    3. First, both tumor and patient's bone marrow are destroyed with high-intensity radiation and chemotherapy.

    4. Then, healthy bone marrow stem cells are transfused into the recipient's blood to migrate to spongy bone where they multiply to form cancer-free red bone marrow.
  10. Allogenic bone marrow graft
    1. Uses healthy bone marrow cells from a compatible donor.

    2. Unless there is a perfect match, there is danger of rejection.

    Note: Allogenic means originating within another.
  11. Autologous bone marrow transplant

    Note: Autologous means originating within an individual.
  12. Orthotic
    Mechanical appliance, such as a leg brace or splint, that is specially designed to control, correct, or compensate for impaired limb function.
  13. Prosthesis
    Substitute for a diseased or missing body part, such as a lg that has been amputated.

    Plural: prostheses.
  14. Arthrodesis
    1. Surgical fusion or fixation of two bones to stiffen a joint, such as ankle, elbow, or shoulder.

    2. Procedure is performed to treat severe arthritis or damaged joint.

    3. Also known as surgical ankylosis.
  15. Arthrolysis
    Surgical loosening or release of an ankylosed joint.

    Note: Compare with arthrodesis.
  16. Arthroscopic surgery
    Minimally invasive procedure for treatment of the interior of a joint.

    Example: Torn cartilage can be removed with the use of an arthroscope and instruments inserted through small incisions around the knee.
  17. Bursectomy
    Surgical removal of a bursa.

    Example: Damaged bursa in shoulder joint often removed during rotator cuff surgery.
  18. Chondroplasty
    Surgical repair of a damaged cartilage.
  19. Synovectomy
    Surgical removal of a synovial membrane from a joint.

    2. One use of this procedure, which can be performed endoscopically, is to repair joint damage caused by rheumatoid arthritis.
  20. Arthroplasty
    1. Word parts mean 'surgical repair of a joint,' BUT term has come to mean the surgical placement of an artificial joint.

    • 2. These procedures are named for the involved joint and the amount of the joint that is replaced:
    • .....a. Total knee replacement
    • .....b. Partial knee replacement
    • .....c. Total hip replacement
    • .....d. Bone-conserving hip resurfacing
    • .....e. Revision surgery
  21. Total knee replacement
    1. Abbreviation: TKR

    2. All of the parts of the knee joint were replaced.

    3. Also known as total knee arthroplasty.
  22. Implant
    Common name for joint replacement prosthesis.
  23. Partial knee replacement
    1. Abbreviation: PKR

    2. Procedure in which only part of the knee is replaced.
  24. Total hip replacement
    1. Abbreviation: THR

    2. Performed to restore a damaged hip to full function.

    • 3. During surgery, a plastic lining is fitted into the acetabulum to restore a smooth surface.
    • .....The head of the femur is removed and replaced with a metal ball attaached to a metal shft that is fitted into the femur.
    • .....These smooth surfaces restore the function of the hip joint.

    4. Also known as a total hip arthroplasty.
  25. Bone-conserving hip resurfacing
    Alternative to removing the head of the femur.

    Function is restored to the hip by placing a metal cap over the head of the femur to allow it to move smoothly over a metal lining in the acetabulum.
  26. Revision surgery
    Replacement of a worn or failed joint implant.
  27. Percutaneous diskectomy
    1. Performed to treat a herniated intervetebral disk.

  29. Laminectomy
    1. Surgical removal of a lamina, or posterior portion, of a vertebra.

    2. To treat spinal stenosis by creating more room for the spinal cord to decompress as it passes through the area.
  30. Spinal fusion
    Technique to immobilize part of the spine by joining together (fusing) two or more vertebrae.

    Note: Fusion means 'to join together.'
  31. Craniectomy

    2, This procedure is performed to treat craniostenosis OR to relieve increased intracranial pressure due to swelling of the brain.
  32. Craniotomy
    1. Surgical incision or opening into the skull.

    2. This procedure is performed to gain access to the brain to remove a tumor, relieve intracranial pressure, or to obtain access for other surgical procedures.
  33. Osteoclasis
    Surgical fracture of a bone to correct a deformity.
  34. Cranioplasty
    1. Surgical repair of the skull.
  35. Ostectomy
    Surgical removal of bone.
  36. Osteoplasty
    Surgical repair of a bone or bones.
  37. Osteorrhaphy
    Surgical suturing, or wiring together, of bones.
  38. Osteotomy
    Surgical incision or sectioning of a bone.
  39. Periosteotomy
    A surgical incision THROUGH the periosteum TO the bone.
  40. Closed reduction
    1. Attempted realignmnet of the bone involved in fracture OR joint dislocation.

    2. The affected bone is returned to its normal anatomic alignment by manually applied forces and then is usually immobilized to maintain the realigned postion during healing.

    3. Also known as manipulation.
  41. Immobilization
    1. Act of holding, suturing, or fastening the bone in a fixed position with strapping or a cast.

    2. Also known as stabilization.
  42. Traction
    Pulling force exerted on a limb in a DISTAL direction in an effort to return the bone or joint to normal alignment.
  43. External fixation
    1. Fracture treatment procedure in which pins are placed through the soft tissue and bone so that an EXTERNAL appliance can be used to hold the pieces of bone firmly in place during healing.

    2. When healing is complete, the appliance IS removed.
  44. Internal fixation
    1. Fracture treatment in which a plate or pins are placed directly into the bone to hold the broken pieces in place.

    2. This form of fixation is NOT USUALLY removed after the fracture has healed.
