Navigate the New Structured Oral: Ditch Old Viva Worries
Key Takeaway
We review everything you need to understand about Navigate the New Structured Oral: Ditch Old Viva Worries. The new structured oral examination differs from traditional viva voce by employing blueprinting, structure, and careful standard setting for assessment. It provides a fair, consistent, valid, and reliable method, ensuring a representative sample of curriculum outcomes is tested. This modern approach prioritizes objective evaluation and candidate well-being, moving away from stressful, random questioning towards a more standardized and ethical assessment experience.
A 72-year-old female presents with a 6-month history of worsening left hip pain, significantly limiting her walking distance to 50 meters. She has failed a trial of physiotherapy and analgesia. Radiographs of the pelvis and left hip are provided below.
What are your findings and how would you manage this patient?
Candidate: "The radiograph shows signs of end-stage hip osteoarthritis with joint space narrowing, subchondral sclerosis, and osteophyte formation. Given her age, symptomatic severity, and failed conservative management, I would discuss a total hip replacement (THR) with the patient."
Candidates often jump straight to "I would offer a THR" without first describing the radiographic findings systematically or acknowledging the patient's functional status. Failing to mention clinical correlation or patient-specific risk assessment makes the answer appear robotic and clinically incomplete.
A structured response: 1. Describe the image: "The AP pelvis shows asymmetric narrowing of the left hip joint, subchondral sclerosis in the weight-bearing zones, inferomedial osteophytes, and subchondral cysts (acetabular side)." 2. Clinical correlation: "This is consistent with symptomatic advanced hip OA." 3. Management: "I would take a focused history regarding functional impact and fitness for surgery (co-morbidities), perform a clinical examination (Trendelenburg, ROM, neurovascular status), and consent for primary THR, emphasizing the risks including infection, dislocation, leg length discrepancy, and VTE."
The patient is booked for surgery. How do you plan the templating for this case, and what specific anatomical landmarks are you looking for?
Candidate: "I would use digital templating software. I'd look at the acetabular teardrop, the level of the femoral head center, and the trochanteric level to restore the center of rotation and leg length."
Failing to mention the magnification marker. If the radiograph is not calibrated using a radio-opaque marker (usually a ball of known size at the level of the greater trochanter), the templating is inaccurate and unsafe.
State: "First, I must verify the radiographic magnification using a calibrated ball marker. For the acetabulum, I aim to restore the anatomical hip center of rotation by referencing the teardrop and the Kohler’s line. For the femur, I reference the lesser trochanter as a reliable landmark for neck resection level to achieve appropriate leg length and offset restoration, ensuring I don't increase the femoral offset excessively to avoid tensioning the abductors too much."
