Patient presents with complaints of low back pain, specifically localized to the sacroiliac joint region.  Symptoms include pain in the buttock, lower back, and may radiate to the groin, thigh, or hip.  Onset of sacroiliac joint pain is described as insidious or may be related to a specific incident such as a fall or lifting injury.  Pain is aggravated by activities such as prolonged standing, walking, climbing stairs, or transitional movements like getting in and out of a car.  Physical examination reveals tenderness to palpation over the sacroiliac joint, positive findings on provocative maneuvers such as the FABER test, compression test, distraction test, and Gaenslen's test.  Differential diagnosis includes lumbar disc herniation, sciatica, piriformis syndrome, and hip osteoarthritis.  Diagnostic imaging such as X-ray, MRI, or CT scan may be considered to rule out other pathologies.  Assessment: Sacroiliac joint dysfunction, right greater than left.  Plan: Conservative management including physical therapy focusing on core strengthening exercises, stretching, and stabilization techniques.  Patient education on proper body mechanics and activity modification.  Consider NSAIDs for pain management.  Referral to pain management specialist if symptoms persist or worsen.  Follow-up scheduled in two weeks to assess response to treatment.
