The invention is a fixation system, which is developed for the treatment of diseases on cervical, thoracal and lumbar spine and especially to maintain the distance between two vertebras on the spine and achieve fusion, comprises of a main cage (2), at least one dynamic shaft (3) fitted into the main cage (2) in parallel with cage axis, at least one sharp blade (5) fixed with a fixation pin (4) on to the shaft (3), and at least two imaging pins (6) located in two different axis- which helps to locate/identify the struc tune under X-Ray imaging during a surgery. The invention relates especially to the sharp blade (5)—one of the system elements—which is turned 90° in the main cage (2) with the help of shaft (3), and penetrated into the vertebras with the help of sharp side surfaces (5.3), thus fixing the system within two vertebras, to prevent the displacement of the system within the vertebras and to prevent the usage of extra parts like plates which will disable migration or displacement of the system within the vertebras and to increase the system productivity.
