articular separation (patella)

19
Q

Arthrocentesis

A

joint tap, removal of fluid from joint by sterile means

20
Q

Bursitis

A

inflammation of bursa

21
Q

FHO

A

Femoral Head Osteotomy

muscles acting as hip joint after femoral head removed

22
Q

False Joint

A

?? surgical procedure

23
Q

Flexion

A

decreases angle

Synovial joint movement

24
Q

Extension

A

increases angle

Synovial joint movement

25
Adduction
toward median | Synovial joint movement
26
Abduction
away from median | Synovial joint movement
27
Rotation
twist on axis | Synovial joint movement
28
Circumduction
distal end moves in circle | Synovial joint movement
29
Supinate
move palm side up | Synovial joint movement
30
Pronate
move palm side down | Synovial joint movement
31
Universal
all movements | Synovial joint movement
32
Hinge synovial joint
joint swivels around another only flexion and extension possible (elbow and alantooccpital- yes movement)
33
Gliding synovial joint
rocking motion joint surfaces flat; flexion and extension mainly with minimal abduction and adduction ex carpus and tarsus
34
Pivot synovial joint
one joint rotates or pivots on another; only rotation | ex - atlantoaxial joint (no movement)
35
Ball and socket synovial joint
most extensive movement (universal as allow flexion, extension, adduction, abduction, circumduction, and rotation ex - hip and shoulder
