Background:
Although the concept of the "fix and flap" approach, in which definitive fracture fixation and flap coverage are completed in a single procedure at the earliest opportunity may seem ideal for the treatment of Gustilo type IIIB open fractures, the individual circumstances of patients, such as polytrauma or multiple fracture cases may not allow for the immediate fracture fixation and flap coverage ("fix and flap" approach). In our hospital, patients with Gustilo type IIIB open fractures are treated with definitive internal fixation of the fracture followed by staged flap coverage ("fix followed by flap" protocol) when the "fix and flap" approach was not feasible due to the patient's condition or difficulty in coordinating surgery schedules. The "fix followed by flap" protocol provides benefits in terms of flexibility in adjusting the surgical timetable, simplifying the planning of flap coverage following fracture fixation, and minimizing individual surgical invasion.
Methods:
We reviewed 10 cases of severe open fractures treated with the "fix followed by flap" protocol and evaluated their outcomes. All surgical procedures, including wound debridement, fracture fixation, and flap coverage, were performed by orthoplastic surgeons specializing in both fracture surgery and microsurgery including soft tissue reconstruction.
Results:
All free flaps survived, and no partial necrosis was observed. None of the patients developed postoperative deep infection up to the last follow-up. Fracture union was achieved in all patients with or without autologous bone grafts. The median time for union was 9.4 months (range, 4-12 months).
Conclusions:
This study presents favorable outcomes of treatment for Gustilo type IIIB open fractures with fracture fixation followed by staged flap coverage ("fix followed by flap" protocol). Despite a delay in flap coverage, the consistency of treatment provided by orthoplastic surgeons may have contributed to the favorable outcomes in this study.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
