Non-vascularized Fibular Autograft and Locking Plate: A Solution to the Resistant Nonunion of a Tibial Metaphyseal Fracture.

ABSTRACT

The union of tibial fractures often raises concerns. In one such case, a 62-year-old female patient presented in our Emergency Room (ER) with a comminuted tibial metaphyseal fracture resulting from a traffic accident. The patient underwent three surgical procedures in the following two years. The first intervention was open reduction internal fixation (ORIF) with a plate and screws. The second intervention, which took place three months after the first surgery, addressed the union delay through implant removal and closed reduction and internal fixation (CRIF) with an antegrade intramedullary tibial nail. The third intervention addressed the implant failure and oligotrophic nonunion through the removal of the broken tibial nail and ORIF using a proximal tibia locking plate and screws, augmented with fibular shaft and reamed iliac crest autografts. We conducted frequent follow-ups with the patient and performed multiple X-rays to confirm and monitor the fracture union. At the last follow-up, two years after the last surgical intervention, imagistic investigations showed that the patient presented with fracture union, she could support her full body weight on the operated leg, and was able to walk and carry out normal daily activities. As such, we concluded that the surgical method chosen (ORIF with proximal tibia locking plate and screws, augmented with a fibula shaft strut and reamed iliac crest autograft) was a viable option to treat an aseptic oligotrophic nonunion in a high-energy comminuted tibia fracture.
