#articular

• Abarticular — A medical term used to describe structures, inflammatory processes, or symptoms located outside a joint, but in its immediate vicinity (tendons, ligaments, bursa). Abarticular rheumatism (such as tendinitis or bursitis) manifests as periarticular pain without affecting the cartilage or internal synovial membrane of the joint itself.
• Acampsia — A clinical pathological state manifested by extreme muscle rigidity, total inflexibility, or the complete loss of mobility in a joint or limb, preventing any form of flexion. This severe condition is often the result of bony ankylosis, retractile fibrous scarring following major trauma, or advanced spastic neurological disorders, requiring intensive physiotherapy or corrective surgery.
• Acromionitis — An acute or chronic inflammatory pathological process localized at the level of the acromion or its immediately adjacent periarticular structures (such as the subacromial bursa and rotator cuff tendons). This structural condition is most frequently triggered by repeated microtraumas, occupational or athletic mechanical overuse, or localized degenerative phenomena, clinically manifesting through intense pain during arm elevation, partial functional impairment of the shoulder, localized edema, and acute tenderness upon palpation.
• Acropachydermia — A rare pathological clinical condition, congenital or acquired, characterized by the symmetric hypertrophic thickening of the skin and soft tissues of the extremities (hands and feet), often associated with subperiosteal osteoarticular deformities of the phalanges. This severe structural phenomenon impairs cutaneous elasticity and fine joint mobility, frequently manifesting within complex neuroendocrine syndromes, such as pachydermoperiostosis (Touraine-Solente-Golé syndrome), or as a secondary paraneoplastic reaction in chronic pulmonary diseases.
• Alveolo-palatal — Pertaining to the region between the upper alveolar ridge and the hard palate, relating to this anatomical zone, or articulated in this space. In phonetics, it describes consonants produced by placing the body of the tongue close to the hard palate and the tip of the tongue behind the alveolar ridge, such as the sibilant fricatives or affricates found in languages like Mandarin, Polish, or Russian.
• Amyoplasia — A specific and most common form of arthrogryposis multiplex congenita, characterized by the defective muscular development or congenital absence of certain skeletal muscle groups, which are structurally replaced by fatty and fibrous tissue. This severe condition causes joint stiffness, symmetrical limb contractures, and reduced mobility from birth, typically without affecting the patient's intellectual development.
• Ankylodactyly — A rare congenital malformation or acquired condition (following severe trauma, burns, or destructive rheumatic processes), characterized by marked stiffness, total immobilization, or pathological fusion of the joints of one or more fingers or toes, leading to the loss of flexion and extension function.
• 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.
• Antermit — Situated, placed, or manifested before the emission of a signal or an articulated sound; relating to the preliminary phase of phonetic articulation. Broadly, the term defines a transitional state of controlled pause or a micro-temporal interval preceding a major acoustic phenomenon, serving to prepare the resonating structure.
• Antirheumatic — Preventing, combating, mitigating, or treating rheumatism; a medication or active substance prescribed to reduce joint or muscular pain, stiffness, and inflammation. In modern clinical practice, the term gathers a wide range of therapeutic pharmaceutical preparations, ranging from classical nonsteroidal anti-inflammatory drugs and corticosteroids to genetically modified biological agents that slow down connective tissue degradation.
• Antistreptolysin — The articulated form or lexical variant currently used for antistreptolysin O (ASLO); a specific antibody produced by the human immune system in response to infection with group A beta-hemolytic streptococci. This serological protein neutralizes streptolysin O (a hemolytic toxin released by the bacterium) and is quantitatively determined in laboratories via the ASLO titer to diagnose post-streptococcal complications such as acute rheumatic fever or glomerulonephritis.
• Certain — Precisely indicated, determined, chosen, or fixed from among a larger number of possibilities; which is of a certain kind or is in a known but not directly named state; (indefinite pronoun) a certain one, an individual or object taken abstractly.
• Apico-alveolar — Pertaining to the tip of the tongue and the alveoli of the upper teeth; a consonant or sound articulated by placing or bringing the tip of the tongue close to the upper alveolar ridge (e.g., certain variants of the consonants t, d, or s across various languages).
• Articular — Pertaining to or characteristic of a joint; structurally located at the junction of two or more bones. In a clinical sense, it describes anatomical elements, pathological modifications, or inflammatory and degenerative processes localized within the capsules, cartilages, or ligaments of the locomotor system.
• Articulation — The act of articulating sounds, parts, or bony structures and its result; physiological process of altering the vocal tract to produce speech; a mobile mechanical assembly made of correlated parts; plural form of the adjective 'articular'. In a structural sense, it describes the method of functionally connecting the elements of a system.
• Arthria — The normal physiological capacity to articulate speech sounds clearly, distinctly, and correctly through the coordination of the vocal apparatus organs (tongue, lips, palate, vocal cords). In speech therapy and phonetics, the term represents the opposite of anarthria or dysarthria, defining the structural correctness of the mechanical word pronunciation process.
• Arthrocele — A hernia, cystic swelling, or abnormal dilation of a joint capsule, caused by the excessive accumulation of synovial fluid or through the structural weakening of periarticular tissues. In clinical practice, this cystic mass can compress adjacent nerves and blood vessels, generating discomfort, local pain, and partial reduction in the mobility of the affected bony segment.
• Arthrocentesis — An invasive medical procedure consisting of puncturing a joint cavity using a sterile needle, performed for diagnostic purposes (to extract and analyze synovial fluid) or therapeutic purposes (to evacuate a fluid effusion or inject medications). It is a fundamental technique in rheumatology and orthopedics for the rapid evaluation of septic or microcrystalline arthritis.
• Arthrodesis — Surgical intervention aimed at the permanent fixation of a movable joint through artificial bone fusion, designed to restore skeletal stability and eliminate severe chronic pain. This procedure permanently blocks movement in the treated segment, serving as a final therapeutic solution for advanced joint destruction caused by arthrosis, major trauma, or congenital deformities.
