Clinical Information

  • ROTATOR CUFF TEAR ARTHROPATHY-. rapidly destructive shoulder joint and bone disease found mainly in elderly and predominantly in women. it is characterized by shoulder pain; joint instability; and the presence of crystalline calcium phosphates in the synovial fluid. it is associated with rotator cuff injuries.
  • CRYSTAL ARTHROPATHIES-. joint disorders that are characterized by accumulation of microcrystals in and around the joint including in the synovial fluid. they are classified according to the chemical nature of the crystals such as calcium pyrophosphate; basic calcium phosphates; and monosodium urate see uric acid.
  • ARTHROPATHY NEUROGENIC-. chronic progressive degeneration of the stress bearing portion of a joint with bizarre hypertrophic changes at the periphery. it is probably a complication of a variety of neurologic disorders particularly tabes dorsalis involving loss of sensation which leads to relaxation of supporting structures and chronic instability of the joint. dorland 27th ed

Information for Patients


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.
