comminuted femoral fracture. Which imaging modality is most useful in pre‐surgical
planning?
A) Radiography
B) Ultrasound
C) Computed tomography
D) Magnetic resonance imaging
Answer: C
Explanation: CT provides detailed cross‐sectional images that are crucial for planning the
surgical repair of complex fractures.

fixation technique is most appropriate for minimizing additional soft tissue damage?
A) Internal fixation with plating
B) External coaptation
C) Intramedullary pinning
D) External skeletal fixation
Answer: B
Explanation: External coaptation is less invasive and minimizes additional trauma to already
swollen soft tissues.
Question 3: In a small animal case with a distal femoral fracture and joint involvement,
which fixation method is indicated?
A) External skeletal fixation
B) Internal fixation with bone plate
C) Intramedullary pinning
D) Casting alone
Answer: B
Explanation: Internal fixation with a bone plate allows precise reduction and stabilization of
fractures involving the joint surface.
Question 4: A patient presents with a suspected non-union of a previously fractured tibia.
What is the most likely contributing factor?
A) Overly rigid fixation
B) Inadequate blood supply
C) Excessive immobilization
D) Early mobilization
Answer: B
Explanation: Inadequate blood supply can impede healing, leading to non-union of fractures.
,Question 5: A case of osteomyelitis following fracture repair requires revision surgery.
What is the most critical step during the revision procedure?
A) Immediate internal fixation
B) Thorough debridement of infected tissue
C) Rapid wound closure
D) Use of high-dose steroids
Answer: B
Explanation: Debridement of all infected and necrotic tissue is essential to control infection and
promote healing.
Question 6: During arthroscopy in a small animal with chronic joint inflammation, what is
the primary advantage of the procedure?
A) Larger incision for direct visualization
B) Minimally invasive evaluation and treatment
C) Better aesthetic outcome
D) Increased risk of infection
Answer: B
Explanation: Arthroscopy is minimally invasive, providing effective visualization and treatment
of joint conditions with reduced morbidity.
Question 7: A dog undergoing arthrotomy for joint infection is at risk for post-operative
complications. Which complication is most common?
A) Implant failure
B) Persistent infection
C) Nerve injury
D) Excessive bleeding
Answer: B
Explanation: Persistent infection is a significant risk following joint surgery, especially when
infection is present pre-operatively.
Question 8: In a prosthetic joint replacement case, which factor is most critical to ensure
long-term success?
A) Choice of implant material
B) Duration of anesthesia
C) Owner compliance
D) Use of external coaptation post-surgery
Answer: A
Explanation: The implant material must be biocompatible and durable to reduce complications
and ensure longevity.
Question 9: A small animal patient with an abdominal mass requires soft tissue surgery.
What is the first step in preparing for resection?
A) Initiating antibiotic therapy
B) Complete pre-operative staging
C) Immediate surgery
D) Post-operative pain management planning
,Answer: B
Explanation: Complete pre-operative staging ensures that all factors, including metastasis, are
evaluated before proceeding with surgery.
Question 10: In thoracic surgery for a dog with lung lobe torsion, which surgical approach
is most commonly used?
A) Median sternotomy
B) Lateral thoracotomy
C) Paramedian incision
D) Ventral midline approach
Answer: B
Explanation: Lateral thoracotomy provides optimal access to the lung lobes and is the standard
approach for lung lobe torsion.
Question 11: A cat is diagnosed with a complex joint infection. Which diagnostic procedure
is essential to confirm the causative organism?
A) Joint fluid cytology and culture
B) Plain radiography
C) MRI scan
D) Ultrasound examination
Answer: A
Explanation: Analyzing joint fluid through cytology and culture helps identify the pathogen and
guide appropriate antibiotic therapy.
Question 12: A small animal presents with a mid-diaphyseal fracture of the humerus.
Which fixation method minimizes the risk of iatrogenic damage to surrounding soft tissue?
A) Open reduction with internal fixation
B) Closed reduction and external coaptation
C) Intramedullary pinning
D) External skeletal fixation
Answer: D
Explanation: External skeletal fixation allows stabilization while reducing the risk of additional
soft tissue trauma compared to open reduction.
Question 13: In managing a fracture with delayed union, what is a common adjunctive
treatment to stimulate healing?
A) Increased immobilization
B) Electrical stimulation
C) Immediate weight bearing
D) High-dose corticosteroids
Answer: B
Explanation: Electrical stimulation can enhance bone healing in cases of delayed union by
promoting cellular activity.
Question 14: A small animal patient with a comminuted pelvic fracture requires
stabilization. Which technique is most suitable?
, A) External coaptation only
B) Internal fixation with plating
C) Combination of internal and external fixation
D) Closed reduction with casting
Answer: C
Explanation: Comminuted pelvic fractures often benefit from a combined approach to provide
adequate stabilization and alignment.
Question 15: For a dog with a suspected ligament injury causing joint instability, what is
the recommended diagnostic method?
A) Arthroscopy
B) Stress radiography
C) Ultrasound
D) CT scan
Answer: B
Explanation: Stress radiography is used to evaluate joint stability and confirm ligament injuries.
Question 16: In managing a fracture-related infection, which of the following is essential in
the treatment protocol?
A) Sole reliance on oral antibiotics
B) Surgical debridement combined with antibiotic therapy
C) Extended immobilization without debridement
D) Use of analgesics only
Answer: B
Explanation: Combining surgical debridement with targeted antibiotic therapy is key to
eradicating infection in fracture cases.
Question 17: A 5-year-old dog presents with a spiral fracture of the tibia. What is the
advantage of using intramedullary pinning in this case?
A) Provides external stabilization
B) Minimizes surgical time and soft tissue damage
C) Allows immediate weight bearing
D) Eliminates the need for post-operative care
Answer: B
Explanation: Intramedullary pinning is minimally invasive, leading to less soft tissue disruption
and a quicker procedure.
Question 18: In a case of joint surgery for osteoarthritis, which surgical intervention is
most appropriate for severe cases?
A) Arthroscopy for debridement
B) Total joint replacement
C) Conservative management with medications
D) Partial joint resurfacing
Answer: B
Explanation: In severe osteoarthritis, total joint replacement can offer significant improvement
when other measures fail.
