Orthopedics

From WikiMD's Wellness Encyclopedia

Orthopedics (or orthopaedics) is a branch of medicine that focuses on the care of the musculoskeletal system. This includes the bones, joints, ligaments, tendons, and muscles that allow you to move, work, and be active.

History[edit | edit source]

The term "orthopedics" comes from the Greek words "orthos," which means straight, and "paideia," which means raising children. Originally, the field focused on the care of children with spine and limb deformities. Today, orthopedic physicians treat everyone, regardless of age, for a variety of conditions such as fractures and dislocations, tendon injuries, pulled muscles, and bursitis.

Diagnosis and Treatment[edit | edit source]

Orthopedic physicians use both surgical and nonsurgical means to treat musculoskeletal trauma, spine diseases, sports injuries, degenerative diseases, infections, tumors, and congenital disorders. They have the expertise to diagnose your condition, identify the type of treatment you need, and provide the necessary care.

Subspecialties[edit | edit source]

There are several subspecialties within orthopedics, including:

Education and Training[edit | edit source]

To become an orthopedic physician, one must complete four years of medical school, followed by a five-year residency program. Some physicians also choose to specialize further by completing a fellowship program in one of the subspecialties.
