The treatment of the sacroiliac joint component to low back pain: a case report.

This case report describes the treatment of a patient who had symptoms and signs suggestive of a sacroiliac joint component of low back pain. The patient developed right-sided low back pain without provocation. He appeared to have sacroiliac joint dysfunction, excessive right hip lateral rotation, and limited right hip medial rotation. The patient's habit of crossing his right leg over his left leg while sitting was believed to have contributed to the excessive lateral hip rotation. After treating the sacroiliac joint and restoring symmetrical hip rotation, the patient no longer complained of low back pain. This case report suggests that asymmetrical hip rotation may contribute to what is often called a sacroiliac joint component of low back pain.
