Instability (specifically in the Symphysis Pubis)

Pelvic instability is a condition that commonly occurs in pregnant women, but it can also develop as a result of trauma. This means that men can also experience pelvic instability. The pelvis consists of several bones:

• One ilium on each side
• The sacrum at the back
• The pubic bones at the front

Pelvic instability occurs when the ligaments connecting the pelvic bones become weakened or damaged. Around one to nine percent of pregnant women experience pelvic instability. In men and non-pregnant women, this condition is much less common.

Around the 20th week of pregnancy, the body produces the hormone relaxin. This hormone causes the ligaments in the pelvis to become more flexible, allowing the pelvic bones to move more independently of each other. This increased flexibility helps create more space for the baby to pass through during childbirth. However, when the ligaments become too loose, a condition called symphysiolysis can occur. The symphysis is the joint in the middle of the pubic bones, and symphysiolysis refers to the separation of this joint – although this is rare.

You may experience the following symptoms:

• Pain usually occurs when making sudden movements or when you begin to feel fatigued

Hip and pelvis – Treatment of pelvic instability

Treatment is usually coordinated between the gynaecologist and a physical medicine specialist. During pregnancy, it is important for the pregnant woman to be well informed. Some helpful tips to manage pelvic instability include: avoiding frequent changes in activity, reducing strain, limiting twisting movements, and taking regular breaks to rest.

Strengthening exercises after childbirth can also help support recovery. Additionally, you may consider using a brace or support belt to relieve symptoms and provide extra stability.
