BACKGROUND Our primary aim was to develop a prediction model for return to the operating room (OR) after open finger fractures by studying the reoperation rate of open finger fractures based on patient demographics, injury mechanism, injury severity, and type of initial surgical fixation. The secondary aim was to study the predictors for secondary surgery due to nonunion, postoperative infection, and secondary amputation. METHODS In the retrospective chart review, 1321 open finger fractures of 907 patients were included. Demographic-, injury-, and treatment-related factors were gathered from medical records. RESULTS We found that open fractures involving the thumb had lower odds of undergoing secondary surgery. Crush injury, proximal phalangeal fracture, arterial injury, other injured fingers, and other injuries to the ipsilateral hand were associated with higher odds of undergoing secondary surgery. However, the associated factors we identified were not powerful enough to create a predictive model. Other injury to the ipsilateral hand, vein repair, and external fixator as initial treatment were associated with postoperative nonunion. Crush injury and proximal phalangeal fracture were associated with postoperative infection. No factors were associated with secondary amputation. CONCLUSIONS A quarter of open finger fractures will likely need more than one surgical procedure, especially in more severely injured fingers, due to crush or with vascular impairment. Furthermore, fractures involving the thumb have less reoperation, while fractures involving the proximal phalanx have poorest outcomes.
