Orthopedics is the healthcare specialty that deals with most skeletal disorders and associated muscle, joint, and ligament conditions. An orthopedist is a physician who is specially trained to diagnose and treat skeletal system disorders. Some orthopedists specialize in certain areas of the body, such as hand, ankle, and foot injuries. An orthopedic surgeon is a specially trained physician who medically, surgically, and physically treats musculoskeletal disorders. Podiatry is the branch of medicine that deals with the diagnosis, treatment, and prevention of foot disorders. A podiatrist is a physician who specializes in treating the foot and ankle.
Rheumatology is a specialty that deals with disorders of connective tissue, including bone and cartilage. Rheumatology also deals with many diseases that are classified as autoimmune disorders. A rheumatologist is a physician who specializes in internal medicine and rheumatology. A rheumatologist treats patients with diseases of joints, muscles, bones, and tendons.
Musculoskeletal system diseases and disorders are common in an ambulatory care facility. When they are not seen in the orthopedic department, patients with musculoskeletal concerns are seen in primary care and urgent care settings.

Musculoskeletal System

The musculoskeletal system (MS) consists of bones, joints, muscles, and supportive connective tissues (cartilage, tendons, and ligaments). The musculoskeletal system is responsible for the following functions:

• Body movement
• Protection, support, and framework for the organ systems of the body
• Storage for important minerals such as calcium and phosphorus
• Continually forming new blood cells by the process of hematopoiesis, which occurs in the red bone marrow inside some bones. Red blood cells, white blood cells, and platelets are all made in the bone marrow.

In this chapter, the discussion of the anatomy, physiology, and pathology of the musculoskeletal system is divided into the skeletal system and the muscular system.
