Provided is a design concept for a bone fixating device that can be used both for closing the physys and also for fixing fractures by means of a tension band, wherein the device is based on the concept of two fixed ends joined by flexible wire, which facilitates both its installations and use, which also allows to perform a minimally invasive surgery due to the reduced size of the implant, whose profile must be as low as possible in order to avoid tissue damage during surgery. Thus, the design of the device allows the fastening screws to be located as far as possible from the physys, i.e. in the safe zone, reducing ischemia in the physys and, also, allowing for the surgery to be handled percutaneously.
