Question

Which of the following is true about the type of fixation shown in the image?

• A. Fracture tibia, ilizarov fixator
• B. Fracture tibia, spanning fixator
• C. Fracture femur, spanning fixator
• D. Periarticular fracture of knee, spanning fixator

Answer 1

The Correct Option is D

The image shows a type of external fixation that is used in the context of orthopedic surgery, particularly for the stabilization of complex fractures. The types of fixators mentioned in the options are associated with different fracture types and locations:

• Ilizarov Fixator: A ring fixator system generally used for tibial fractures, used for lengthening and deformity correction, but not typically referred to as a spanning fixator.
• Spanning Fixator: This is a type of external fixator that spans a joint to stabilize fractures around that joint. Most commonly used in knee, elbow, or wrist injuries.

Given the options:

• Fracture tibia, ilizarov fixator: Incorrect, as the question involves a spanning fixator, not an Ilizarov fixator.
• Fracture tibia, spanning fixator: Incorrect, as the context of "periarticular" (around the joint) specifically relates to the knee.
• Fracture femur, spanning fixator: Incorrect, as the fixation type is more relevant for periarticular knee fractures than for femur.
• Periarticular fracture of knee, spanning fixator: Correct, as this describes the use of a spanning fixator to stabilize a fracture surrounding the knee joint.

Thus, the true statement about the type of fixation shown in the image is:

Periarticular fracture of knee, spanning fixator
