Atypical APC-1 pelvic fracture presenting with pelvic instability: successful management with pubic symphysis fusion.

By definition, anteroposterior (AP) compression type 1 (APC-1) injury is a type of pelvic ring injury, which is widely acknowledged as 'stable'. Unstable forms of this injury are very rare and present a challenge for diagnosis and clinical management. Detailed herein is a man in his early 30s, referred to our institution with a 2-year history of pubic symphysis pain following a road traffic accident. Radiological investigation revealed an unstable APC-1 injury. This was subsequently managed with surgical reconstruction leading to the successful return of the patient to former function and recreational activities.
