Musculoskeletal Diseases Flashcards
1
Q
Skeletal Muscle
A
- Striated and voluntary muscle
- Actin and myosin fibers in the sarcomere move to contract muscle
- Acetylcholine Neurotransmitter
- Calcium required for muscle contraction
2
Q
Legg-Calve-Perthes Disease
A
- Avascular necrosis of the femoral head
- Young, small breed dog
- Lameness of hind limb, pain on extension of coxofemoral
- Tx: FHO excision
3
Q
Osteochondrosis Dissecans (OCD)
A
- Cartilage problem
- Occurs at articular surface
- Common areas: shoulder, stifle, hock, and elbow
- Young, large breed dogs
- Lameness
4
Q
Panosteitis
A
- Young, large breed dogs, german shepherds
- shirting leg lameness
- increased density in the medullary cavity of long bones
- pain on palpation of long bones
- self-limiting
5
Q
Elbow Dysplasia
A
- Incongruency of elbow joint
- Young, large breed, rapidly growing dogs
- Tx: surgery
6
Q
Rheumatoid Arthritis
A
- Immune complexes are deposited in joints
- Older, small breed dogs
- lameness, joint swelling
- Type III immune hypersensitivity
7
Q
Hip Luxations
A
- Trauma caused
- Joint capsules and round ligament must tear in order for femur to luxate
- Non-weight bearing
- Closed/open reduction
- Ehmer Sling
8
Q
Masticatory Muscle Myositis
A
- Mouth muscles become swollen and painful
- Immune-mediated disease
- End stage: muscles fibrose and mouth cannot open
9
Q
Osteosarcoma
A
- Older, large breed dogs
- Proximal: humerus, tibia
- Distal: femur, radius
- “Away from the elbow, close to the knee”
- Lameness, pain
- Thoracic rads; early metastasis common
