structure, thing
abduction
movement away from the midline
acetabulum
hip socket in distal pelvic girdle for head of the femur
achondroplasia
a kon droh PLAY zha
congenital disorder of the growth of cartilage at the epiphyses of the long bones and skull, resulting in dwarfism
acromion process
highest point extending from the scapula
adduction
movement towards the midline
amphiarthroses
joints with limited range of motion (ROM)
Ex: vertebrae, female pubic bones during childbirth
ankyl/o
crookedness or stiffness
ankylosing spondylitis
chronic inflammatory disease of idiopathic origin, which causes a fusion of the spine
antrum
antr/o (also referred to as a sinus) a cavity or channel lined with a membrane
appendicular skeleton
append/o appendic/o shoulder bones, collarbones, pelvis bones, arms, and legs
arthrocentesis
surgical puncture of a joint to remove synovial fluid for analysis
arthrodesis
surgical binding or stabilization of a joint
arthrogram
x-ray of joint done after injection of contrast medium
arthrography
x-ray recording of a joint
arthroplasty
AR throh plas tee
general term meaning surgical repair of a joint
arthroscopy
ar THRAHS kuh pee
visual examination of a joint, accomplished by use of an arthroscope
arthrotomy
incision into a joint
articular cartilage
covers the ends of many bones and serves a protective function
axial skeleton
skull, rib cage, and spine
bone marrow
myel/o
bunion
fairly common, abnormal and painful enlargement and inflammation of the first metatarsophalangeal joint (base of the great toe)
bursa
burs/o (pl., bursae)
small, fluid-filled sac that allows easy movement of one part of a joint over another
calcium
calc/i calc/o
carpal
carp/o
wrist bones
carpal tunnel syndrome
compression injury that manifests itself as fluctuating pain, numbness, and paresthesias of the hand
In this condition, the median nerve is squeezed or constricted by a wrist ligament as it passes between that ligament and the bones and tendons of the wrist.
Numbness and burning pain have been reported in the fingers and hands, esp in the index and long fingers, sometimes extending all the way to the elbow.
cartilage
cartilag/o chondr/o
cervical
cervic/o neck bones (C1-C7)
chest
pector/o
chondroma
benign tumor of the cartilage, usually occurring in children and adolescents
chondrosarcoma
malignant tumor of the cartilage
occurs most frequently in adults
clavicle
clavicul/o
cleid/o
collar bone that connects the sternum to each scapula
closed reduction
no incision is necessary to align the bone
open reduction
proper alignment can occur only by making an incision
coccyx (KOCK sicks)
coccyg/o
coccygeal (kock sih JEE ul)
tailbone
Colles fracture
CALL-ees
break of the distal end of the radius at the epiphysis, often occurs when pt has attempted ot break his/her fall
comminuted fracture
the bone is crushed and/or shattered into many pieces
compact bone
hardest, densest layer just beneath the periosteum that contains blood vessels that deliver oxygen and nutrients to the bone while removing wastes such as CO2
complicated fracture
bone is broken and pierces an internal organ
compression fracture
the fractured area of bones collapses on itself
computed tomography (CT) scan
imaging technology that records transverse planes of the body for diagnostic purposes
condyle
condyl/o a rounded, knuckle-lick projection at the end of a bone that anchors ligaments and articulates with adjacent bones (aka near a joint)
contracture
chronic fixation of a joint in flexion caused by atrophy and shortening of muscle fibers after a long period of disuse
costals
ribs (12 pairs)
crest
a narrow, elongated elevation (such as the iliac crest)
cranial sinuses
frontal ethmoidal sphenoidal maxillary
debridement
removal of debris from a wound
depression
general term for an opening, groove, or hollow space in bone
DEXA scan
dual energy x-ray absorptiometry
a procedure that measures the density of bone at the hip and spine
an x-ray detector measures how well the x-rays penetrate the bone
dia-
complete, through
diaphysis
middle shaft of a long bone
diarthroses
joints with movement in all planes with full range of motion (ROM)
also called synovial joints
Ex: hips, knees, elbows, shoulders, wrists, and ankles
dorsalgia
upper back pain
dorsiflexion
raising the foot and pulling the toes toward the shin
dystrophy
abnormal development
eat, swallow
phag/o
elbow
olecran/o
electromyography (EMG)
procedure that records the strength of muscle contraction as a result of electrical stimulation
endo-, end-
within
epi-
above
epiphyses
ends of a long bone
epicondyle
epicondyl/o projection on the surface of the bone above the condyle
ethmoid
ethmoid/o bone that forms part of the nose, orbit, and floor of the cranium
eversion
turning outward
Ewing sarcoma
most common bone cancer in children
extension
the act of straightening, to increase the angle of a joint
fascia
fasci/o
plural: fasciae
tough fibrous covering of the muscles (and of some nerves and blood vessels)
external fixation
immobilizing bone(s) externally, like with a cast
CREF = closed reduction and external fixation
femur
femor/o
fibromyalgia
disorder characterized by musculoskeletal pain, fatigue, muscle stiffness and spasms, and sleep disturbances
