#joint fusion

• 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.
• Ankylopoiesis — A progressive pathological process of formation, development, or induction of ankylosis within a joint; the biological mechanism through which synovial tissue and articular cartilage are gradually replaced by fibrous or bony tissue, leading to complete immobilization and stiffening of the affected joint structures.
• 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.
• 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.
