3-D classification for proximal humerus fractures
Official title: The Reliability and Reproducibility of Edelson Classification About Proxima Humeral Fractures
Run by Hebei Medical University Third Hospital · NCT04523415 · Data updated 2026-11-12
This project uses CT-based 3-D images to test whether a three-dimensional classification helps doctors categorize displaced proximal humeral fractures in adults.

Is this trial a fit for you?
✓Likely a good fit
Adults older than 17 with displaced proximal humeral fractures treated within three weeks who have complete CT and 3-D reconstruction data and clear demographic records are the ideal candidates.
✕Probably not a fit
Patients with open or non-osteoporotic pathological fractures, documented neurologic disease (e.g., syringomyelia), incomplete imaging or records, or who are not residents of the hospital's catchment area are unlikely to benefit from or be included in this analysis.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a retrospective observational review of patients with displaced proximal humeral fractures who have complete imaging and demographic records. Investigators will generate three-dimensional reconstructions (using Mimics with CT B30 data) and apply the Edelson 3-D classification to classify fracture patterns. The team will analyze interobserver reliability and reproducibility across a larger sample and correlate classification findings with available clinical data. All data are drawn from records at the Third Hospital of Hebei Medical University.
Why it matters
Potential benefit: If the 3-D classification proves reliable in a larger sample, it could give surgeons a clearer, more reproducible way to describe fractures, aiding surgical planning and potentially improving outcomes.
How similar studies have gone: Prior smaller series using Edelson's three-dimensional classification reported reasonable interobserver reliability, but large-sample validation remains limited.
