Osteitis Condensans ilii
The cause is unknown, may be related to pregnancy, trauma, infection and strain. Female labor stability of the sacroiliac joint is affected, the ligament relaxation, and iliac bone and joint local under the abnormal stress increased; plus sacral inclination angle increases, the pelvis forward tilt, attached to the ilium ilium traction on the ligament affects bone blood supply, make local blood supply decrease bone density changes caused by the emergence of.
Mainly for the lumbosacral region or lower back pain, occasionally in the hip and thigh appear to lower radiation pain. Patients with plump, and lumbosacral angle is larger, the sacral spine muscle is in nervous state, pelvic separation test and positive "4" test. The blood cells of patients with normal sedimentation rate, and non bacterial inflammation.
1 X-ray examination
Iliac cortex on X-ray plain film visible near the joint sclerosing bone was changed, compact shape, is located in the sacroiliac joint 1/2, and a triangle; the sacroiliac joint space neat, clear, and no bone articular surface damage syndrome. Unilateral more common, also has bilateral.
When necessary, feasible CT and MRI examination, and the differential diagnosis of tumors.
This disease should be associated with early ankylosing spondylitis sacroiliac joint tuberculosis, and pyogenic arthritis of sacroiliac joint identification. Ankylosing spondylitis is more bilateral disease, more common in young men, the blood cells of patients with sedimentation rate fast, joint space widening, serrated, advanced joint space disappeared, sacroiliac joint fusion.
In the non operation therapy. Mild symptoms, may be appropriate to rest in bed, the bed is elastic corset protection; serious symptoms can take painkillers, and support for protection, for pain relief after the patients were encouraged to do abdominal exercises, and continue with elastic waist protection. On the intractable pain, may consider the fusion of sacroiliac joint operation.
Generally good prognosis.
