Stress fracture of sacrum - Buttock pain

The sacrum is the large triangular-shaped bone that is located at the base of the spine.

Causes of a stress fracture of the sacrum

Stress fractures are almost always caused by overuse; continuous use applies constant pressure on the sacrum, which over time weakens it and makes it more prone to injury. Athletes that participate in activities such as long or middle distance running are more likely to suffer from a stress fracture of the sacrum.

Symptoms of a stress fracture of the sacrum

The most common symptom of a sacral stress fracture is pain in the buttocks and lower back; this usually becomes more severe during exercise and subsides when exercise ceases. Other symptoms include swelling and a restricted range of movement.

Treating a stress fracture

The most common treatment for a stress fracture is rest; the sacrum should be allowed to heal fully before exercise is resumed. Exercise should be gradually built-up once healing is complete. Physiotherapy and strengthening exercises may be beneficial to increase strength in the area and improve movement and flexibility; these exercises will also help to condition the body and make it more resistant to injury in the future.
