Sacroiliac Joint Fractures

Sacroiliac joint fractures occur in the sacroiliac joint in the space that links the pelvis to the spine at the very bottom of the back. It aids the human body in movement by allowing weight to be shifted from the legs to the upper part of the body while also enabling twisting movements. Fractures into the sacroiliac joint (diastasis) result from traumatic injuries in which a sudden force is applied to the pelvis, such as falling and landing on the buttocks. This kind of fracture leaves the patient with pain in the lower back, ranging from an ache to a sharp pain.

The soreness may spread to the buttocks and groin areas, causing a pain in testicles among males. The pain may also have a grinding sensation in the joint and result in complete inability to bear weight. Other symptoms include difficulty turning over in bed and getting in and out of a car.


Fractures into the sacroiliac joint can be found on regular x-rays in the emergency room. Symptoms of a mild sacroiliac joint fracture or stress fracture, such as tenderness or back pain, can also be attributed to other ailments, making it hard to diagnose a fracture in this area.  Therefore, one should consult a specialized doctor like Dr. Louis when looking for treatment. In most cases, surgery is not necessary for a sacroiliac joint fracture, and most doctors will recommend rest or protected weight bearing.   In patients with prolonged pain, sacroiliac joint injections with pain-relieving medication can be used to minimize the soreness.
