Diagnosis of ankylosing spondylitis in children needs to be based on clinical symptoms, physical examination, X-ray examination, laboratory tests and other methods.
1. Clinical symptoms: early onset of low back pain lasting at least three months, improvement of symptoms after activity, limitation of lumbar flexion, extension, lateral flexion and morning stiffness.
2. Physical examination: including Schober test, scoliosis test, occipital wall test, 4-word test and other physical examinations to assist diagnosis.
3. X-ray examination: the sacroiliac joint surfaces appear blurred, with irregular edges, narrowing, and disappearance of fusion.
4. Laboratory examination: Diagnosis is aided by detecting increased erythrocyte sedimentation rate, increased C-reactive protein count, and positive HLA-B27 test.
To summarize, if you suffer from ankylosing spondylitis in children, you should consult a doctor in time.
