Abstract
Early prediction of the union helps for timely
intervention, reduction of hospitalization, treatment costs, and disability in
cases of nonunion. With this in mind, we tried to find how long any cortical
bridging predicts the union in femoral shaft fractures. A prospective study of
113 femoral shaft fractures treated with reamed, locked intramedullary nailing
was performed. Radiographs were taken during months 2 to 4, 6, 9, and one-year
follow-up. The cortical bridging (presence and number) was assessed by
anterior-posterior and lateral views. The ROC curve provides the prediction of
the union. The overall nonunion rate was 10.6% (12 of 113 fractures). Age and
diabetes mellitus were statistically significant with nonunion (p value <
0.001). The final analysis demonstrated that any cortical bridging at four
months postoperatively was the most accurate and earlier indicator (105 of 113,
92.9% accuracy), while it was 84.9% at six months in bicortical and 80.5%
accuracy at nine months in tricortical bridging. Low-cost and simple
radiographic imaging presents cortical bridging in any form 4 months after
surgery that precisely predicts a union in femoral shaft fractures.
