Ankylosing Spondylitis: A clinical form of Psoriatic Arthritis
By swell the vertebra, the spine tends to become stiff, painful with movement, sensitive to pressure, the spines of the vertebrae affected are occasionally excel and is accompanied by abdominal pain, abscess formation, and varying levels of paralysis.
One of the most common causes for spondylitis is inflammation autoimmune, as is the case of ankylosing spondylitis.
Certain infectious processes can cause spondylitis, classically extrapulmonary tuberculosis, in the case of Pott's disease.
Ankylosing spondylitis (AS) is a rheumatic inflammatory process, chronic, which primarily affects the spinal joints in general and in charge of linking-sacroiliac spine to the pelvis, in particular.
Inflammation can also occur in other joints of the limbs, as ankles, knees, wrists, hips, etc., being most prevalent in the lower extremities. Most cases start between 15 and 30 years with a predominance of males: 3-6 per woman.
Early diagnosis is essential (even before it is displayed involvement on radiographs) and determining the degree of involvement.
Spondylitis usually occurs slowly and gradually, with episodes of pain in the lumbar region radiating into the buttocks and even the back of the thigh, blending well with the famous sciatica. The pain increases at night, causing the time out of bed a striking and painful rigidity, thus limiting mobility.
The probability that a person under 45 years with back pain for more than three months duration has a Spondylarthritis is less than five percent.
