A lot different fixation methods are used in problems regarding Tibia bone. As in the other long bones (tubular), Intramedullary locking nail fixation for Tibia too is widespread used in the most recent years as indications are getting expanded. Nail systems which they function as providing locking in the proximal and distal with the interlocking screws is preferable. However elimination studies of nail and screw breakage problems and of difficulties in placing the distal locking screws (intensive scopy usage) are getting continued. New nail system searchings are for that ideal intramedullary fixation method has not be able to be developed. New intramedullary locking nail system which can include the advantages of the intramedullary fixation method the most, which its distal locking design is too different and can perform any required function with only one screw in every directions, has been developed for Tibia.
