XIII: Diseases of the musculoskeletal system and connective tissue

Group XIII of the ICD-10 classification pertains to diseases of the musculoskeletal system and connective tissue. These conditions typically involve issues with the body's structures that provide support, stability, and movement. These can include bones, muscles, joints, tendons, and ligaments. Common symptoms across these conditions may include pain, swelling, stiffness, decreased range of motion, and abnormalities in physical form or function. Causes can range widely from genetic predispositions, age-related wear and tear, injuries, infections, autoimmune disorders, to cancers. Diseases in this group often progress with time and can affect a person's mobility, dexterity, and overall physical capabilities. They represent a diverse range of conditions, from common issues like lower back pain and osteoarthritis to rare genetic disorders like Marfan syndrome and Ehlers-Danlos syndrome.
