Musculoskeletal System QUIZ Flashcards
Degenerative Joint Disease (DJD) is caused by
1. Immune-mediated joint disease
2. All choices are possible causes of DJD
3. Trauma to joint
4. Hip dysplasia
- All choices are possible causes of DJD
Osteochondrosis Dissecans (OCD) is caused by:
1. All choices are possible triggers for OCD
2. Rapid growth of the puppy
3. Calcium:phosphorous imbalance in diet
4. Hereditary factors
- All choices are possible triggers for OCD
Masticatory Myositis
1. is idiopathic
2. is an immune-mediated disease
3. cannot be treated
4. is caused by an infection
- is an immune-mediated disease
- Confined to masticatory muscles of the face (permanet “lock jaw” can occur).
“Joint mice”
1. are protein precipitates within joint
2. are rodents with a drug addiction
3. are detached cartilage or bone fragments within joint
4. cause no clinical problems, but can be seen on radiograph
- are detached cartilage or bone fragments within joint.
- Seen in osteochondrosis dissecans (OCD)
T/F: Synovium is the cellular network within the joint that produces joint fluid.
True
T/F: Hip Dysplasia is arthritis inside the hip joint.
False.
Hip dysplasia is a joint malformation. It will most likely cause DJD of the hip as the animal ages due to abnormal weight bearing on the joint.
T/F: Panosteitis is an immune-mediated disease requiring life-long immunosuppressive therapy.
False.
It is an inflammatory disease of the medullary bone (idiopathic or possibly viral). Self limiting disease at 1yr old!
Feline Polymyositis requires life long supplements tho!
Name three possible clinical signs due to musculoskeletal disease (7)
Hint: Think of how bones/muscles are affected
- Muscle weakness
- Muscle tetany
- Invol muscle spasms/contractions (hypocalcemia) - Muscle pain
- Joint pain
- Joint swelling
- Lameness/abnormal gait
- Abnormal muscle function (i.e. chewing or swallowing)
Name three tests that might be done to evaluate for joint disease (6)
- Radiographs
- Blood serology
- CT scan
- Arthrocentesis for cytology
- and or - - Culture of joint fluid
Name three tests that might be done to evaluate for a myopathy (5)
- Blood serology
- Muscle biopsy
- Tensilon test
- Assess Pt strength, give inj, assess again. If improvement then Pt is positive. - Electromyography (EMG)
- Assess electric activity in muscles. - Blood Creatine Kinase (CK) level
Name two possible causes of Hip Dysplasia.
- Genetic
- Environmental
- Overweight
- Injury
- Overextension at young age
Name two clinical signs specific to Hip Dysplasia (be specific). (5)
Hint: Think of how it affects movement/stance of rear limbs
- Difficulty rising from lying position
- Reluctance to go upstairs/jump onto furniture
- “Bunny hop” gait
- Pain of extension of the hip joint
- Narrow and/or forward-based stance in rear legs (attempt to shift weight onto forelegs)
What might you tell the new owners of a Rottweiler puppy regarding Hip Dysplasia. (Both of puppy’s parents were graded “excellent” on OFA hip scores).
Prognosis? (4)
Prevention? (3)
Prognosis:
- Excellent hips of parents does not guarantee hip health in offspring.
- If hip dysplasia does develop there are medication and surgical treatments.
- Hip Dysplasia isn’t officially evaluated until pet is at least 2 years old.
- Dogs diagnosed with hip dysplasia should not be bred!
Prevention:
- Prevent rapid growth in large breed puppies (feed food especially for large breed puppies, no calcium supplements).
- Prevent trauma to hips of puppy.
- Keep puppy at ideal BCS (avoid puppy obesity).
