Pelvic Instability


Pelvic instability can present at any age, but tends to decline with aging, due to stiffening of ligamentous tissues.
Our pelvic bones bear the weight of our upper body and distribute it through the hips and legs. The pelvis consists of the hip, sacrum and pubic bones all held together by ligaments. If ligaments are injured or overstretched, the pelvis loses its stability and begins to move excessively with physical activities.
It often presents in young females who are involved in sport that requires a high degree of mobility (such as dance or gymnastics). It can also present during pregnancy or post-partum, especially whilst still breast-feeding as the hormone, relaxin (which relaxes the pelvic ligaments in preparation for childbirth) is still circulating in the system.

What Causes it?

There may or may not be a history of injury that causes the pain. Often pain will commence insidiously and be associated with prolonged postures rather than moving or physical activity.
The underlying cause of pain is deformation of structures in the spine and pelvis (joint and ligaments) due to excessive range of motion without the necessary muscular control. The joints are held at or near their end range of motion, which stresses and stretches the retaining ligaments.


Symptoms include pain in the sacral-iliac joints, lower lumbar spine and pubic pain. There may be radiation of pain to the groin or hip. Pain when rolling over in bed, climbing stairs, and getting out of the bath are highly suggestive of the condition.


A physical examination and a series of provocative tests (physical maneuvers), are used to diagnose pelvic instability.
