Arm Injuries and Disorders

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

  • Tendinitis and bursitis
  • Sprains
  • Dislocations
  • Broken bones

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.
