Arthrogryposis: Joint contractures that develop before birth and are evident at birth. With arthrogryposis there is a lack of the normal range of motion in one or more joints. In normal embryonic development, joints can be seen moving by 8 weeks of gestation. This motion of joints is essential to the proper development of the joints and structures around them. Limitation of joint motion before birth leads to joint contractures and arthrogryposis. Prenatal limitation of joint mobility can result from neurologic deficits, muscle defects, connective tissue defects, and fetal crowding (in which there is not enough room for the fetus to move around freely in the womb).
- Arthrogryposis multiplex congenita (AMC)
Arthrogryposis multiplex congenita (AMC): A disorder that develops before birth (prenatal), is present at birth (congenital), and is characterized by reduced mobility of many (multiple) joints. In AMC the range of motion of the joints in the arms and legs is usually limited or fixed. Joints affected may include the shoulders, elbows, wrists and fingers […]
Arthroscope: A thin flexible fiberoptic scope which is introduced into a joint space through a small incision in order to carry out diagnostic and treatment procedures within the joint. An arthroscope is about the diameter of a drinking straw. It is fitted with a miniature camera, a light source and precision tools at the end […]
A surgical technique in which a tube-like instrument is inserted into a joint to inspect, diagnose, and repair tissues. It is most commonly performed in patients with diseases of the knees or shoulders.
Arthrosis: An arthrosis is a joint, an area where two bones are attached for the purpose of motion of body parts. An arthrosis (joint) is usually formed of fibrous connective tissue and cartilage. Joints are grouped according to their motion: a ball and socket joint; a hinge joint; a condyloid joint (a joint that permits […]
- Artic health
Artic health: Health in the vast geographic region widely surrounding the North Pole, an area that encompasses all or portions of Alaska, Canada, Greenland/Denmark/Faroe Islands, Iceland, Norway, Sweden, Finland, and Russia. The populations of these countries, including their indigenous inhabitants such as the Aleut, Inuit, and Saami, have to cope with extreme climatic conditions and […]
