A sacral stress fracture is a hairline crack in the pelvic bone. This type of fracture is relatively uncommon but is usually caused by repetitive stress rather than a single accident. It usually affects the bottom of the pelvis, but can affect the front joint between the two pelvic bones.

Causes

This type of fracture is usually due to too much weight bearing exercise, for example dancing or running, or in some cases kicking in sports such as football. It can also happen to women after they have given birth if they do too much weight bearing exercise before they have rebuilt their core strength.

Symptoms

These include low back pain, pain in the buttocks, tenderness around the pelvis, and pain can also be felt in the hip or groin; this becomes worse with exercise but can also affect you while you are resting. You may also have weakness and restricted movement in the pelvis.

Diagnosis

A discussion of your symptoms will normally be backed up by X-rays, bone scans, CT scans and/or an MRI scan to confirm a diagnosis.

Treatment

Non-operative treatment: this includes resting, using ice (crushed and wrapped in towel) to reduce inflammation and taking anti-inflammatory medicine if advised by your doctor. Physiotherapy and a targeted rehabilitation programme can help you to gradually return to your everyday activities.
