Q

what happens during hematoma

A
  • clotted blood initiates a pro-inflammatory reaction
  • cell debris is cleared by phagocytes
  • necrotic bone (old bone) is removed by osteoclasts
20
Q

what happens during soft callus formation

A
  • new blood vessels appear
  • osteoblasts form new soft, sponges bone
  • fibrous tissue + cartilage is formed
  • fibrocartilaginous callus bridges both sites of the fracture
21
Q

what happens during bony callus formation

A
  • soft callus undergoes ossificaition
  • hardening of the callus starts at the sides and moves towards the centre of fracture
22
Q

what happens during bone remodelling

A
  • excess spongy bone is removed
  • spongy bone is converted into compact bone
23
Q

what causes bovine hyena disease

A

excessive vitamin A administration

24
Q

what happens in degenerative joint disease (DJD)

A

progressive and permanent long-term deterioration of the articular cartilage
- cartilage doesn’t have a blood supply so it’s impossible to help when lost

25
what is the name of the syndrome which causes respiratory distress in dogs
brachycephalic obstructive airway syndrome (BOAS)
26
with which gene is canine brachycephaly associated with
SPARC Related Modular Calcium Binding 2 (SMOC2) gene
27
what are morphological abnormalities in dogs with BOAS
- nostril stenosis (narrowing of openings) - elongated soft palate (extra tissue at roof of mouth) - caudal oversized turbinates (warms air going into lungs) - tongue not fitting shrunken head - misaligned teeth, inflamed mouth, excess tissue
28
what other disorders is brachycephaly linked to
- gastro-oesophageal reflux (contents of stomach moves to oesophagus) - can lead to oesophagitis, pharyngitis and laryngitis
29
what are clinical signs in dogs with BAOS
- laboured breathing - exercise / heat intolerance - difficulty eating - skinfold dermatitis - eye-bulb prolapse
30
what can brachycephalic cats have
- elongated soft palate - corneal ulcers - dental malformation - dermatological conditions due to inability to groom
31
what is spondylocostal dyostosis
- lethal congenital skeletal abnormality - hindquarters are reduced in size - associated with a mutation in Hes Family BHLH Transcription Factor 7 (HES7) gene - usually die if gene is activated
32
what is arachnomelia
- lethal congenital skeletal abnormality - thinning of all legs + severe angular deformities in distal part of forelegs - associated with mutation in molybdenum cofactor synthesis step 1 (MOCS1) gene in Simmental cattle - mutation in sulfite oxidase (SUOX) gene in Brown Swiss cattle
33
what is brachyspina
- lethal congenital skeletal abnormality - severe shortening of entire vertebral column + relatively long, slender legs - mutation in Fanconi complementation - group 1 (FANCI) gene
34
what is complex vertebral malformation
- lethal congenital skeletal abnormality - vertebral malformation, fixation of joint sin extended/flexed position - mutation in the Solute Carrier Family 35 Member A3 (SLC35A3) gene
35
what is cyclopia
- lethal congenital skeletal abnormality - incomplete division of embryonic prosencephalon, orbits of the eye in two cavities - associated with ingestion of cyclopamine in animals consuming Veratrum californicum, cyclopamine inhibits hedgehog signalling pathway
36
what is Ellis van Crevel syndrome
- non lethal skeletal abnormality - disproportionate dwarfism, shortened + twisted limbs -associated mutation is Ellis van Creveld syndrome 2 (EVC2) gene
37
what is Texel chondrodysplasia
- non lethal skeletal abnormality - disproportionate dwarfism, shortened neck + limbs + barrel-shaped chest - associated mutation in solute carrier family 13 (sodium/sulphate symporters), member 1 (SLC13A1) gene
38
what is syndactyly
- non lethal skeletal abnormality - single hoof like structure instead of paired claws - associated mutation in lipoprotein-receptor-related protein 4 ( LRP4) gene
39
what is a cleft palate
- non lethal skeletal abnormality - lack of fusion between structures forming a palate - many potential causes, including genetic factors, nutritional imbalances + infectious diseases
40
what is meningoencephalocele
- non lethal skeletal abnormality - cyst-like swelling in median part of skull cap, cerebrospinal fluid + brain tissues coexist - genetic factors, nutritional deficiencies + exposure to teratogenic agents during gestation
41
what is kyphosis
- non lethal skeletal abnormality - abnormal outward spinal curvature - diets lacking vitamin D
42
what is spinal dermoid sinus
- non lethal skeletal abnormality - vertebral + thoracic limb malformations
43
what are 5 risk factors for skeletal injuries/disorders
- obesity - breed - age - housing - management
44
when and what are some surgical treatments for skeletal disorders
- surgical treatment usually only done on high genetic merit animals - horse leg fractures are near impossible to treat - most common in companion animals - prosthetics are available - skin removal for BAOS
45
what are some non-surgical treatments
- laser therapy - spica splint - water walking
