Increased iliac angle
Introduction
Introduction The inclination of the humerus angle increases, the pelvis tilts forward and downward, and the ligament attached to the tibia affects the blood supply of the tibia, which reduces the local blood supply and causes the density of the bone to change. Osteitis condensans ilii is an increase in bone density in the ear joint between the tibia and the tibia. Can be single or double side. Symptoms can disappear or resolve on their own after half a year to several years, and the denseness of the tibia disappears.
Cause
Cause
(1) Causes of the disease
The cause is unknown.
(two) pathogenesis
The cause is unknown and may be related to pregnancy, trauma, infection and strain. The stability of the ankle joint is affected during female delivery, the surrounding ligament is loose, and the abnormal stress on the humerus itself and the joint is increased. In addition, the sacral angle is increased, the pelvis is tilted forward and downward, and attached to the tibia. The traction of the ligament on the tibia affects the blood supply of the tibia, which reduces the local blood supply and causes the density of the bone to change.

an examination

Blood routine CT examination
The disease should be differentiated from early ankylosing spondylitis, ankle joint tuberculosis and suppurative ankle arthritis.
Ankylosing spondylitis is mostly bilateral lesions, more common in male youth, patients with rapid blood cell sedimentation rate, joint space widened, serrated, late joint space disappeared, ankle bone fusion.
Diagnosis
Differential diagnosis
Mainly manifested as pain in the lumbosacral or lower back, occasionally in the lower part of the buttocks and the back of the thigh, the radiation pain to the buttocks, but not the root pain of the lower extremity. The patient's body was full, and the lumbosacral angle was large. The sacral spine muscle was mostly in a state of tension, and the pelvic separation test and the "4" test were positive. The patient's blood cell sedimentation rate is normal and there is no bacterial inflammation.
Generally no difficulty, can be diagnosed according to medical history, physical signs and imaging findings.
