Cards

Term
ankylosis
Definition
Stiffening and immobility of a joint as a result of disease, trauma, surgery, or abnormal bone fusion
Term
carpal tunnel syndrome (CTS)
Definition
Painful condition resulting from compression of the median nerve within the carpal tunnel (wrist canal through which the flexor tendons and the median nerve pass)
Term

Definition
Lameness, limping
Term
contracture
Definition
Fibrosis of connective tissue in the skin, fascia, muscle, or joint capsule that prevents normal mobility of the related tissue or joint
Term
crepitation
Definition
Dry, grating sound or sensation caused by bone ends rubbing together, indicating a fracture or joint destruction
Term
electromyography
Definition
Use of electrical stimulation to record the strength of muscle contraction
Term
exacerbation
Definition
Increase in severity of a disease or any of its symptoms
Term
ganglion cyst
Definition
tumor of tendon sheath or joint capsule, commonly found in the wrist
Term
hemarthrosis
Definition
Effusion of blood into a joint cavity
Term
hypotonia
Definition
Loss of muscular tone or a diminished resistance to passive stretching
Term
multiple myeloma
Definition
Primary malignant tumor that infiltrates the bone and red bone marrow
Term
osteophyte
Definition
Bony outgrowth that occasionally develops on the vertebra and may exert pressure on the spinal cord also called bone spur.
Term
phantom limb
Definition
Perceived sensation, following amputation of a limb, that the limb still exists
Term

Definition
Replacement of a missing part by an artificial substitute, such as an artificial extremity
Term

Definition
Form of osteomalacia in children caused by vitamin D deficiency; also called rachitis

Definition
Fragment of necrosed bone that has become separated from surrounding tissue
Term
spondylolisthesis
Definition
Any slipping (subluxation) of a vertebra from its normal position in relationship to the one beneath it
Term
spondylosis
Definition
Degeneration of the cervical, thoracic, and lumbar vertebrae and related tissues may cause pressure on nerve roots with subsequent pain or paresthesia in the extremities.
Term
sprain
Definition
Tearing of ligament tissue that may be slight, moderate, or complete
Term
strain
Definition
To exert physical force in a manner that may result in injury, usually muscular
Term
subluxation
Definition
Partial or incomplete dislocation
Term
talipes equinovarus
Definition
Congenital deformity of one or both feet in which the foot is pulled downward and laterally to the side; also called clubfoot
Term
arthrography
Definition
Series of radiographs taken after injection of contrast material into a joint cavity, especially the knee or shoulder, to outline the contour of the joint
Term
bone density tests
Definition
Radiographic procedures that use low-energy x-ray absorption to measure bone mineral density (BMD). They are used to determine if demineralization from osteoporosis has occurred. The areas of decreased density indicate osteopenia and osteoporosis. There are two types of bone density tests, dual-energy x-ray absorptiometry (DEXA or DXA) scan, also known as bone densitometry, and computed tomography (CT).
Term
computed tomography (CT)
Definition
maging technique that uses an x-ray beam and a computer to make a series of cross-sectional images of a body part, which together make up a three-dimensional view of the area scanned; formerly called computerized axial tomography (CAT)
Term
discography
Definition
Radiological examination of the intervertebral disk structures by injecting a contrast medium
Term
lumbosacral spinal radiography
Definition
Radiography of the five lumbar vertebrae and the fused sacral vertebrae, including anteroposterior, lateral, and oblique views of the lower spine. It is used to identify or differentiate traumatic fractures, spondylosis, spondylolisthesis, and metastatic tumor.
Term
myelography
Definition
Radiography of the spinal cord after injection of a contrast medium to identify and study spinal distortions caused by tumors, cysts, herniated intervertebral disks, or other lesions
Term
scintigraphy
Definition
Nuclear medicine procedure that visualizes various tissues and organs after administration of a radionuclide. After absorption of the radioactive substance, a scanner detects the radioactive tracer and makes a photographic recording (scintigram) of radionuclide distribution using a gamma camera to detect areas of uptake, called hotspots.
Term
bone scintigraphy
Definition
Scintigraphy procedure in which radionuclide is injected intravenously and taken up into the bone. Used to detect bone disorders, especially arthritis, fractures, osteomyelitis, bone cancers, or areas of bony metastases. Areas of increased uptake (hot spots) are abnormal and may be infection or cancer.
Term
Closed reduction
Definition
Reduction procedure where fractured bones are realigned by manipulation rather than surgery.
Term
Open Reduction
Definition
Reduction procedure that treats bone fractures by placing the bones in their proper position using surgery. In reduction of a complicated fracture, an incision is made at the fracture site and the fracture is reduced. Often internal fixation devices such as nails, screws, or plates are required to fix the fracture fragments in their correct anatomical position.
Term
casting
Definition
Application of a solid, stiff dressing formed with plaster of Paris or other material to a body part to immobilize it during the healing process
Term
splinting
Definition
Application of an orthopedic device to an injured body part for immobilization, stabilization, and protection during the healing process
Term
traction
Definition
Use of weights and pulleys to align or immobilize a fracture and facilitate the healing process
Term
amputation
Definition
Partial or complete removal of an extremity due to trauma or circulatory disease
Term
arthrocentesis
Definition
Puncture of a joint space using a needle to remove accumulated fluid
Term
arthroclasia
Definition
Surgical breaking of an ankylosed joint to provide movement
Term
arthroclasia
Definition
Surgical breaking of an ankylosed joint to provide movement
Term
arthroscopy
Definition
Visual examination of the interior of a joint and its structures using a thin, flexible fiberoptic scope called an arthroscope that contains a magnifying lens, fiberoptic light, and miniature camera that projects images on a monitor
Term
bone grafting
Definition
Implanting or transplanting bone tissue from another part of the body or from another person to serve as replacement for damaged or missing bone tissue
Term
