Letounel and Judet classification of Acetabular fracture

The image shows a classification of acetabular fractures divided into two categories: elementary fractures and associated fractures. Here's a brief explanation of each type:
Elementary Fractures:
1. **Anterior Wall**: A fracture involving the front part of the acetabular wall.
2. **Anterior Column**: A fracture involving the front part of the acetabulum, extending into the iliac wing.
3. **Transverse**: A horizontal fracture dividing the acetabulum into superior and inferior parts.
4. **Posterior Wall**: A fracture involving the back part of the acetabular wall.
5. **Posterior Column**: A fracture involving the back part of the acetabulum, extending into the ischium.
Associated Fractures:
1. **Both Columns**: Fractures involving both the anterior and posterior columns of the acetabulum.
2. **Posterior Column with Posterior Wall**: A fracture that includes both the posterior column and the posterior wall.
3. **Anterior Column with Posterior Hemi-transverse**: A fracture involving the anterior column with a partial transverse fracture extending to the posterior column.
4. **T-Shaped**: A fracture that creates a T-shape, involving both columns and transverse elements.
5. **Transverse with Posterior Wall**: A transverse fracture that also involves the posterior wall.
These classifications are important for determining the appropriate treatment and surgical approach for acetabular fractures.
