RESUMEN
PURPOSE: To evaluate the complications associated with anterior pelvic external fixation and the success of this device in maintaining reduction when used in conjunction with sacroiliac screws. METHODS: Through a retrospective clinical study at an academic Level I Trauma Center, 129 patients fit the criteria for inclusion with a mean duration of anterior pelvic external fixation of 62 days and mean follow-up of 360 days. Charts were reviewed for complications postoperatively. The symphysis diastasis, vertical displacement and posterior displacement of each hemipelvis were quantified from pelvic radiographs. RESULTS: Of the 129 patients receiving anterior pelvic external fixation, 14 (10.9 %) presented to an emergency department for problems with their anterior pelvic external fixation. Of these 14 patients, 7 (5.4 %) required readmission, all for infectious concerns necessitating IV antibiotics. 6 (4.7 %) required formal operative debridement and device removal. 13 patients (10.1 %) had superficial pin site infections successfully treated with oral antibiotics. Reduction was maintained (rated as fair, good or excellent) in all patients with radiographic follow-up (n = 74, average radiographic follow-up of 216 days) following removal of their anterior pelvic external fixation. 38 patients (30.4 %) had their anterior pelvic external fixation removed in clinic, while 87 (69.6 %) had formal removal in the operating room. CONCLUSION: While previous data suggest high complication rates in definitive anterior pelvic external fixation, we present the largest cohort of patients receiving anterior pelvic external fixation and sacroiliac screws, demonstrating a low complication rate while maintaining reduction of the pelvic ring. In addition, we found that these devices could be reliably removed in a clinic setting.
