Arthritis of the Hand

Arthritis of the Hand Cause Disease Trauma Diagnosis Symptoms Treatment After Surgery Research on the Horizon Print this article The hand and wrist have multiple small joints that work together to produce motion. This gives the fine motion needed to thread a needle or tie a shoelace. When the joints are affected by arthritis, activities of daily living can be difficult. Arthritis can occur in multiple areas of the hand and wrist. It can have multiple causes. It is estimated that one out of every five people living in the United States has at least one joint with signs or symptoms of arthritis. About half of arthritis sufferers are under age 50. Arthritis is the leading cause of disability in the United States. It typically occurs from either disease or trauma. The exact number of people with arthritis in the hand and wrist is not known. Cause Cartilage works as nature's "shock absorber." It provides a smooth gliding surface for the joint. All arthritic joints lose cartilage. When the cartilage becomes worn or damaged, or is lost due to disease or trauma, the joint no longer has a painless, mobile area of motion. The body attempts to make up for the lost cartilage. It produces fluid in the joint lining (synovium), which tries to act like a cushion, like water in a waterbed. But it also causes the joint to swell. This restricts motion. The swelling causes stretching of the joint covering (capsule), which causes pain. Over time, if the arthritis is not treated, the bones that make up the joint can lose their normal shape. This causes more pain and further limits motion. Top of page Disease When arthritis occurs due to disease, the onset of symptoms is gradual and the cartilage decreases slowly. The two most common forms of arthritis from disease are osteoarthritis and rheumatoid arthritis. Osteoarthritis is much more common and generally affects older people. It appears in a predictable pattern in certain joints. Rheumatoid arthritis has other system-wide symptoms and may be passed from parent to child (genetically). Top of page Trauma Fractures within the finger joints. When arthritis is due to trauma, the cartilage is damaged. People of any age can be affected. Fractures, particularly those that damage the joint surface, and dislocations are the most common injuries that lead to arthritis. An injured joint is about seven times more likely to become arthritic, even if the injury is properly treated. Top of page Arthritis does not have to result in a painful or sedentary life. It is important to seek help early so that treatment can begin and you can return to doing what matters most to you. Diagnosis Bone scans of the hands. A doctor can diagnose arthritis of the hand by examining the hand and by taking X-rays. Specialized studies, such as magnetic resonance imaging (MRI), are usually not needed. Sometimes a bone scan is helpful. A bone scan may help the doctor diagnose arthritis when it is in an early stage, even if X-rays look normal. Arthroscopy pictures of the wrist joint. The white objects are some of the wrist bones as seen through the arthroscope. The metal rod is an arthroscopic probe with a tip measuring 2 mm. It can be seen moving between two of the wrist bones that have a ligament tear between them. Normally, the bones are close together and cannot be moved apart. Arthroscopy is another way to look at the joint by direct inspection. During an arthroscopic procedure, the surgeon inserts a small camera into the joint to look inside. It provides the clearest picture of the joint without having to make a large incision. However, this is an invasive procedure and should not be used as a routine diagnostic tool. Top of page Symptoms Pain Early symptoms of arthritis of the hand include joint pain that may feel "dull," or a "burning" sensation. The pain often occurs after periods of increased joint use, such as heavy gripping or grasping. The pain may not be present immediately, but may show up hours later or even the following day. Morning pain and stiffness are typical. As the cartilage wears away and there is less material to provide shock absorption, the symptoms occur even with less use. In advanced disease, the joint pain may wake you up at night. Pain might be made worse with use and relieved by rest. Many people with arthritis complain of increased joint pain with rainy weather. Activities that once were easy, such as opening a jar or starting the car, become difficult due to pain. To prevent pain at the arthritic joint, you might adapt the way you use your hand. Swelling Thumb extension deformity. This patient has lost mobility at the base of the thumb due to arthritis. The next joint closer to the tip of the thumb has become more mobile than normal to make up for the arthritic joint. Normally, the thumb does not come to a right angle with the rest of