what is this fracture
open fracture
synarthrosis
no movement
amphiarthrosis
slightly movable (distal radio ulnar joint, symphysis pubis)
diarthrosis
freely movable
synovial
enclosed by joint capsule and lined with synovial membrane - freely movable
Joint definition: capsule
collagenous structure that surrounds the joint like a sleeve, protects cartilage while allowing movement of joint
Joint definition: synovial membrane
lines articular cavity, secretes synovial fluid
Joint definition: synovial fluid
serous fluid that lubricates the joint
Joint definition: bursa
fluid filled sack that develops in the spaces between tendons, ligaments, and bones
promotes ease of motion and prevents friction
Joint definition: meniscus
fibrocartilage structure between articular cartilage that provides stability and cushion
adherent to the synovial membrane
ligament
connects bone to bone
tendon
connects muscle to bone
tenosynovium
sheath surrounding a tendon that enhances movement or gliding of the tendon
sprain
injury of a ligament
strain
injury of a tendon or muscle
Ortho treatment: traction
sustained mechanical pull to improve a dislocation or fracture by gross realignment, preservation of nerve and blood supply (often used in femur fractures)
Surgical: arthrodesis
surgical fixation of a joint
Surgical: arthrotomy
surgical procedure to open and explore a joint
Surgical: external fixation
Surgical: internal fixation
metal screws and pins surgically inserted inside the bone to hold bone fragments in place to allow alignment and healing
Surgical: arthroplasty
joint replacement
Surgical: osteotomy
surgical procedure in which bones are cut and reoriented with the goal of improving extremity function - often used in correction of malunion of fractures
AROM
patient moves
PROM
patient relaxed and is moved by provider
arthritis
joint inflammation resulting in pain, swelling, stiffness, and limited movement
arthroscope
camera for a joint
arthrotomy
opening a joint capsule
genu
knee
hallux
big toe
insidious
onset out of nowhere
kyphosis
posterior convex curvature of the spine
lordosis
anterior convex curvature of the spine
mal-union or mal-alignment
when a broken bone heals in a poor alignment or deformed state
MOI
mechanism of injury
osteomyelitis
infection of the bone
osteophyte
outgrowth of the bone which forms around joints, deforming the joint and limiting their movements
osteoporosis
loss of bone density
pes
foot
planus
flattening of the arch of the foot
RICE
rest, ice, compression, elevation
scoliosis
lateral curvature of the spine
subluxation
partial dislocation
what is this an example of
valgus
what is this an example of
varus
contusion
direct impact or bruising (can be to muscle or bone)
