Risk Factors for Post-Operative Nonunion of Tibial Shaft Fractures Based on a Path Analysis Model

Tibial shaft fractures is common long tubular fracture that account for about 13.7% of all fractures. And the incidence of nonunion of tibial shaft fracture varied from 1% to 80%. The investigators retrospectively analyzed the demographics of these participants in our hospital that occur long tubular fracture. One group is participants that existed fracture nonunion. And the other group is the participants that did not exist fracture nonunion. The investigators recorded twelve variables and confirm the risk factors by uni-variate Logistic regression analysis. Moreover, the investigators hope to establish the clinical pathway of various risk factors for fracture nonunion and affirm the importance of different risk factors.
