Pelvic ring disruption that results in overlapping dislocation with locking of pubic
symphysis is uncommon. A locked pubic symphysis occurs due to compression of
the pelvic ring, when the intact pubis getting trapped against the contralateral pubis.
The injury pattern is rarely seen in clinical practice, and only a small number of
patients with this injury have been reported in the English literature since its original
description by Eggers in 1952. A proposed mechanism of injury for a locked
symphysis is forced hyperextension and adduction of the hip resulting from a lateral
compression force to the pelvis. This injury causes a rupture of the ligaments that
normally stabilise the symphysis. The displaced pubis may lie either anterior or
posterior to the contralateral pubis. This injury is commonly associated with
urogenital injuries.Very little was written in literature about management of such
injuries though closed and open reduction techniques were described. Closed
reduction is difficult to achieve and also difficult to maintain. Open reductions are
associated with high rate of infections due to associated urogenital injuries.We report
a case of dislocation of pubic symphysis with locking in a 27 year old male patient.
He also had a rupture of urethra. We did an open reduction and tension band wiring
placing screws in a staggered fashion to maintain the reduction. He had urethroplasty
about three months later when the patient became fully ambulant. Four years
following the procedure the pelvis remained stable at the symphysis.
