Hypertrophic Osteodystrophy

Question 1

What is hypertrophic osteodystrophy?

Answer 1

Supperative osteomyelitis of the metaphysis of long bone just below the growth plate?

Question 2

What are the risk factors of hypertrophic osteodystrophy?

Answer 2

Young about 3-5 months
Large breeds
Males > females

Question 3

What are the clinical signs/presentation of hypertrophic osteodystrophy?

Answer 3

Swelling of the metaphyseal region of long bones
Variable degrees of pain, inflammation & lameness
Systemic illness (Hyperthermia, anorexia, depression, diarrhea)

Question 4

What are the common locations for hypertrophic osteodystrophy?

Answer 4

Ulna
Tibia
Any long bone

Question 5

What diagnostics would you want to perform if hypertrophic osteodystrophy is suspected?

Answer 5

Radiographs
Blood culture

Question 6

What would you see on radiographs of early stages of hypertrophic osteodystrophy?

Answer 6

Soft tissue swelling adjacent to physis
Linear irregular lysis adjacent & parallel to physis
Physis preserved

Question 7

What would you see on radiographs of late stages of hypertrophic osteodystrophy?

Answer 7

Periosteal reaction become confluent with the cortex resulting in marked boney enlargement of the metaphysis

Question 8

What are the treatment options for hypertrophic osteodystrophy?

Answer 8

Analgesics
Balanced diet
Systemic support if systemically ill

Question 9

What is the prognosis of hypertrophic osteodystrophy?

Answer 9

Usually self limiting 7-10 days
Mild cases= good prognosis
