The word 伤筋动骨 is formed by combining two verb-object phrases: 伤筋 (injuring tendons) and 动骨 (disturbing bones), where 伤 means "to injure", 筋 means "tendons", 动 means "to move" or "disturb", and 骨 means "bones", resulting in a literal description of physical damage to the body's connective tissues and skeletal structure.
