Summary
This study identified distinct injury patterns in flexion tibial plateau fractures (FTPFs) using 3D CT simulation. Understanding these patterns aids surgeons in choosing optimal treatment strategies for FTPFs.
Area of Science:
- Orthopedic Surgery
- Radiology
- Biomechanical Engineering
Background:
- Flexion tibial plateau fractures (FTPFs) are complex injuries requiring precise classification.
- Current classification systems may not fully capture the nuances of FTPF injury mechanisms.
Purpose of the Study:
- To identify and classify distinct injury patterns of FTPFs using 3D CT simulation technology.
- To investigate the association between these identified FTPF injury patterns and concomitant injuries.
Main Methods:
- Retrospective review of 108 FTPF cases treated between 2016-2018.
- Utilized 3D CT simulation to reconstruct knee joint positions at the time of injury.
- Calculated tibial translation and rotation using Mimics software to deduce injury patterns.
Main Results:
- FTPFs were subclassified into five groups based on fracture region and rotation (unicondylar and bicondylar).
- Significant differences in concomitant injuries (posterolateral collapse/split, anterolateral, proximal fibular fractures) were observed between flexion-internal rotation (Type IIB) and flexion-external rotation (Type IIC) bicondylar fractures.
Conclusions:
- 3D CT simulation enables a detailed subclassification of FTPFs based on injury patterns.
- This classification aids surgeons in better understanding FTPFs and tailoring treatment strategies.

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.
