of sacroiliac fractures in trauma patients.

BACKGROUND Open reduction and internal fixation of unstable pelvic fractures has been advocated to minimize complications and avoid further injury. We have recently performed CT guided percutaneous fixation of sacroiliac joints as an alternative to open repair. METHODS From May 1, 1998 to April 30, 1999, our Level II trauma center admitted 76 patients with pelvic fractures, all due to blunt trauma. Twenty patients with unstable sacroiliac fracture-distractions underwent 22 percutaneous fixation procedures under general anesthesia in the radiology department by the third hospital day. Procedure times averaged 82 minutes. Localization with CT guidance was performed by the radiologist using 3-D images followed by percutaneous screw placement by the orthopaedic surgeon. RESULTS There was minimal procedural blood loss and no post-procedural wound complications. There was one operative delay due to respiratory difficulties and one postoperative death unrelated to the pelvic fracture. All patients were mobilized on the first post-procedural day. CONCLUSION CT guided fixation of unstable pelvic fractures minimizes blood loss during a short procedure with few subsequent complications and allows early mobilization of the patients.
