Two-hole plate fixation for traumatic symphysis pubis diastasis

Techniques for managing traumatic diastasis of the pubic symphysis include bed rest, hip spica casting, pelvic slings, external fixation, and internal fixation. We report herein our experience with 14 consecutively managed patients in whom we successfully stabilized traumatic pubic diastasis with a single two-hole plate fixation. The average age of the 13 men and one woman was 30 years; followup averaged 17 months. Most of the patients had associated injuries (Injury Severity Score average, 19). Nine patients had concomitant disruption of the sacroiliac joint requiring either delayed open reduction and internal fixation or prolonged skeletal traction; among the five remaining patients, time to mobilization (bed to chair) averaged 1 day. There were no complications attributable to the procedure; i.e., no infections, and no failures of fixation. In this small series of patients early two-hole plate fixation of the traumatic diastasis of the pubis satisfactorily restored the disrupted anterior pelvic ring, contributed to early mobilization of the patients, and made reduction of a concomitantly disrupted sacroiliac joint easier, whether accomplished by skeletal traction or open reduction and internal fixation during a second procedure.
