何謂骨關節炎？ 骨關節炎是一種關節疾病，是指關節內的組織隨著時間的推移而分解。這是最常見的關節炎類型，而且更常見於年長者。 骨關節炎患者通常有關節疼痛，而且在休息之後有短時間的關節僵直（難以移動）。最常累及的關節包括： 手（手指末端和拇指的起點和末端）。 膝蓋。 髖部。 頸部。 腰部。 骨關節炎對每個人的影響都有所不同。對有些人來說，骨關節炎不影響日常活動。而對其他人而言，骨關節炎會造成劇烈疼痛和殘障。
何謂類風濕性關節炎？ 類風濕性關節炎 是一種慢性（長期）疾病，大多數情況下影響關節，例如腕關節、手、腳、脊柱、膝蓋和下頜。類風濕性關節炎造成的炎症可導致關節： 疼痛。 腫脹。 僵直。 喪失功能。 因為是免疫系統攻擊健康的關節組織，類風濕性關節炎是一種自身免疫性疾病。正常情況下，免疫系統幫助保護身體免於發生感染和疾病。 類風濕性關節炎可能讓您感覺異常疲倦，偶爾會發燒，而且食欲下降。類風濕性關節炎還可能造成心、肺、血液、神經、眼睛和皮膚的其他醫療問題。 治療可以幫助患者過上充實的生活。
What is ichthyosis? Ichthyosis is a group of skin disorders. It leads to dry, itchy skin that appears scaly, rough, and red. The symptoms can range from mild to severe. Ichthyosis can affect only the skin, but sometimes the disease can affect internal organs, too.
What is Paget’s disease? Paget’s disease of bone is a chronic (long-lasting) disorder that causes bones to grow larger and become weaker than normal. Usually only one or a few bones have the disease. Many people with Paget’s disease do not have symptoms. However, the bone changes can cause: Bone pain. Misshapen bones. Broken bones (fractures). Problems in the joints near the bones with the disease. With treatment, many people can: Manage their symptoms. Improve pain. Control the effects of the disease.
What is osteoarthritis? Osteoarthritis is a joint disease that happens when the tissues in the joint break down over time. It is the most common type of arthritis and is more common in older people. People with osteoarthritis usually have joint pain and, after rest, stiffness (inability to move easily) for a short period of time. The most commonly affected joints include the: Hands (ends of the fingers and at the base and ends of the thumbs). Knees. Hips. Neck. Lower back. Osteoarthritis affects each person differently. For some people, osteoarthritis does not affect day-to-day activities. For others, it causes
What is osteonecrosis? Your bones are made up of living cells that need a blood supply to stay healthy. In osteonecrosis, blood flow to part of a bone is reduced. This causes death of bone tissue, and the bone can eventually break down and the joint will collapse. Osteonecrosis can happen to any bone, but most often it develops in the ends of long bones, such as the: Thigh bone. Upper arm bone. Less often, the bones of the elbows, ankles, feet, wrists, and hands are affected. When the disease involves part of a bone in a joint, it can
What is fibrous dysplasia? Fibrous dysplasia happens when abnormal fibrous (scar-like) tissue replaces healthy bone. The fibrous tissue weakens the bone over time, which can lead to: Broken bones. Bones that are misshapen (bowed or crooked). The disease can affect any bone in the body. Some people have no symptoms or only a few symptoms. Other people may have more symptoms. Although there is no cure for fibrous dysplasia, treatments may help to lessen pain, and physical therapy may help strengthen muscle and improve movement.
What are growth plate injuries? The growth plate is the area of tissue near the ends of long bones in children and teens that determines what length and shape the bone will be once it is done growing. Each long bone— the thigh bone, the bones in the forearm, and the bones in the hands and fingers—has at least two growth plates, one at each end. Once your child has finished growing, the growth plates close and are replaced by solid bone. The growth plates are weak areas of your child’s growing skeleton, making it easier to injure them. Injuries
What is rheumatoid arthritis? Rheumatoid arthritis (RA) is a chronic (long-lasting) disease that mostly affects joints, such as the wrist, hands, feet, spine, knees, and jaw. In joints, RA causes inflammation that leads to: Pain. Swelling Stiffness. Loss of function. Rheumatoid arthritis is an autoimmune disorder because the immune system attacks the healthy joint tissues. Normally, the immune system helps protect the body from infection and disease. RA may cause you to feel unusually tired, to have occasional fevers, and to have a loss of appetite. It also may cause other medical problems in the heart, lungs, blood, nerves, eyes
What are polymyalgia rheumatica and giant cell arteritis? Polymyalgia rheumatica and giant cell arteritis are closely linked inflammatory disorders. Some people have one of the disorders while others develop both of them. Polymyalgia rheumatica causes muscle pain and stiffness in the shoulders, upper arms, hip area, and sometimes the neck. Giant cell arteritis causes inflammation of arteries, especially those on each side of the head, scalp, and the aorta (the large artery that carries blood from the heart) and its main branches. The main symptoms of this disorder are: Headaches. Scalp tenderness. Jaw pain. Problems with your eyes, which may
