Osteitis pubis


Osteitis pubis is characterized by non-infectious inflammation of the pubic symphysis. The most common causes are pregnancy/childbirth, high-level athletic activity, urological or gynecological surgery, trauma and psoriatic arthritis, though the etiology is sometimes unknown.

The x-ray findings are subchondral erosive change, joint irregularity and sclerosis, which may eventually lead to ankylosis. The main differential diagnoses are infection and hyperparathyroidism, the latter due to bone resorption.
