Question

Multi fragmented fracture fixation in dogs with dynamic compression plate is called

• A. Neutralization Plating
• B. Dynamic Compression Plating
• C. Reconstruction Plating
• D. Buttress Plating

Hint:

Bone Plating Functions:
Buttress Bridging $\rightarrow$ Multi-fragmented Comminuted non-reducible fractures.
Compression $\rightarrow$ Simple transverse fractures.
Neutralization $\rightarrow$ Protects lag screws on oblique fractures.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Orthopedic plate biomechanical functions: dynamic compression (transverse), neutralization (lag-screw protected), and buttress/bridging (comminuted/multi-fragmented non-reducible gaps).

Step 2: Detailed Explanation:
Biomechanical functions of bone plates (AO/ASIF classification):
1. Buttress (Bridging) Plating: Applied to highly comminuted, multi-fragmented fractures where anatomical reduction of intermediate fragments is impossible. The plate spans the entire multi-fragmented zone, anchored only in the intact proximal and distal main bone segments, transmitting $100\%$ of the axial, bending, and torsional load across the defect like a buttress internal splint.
2. Compression Plating: Compresses simple transverse fractures.
3. Neutralization Plating: Protects interfragmentary lag screws across reducible oblique fractures.

Step 3: Final Answer:
Therefore, multi-fragmented fracture fixation with a plate is called Buttress Plating, matching option (D).
