Osteomyelitis of the Pubic Symphysis: What to Know

The pubic symphysis joins the two halves of the pelvis at the front. Infection there may produce groin or lower abdominal pain, tenderness over the joint, pain when turning in bed, limping, or difficulty climbing stairs. Fever can occur but is not always present. Symptoms can resemble a muscle strain, pelvic joint inflammation, or a urinary problem, so examination and imaging are useful. Blood tests and, in selected cases, sampling of fluid or tissue help identify the cause.

Seek a prompt clinical assessment, particularly when pain is worsening or walking is becoming difficult. Treatment may include prescribed antimicrobial medicine, activity modification, pain relief chosen for your health needs, and follow-up imaging or blood tests. Use walking support only as advised, because too much loading can aggravate pain while too little movement may cause stiffness. Do not self-treat with leftover antibiotics. If an abscess, unstable joint, or unhealthy tissue is found, a surgical team may discuss drainage or removal of infected tissue.

Get urgent care for rapidly worsening pelvic pain, inability to stand or walk, fever with shaking chills, faintness, confusion, repeated vomiting, or new weakness or numbness in either leg. Emergency assessment is also appropriate for loss of bladder or bowel control, severe abdominal pain, or a wound with spreading redness or drainage.

Could the pain be coming from the pubic symphysis rather than the hip or urinary tract? Which scan is appropriate? How much weight can I put through my legs? How will you check that treatment is controlling the infection? When should physiotherapy begin?
