Hypothesis
To analyze the reproducibility and intra- and interobserver agreement of the IDEAL classification for distal radius fractures.
Conclusion
The IDEAL classification had interobserver agreement levels ranging from poor to moderate, influenced by the physicians' training level.
Supporting Evidence
- The Cohen Kappa index values for intraobserver evaluation indicated poor to little agreement (-0.177–0.259).
- The Fleiss Kappa index values revealed little agreement among the resident group (0.277–0.383).
- Moderate agreement among hand surgeons (0.449–0.533) with statistical significance.
Takeaway
Doctors looked at X-rays of broken wrists to see how well they agreed on the IDEAL way to classify these injuries, and they found that more experienced doctors did better.
Methodology
This qualitative, analytical study evaluated 50 pairs of radiographs in two views assessed by ten observers with different levels of orthopedic training.
Limitations
The low number of observers for each category and the absence of hand surgery residents.
Participant Demographics
Participants included three hand surgeons, four general orthopedic surgeons, and three orthopedic residents.
