<strong>Introduction:</strong> Intramedullary nailing is synthesis and  consolidation of fracture fragments with the main goal<br />to gain strength and permanent placement of the implants. Two techniques of intramedullary osteosynthesis are used: with dynamic or with static intramedullary nail. Dynamization include conversion of static nail by removing screws from the longest fragment. The aim of this study is to determine whether there is a difference in the speed and quality of healing of the type A and B fractures of the femur and tibia treated by static or dynamic intramedullary nails and to compare the results.<br /><br /><strong>Methods</strong>: The study was conducted on a total of 129 patients with closed fractures of the diaphysis of the femur and tibia type A and type B. Patients were divided into two groups, based on the applied operating method, static or dynamic intramedullary osteosynthesis.<br /><br /><strong>Results:</strong> The average number of weeks of healing femoral and tibial fractures was slightly in advantage of static intramedullary osteosynthesis, it was 17.08 weeks (SD=3.382). The average number of weeks of healing in 23 patients with fractures of the femur, treated by dynamic intramedullary osteosynthesis was 17.83 (SD=2.978).<br /><br /><strong>Conclusion:</strong> We can conclude that static intramedullary nailing osteosynthesis unable movements between fragments which directly stimulates bone formation and formation of minimal callus. Static intramedullary ostesinthesys resolve the problem of stabilizing the fracture, limb shortening and rotation of fragments.
