MSK Flashcards
Osteoartrhtisit is MC in:
M or W?
and what anatomical location
women
knee
tenderness of the entire joint, crepitus, instability, locking and deformity limiting both active and passive ROM due to pain or stiffness explains?
articular disease
point or focal tenderness in regions adjacent to articular strucutres and limits ROM explains?
extra-articular dz
which rarely causes swelling, instability or joints deformity:
-extra articular dz
or
-articular dz
extra articular dz
__ cervical
__ thoracic
___ lumbar
vertebrae are stacked on?
7 cervical
12 thoracic
5 lumbar
*stacked on sacrum and coccyx
bringing chin to chest is?
flexion of neck
looking up to the ceiling is
extension of neck
looking over the right and left shoulder is
rotation of neck
bringing right ear to shoulder and then same with the left is
lateral bending of neck
spine ROM
flexion–bend forward and touch toes
extension–bend as far back as poss
rotation–rotate side to side
lateral bending–bend side to side
list the articular strucutures (6)
- joint capsule
- articular cartilage
- synovium
- synovial fluid
- intra-articular ligaments
- juxta-articular bone
list extra articular strucs (8)
- periarticular ligaments
- tendons
- bursae
- muscle
- fascia
- bone
- nerve
- overlying skin
ropelike bundles of collagen fibrils that connect bone-bone
ligaments
collagen fibers that connect muscle-bone
tendons
collagen matrix overlying bony surfaces
cartilage
pouches of synovial fluid that cushion the movement of tendons and muscles over bone or other joint structures
bursae
synovial joints:
- move freely?
- what is bone covered by?
- what are bones separatd by?
- what lurbicates joint movement
- ex 5
moves freely
bones are covered by articular cartilage
bones are separated by synovial cavity
synovial membrane secreted synovial fluid that lubricates joint movement
EX: shoulder, knee, hip, tmj, interphalangeal joints of hand/foot
cartilaginous joints
- move freely?
- what is bone covered by?
- what lurbicates joint movement
- ex 2
slightly movable
bones sep by fibrocartilaginous discs
discs contain nucleus pulposus that cushions bony movement
EX: vertebral bodies of spine
fibrous joint
- movement?
- bones are separated by?
- ex
joints have no movement
-bones sep by fibrous tissue or catilage
ex: sutures of skull
spheroidal joint
- also called
- articular shape
- movement
- ex
ball and socket
articular shape=convex surface in concave cavity
-movement: wide range flexion, extension, abduction, adduction, rotation, circumduction
ex: shoulder, hip
Hinge joint
- articular shape
- movement
- ex
shape=flat, plantar
movement: motion is one plane…flexion and extension
ex: interphalangeal joints of hand and foot, elbow
condylar joint
- articular shape
- movement
- ex
shape= convex or concave
movenet: movement of two articulating surfaces.. not dissociable
ex: knee, TMJ
how does the knee joint move
its a condylar joint (type of synovial joint)
movement of two articulating surfaces— not dissociable
list the common or concerning symps
- low back pain
- neck pain
- joint pain
