chapter 15 Flashcards
exostosis
bony growth (benign) arising from the surface of bone
fracture
traumatic breaking of a bone
colles
fracture near the wrist at distal end of the radius
comminuted
bone is splintered and crushed into several pieces
compression
bone collapses or is compressed; occurs in vertebrae
Greenstick
bone is partially broken m; breaks on one surface and bends on another; ofteb occurring in forearm
impacted
one fragment is driven firmly into the other m; at the head of the femur or head of the humerus
osteogenic sarcoma ( osteosarcoma)
common malignant tumor arising from osteoblasts, found primarily in children and adolescents
osteomalacia
softening of bone, with inadequate amounts of mineral (calcium) in the bone
osteomyelitis
inflammation of the bone and bone marrow secondary to infection
osteoporosis
decease in bone density (mass); thinning and weakening of bone
talipes
congenital abnormality of the hindfoot (involving the talus)
joint ( articulation)
a coming together of two or more bones
suture joints
immovable joint
synovial joints
freely movable
joint capsule
surrounds the bones ina a synovial joint. IT is composed of fibrous tissue
ligaments
bone to bone
articular cartilage
a smooth, glistening white tissue that cover bones at the joint
meniscus
a crescent-shaped fibrocartilaginous structure that partly divides a joint cavity and acts as a protective cushion
bursae
closed sacs of synovial fluid lined with synovial membrane and are located near but not within a joint
tendon
muscle to bone
synovial cavity
space between bones at a synovial joint; contains synovial fluid produced by synovial membrane
synovial fluid
viscous (sticky) fluid with the synovial cavity. Synovial fluid is similar in viscosity to egg white; this accounts for the origin of the term
ankyl/o
stiff
arthr/o
joint
articul/o
joint
burs/o
bursa
chondr/o
cartilage
ligament/o
ligament
rheumat/o

synov/o
synovial membrane
ten/o
tendon
tendin/o
tendon
-desis
to bind, tie together
arthritis
inflammation of any joint
ankylosing spondylitis
chronic, progressive arthritis with stiffening of joints, primarily of the spine
gouty arthritis (gout)
inflammation and painful swelling of joints caused by excessive uric acid in the body
osteoarthritis (OA)
Progressive, degenerative joint disease with loss of articular cartilage and hypertrophy of bone (formation of osteophytes, or bone spurs) at articular surfaces.
rheumatoid arthritis (RA)
Chronic joint condition with inflammation and pain; caused by an autoimmune reaction against joint tissue, particularly the synovial membrane
bunion
enlargement of bone or tissue around the joint at the base of the big toe (metatarsophalangeal joint)
hallux
great toe
valgus
abnormal angulation of the toe
carpal tunnel syndrome (CTS)
Compression of the median nerve as it passes between the ligament and the bones and tendons of the wrist
dislocation
displacement of a bone from its joint
ganglion cyst
fluid-filled sac arising from joint capsules or tendons, typically in the hand
herniation of an intervertebral disk (disc)
abnormal protrusion of an intervertebral disk into the spinal canal or spinal nerves
lyme disease (Lyme arthritis)
disorder marked by arthritis, myalgia, and malaise; cause ia a bacterium carrried by tick
sprain
trauma to ligaments without rupture
systemic lupus erythematosis (SLE)
chronic inflammatory autoimmune disease involving joints, skin, kidneys, CNS, heart and lungs
fasci/o
fascia (forms sheaths enveloping muscles)
fibr/o
fibrous connective tissue
leiomy/o
smooth (visceral) muscle that lines the walls of internal organs
my/o
muscle
myocardi/o
heart muscle
myos/o
muscle
plant/o
sole of the foot
rhabdomy/o
skeletal (striated) muscle connected to the bones
sarc/o
muscle and flesh
-asthenia
lack of strength
muscular dystrophy
group of inherited diseases characterized by progressive weakness and degeneration of muscle fibers without involvement of the nervous system
polymyositis
chronic inflammatory myopathy
antinuclear antibody test (ANA)
Detects an antibody present in serum of patients with systemic lupus erythematosis (SLE) and other autoimmune diseases
erythrocyte sedimentation rate (ESR)
measures time it takes for erythrocytes to settle to the bottom of a test tube
rheumatoid factor test (RF)
serum is tested for the presence of an antibody found in patients with rheumatoid arthritis
serum calcium
measurement of calcium level in serum
serum creatine kinase (CK)
measurement of the enzyme creatine kinase in serum
uric acid test
measurement if uric acid in serum
arthrocentesis
surgical puncture to remove fluid from the joint space
bone scan
uptake of a radioactive substance is measured in done
diskography
x-ray examination of cervical and lumbar intervertebral disk after injection of contrast into nucleus pulposus (interior of the disk
ewing sarcoma
rare malignant tumor arising in bone; most often occurring in children
