Locked pubic symphysis is a rare form of pelvic injury that usually occurs after a lateral compression injury to
the pelvis, where the intact pubis is trapped behind the contralateral pubis. To the best of our knowledge, there
were 25 similar cases reported in the English literature since it was first described in 1952. We present a case
of locked pubic symphysis with a left iliac wing fracture and a left femur shaft fracture requiring open reduction
and internal fixation. We also reviewed previous reported cases of locked pubic symphysis and analysed the
pattern of presentation and guide to management of such injuries. We propose a classification system for
grading overlapping pubic symphysis that will provide a better guide to the management of such injuries.
