4. Regarding obstetric brachial plexus injuries, which of the following is not typically associated with Erb’s palsy?

Forearm pronation
Increased likelihood of skin infection
Shoulder adduction
Anterior shoulder dislocation

(Question 4 of 10)

5. Which of the following is the most sensitive clinical sign for detection of developmental dysplasia of the hip (DDH) in a baby aged 6 months?

Galeazzi test
Barlow’s test
Asymmetric skin folds in the thighs
Ortolani’s test
Limited hip abduction in flexion

(Question 5 of 10)

6. A 25 years old patient is admitted with a forearm radius and ulna shaft fractures. You proceed with an open reduction and internal fixation. Regarding the implant used, which of the following statements is CORRECT:

The bending rigidity of plate is proportional to the second power of it’s thickness
Compared to titanium, the elastic modulus of stainless steel is closer to the cortical bone.
The pullout strength of screw is proportional to the core diameter of the screws
Maximum efficiency of plate is achieved when it’s applied to the tension side of the fracture.
In transverse fractures, a convex pre-bending of the plate is required to help achieving compression

7. While performing a total knee replacement for a knee with valgus deformity, to balance the coronal plane, which of the following statement is CORRECT :

If there is a valgus deformity of greater than 15 degree, both the iliotibial band and the popliteal tendon will often need to be released
The popliteus should be released before the lateral capsule
The iliotibial band should be released with a Z-type release if the knee is tight in flexion
The osteophytes are the the last structures that should be removed
If the lateral collateral ligament is released, there is no need to consider the use of a constrained-type prosthesis

8. A 12 year old girl attends the outpatient clinic for follow up of thoracic spine scoliosis. The cobb angle is measured at 30 degrees and she is found to be Risser grade 2. The best management option would be:

Posterior deformity correction and spinal fusion
Anterior release and posterior deformity correction and spinal fusion
Brace
Repeat X-ray in 6 months
Observation

9. Comparing total hip replacement for displaced femoral neck fracture to hemiarthroplasty, total hip replacement would be expected to result in :

Increased rate of revision surgery
Increased acetabular wear
Reduced need for blood transfusion
Poor long term patient satisfaction
Reduced dislocation rate

(Question 9 of 10)

10. During a primary total knee replacement on a patient with previous fixed flexion deformity, you complete the distal femur and proximal tibia cuts. The gap is tight in extension, but balanced in flexion, what is the most appropriate first step to address this

Resect more distal femur
Posterior capsule release
Resect more tibia
Thinner tibial insert
Increase size of femoral component
