We offer several diagnostic tests and procedures at our Dartmouth-Hitchcock Medical Center location in Lebanon, NH, including:

  • Hyaluronic acid injection: An arthritis treatment that injects joints with synthetic joint fluid. This treatment may postpone the need for surgery at least temporarily and improve the quality of life for arthritis patients.
  • Joint aspiration: This test may be performed when there is unexplained pain, inflammation of a joint, or suspected infection in a joint. A sample of fluid is removed from the joint with a needle or in the operating room and examined in the laboratory. For more information, refer to the Joint Fluid Analysis topic on our Dartmouth-Hitchcock Healthwise® Health Encyclopedia website.
  • Methotrexate injections: This treatment partially suppresses the activity of the immune system and so decreases inflammation.
  • Musculoskeletal ultrasound: Musculoskeletal ultrasound is a noninvasive imaging test used to diagnose a variety of problems involving joints, tendons, ligaments and muscles. Ultrasound is a safe and painless procedure in which a small transducer (probe) is placed on the skin which sends sound waves into the tissues. The sound waves then bounce back and produce an image of the structure being examined.
  • Open muscle biopsy: The removal of a small piece of muscle tissue for examination, performed to differentiate between nerve and muscle disorders or to detect diseases including those of the connective tissue and blood vessels.
  • Synovial biopsy: A sample of tissue lining a joint is examined for bacterial or other infections and may suggest the presence of inflammatory conditions, such as autoimmune disorders.
  • Synovial fluid analysis: This treatment involves a battery of tests performed on joint fluid to help diagnose and treat joint-related abnormalities. For more information, refer to the Joint Fluid Analysis topic on our Dartmouth-Hitchcock Healthwise Health Encyclopedia website.
