Outcome of Surgical Treatment of AO Type C Pelvic Ring Injury / 대한고관절학회지

PURPOSE: To evaluate the radiologic and clinical outcomes of AO type C pelvic ring injury and identify the prognostic factors. MATERIALS AND METHODS: We studied 53 patients who were treated for AO type C pelvic ring injury from January 2002 to February 2010. Mean age and mean follow-up duration were 42.4 years and 14 months, respectively. We had 8 cases of AO type C1-1, 19 cases of C1-2, 11 cases of C1-3, 6 cases of C2 and 9 cases of C3 injury. We analyzed type of fracture, displacement, method of fixation and associated injuries. Radiologic outcome was evaluated with Matta and Saucedo criteria and clinical outcome was evaluated using Majeed score. RESULTS: The average Majeed score was 86.2 distributing as 36 excellent cases, 15 good cases and 2 fair cases. Using radiologic Matta and Saucedo criteria, patients were divided as 31 excellent cases, 17 good cases and 5 fair cases. There was no significant difference between the outcomes of anterior, posterior and antero-posterior fixation. Neurologic injury was the reason for an unsatisfactory functional outcome. We identified two cases with complication, one with postoperative infection and the other with nonunion following anterior-posterior fixation. CONCLUSION: Satisfactory radiologic and clinical outcomes were obtained with open reduction and internal fixation in the management of AO type C pelvic ring injuries. Neurologic injuries affected the clinical outcome.

Clinical Outcome of AO Type C Pelvic Ring Injury / 대한정형외과학회잡지

PURPOSE: To study the clinical results of AO type C pelvic ring injuries and identify the prognostic factors. MATERIALS AND METHODS: 25 patients were treated for C type pelvic ring fractures between January 1995 and August 2002. The injury mechanism, associated injuries, time from injury to surgery, ICU care, Injury Severity Score, fracture site of posterior ring, displacement, surgical method, and complications were analyzed. Radiological and clinical evaluations of the results were conducted using the Majeed's score. Of the 25 patients, 16 were male, 9 were female, with an average age of 41.6 years. All except one patient had associated injuries and 12 patients had neurological complications. There were 17, 7 and 1 case of C1, C2 and C3 type injuries respectively. Twenty three cases underwent surgical treatment. RESULTS: The average Majeed's score was 66.6 points, and 15 patients (60%) had good or excellent results. The complications included 3 cases of non-union and 1 case of SI joint infection were complications. The clinical results were worse in those patients with neurological symptoms. CONCLUSION: Satisfactory results were obtained after surgical treatment of C type pelvic ring injuries. Neurological injuries affected the clinical outcome and appropriate fixation of the anterior ring was needed for stable fixation of C type pelvic ring injuries.
