Canal encroachment without neurological deficit

4. 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:

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

5. The highest concentration of proteoglycans is found in which layer of the articular cartilage?

Middle
Superficial
Deep
Tidemark
Calcified

(Question 5 of 10)

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

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

(Question 6 of 10)

7. 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
Observation
Anterior release and posterior deformity correction and spinal fusion
Repeat X-ray in 6 months
Brace

(Question 7 of 10)

8. 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
Increase size of femoral component
Resect more tibia
Thinner tibial insert

(Question 8 of 10)

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

The popliteus should be released before the lateral capsule
If the lateral collateral ligament is released, there is no need to consider the use of a constrained-type prosthesis
The osteophytes are the the last structures that should be removed
The iliotibial band should be released with a Z-type release if the knee is tight in flexion
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

(Question 9 of 10)

10. The safe insertion zone of acetabular screws in total hip replacement is :

Anteroinferior
Posterolateral
Anterosuperior
Posteroinferior
Posterosuperior
