The pubis forms the anterior hip bone and the two pubic bones meet at the pubic symphysis anteriorly. Osteitis pubis from repetitive microtrauma at the pubic symphysis produces midline groin pain that is a component of athletic pubalgia. The pubic ramus is fractured in pelvic ring injuries and insufficiency fractures in osteoporotic patients produce acute groin pain that can be confused with hip joint pathology. The obturator foramen, formed by the pubis and ischium, transmits the obturator neurovascular bundle.
Common in older adults after a low fall, causing groin pain and difficulty walking; most heal without surgery.
Painful inflammation and stress reaction of the pubic bones at the symphysis, seen in kicking and running sports.
