Background:. An unanswered question with open tibial fractures is whether the type of flap used affects hardware retention. Flap survival may not equate hardware retention or limb salvage. In this study, we performed a 10-year single institution review and analysis of all patients who had placement of hardware for open tibial fractures followed by flap coverage. Methods:. Inclusion criteria consisted of patients who underwent pedicled or free flap coverage of Gustilo IIIB or IIIC tibial fractures requiring open reduction and internal fixation. Outcomes and complications were statistically analyzed based on flap type. Flap type was stratified into free versus pedicled flaps and muscle versus fasciocutaneous flaps. Primary outcome measures included hardware failure and infection requiring hardware removal. Secondary outcome measures included limb salvage, flap success, and fracture union. Results:. Overall primary outcome measures were better for pedicled flaps (n = 31), with lower rates of hardware failure and infection (25.8%; 9.7%) compared with free flaps (n = 27) (51.9%; 37.0%). Limb salvage and flap success was not different comparing pedicled and free flaps. There was no significant difference in outcomes between muscle and fasciocutaneous flaps. Multivariable analysis showed that patients who had free versus pedicled flaps or muscle versus fasciocutaneous flaps had a higher chance of hardware failure. A formal orthoplastic team was established in the period from 2017 to 2022, after which flap numbers were higher and hardware failure less for pedicled and fasciocutaneous flaps. Conclusions:. Pedicled flaps were associated with lower rates of hardware failure and infection requiring hardware removal. A formal orthoplastic team improves hardware-related outcomes.
