Symphysis Pubis Dysfunction (SPD), also known as Pelvic Girdle Pain (PGP), is a condition that involves pain and discomfort in the pelvic region, specifically around the pubic symphysis. The pubic symphysis is a joint at the front of the pelvis where the two pubic bones meet. This joint is unique because it consists of a fibrocartilaginous disc that cushions between the bones, allowing for limited movement. SPD occurs when this joint becomes too relaxed and unstable, often due to hormonal changes during pregnancy, leading to significant pain and discomfort.

SPD is most commonly associated with pregnancy. During pregnancy, the body produces a hormone called relaxin, which helps to loosen the ligaments and joints in the pelvis to prepare for childbirth. While this is a natural and necessary process, in some cases, the pubic symphysis becomes overly relaxed, leading to instability and pain. Other factors that may contribute to the development of SPD include a history of pelvic trauma, previous pelvic surgeries, or a rapid increase in weight, which can add extra pressure on the pelvic joints.
The primary symptom of SPD is pain in the pelvic area, particularly around the pubic symphysis. This pain can range from mild discomfort to severe and debilitating pain. Other symptoms may include:
Diagnosing SPD typically involves a physical examination and a review of the patient's medical history. A healthcare provider may perform specific tests to assess pain levels and pelvic stability. In some cases, imaging tests such as ultrasound, X-rays, or MRI may be used to rule out other conditions and confirm the diagnosis.
The management and treatment of SPD focus on reducing pain, improving mobility, and stabilizing the pelvic region. Treatment options include:
