Is the use of retrospectively collected radiographic scores an accurate method to determine time to union? A retrospective clinical cohort

Listen to this summary

The authors aimed to evaluate the accuracy of retrospectively collected radiographic scores in determining time to union (TTU) after intramedullary nailing of tibial shaft fractures. They found that the observed TTU significantly overestimated the predicted TTU by 34.2 days, indicating that this method of assessing TTU is inaccurate in clinical settings. This study underscores the limitations of using uncontrolled interval radiographic evaluations for determining TTU in orthopedic patients.
