• Ankylosis — A marked diminution or complete loss of mobility in a joint, occurring due to an intracapsular bony or fibrous fusion, caused by chronic inflammatory processes (rheumatism, arthritis), infections, severe trauma, or prolonged immobilization in bed or a plaster cast.
• Ankylosing — Causing, promoting, or accompanying ankylosis; causing progressive stiffening and permanent immobilization of the joints through fibrous or bony fusion. It is commonly used to describe severe forms of chronic autoimmune arthritis affecting the axial skeleton.
• Arthropathy — A generic term used to designate any disease, suffering, or organic or functional condition that localizes within and affects a joint, regardless of its underlying cause. This extensive medical category includes destructive degenerative processes (such as arthrosis), inflammatory conditions (arthritis), or secondary joint disorders driven by systemic illnesses like diabetes or psoriasis.
• Arthropyosis — An acute or chronic infectious pathological process characterized by the accumulation of pus inside a joint cavity, associated with the rapid destruction of the synovial membrane and protective cartilage. This severe condition, clinically termed purulent septic arthritis, is caused by the penetration of pyogenic germs (bacteria) directly through trauma, non-sterile surgical interventions, or via the bloodstream from another infectious focus in the body.
• Arthrosyphilis — A specific joint localization of the Treponema pallidum infection, characterized by inflammatory, degenerative, or destructive manifestations within bone and synovial structures, occurring as a complication in the secondary or tertiary stages of syphilis. This rare infectious pathology can take the form of acute arthritis, chronic bilateral hydrarthrosis (Clutton's joints in congenital forms), or severe destructive neurological degradation (Charcot joint in tabes dorsalis).
• Arthrosis — A chronic degenerative joint disease characterized by the progressive degradation and gradual destruction of the protective cartilage covering bone ends, accompanied by modifications of the subchondral bone and the formation of marginal bone growths called osteophytes. This pathology, closely linked to natural aging, repeated trauma, or excessive mechanical stress, causes persistent pain, nocturnal joint stiffness, and severe reduction of functional mobility.
• Aurotherapy — A therapeutic method consisting of the administration of organic compounds or soluble salts based on gold (chrysotherapy) in the treatment of severe chronic conditions, such as rheumatoid arthritis, lupus erythematosus, or other autoimmune diseases. The substances act by inhibiting lysosomal enzymes and reducing the severe inflammatory response.
