1-2. CAUSES OF DEVIATIONS FROM NORMAL MUSCULOSKELETAL FUNCTIONING
Disease, defects, and trauma are the major causes of musculoskeletal system malfunction. Diseases such as arthritis, osteoporosis (imbalance between bone formation and reabsorption), and tumors interfere with proper musculoskeletal functioning. Other defects such as cysts and congenital problems can cause malfunctioning. Trauma to the body such as fractures, sprains, dislocations, subluxations, and strains also cause musculoskeletal system dysfunction.
