Treatment for tibial fractures may occasionally be simple, but it may also be difficult. Whether the fracture is closed or open, soft tissue issues and infection associated to the fracture account for the majority of the challenges [7]. The infection incidence for open Gustilo type III tibial fractures might reach 25% [8]. The overall infection incidence for closed tibial fractures treated with open reduction and internal fixation with plate and screws was between 2.3 percent and 2.5 percent [9–10]
Debridement was the initial step in the traditional way of treating open tibial fractures, followed by the placement of a large external fixator or, where soft tissue injury and contamination were not severe, one stage debridement and internal fixation [11–12]. However, due to instability or inconveniency brought on by bulky external fixators, internal fixation with a plate or intramedullary locking nail may occasionally be required [13]. The risk of infection was considerable with one stage debridement and internal fixation for an open tibial fracture [14].
According to prior studies, the internal design of the locking plate osteosynthesis's biomechanical stability was superior to that of the standard dynamic compression plate [15]. Internal stability is provided by the locking mechanism between the screw head and the locking holes, which is independent of friction between the bone and the plate [16]. In published articles as an external fixator, locking plate might offer high bio-mechanical stability in axial compression and torsion tests [17–19]. Under tibial fracture osteosynthesis owing to open fracture or tibial infection for particular circumstances, the authors of various articles that have been published employed supra-cutaneous locking plates [20]. And positive clinical outcomes were obtained, the fracture healed, or the infection was under control. After debridement, supra-cutaneous locking plate fixation for open tibial fractures without substantial soft tissue open damage or soft tissue defect offers good stability and lowers the risk of infection from internal fixation [21–22]. External fixation with a supra-cutaneous locking plate as a definitive treatment for these particular patients with open tibial fractures without substantial soft tissue open damage or soft tissue defect and some closed tibial fractures with tension blisters not only shortens their hospital stay but also lessens the pain and expense of multiple surgeries.Supra-cutaneous locking plate fixation also eliminates the drawback of the bulky external fixator, which causes patients a great deal of inconvenience [23–24].
The use of supra-cutaneous locking plate fixation to treat closed tibial fractures, however, is controversial and was done in certain reports [21]. Even if there weren't many issues in the prior study, most physicians didn't agree since they were worried about an infection from a screw hole during personal hygiene. Nonetheless, internal fixation in such a state has a higher risk of infection since the soft tissue barrier was compromised in closed tibial fractures with extensive blisters. Accordingly, in our practice, the use of supra-cutaneous locking plate fixation appears reasonable. When internal fixation was used on patients who had significant blisters or soft tissue contusions, the risk of infection was high. The fractures healed with no infection after supra-cutaneous locking plate fixation. Supra-cutaneous locking plate fixation has the same risk of screw tract infection as an external fixator, but in our patients, the incidence is minimal, thus the screws didn't need to be taken out; instead, the patients only required to get oral antibiotic medication. However, having a shower for personal hygiene was forbidden for our patients even after the incision had healed, which may have contributed to the low occurrence of screw tract infections.
After surgical treatment of patients with closed tibial fractures, the infection rate was 1 percent [25]. In this sort of circumstance, debridement should remove any prior internal fixation devices, such as plates and screws or intramedullary nails [26]. An external fixator was used in a prior study following debridement to maintain fracture stability. But if a circular frame wasn't used, stability could not be as robust. If there was no significant bone defect, supra-cutaneous locking plate fixation might be utilized to maintain fracture stability following debridement until fracture healed, eliminating the discomfort of a large external frame [27–29]. After internal fracture treatment, we had instances of surgical site infection, but no significant bone defects. Before the supra-cutaneous locking plate was removed after the fracture healed, the infection was under control and the fracture had healed.The limitation of this study is that the patients with a supra-cutaneous locking plate were so specific that the sample size was too small.And this study can only explore the advantages of using a supra-cutaneous locking plate, and no valid inferences can be made.
