Musculoskeletal Disorders Flashcards
Define: Aeitology
The cause, set of causes, or manner of causation of a disease or condition
Define: Pathogenesis
The mechanism by which the disease is caused
Define: Physiological
The study of changes of normal mechanical physical and biomechanical function
List 10 conditions which may reduce mobility
1- Hip dysplasia 2 - Osteoarthritis 3 - Elbow dysplasia 4 - Fractures 5 - Atrophy 6 - Toxicity 7 - Patella luxation 8 - Cruciate disease 9 - Herniated discs 10 - Poor confirmation
Define: Mobility
The ability and willingness to move
What parts make up musculo-skeletal system?
x6
muscles bones cartilage joints tendons ligaments
what is the purpose of the musculo-skeletal system?
Provide locomotion
supportive framework of the body
storage of minerals
What minerals are stored in the skeleton?
Calcium and phosphorus
What is the ratio range of Ca:Ph
1.5:1 - 2:1
What vitamin os meeded to ensure proper calcium absorption
Vitamin D - from the suuuuuuuuuun
Five functions of the skeleton
1 - Support the body 2 - System of levers for locomotion 3 - Protect soft parts of the body 4 - Mineral store 5 - Blood cell production within the bone marrow
define: Haemotopoieses
blood cell production from within bone marrow
Rickets - Pathophysiology
young animals - Vitamin D decificiency
- calcium decfiecincy
- phosphorus
- insufficient exposure to light
Rickets - clinical signs
- Lameness
- Limb bowing
- Swollen joints
- Green stocl fractures
Rickets - diagnosis
enlarged joints and growth plates widened and irregular
Rickets - treatment and nursing care
Correct dietary insufficincies
Analgesia
Limit exercise
Soft bedding
Hypertrophic Osteodystrophy (HOD) - Pathophysiology
Young rapidly growing dogs (large breed) Usually effects multiple limbs affects pataphysical region of long bones distal limbs failure of ossification
Hypertrophic Osteodystrophy (HOD) - Clinical signs
Acute pain debilitation severe lameness pyrexia swelling around growth plates anorexia inability to walk
Hypertrophic Osteodystrophy (HOD) - Diagnosis
Radiographs show necrotic band developing next to growth plate
Rough irregular apparence
Soft tissue swelling
Hypertrophic Osteodystrophy (HOD) - Treatment and nursing care
Clinical signs usually disappear as dog matures
Pain relief and feeding appropriate balanced diet
Hypertrophic Osteopahy (HO) - Pathophysiology
Perisoteal new bone formation along diaphysis of long bones
Does NOT involve joints
Hypertrophic Osteopahy (HO) - Clinical signs
Bilateral soft tissues swelling
Lameness
Reluctance to move
pain +++
Hypertrophic Osteopahy (HO) - diagnosis
radiographs of affected limbs