the hand. When the affected joint is subject to greater stress than it can bear, it may swell in an attempt prevent further joint use. Changes in Surrounding Joints In patients with advanced thumb base arthritis, the neighboring joints may become more mobile than normal. Warmth The arthritic joint may feel warm to touch. This is due to the body's inflammatory response. Crepitation and Looseness There may be a sensation of grating or grinding in the affected joint (crepitation). This is caused by damaged cartilage surfaces rubbing against one another. If arthritis is due to damaged ligaments, the support structures of the joint may be unstable or "loose." In advanced cases, the joint may appear larger than normal (hypertrophic). This is usually due to a combination of bone changes, loss of cartilage, and joint swelling. Cysts Mucous cyst of the index finger. When arthritis affects the end joints of the fingers (DIP joints), small cysts (mucous cysts) may develop. The cysts may then cause ridging or dents in the nail plate of the affected finger. Top of page Treatment Nonsurgical Treatment Treatment options for arthritis of the hand and wrist include medication, splinting, injections, and surgery. * How far the arthritis has progressed * How many joints are involved * Your age, activity level and other medical conditions * If the dominant or non-dominant hand is affected * Your personal goals, home support structure, and ability to understand the treatment and comply with a therapy program Medications Medications treat symptoms but cannot restore joint cartilage or reverse joint damage. The most common medications for arthritis are anti-inflammatories, which stop the body from producing chemicals that cause joint swelling and pain. Examples of anti-inflammatory drugs include over-the-counter medications such as Tylenol and Advil and prescription drugs such as Celebrex. Glucosamine and chondroitin are widely advertised dietary supplements or "neutraceuticals." Neutraceuticals are not drugs. Rather, they are compounds that are the "building blocks" of cartilage. They were originally used by veterinarians to treat arthritic hips in dogs. However, neutraceuticals have not yet been studied as a treatment of hand and wrist arthritis. (Note: The U.S. Food and Drug Administration does not test dietary supplements. These compounds may cause negative interactions with other medications. Always consult your doctor before taking dietary supplements) Injections When first-line treatment with anti-inflammatory medication is not appropriate, injections may be used. These typically contain a long-acting anesthetic, similar to novacaine but longer lasting, and a steroid that can provide pain relief for weeks to months. The injections can be repeated, but only a limited number of times, due to possible side effects, such as lightening of the skin, weakening of the tendons and ligaments and infection. Splinting Injections are usually combined with splinting of the affected joint. The splint helps support the affected joint to ease the stress placed on it by activities. Splints are typically worn during periods when the joints hurt. They should be small enough to allow functional use of the hand when they are worn. Wearing the splint for too long can lead to muscle wasting (atrophy). Muscles can assist in stabilizing injured joints, so atrophy should be prevented. Surgical Treatment If nonsurgical treatment fails to give relief, surgery is usually discussed. There are many surgical options. The option chosen should be one that has a reasonable chance of providing long-term pain relief and return to function. It should be tailored to your individual needs. It is important that the treating physician is well versed in current surgical techniques. Thumb base fusion using a plate and screws. If there is any way the joint can be preserved or reconstructed, this option is usually chosen. When the damage has progressed to a point that the surfaces will no longer work, a joint replacement or a fusion (arthrodesis) is performed. Finger joint prosthesis. Joint fusions provide pain relief but stop joint motion. The fused joint no longer moves; the damaged joint surfaces are gone, so they cannot cause symptoms. Joint replacement attempt to provide pain relief and functional joint motion. As with hip and knee replacements, there have been significant improvements in joint replacements in the hand and wrist. The replacement joints are made of materials similar to those used in weightbearing joints, such as ceramics or long-wearing metal and plastic parts. The goal is to improve the function and longevity of the replaced joint. Most of the major joints of the hand and wrist can be replaced. A surgeon often needs additional training to perform the surgery. As with any evolving technology, the long-term results of the hand