Ontology: Arm Injuries (C0003794)

Definition (MEDLINEPLUS)

Of the 206 bones in your body, 3 of them are in your arm; the humerus, radius and ulna. Your arms are also made up of muscles, joints, tendons and other connective tissue. Injuries to any of these parts of the arm can occur during sports, a fall or an accident.

Types of arm injuries include

Some nerve problems, arthritis, or cancers can affect the entire arm and cause pain, spasms, swelling and trouble moving. You may also have problems or injure specific parts of your arm, such as your hand, wrist, elbow or shoulder.

Definition (MSH) General or unspecified injuries involving the arm.

Ontology: Soft Tissue Injuries (C0037578)

Definition (MSH) Injuries of tissue other than bone. The concept is usually general and does not customarily refer to internal organs or viscera. It is meaningful with reference to regions or organs where soft tissue (muscle, fat, skin) should be differentiated from bones or bone tissue, as "soft tissue injuries of the hand".
