Biomechanics and Orthopedics

Biomechanics involves the functions and structures of the musculoskeletal system and the movements of biological systems. Orthopedics involves the diagnosis and treatment of diseases, injuries, abnormalities, and functional disorders of the musculoskeletal system. Medical products that are tested include orthopedic implants, osteosynthetic implants, and prostheses, which support or replace physiological functions.
