Deformity refers to any abnormal or irregular shape, form, or appearance in a person's body. It can be caused by various factors such as genetic disorders, injuries, birth defects, or diseases that affect bones, muscles, and other tissues. Deformities can range from mild to severe, and may impact the functioning of the affected body part or parts. Some common examples of deformity include scoliosis (a sideways curvature of the spine), clubfoot (a condition where one foot is turned inward), and cleft lip/palate (an opening in the roof of the mouth). Treatment for deformities may involve surgery, physical therapy, or other interventions to help improve function and appearance.
