The subcristal pelvic external fixator: technique, results, and rationale.
We report a new technique for pelvic external fixation that we have developed as an alternative to the anterosuperior (Slätis) and the anteroinferior (supra-acetabular) type pelvic external fixator configurations. The method principally differs from the other techniques by virtue of the subcristal positioning of the pins and offers advantages in terms of easier pin placement, less skin irritation, less pin tract infection and loosening, and less interference with hip flexion, while allowing dressing, sitting, and walking. Between 1992 and 2006, we successfully used subcristal pelvic external fixators as the definitive fixation device for 20 patients with pelvic ring disruptions. The only complications encountered were superficial pin tract infections in 4 patients (20%) who were successfully treated with wound care and antibiotics.
