Orthopedics focuses on preventing, diagnosing, treating, and rehabilitation of the diseases/conditions affecting the musculoskeletal system. 

The skeletal system has 5 main functions.

• 1: Movement: the skeleton allows movement of the body as a whole and its individual parts. The bones act as levers and also form joints that allow muscles to pull on them and produce joint movements.

• 2: Support and protection – the bones of the skeleton provide support for the body and also protect the organs found within it. 

• 3: Production of blood cells – certain bones in the skeleton contain red bone marrow and the bone marrow produces red blood cells, white blood cells, and platelets.

• 4: Storage of minerals – the bones themselves are made of minerals and act as a mineral store for calcium and phosphorous.

• 5: Attachment of muscles – the bones of the skeleton provide surfaces for the attachment of muscles. This is why bones are often irregular shapes and have bony points and grooves to provide attachment points.
