Chronic progressive degeneration of the stress-bearing portion of a joint, with bizarre hypertrophic changes at the periphery. It is probably a complication of a variety of neurologic disorders, particularly TABES DORSALIS, involving loss of sensation, which leads to relaxation of supporting structures and chronic instability of the joint. (Dorland, 27th ed)
Surgical reconstruction of a joint to relieve pain or restore motion.
Partial or total replacement of a skeletal joint.
Replacement of the ANKLE JOINT.
Replacement of the ELBOW JOINT.
Partial or total replacement of one or more FINGERS, or a FINGER JOINT.
Replacement of the hip joint.
Replacement of the knee joint.
Surgical techniques used to correct or augment healing of chondral defects in the joints (CARTILAGE, ARTICULAR). These include abrasion, drilling, and microfracture of the subchondral bone to enhance chondral resurfacing via autografts, allografts, or cell transplantation.
Paired sense organs connected to the anterior segments of ARTHROPODS that help them navigate through the environment.
Proteins synthesized by organisms belonging to the phylum ARTHROPODA. Included in this heading are proteins from the subdivisions ARACHNIDA; CRUSTACEA; and HORSESHOE CRABS. Note that a separate heading for INSECT PROTEINS is listed under this heading.
Arthropods, other than insects and arachnids, which transmit infective organisms from one host to another or from an inanimate reservoir to an animate host.
Venoms from animals of the phylum ARTHROPODA. Those most investigated are from SCORPIONS and SPIDERS of the class Arachnidae and from ant, bee, and wasp families of the INSECTA order HYMENOPTERA. The venoms contain protein toxins, enzymes, and other bioactive substances and may be lethal to man.
Members of the phylum Arthropoda, composed of organisms having a hard, jointed exoskeleton and paired jointed legs. It includes the class INSECTS and the subclass ARACHNIDA, many species of which are important medically as parasites or as vectors of organisms capable of causing disease in man.
Endoscopes for visualizing the interior of a joint.
Endoscopic examination, therapy and surgery of the joint.
A dermal inflammatory reaction produced under conditions of antibody excess, when a second injection of antigen produces intravascular antigen-antibody complexes which bind complement, causing cell clumping, endothelial damage, and vascular necrosis.
Disorders of the quality of speech characterized by the substitution, omission, distortion, and addition of phonemes.
Any visible result of a procedure which is caused by the procedure itself and not by the entity being analyzed. Common examples include histological structures introduced by tissue processing, radiographic images of structures that are not naturally present in living tissue, and products of chemical reactions that occur during analysis.
Chemically synthesized structures which functionally resemble natural cells.
The in vitro fusion of GENES by RECOMBINANT DNA techniques to analyze protein behavior or GENE EXPRESSION REGULATION, or to merge protein functions for specific medical or industrial uses.
Theory and development of COMPUTER SYSTEMS which perform tasks that normally require human intelligence. Such tasks may include speech recognition, LEARNING; VISUAL PERCEPTION; MATHEMATICAL COMPUTING; reasoning, PROBLEM SOLVING, DECISION-MAKING, and translation of language.
The shifting and or tilting of implanted artificial lens resulting in impaired vision.
Prosthetic replacements for arms, legs, and parts thereof.
Devices intended to replace non-functioning organs. They may be temporary or permanent. Since they are intended always to function as the natural organs they are replacing, they should be differentiated from PROSTHESES AND IMPLANTS and specific types of prostheses which, though also replacements for body parts, are frequently cosmetic (EYE, ARTIFICIAL) as well as functional (ARTIFICIAL LIMBS).
