Symphysis pubis dysfunction

Symphysis pubis dysfunction (SPD) is a condition that causes excessive movement of the pubic symphysis, either anterior or lateral, as well as associated pain, possibly because of a misalignment of the pelvis. Most commonly associated with pregnancy and childbirth, it is diagnosed in approximately 1 in 300 pregnancies, although some estimates of incidence are as high as 1 in 50.

SPD is associated with pelvic girdle pain and the names are often used interchangeably.

The main symptom is usually pain or discomfort in the pelvic region, usually centered on the joint at the front of the pelvis (the pubic symphysis). Some sufferers report being able to hear and feel the pubic symphysis and/or sacroiliac, clicking or popping in and out as they walk or change position. Sufferers frequently also experience pain in the lower back, hips, groin, lower abdomen, and legs. The severity of the pain can range from mild discomfort to extreme pain that interferes with routine activities, family, social and professional life, and sleep. There have been links between SPD and depression due to the associated physical discomfort. Sufferers may walk with a characteristic side-to-side gait and have difficulty climbing stairs, problems with leg abduction and adduction, pain when carrying out weight bearing activities, difficulties carrying out everyday activities, and difficulties standing.

A diagnosis is usually made from the symptoms, history, and physical exam alone. After pregnancy, MRI scans, x-rays and ultrasound scanning are sometimes used. Patients typically initially report symptoms to a midwife, chiropractor, obstetrician, general practitioner, physiotherapist or an osteopath. On seeing a health professional, patients should expect to receive a thorough physical examination to rule out other lumbar spine problems,such as a prolapsed disc or pelvic and or pubis joint misalignment, or other conditions such as iliopsoas muscle spasms, urinary tract infections and Braxton Hicks contractions.
