What are 6 types of Primary Bone Neoplasms?
1) Osteoma
2) Ossifying fibroma
3) Osteosarcoma
4) Chondroma
5) Chondrosarcoma
6) Multilobular tumor of bone
What type of Primary Bone Neoplasm is most common primary bone tumor in dogs and cats and in dogs, “Close to the knee and away from the elbow”?
Osteosarcoma
What type of Primary Bone Neoplasm accounts for ~10% of primary bone
tumors in dogs and involves flat bones (ribs, nasal turbinates, pelvis) more often than long bones?
Chondrosarcoma
What are 3 types of joints?
- Fibrous joints (synarthroses)
- Cartilaginous joints (amphiarthroses)
- Synovial joints (true joints or diarthroses):
Injury to articular cartilage results in fibrillation (fraying), eburnation or “Joint mice” formation is most common in what type of joint?
Synovial (diarthrodial) joints
What are 3 possible sequels from chronic joint injury?
1) Osteophyte formation
2) Pannus formation
3) Villous hypertrophy/ hyperplasia of synovial membrane
Which type of sequel chronic joint injury will lead to ankylosis (fixation) of the joint?
Pannus formation
What type of developmental joint disease is Characterized by abnormal growth and maturation of the articular cartilage and It is the most common cause of lameness in domestic animals, especially swine, horses, poultry and large breed dogs?
Osteochondrosis (Dyschondroplasia)
Dogs -> shoulder and elbow joints
Horses -> knee, hock, and fetlock joints
What is the diagnosis?
Osteochondrosis
What type of developmental joint disease is important in large breed dogs and characterized by lack of conformity between femoral head and
acetabulum -> subluxation-> DJD?
Hip Dysplasia
Identify which is Type 1 and Type 2
