Abstract
INTRODUCTION: The optimal method of fixation of symphyseal disruptions in pelvic ring injuries and post-operative rehabilitation is still debated. Options include two-hole, multi-hole and multiplanar plates. Post-operative rehabilitation can range from non-weight bearing bilaterally to full weight-bearing with crutches. Locking symphyseal plates have recently been introduced. There is a paucity of literature evaluating their use in such injuries. We present the first clinical case series of symphyseal diastasis managed with locking plates. METHODS: A retrospective analysis of a single centre case series between August 2008 and December 2011 was conducted. A total of 11 patients; 2 females and 9 males with a mean age of 42 years were included. The mean radiological follow up was 27 weeks. Radiological failure and need for revision were evaluated. RESULTS: 4 patients sustained their injury as a result of a motorcycle accident, 3 patients following a car accident, 2 fell from a height and 2 had crush injuries. 9 patients had other concomitant injuries. The mechanism of injury was classified as anterior-posterior compression injury in 6 patients, vertical shear in 4 patients and combined mechanism in 1 patient. 6 patients required posterior pelvic fixation. Patients were mobilised fully or partially weight bearing. One patient had a significant radiological failure. All patients were asymptomatic at last follow-up and none required revision surgery. CONCLUSION: Our series represents the first published clinical series of patients with symphyseal diastasis managed with locking plates. We have found the use of locking plates across the pubic symphysis to be safe with low complication rates despite early weight bearing.
