Flashcards in Chap 15, Clinical Procedures Deck (11)
Surgical puncture to remove fluid from the joint space. Synovial fluid is removed for analysis.
Taking x-ray images after injection of contrast material into a joint.
Surgical repair or replacement of a joint (with prostheses); total hip replacement (THR) and total knee replacement (TKR) are examples. Other examples of arthroplasties are resection arthroplasty (small portion of a bone is removed to repair the joint; acromioclavicular joint is a common location), interposition arthroplasty (new tissue taken from another place is placed between damaged surface of elbow joint, and revision arthroplasty (an operation to replace a failing prosthetic joint).
Visual examination of a joint with an arthroscope and television camera. An orthopedist passes small surgical instruments into a joint (knee, shoulder, ankle, wrist, hip) to evaluate and/or remove and repair damaged tissue.
bone density test (bone densitometry)
Low-energy x-ray absorption in bones of the spinal column, pelvis, and wrist is used to measure bone mass. An x-ray detector measures how well x-rays penetrate through bones. Areas of decreased density indicate osteopenia and osteoporosis. Also called dual-energy x-ray absorptiometry (DEXA or DXA).
Uptake of a radioactive substance is measured in bone. A nuclear medicine physician uses a special scanning device to detect areas of increased uptake (tumors, infection, inflammation, stress fractures).
computed tomography (CT)
X-ray beam and computer provide cross-sectional and other images. CT scans identify bone abnormalities, and musculo-skeletal trauma.
X-ray examination of cervical or lumbar intervertebral disk after injection of contrast into nucleus pulposus (interior of the disk).
Recording the strength of muscle contraction as a result of electrical stimulation.
magnetic resonance imaging (MRI)
Magnetic field creates images of soft tissue. MRI shows soft tissue conditions in greater detail than that achieved with CT.
