Blinded diagnostic study reveals 74% accuracy in predicting nonunion in tibia fracture patients, suggesting earlier evaluation may prevent delayed reoperation.

Key Points

To evaluate whether orthopedic surgeons can accurately predict nonunion in patients with tibia fractures 3 months after intramedullary nailing using clinical history and radiographs.
A blinded questionnaire was administered to 3 fellowship-trained trauma surgeons based on a retrospective cohort of 56 consecutive patients treated between 2005 and 2009 with intramedullary fixation who had incomplete healing at 3 months.
Each patient case was converted into a standardized vignette displaying detailed clinical histories alongside 3-month radiographs to determine likelihood of progression to nonunion.
The overall diagnostic accuracy across all 3 surgeons was 74%, with an average sensitivity of 62%, specificity of 77%, and a positive predictive value of 73%.
Diagnostic accuracy reached 88% in the subgroup of 9 patients with diabetes.
Radiographic characteristics and initial injury mechanism served as the most frequently cited factors for determining nonunion risk.
