The sacroiliac joint (SIJ) is the joint that connects the sacrum to the pelvis. It plays a crucial role in transferring loads from the spine to the lower extremities and in maintaining pelvic stability.
Dysfunction or inflammation of the sacroiliac joint can cause pain in the lower back, buttocks, hip, or even the thigh, often mimicking low back pain or sciatica. Symptoms are typically aggravated by prolonged standing, walking, climbing stairs, or changing positions.
Treatment is primarily conservative and includes physiotherapy, stabilization exercises, pain management, and, when symptoms persist, targeted sacroiliac joint injections. These injections serve both diagnostic and therapeutic purposes, providing significant pain relief and improving overall function and quality of life.
