Arthritis Diagnosis

Arthritis Diagnosis

Arthritis Diagnosis
Doctors diagnose arthritis with a medical history and physical exam to check for joint inflammation and deformity. Your doctor may also order lab work like blood, urine and joint fluid tests. X-rays are commonly used to check for cartilage loss in the affected joints, narrowing of the space between bones and the existence of nodules. Following the initial diagnosis, x-rays are also used to mark your arthritis progression.

    Although there is no cure for most types of arthritis, early diagnosis and proper management are important, particularly for inflammatory types of arthritis. Early use of disease-modifying drugs can change the course of rheumatoid arthritis. If you have symptoms of arthritis, which may include pain, aching, stiffness, and swelling in or around the joints, see your doctor and begin appropriate management of your condition.

    In addition to X-rays, CT scans, and/or MRIs, your doctor might order blood tests to help rule out infection, types of arthritis other than osteoarthritis, cancer, and other problems. Most people with straightforward signs and symptoms of arthritis may not require more than an X-ray. However, your physician will make that determination in order to help ensure that a more serious underlying disorder does not go undiagnosed and untreated.

    The degree of severity of arthritis on an X-ray often does not correlate with symptoms. A person with a terrible looking X-ray of the knee may be completely symptom-free. Likewise, a person who shows minimal arthritis on an X-ray may be experiencing severe pain. This does not mean that one person is stoic and the other is a complainer. Different people have higher or lower thresholds for pain, depending on their body biochemistry and the synapses within their brain. Many factors influence the pain threshold in a given individual, including social support, depression, painful stimuli, and other potential biochemical and neuromodulating factors.

    Someone who has severe cartilage degeneration may not have reached the point where the surrounding structures have become irritated and inflamed. If only cartilage is involved, there will be no pain because cartilage doesn't have any nerve endings. By contrast, the person with minimal X-ray findings of cartilage degeneration may just be unlucky enough to have the cartilage degrade in a pattern that allows pressure to be placed on the surrounding structures, leading to irritation and inflammation. Perhaps the synovium was already inflamed, or perhaps the bone was already compensating for increased pressure, and a tiny bone spur hooked a piece of the joint capsule or irritated a ligament.

    X-rays are more than sufficient for diagnosing arthritis. They can show bone spurs (osteophytes), subchondral cysts (the fluid-filled cysts that sometimes occur beneath the hardened bone), and joint space narrowing (the most classic finding in arthritis of the knee). As the cartilage degenerates, the bones move closer and closer together until they actually grind into each other. X-rays can mark this progression, although hopefully measures will be taken to slow or halt the progression once it is identified.

    Causes of Arthritis
    An x-ray can show the damage done to the bones of the joint due to loss of protective cartilage and bones rubbing directly against each other.

    Arthritis can be diagnosed with a simple physical exam and review of your medical history. If any questions remain, lab work and imaging may be indicated.

    In order to diagnose arthritis of the midfoot, the doctor will examine your foot and may order imaging studies. Weight-bearing x-rays can demonstrate loss of joint space in the midfoot joints, which is characteristic of arthritis.

    In the foot, arthritis most frequently occurs in the big toe, although it is also often found in the midfoot and ankle. A doctor can usually diagnose arthritis based on symptoms and standard x-rays.

    To diagnose big toe arthritis, your doctor will examine your foot for range of motion and gait analysis. X-ray evaluation is important to determine the amount of joint narrowing and bone spur formation in the joint.

    Arthritis X-rays
    Cartilage does not show up on x-rays. X-rays do show changes in the space between bones, such as in the knee joint, if cartilage is worn away by arthritis. This video gives more information on the knee and arthritis.
