CH 15 PATHOLOGY Flashcards
rare malignant tumor arising in bone; most often occurring in children
ewing sarcoma
bony growth arising from the surface of the bone - benign
exostosis
benign exostoses comprised of cartilage and bone usually found on metaphyses of long bones near the epiphyseal plates
osteochondromas
a swelling of metatarsophalangeal joint near the base of the big toe and is accompanied by the buildup of soft tissue and underlying bone at the distal medial aspect of the first metatarsal
bunion
traumatic breaking of bone
fracture
bone is broken but there is no open wound in the skin
simple/closed fracture
bone is broken and protrudes through an open wound in the skin
compound/open fracture
crackling sound produced when ends of bones rub each other or rub against roughened cartilage
crepitus
restoration of the bone to its normal position
reduction
manipulative reduction without a surgical incision
closed reduction
an incision is made for access to the fracture site
open reduction
solid mold of the body part, immobilizes injured bone so it can heal
cast
open reduction internal fixation
ORIF- often involves insertion of metal plates, screws, rods, and pins to stabilize the bone
malignant tumor arising from osteoblasts, found primarily in children and adolescents
osteogenic sarcoma (osteosarcoma)
malignant tumors from other parts of the body that metastasize to bones
metastatic bone lesions
softening of bone, with inadequate amounts of mineral calcium in the bone
osteomalacia
osteomalacia as a disease in infancy and childhood, uncommon
rickets
inflammation of the bone and bone marrow secondary to infection
osteomyelitis
walled-off area of infection that is difficult to penetrate with antibiotics
abcess
decrease in bone density (mass); thinning and weakening of the bone
osteoporosis
a condition in which bone mineral density is lower than normal
osteopenia
loss of bone mass due to osteoporosis produces posterior curvature of the spine in the thoracic region
khyphosis
congenital abnormality of the hindfoot involving the talus
talipes, congenital anomaly clubfoot
inflammation of any joint
arthritis
chronic, progressive arthritis with stiffening of joints, primarily of the spine
ankylosing spondylitis
inflammation and painful swelling in and around joints caused by the deposition of uric acid crystals
gouty arthritis / gout aka podagra
too much uric acid accumulates in the blood
hyperuricemia
progressive, degenerative joint disease with loss of articular cartilage and hypertrophy of bone (formation of osteophytes or bone spurs) at articular surfaces
osteoarthritis, or degenerative joint disease
chronic joint condition with inflammation and pain; caused by an autoimmune reaction against joint tissue, particularly the synovial membrane
rheumatoid arthritis
fibrous tissue forms and calcifies creating a pathologic union at the joint and preventing movement
bony ankylosis
enlargement of bone or tissue around the joint at the base of the big toe (metatarsophalangeal joint)
bunion
hallux valgus
great toe- another name for bunion
bunionectomy
removal of a bunion
compression of the median nerve as it passes between the transverse ligament, and bones and tendons of the wrist
carpal tunnel syndrome
displacement of a bone from its joint
dislocation, shoulder and hip are common
restoration of the bones to their normal position
reduction
a partial or incomplete dislocation
subluxation
fluid filled sac arising from joint capsules or tendons
ganglion cyst
abnormal protrusion of an intervertebral disc into the spinal canal or spinal nerves
herniation of an intervertebral disc- slipped disc
pain radiating down the leg and lower back pain when a disc protrudes into the lumber region
sciatica
removal of a portion of a protruding disc if it keeps slipping
microdiscectomy
chronic, recurrent disorder marked by severe arthritis, myalgia and malaise; cause is a bacterium carried by a tick
Lyme disease / Lyme arthritis
injury, often the result of trauma, involving overstretching of the ligaments around a joint
sprain- dont confuse with a strain
injury involving the overstretching of a muscle
strain
chronic inflammatory autoimmune disease involving joints, skin, kidneys, central nervous system, heart and lungs
systemic lupus erythematosus
connective tissue in tendons, ligaments, bones, and cartilage, specific protein
collagen
group of inherited diseases characterized by progressive weakness and degeneration of muscle fibers without involvement of the nervous system
muscular dystrophy
muscles appear to enlarge
pseudohypertrophy
most common form of muscular dystrophy
duchenne muscular dystrophy
chronic inflammatory myopathy, symmetric muscle weakness and pain often with rash - autoimmune disorder
polymyositis
detects an antibody often present in serum of patients with systemic lupus erythematosus SLE and other autoimmune diseases
antinuclear antibody test ANA
measures time it takes for erythrocytes to settle to the bottom of a test tube
erythrocyte sedimentation rate ESR
serum is tested for the presence of an antibody found in many patients with rheumatoid arthritis
rheumatoid factor test RF
measurement of calcium level in serum
serum calcium Ca
measurement of the enzyme creatine kinase in serum
serum creatine kinase CK
measurement of uric acid in serum
uric acid test
surgical puncture to remove fluid from a joint space
arthrocentisis
taking x-ray images after injection of contrast material into a joint
arthrography
surgical repair or replacement of a joint
arthroplasty
THR
total hip replacement
TKR
total knee replacement
small portion of bone removed to repair joint
resection arthroplasty
new tissue is placed between damaged surface of a joint such as elbow
interposition arthroplasty
an operation to replace a failing prosthetic joint
revision arthroplasty
visual examination of a joint with an arrthroscope which projects an image on a video monitor
arthroscopy
low energy xray absorption in bones of the spinal column, pelvis, and wrist is used to measure bone mass, also called dual energy xray absorptiometry
bone density test (bone densitometry) DEXA or DXA
uptake of a radioactive substance is measured in bone
bone scan
xray beam and computer show cross-sectional and other images of body tissues
computed tomography CT
xray examination of cervical or lumbar intervertebral disc after injection of contrast into nucleus pulposus (interior of the disc)
discography
recording of the electrical activity of muscle tissue
electromyography EMG
strong magnetic field and advanced computing technology are used to create high-resolution images of soft tissues inside the body
magnetic resonance imaging MRI
