Osteitis pubis is characterised by non-infectious inflammation of the pubic symphysis.
Presentation is typically with varying degrees of lower abdominal and pelvic pain.
Although the aetiology is sometimes unknown, the commonest causes are:
- pregnancy / childbirth 2
- high-level of athletic activity
- urological or gynaecological surgery 2
- psoriatic arthritis
The x-ray findings are subchondral erosive change, joint irregularity and sclerosis, which may eventually lead to ankylosis. Positive findings usually are not apparent until 4 weeks after the onset of symptoms
MRI may demonstrate parasymphyseal bone marrow oedema although this finding may also be seen in asymptomatic individuals. Symphyseal fluid and peripubic soft-tissue oedema during initial stages may also bee seen 1.
Bone scans may be negative but can demonstrate intense signal uptake at the pubis symphysis.
Treatment and prognosis
Treatment is symptomatic and mainly relies upon rest.
