10 - Skeletal Disorders Flashcards
Panosteitis is a common condition of
Long bones of young large breeds
Who is more likely to be affected by panosteitis
Male
Panosteitis presents how
Acute
Lameness panosteitis can persist
Several days to week s
What is the hisopathology of panosteitis
Increased osteoblastic and fibroblast activity in periosteum, endosteum and medullary cavity , fibrosis of the medullary cavity
Where should you palpate bones to test for panosteitis
Midshaft of the bones
Their is pain on palpation of what with panosteitis
Diaphysesal region of long bones
What is the early phase of panosteitis
Blurring and increased radio density of trabecular patterns, contrast between cortex and medullary canals less distinct
Middle phase of panosteitis
Patchy, sclerotic densities
Late phase of panosteitis
Medullary cavity becomes normal density , cortex may remain thicker
HOD is seen in
Young dogs, Great Danes, retrievers, and Weimaraner
Who is more likely to to have HOD
Males
Physical appearance of HOD
Gross swelling of distal metaphases of radius and ulna
HOD often have what involvement
Systemic
Immune mediated HOD is found in what breed
Weimaraner
Histopathology of HOD
Thickened periosteum with fibrosis , vascular Hypertrophy, zone of disrupted trabeculae in the metaphysics immediately adjacent and parallel to growth plate
Radio graphic signs of HOD
Radiolucency in the metaphysics parallel to the physics
HOD treatment
Start with immunosuppressive and steroids
Hypertrophic Osteopathy
Associated with thoracic or abdominal masses
HO is found where on legs
Firm swellings of distal limbs
HO is found in what dogs
Middle aged to older
