Abstract
Fractures of the metatarsal bones are among the most common injuries of the foot. Specifically, fifth metatarsal fractures account for 40-75% of all foot fractures. It is common for fifth metatarsal fractures to develop healing complications, including bone non-unions. There is currently no consensus on the optimal choice of treatment and management of these fractures that yield complete bone union. Therefore, non-union healing complications remain a significant problem in orthopedics. A prediction model for the development of non-unions would be a powerful clinical tool to limit modifiable causes for non-union when making decisions about treatment and management for this injury. This study aims to address the gap in a clinical prediction model for non-union by targeting high risk patient features that contribute to non-union. Using correlation analysis, we found 13 high-risk patient features that were significantly correlated with non-union development. These features were found across different categories: patient demographics (2), chronic diseases (6), and medication use (5). This study can provide clinicians with important insight when they are trying to determine the most effective treatment approach and management of fifth metatarsal fractures in patients with specific demographic characteristics, co-morbidities, and medication use.
