Sacroiliac sprain: an overlooked cause of back pain

Since sacroiliac sprain syndrome is not a common disorder, it may be overlooked as a cause of low back pain. Even though the sacroiliac joint is very strong, it can incur painful injury. The diagnosis of sacroiliac sprain syndrome requires more than just tenderness on palpation of the sacroiliac area. Certain maneuvers, such as Patrick's test and the sacroiliac compression test, are useful in establishing the diagnosis. Proper treatment consists of bed rest, heat, nonsteroidal anti-inflammatory drugs and muscle relaxants. Physical therapy and manipulation may also help. In recalcitrant cases, injection of the sacroiliac joint with a corticosteroid and a local anesthetic can be effective.
