Pelvic ring disruption that results in a locked pubic symphysis is an unusual injury. A locked pubic symphysis is defined as a compression of the pelvic ring, with the intact pubis becoming trapped against the contralateral pubis. Although the injury pattern is well recognized in clinical practice, to the best of our knowledge, only eight patients with this injury have been reported in the English-language literature1-8 since its original description by Eggers in 19523. A proposed mechanism for a locked symphysis is forced hyperextension and adduction of the hip1 resulting from a lateral compression force to the pelvis. This injury causes a rupture of the ligaments that normally stabilize the symphysis. The superior, anterior, and posterior ligaments are weak, while the arcuate (or inferior) ligament is thought to confer most of the stability to this fibrocartilaginous joint9. After rupture of these ligaments, the displaced pelvic bone may lie either anterior or posterior to the contralateral pubis. Because of the direction and magnitude of this pubic displacement, the injury pattern has been associated with urethral injury2,3,5,7. Although an initial attempt at closed reduction has been advocated6, there is otherwise only limited guidance in the literature regarding the treatment of a locked symphysis. One technique for closed reduction involves using the femur as a lever by locking it in flexion, abduction, and external rotation. The iliofemoral ligaments are thought to hold the femoral head within the acetabulum and to allow reduction with a gentle abduction and rocking motion of the affected extremity3. Authors have cited a risk of femoral fracture in association with this reduction technique and therefore have advocated external rotation of the hemipelvis with a force applied mostly to the …
