Conditions We Treat
Sacroiliac (SI) Joint Dysfunction
What Is It?
Sacroiliac joint dysfunction occurs when there is abnormal motion or inflammation of the sacroiliac joint, where the spine meets the pelvis.
Because of its location, SI joint pain can closely mimic lumbar spine or hip disorders.
Symptoms
- Low back pain near the posterior pelvic dimples
- Pain in the buttock, hip, or thigh
- Pain worsened by prolonged sitting, standing, or stair climbing
- Often one-sided and aggravated by weight-bearing activities
Diagnosis
- Physical exam using SI joint provocation tests
- Imaging studies to rule out other lumbar or hip pathology
- Diagnostic SI joint injection with local anesthetic to confirm the pain source
Treatment
Conservative Options:
- Activity modification and rest
- Physical therapy focusing on pelvic stabilization, alignment, and flexibility
Interventional Options:
- SI joint injections with corticosteroids, prolotherapy, or PRP
- Radiofrequency ablation of SI joint nerves
Surgical Options:
- SI joint fusion reserved for severe, refractory cases
