Predictors of reoperation following operative management of fractures of the tibial shaft.

Accurate prediction of likelihood of reoperation in patients with tibial shaft fractures would facilitate optimal management. Previous studies were limited by small sample sizes and noncomprehensive examination of possible risk factors. We conducted an observational study to determine which prognostic factors were associated with an increased risk of reoperation following operative treatment in a heterogeneous population of patients with tibial shaft fractures. Retrospective observational study. Level 1 trauma center. We identified 200 patients with tibial shaft fractures from two university-affiliated centers. Two reviewers independently abstracted data regarding 20 possible prognostic variables, reviewed preoperative and postoperative radiographs, and documented reoperations (defined as any surgical procedure