or wrist joint replacements are not yet known. Early results have been promising. Talk with your doctor to find out if these implants are right for you. Top of page After Surgery After any type of joint reconstruction surgery, there is a period of recovery. Often, you will be referred to a trained hand therapist, who can help you maximize your recovery. You may need to use a postoperative splint or cast for awhile after surgery. This helps protect the hand while it heals. During this postoperative period, you may need to modify activities to let the joint reconstruction heal properly. Typically, pain medication you take by mouth is also used to reduce discomfort. It is important to discuss your pain with your doctor so it can be adequately treated. Length of recovery time varies widely and depends on the extent of the surgery performed and multiple individual factors. However, people usually can return to most if not all of their desired activities in about three months after most major joint reconstructions. Top of page Research on the Horizon Increasingly, doctors are focusing on how to preserve the damaged joint. This includes getting an earlier diagnosis and repairing joint components before the entire surface becomes damaged. Arthroscopy of the small joints of the hand and wrist is now possible because the equipment has been made much smaller. There have been encouraging results in cartilage repair and replacement in the larger joints such as the knee, and some of these techniques have been applied to the smaller joints of the hand and arm. In addition, stem cell research may be an option to regenerate damaged joint surfaces.

Joints are places in your body where two bones come together. Arthritis is a problem that causes damage to the normal joint surfaces. These junctions have special surfaces to allow smooth motion. This smooth surface is cartilage, and when the cartilage is damaged, arthritis is the condition that results. There are two types of arthritis that commonly affect the fingers. These are osteoarthritis and rheumatoid arthritis. * Osteoarthritis, also called wear-and-tear arthritis, is the most common type of finger arthritis. In people with osteoarthritis, the normal cartilage is steadily worn away, exposing bare bone at the joints. The most frequently affected joints in the hand are the knuckles of the mid-finger and fingertip (the PIP and DIP joints), and the joint at the base of the thumb. * Rheumatoid Arthritis Rheumatoid arthritis causes a different type of joint destruction. Rheumatoid arthritis is a systemic disease that can cause a number of problems. Among these, rheumatoid arthritis can cause inflammation of the soft-tissue surrounding joints. The most commonly affected joints in the hand are the knuckles at the base of the fingers (the MCP joints). What are the symptoms of finger arthritis? Symptoms of finger arthritis include: * Joint pain * Swelling * Stiffness * Loss of motion Patients with osteoarthritis often develop lumps or nodules around the knuckles of the fingers. These lumps are called Heberden's nodes (when around the more distant knuckle) or Bouchard's nodes (when around the closer knuckle), and actually consist of bone spurs around the joints. These knuckles often become enlarged, swollen, and stiff. People often complain that their rings do not fit, or can't be removed. Patients with rheumatoid arthritis often have the aforementioned symptoms, but can also have more complex deformities of the hands. The fingers may begin to shift from their normal position, and drift away from the thumb. What are the treatments for finger arthritis? Early treatments of finger arthritis are focused on managing the symptoms in an effort to avoid surgery. Treatment options include: * Anti-Inflammatory Medications These medications can help treat the pain of finger arthritis, and also help decrease inflammation and swelling around the joints. * Hand Therapy Hand therapy, usually performed by an occupational therapist, is helpful to maintain motion and prevent stiffening of the joints. * Ice & Heat Treatment Joint stiffness and range of motion can be improved by ice and heat treatments. * Splints Splinting helps to relax and rest the joints. Splinting should be done for limited periods of time to allow for relief without allowing the joint to stiffen. If these treatments fail, then surgery may be necessary. In the fingers, several procedures may be done, including removing the bone spurs, fusing the joint, and replacing the joint. The most common surgery is a finger joint fusion. This procedure holds the joint in a fixed position to prevent any further motion at the affected joint. While the joint is then stiff forever, the pain is usually alleviated. Furthermore, during finger joint fusion surgery, your doctor can straighten any deformity and remove bone spurs.
