,Q1. A patient presents with acute onset of severe right hip pain and inability to bear weight after a fall.
Radiographs show a femoral neck fracture. Which of the following is the most significant risk factor for
osteonecrosis of the femoral head in this injury?
A. Displacement of the fracture
B. Patient age over 65 years
C. Delayed surgical fixation beyond 48 hours
D. Use of non-steroidal anti-inflammatory drugs
Correct Answer: A. Displacement of the fracture
Rationale: The blood supply to the femoral head primarily comes from the medial circumflex femoral artery, which
enters at the base of the femoral neck. Displaced fractures disrupt this blood supply, leading to a high risk of
osteonecrosis. Age, timing of surgery, and NSAIDs are less direct risk factors.
Why Wrong:
B - Age is a risk factor for fracture but not the primary determinant of osteonecrosis; displacement is more
critical.
C - Delayed fixation can increase infection risk but does not independently cause osteonecrosis; the initial
displacement matters more.
D - NSAIDs may impair bone healing but are not a direct cause of osteonecrosis in femoral neck fractures.

Q2. Which of the following best explains the biomechanical advantage of using a locked plate versus a
non-locked plate in the fixation of a comminuted distal femur fracture?
A. Locked plates allow compression across the fracture site, promoting primary bone healing.
B. Locked plates function as an internal fixator, providing angular stability independent of bone quality.
C. Locked plates require less soft tissue dissection, reducing infection risk.
D. Locked plates can be inserted percutaneously, minimizing blood loss.
Correct Answer: B. Locked plates function as an internal fixator, providing angular stability independent of
bone quality.
Rationale: Locked plates create a fixed-angle construct that resists axial and torsional forces, acting like an
external fixator placed internally. This is especially advantageous in osteoporotic bone or comminuted fractures
where screw purchase is poor. Compression is not the primary mechanism; locked plates typically span the fracture
without compression.
Why Wrong:
A - Locked plates are not designed for compression; they bridge the fracture, allowing secondary healing.
C - While locked plates can be used minimally invasively, the biomechanical advantage is angular stability,
not dissection reduction.
D - Percutaneous insertion is a technique, not a biomechanical property; non-locked plates can also be
inserted percutaneously.

Q3. A patient with a history of intravenous drug use presents with acute-onset severe low back pain, fever,
and difficulty walking. MRI shows L4-L5 discitis with epidural abscess. Blood cultures grow
methicillin-sensitive Staphylococcus aureus. Which of the following is the most appropriate initial
management?
A. Empiric vancomycin and surgical decompression within 24 hours
B. Cefazolin and urgent surgical debridement
C. Percutaneous disc aspiration and culture-guided antibiotics
D. Ceftriaxone and observation for 48 hours
Correct Answer: B. Cefazolin and urgent surgical debridement
Rationale: In this scenario, the presence of an epidural abscess with neurological symptoms (difficulty walking)
Page 3
, requires urgent surgical decompression to prevent permanent deficit. Cefazolin is appropriate for MSSA.
Vancomycin is reserved for MRSA or if the patient is allergic. Percutaneous aspiration is insufficient for an
abscess. Ceftriaxone is not first-line for MSSA osteomyelitis.
Why Wrong:
A - Vancomycin is not indicated for MSSA; cefazolin is preferred. Surgery is correct but vancomycin overtreatment.
C - Aspiration may help diagnose but does not treat the epidural abscess; surgical decompression is needed.
D - Ceftriaxone has poor bone penetration and is not first-line for MSSA; observation delays necessary surgery.

Q4. In a patient undergoing total knee arthroplasty, which of the following intraoperative findings is most
predictive of postoperative stiffness requiring manipulation under anesthesia?
A. Preoperative flexion contracture greater than 20 degrees
B. Intraoperative flexion gap larger than extension gap by 3 mm
C. Residual flexion contracture of 10 degrees after component placement
D. Patellar baja with medial tracking
Correct Answer: C. Residual flexion contracture of 10 degrees after component placement
Rationale: A residual flexion contracture after component placement indicates that the knee cannot fully extend,
leading to quadriceps weakness and a tendency for stiffness. This is a strong predictor of postoperative stiffness.
Preoperative contracture is a risk factor but not as directly predictive as intraoperative residual contracture. Gap
imbalance affects stability, not necessarily stiffness.
Why Wrong:
A - Preoperative contracture can be corrected intraoperatively; residual contracture after correction is more
predictive.
B - Flexion gap larger than extension gap can cause instability in flexion, not stiffness.
D - Patellar baja and tracking issues cause anterior knee pain or crepitus, not necessarily global stiffness.
Reference: Journal of Arthroplasty, 2025; Insall & Scott Surgery of the Knee, 6th Ed.
Q5. Which of the following MRI findings is most specific for a diagnosis of septic arthritis in a native knee
joint?
A. Joint effusion with synovial thickening
B. Bone marrow edema on both sides of the joint
C. Lobulated intra-articular mass with low T2 signal
D. Periarticular soft tissue abscess with sinus tract
Correct Answer: B. Bone marrow edema on both sides of the joint
Rationale: Bone marrow edema on both sides of the joint (reactive edema) is highly suggestive of septic arthritis,
as the infection causes inflammatory changes in the bone adjacent to the joint. Joint effusion and synovial
thickening are non-specific; they can occur in inflammatory arthritis. A lobulated mass with low T2 signal suggests
pigmented villonodular synovitis. A sinus tract is more typical of chronic osteomyelitis.
Why Wrong:
A - Effusion and synovial thickening are common in many arthritides, not specific for septic arthritis.
C - Lobulated low T2 mass is classic for PVNS, not infection.
D - Sinus tract is a feature of chronic osteomyelitis, not acute septic arthritis.

Q6. A patient with a history of breast cancer presents with new-onset right shoulder pain. Radiographs show
a lytic lesion in the proximal humerus with cortical destruction. Which of the following is the most
appropriate next step in management?
A. Bone scan to identify other metastases
B. CT-guided biopsy of the lesion
