Objective: To Study a new internal fixation method for treatment of tibial fractures and the effects of this technique on the blood supply to the tibial.Method:Five fresh human cadavers (10 calves) were divided into two groups. On one side, the plate was inserted using a conventional plate osteosynthesis (CPO) technique. On the contralateral side, the plate was inserted percutaneously using a minimally invasive plate osteosynthesis (MIPO) technique. After plating, casting solution was injected through the popliteal artery. Blood vessel casting specimen with tibial bone was then made. The blood vessel net of two sides was observed and the periosteal arteries and the nutrient arteries of two sides were contrasted.Results: The periosteal arteries and the nutrient arteries showed intact flow in all specimens in MIPO group, while CPO group specimens showed interruption of flow. Conclusion: MIPO is superior to the CPO in maintaining arterial tibial vascularity and perfusion. It is an easy method of the minimally invasive treatment of the tibal fracture,and a biological internal fixation with good effects.
