Classification of Bones

Classification of Bones

The bones of the human skeletal system are of varied shapes, sizes, and functions. They can be classified based on their shape and function into four major classes: long bones, short bones, flat bones, and irregular bones. Some classifications include a fifth type, the sesamoid bones, as a separate class, whereas others categorize them under short bones.
Long and Short Bones
The appendicular skeleton, particularly the upper and lower limbs, is primarily made of long and short bones. The long...

Background:

Tibial plateau fractures are complex intra-articular injuries requiring precise classification and surgical planning.
Current methods may present challenges in accurately assessing fracture patterns and planning interventions.

Purpose of the Study:

To evaluate the utility of 3D printing in classifying and planning surgical treatment for complex tibial plateau fractures.
To assess the impact of 3D printed models on surgical outcomes and anatomical restoration.

Main Methods:

Review of 54 complex tibial plateau fractures treated between January 2017 and January 2019.
Preoperative spiral CT scans were used to create 1:1 scale 3D printed models.
Surgical approaches, fracture reduction, and plate placement were planned using the 3D models.

Main Results:

3D models accurately represented fracture displacement and tibial plateau collapse.
Preoperative planning with 3D models facilitated precise reconstruction strategies.
All 54 patients demonstrated significant improvement in tibial plateau anatomical structure post-surgery.

Conclusions:

3D printing is a valuable tool for classifying and preoperative planning of complex tibial plateau fractures.
This technology enhances surgical outcomes and improves anatomical restoration of the tibial plateau.
The study supports the use of 3D printing for complex fracture management (Level of Evidence IV).
