Insights
Pediatric supracondylar humerus fractures are common. The Gartland classification shows moderate to full agreement among surgeons for classifying these elbow injuries, guiding treatment decisions.
Area of Science:
- Orthopedic Surgery
- Pediatric Orthopedics
- Radiographic Interpretation
Background:
- Extension-type pediatric supracondylar humerus fractures represent a significant cause of pediatric elbow trauma hospitalizations.
- The Gartland classification system is the standard for managing these fractures, differentiating treatment based on injury type (Type I: cast immobilization; Types II & III: operative intervention).
- Previous studies report moderate to full interobserver reliability for the Gartland classification, comparable to other established systems.
Purpose of the Study:
- To evaluate the interobserver and intraobserver reliability of the Gartland classification system in classifying pediatric supracondylar humerus fractures.
- To assess the consistency of treatment recommendations (cast immobilization vs. operative intervention) based on Gartland classification.
Main Methods:
- Four fellowship-trained pediatric orthopedic surgeons reviewed radiographs of 72 pediatric supracondylar humerus fractures.
- Surgeons classified fractures using the Gartland system and recommended treatment (casting or closed reduction and pinning).
- Interobserver and intraobserver reliability were statistically analyzed.
Main Results:
- Moderate agreement was observed when comparing all fractures and specifically Type I and Type II fractures.
- Full agreement was achieved for Type III fractures among the surgeons.
- Intraobserver reliability demonstrated full agreement across all classifications.
- Treatment recommendations differed in 35% of cases based on fracture classification.
Conclusions:
- The Gartland classification demonstrates moderate to full reliability for pediatric supracondylar humerus fractures, particularly for Type III injuries.
- While classification reliability is generally good, variations in treatment recommendations highlight potential areas for improved consensus in managing these common pediatric elbow fractures.
Abstract:
The extension-type pediatric supracondylar humerus fracture accounts for nearly two-thirds of all pediatric hospitalizations due to elbow trauma. The Gartland classification guides the standard of care for treatment of this entity. Type I injuries are treated with cast immobilization while type II and III injuries are treated operatively. The reported interobserver reliability ranges from moderate to full agreement, which is on par with other frequently referenced classification systems such as Lauge-Hansen for adult ankle fractures. In this study, 4 fellowship-trained pediatric orthopedic surgeons reviewed radiographs of 72 pediatric supracondylar fractures and classified them based on Gartland's system. They recommended their preferred treatment of cast immobilization for type I fractures and of closed reduction and pinning in the operating room for type II and type III fractures. The interobserver and intraobserver reliability for each set of radiographs was then analyzed. There was moderate agreement comparing all fractures and comparing types I and II fractures, while there was full agreement for type III fractures. There was full agreement for the intraobserver reliability. The preferred treatment (casting vs operative intervention) differed in 35% of patients, if based on the fracture classification.

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...
