Introduction:
The Lagrange and Rigault classification was designed to describe extension-type supracondylar fractures of the humerus. It can also help in treatment decision-making.
Hypothesis:
The reliability of this classification has not yet been proven. The goal of this study was to assess this system's intra- and interobserver reliability.
Methods:
One hundred supracondylar fracture radiographs were randomly retrieved and reviewed by five different observers on two occasions in a different order. The kappa index was used to calculate the intra- and interobserver reliability.
Results:
Intraobserver reliability was 0.76 and interobserver reliability was 0.69.
Discussion:
The study shows good intra- and interobserver reliability. The Lagrange and Rigault classification has similar reliability to other supracondylar fracture classifications.

Fractures: Bone Repair
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 procedure...
