Connective Tissue Disorders

Connective tissue is the material inside your body that supports many of its parts. It is the "cellular glue" that gives your tissues their shape and helps keep them strong. It also helps some of your tissues do their work. Cartilage and fat are examples of connective tissue.

There are over 200 disorders that impact connective tissue. Some, like cellulitis, are the result of an infection. Injuries can cause connective tissue disorders, such as scars. Others, such as Ehlers-Danlos syndrome, Marfan syndrome, and osteogenesis imperfecta, are genetic. Still others, like scleroderma, have no known cause. Each disorder has its own symptoms and needs different treatment.

Joint Disorders

A joint is where two or more bones come together, like the knee, hip, elbow, or shoulder. Joints can be damaged by many types of injuries or diseases, including

  • Arthritis - inflammation of a joint. It causes pain, stiffness, and swelling. Over time, the joint can become severely damaged.
  • Bursitis - inflammation of a fluid-filled sac that cushions the joint
  • Dislocations - injuries that force the ends of the bones out of position

Treatment of joint problems depends on the cause. If you have a sports injury, treatment often begins with the RICE (Rest, Ice, Compression, and Elevation) method to relieve pain, reduce swelling, and speed healing. Other possible treatments include pain relievers, keeping the injured area from moving, rehabilitation, and sometimes surgery. For arthritis, injuries, or other diseases, you may need joint replacement surgery to remove the damaged joint and put in a new one.
