Methods to Check for Ankylosing Spondylitis

There are various methods to check for ankylosing spondylitis, including physical examination, laboratory tests, and imaging examinations. It is recommended that patients visit the hospital promptly and undergo relevant tests under the guidance of a doctor. Here are the details:

I. Physical Examination

1. General Condition: Observe whether the patient's gait is abnormal, such as limping or stiffness in the lumbar region.

2. Lumbar Range of Motion: Judge by measuring the amplitude of lumbar flexion and extension. Normal individuals usually have a range of around 70°, while patients with ankylosing spondylitis may have a significantly reduced range.

3. Sacroiliac Joint Tenderness: Press the iliac bone edges on both sides of the buttocks with your hand. If pain occurs, it may indicate the presence of sacroiliac joint inflammation.

II. Laboratory Tests

These mainly include blood routine, C-reactive protein, rheumatoid factor, and HLA-B27 antigen detection. Elevated C-reactive protein, positive rheumatoid factor, and positive HLA-B27 antigen all suggest the possibility of ankylosing spondylitis.

III. Imaging Examinations

1. CT Scan: It can clearly show the narrowing and fusion of the intervertebral disc space, and can also detect changes such as masses in the paravertebral soft tissue or spinal canal stenosis.

2. X-ray Plain Film: In the early stage, the sacroiliac joint may appear blurred with a brush-like shadow. In the late stage, it may manifest as osteoporosis, ligament calcification, and small pelvic tilt deformity.

3. MRI Examination: It has a high sensitivity for early lesions and can detect sacroiliitis earlier and accurately reflect its severity, which is of great significance for diagnosis.

In addition to the above methods, radionuclide bone imaging and ultrasonography can also be used as auxiliary diagnostic methods. If the disease is confirmed, it is necessary to follow the doctor's instructions and use medications such as Celecoxib Capsules and Diclofenac Sodium Sustained-Release Tablets to relieve symptoms. Surgical treatment may be necessary in severe cases.
