4 Skeletal disorders Flashcards
Chondrosdystrophy
Abnormalities in size and shape of bone
Lesion in growth plate/articular-epiphysis complex
Osteochondrosis
degenerative process of cartilage
Involves growth plate or AE complex
Large dog breeds
Osteochondrosis dissecans
Dysplasia at AE complex
Can become degenerative joint disease
Osteoporosis
Bone resorption is greater than bone formation
Failure of mineralization with subsequent bone deformities and fracture in GROWING skeleton
Rickets
Failure of mineralization with subsequent bone deformities and fracture in adult skeleton
Osteomalacia
Fibrous osteodystrophy
Increased osteoclastic resorption of bone and replacement of fibrous tissue
Causes of fibrous osteodystrophy
Hyperparathyroidism
Primary: Rare
Secondary: Nutritional or Renal
What type of diet can cause nutritional osteodystrophy
low in Calcium or high in Phosphorus
Both increase parathyroid hormone causing bone resorption
Infectious necrosis of bone
Osteomyelitis
Non-infectious necrosis of bone
Hypertrophic osteoystropy
Primary and secondary neoplasia
Primary: Osteosarcoma
Secondary: Metastacic
Hypsodontic Teeth
Grow throughout life
horse
Brachydontic teeth
Do not grow throughout life
Root not covered in enamel
Dog
Maloclussion
failure of upper and lower teeth to interdigitate properly
