Q

Dorsal flexion

A

if joints are in a state of overextension or dorsal flexion at rest flexion will result in an increase to the dorsal angle
- some joints such as the metacarpophalangeal and metatarsophalangeal joints can do this

Q

scoliosis

A

lateral deviation of the spine

24
Q

kyphosis

A

dorsal curvature (hump-backed)

25
lordosis
ventral curvature or deviation of the spine (horse is called sway-back)
26
spina bifida
absense of the dorsal portion of the vertebrae (mostly lumbar and sacral segments)
27
Physis
= physeal plate = metaphyseal growth plate
28
Growth cartilage =
growth plate (physis) + AEC (articular epiphyseal complex)
29
Chondrodystrophies
are disorders of bone growth as result of primary lesions to the growth cartilage
30
Osteochondrosis
focal failure of the endochondral ossification
31
osteopenia
don't have enough bone (nothing on quality of bone)
32
osteoporosis
don't have enough bone but the bone that is there is high quality
33
what is the rickets equivalent in adult animals
osteomalacia
34
Exostoses
benign outgrowth of cartilaginous tissue on bone
35
osteitis
inflammation of bone
36
periosteitis
inflammation of periosteum
37
osteomyelitis
Inflammation of the bone if the medullary cavity is involved
38
sequestrum
Bone that has become separated, during the process of necrosis, from surrounding tissue
39
Involucrum:
the dense rim of reactive tissue and surrounding a sequestered
40
isometric
increased tone but no change in the length of muscle
41
isotonic
increase in tone but with change in the length of muscle
42
Luxation
complete dislocation
43
Subluxation
partial dislocation
44
pannus
fibrovascular granulation tissue of bone
45
fibrous/bony ankylosis
(permanent fibrous tissue bridging across the joint space)
46
Chondromalacia
Palpable softening of the cartilage
47
Cartilage fibrillation
development of multiple vertical clefts
48
Subchondral bone eburnation
exposed subchondral bone becomes reinforced by new bone and constant rubbing causes it to appear dense, polished and ivory-like
49
periarticular osteophytes
multiple outgrowths of dense trabecular or compact bone resulting from endochondral ossification of foci of metaplastic cartilage
50
synovial chondromas
osteophytes
51
synovial osteochondromas
ostephytes
52
haemarthrosis
- Blood is phagocytosed by macrophages within joint capsule
53
arthrogryposis
hyperextension or hyperflexion of one or more limb joints
54
arthritis
inflammation of the synovium and other joint components
55
synovitis
inflammation restricted to the synovium
56
Tenosynovitis
= tendosynovitis or tendovaginitis) = inflammation of tendon sheath
