Study summary

Majority of previous classifications based on two-dimensional images to analyze these complicated 3-D fractures. Small or delicate changes in rotation and positioning can result to considerable disagreement in the interpretation of standard radiographs. Therefore, a classification system which had a better reliability and reproducibility for the fractures is warranted and helpful for orthopedic surgeons. Furthermore, CT and 3-D CT construction images with high resolution give a much clearer view of the pattern of proximal humeral fractures. Edelson proposed a new three-dimensional classification for fractures of the proximal humerus. The results concluded that it was a useful in classifying these injuries with reasonable interobserver reliability.

It could be hypothesized that patients with proximal humeral fractures would benefit from this 3D classification, but there is a scarcity of application of the classification in large samples. T

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 23, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
