  • the object of the invention is to provide navigator software, which measures the angle of the osteotomy, which is used to measure, find the deformity angle and define the curvature of the bones of the patient with the help of markings on the loaded image, both by uploading X-ray or three-dimensional tomography images on the computer to the osteotomy measurement navigation system and a osteotomy guide, which fixes it to the patient's bone with a pin during surgery by printing with software guidance a osteotomy guide specially designed for each patient with a 3D printer, and which allows the physician to cut the bone piece to be cut (osteotomy) from the patient to correct the curvature of the bone at the desired angle with zero error, in the surgical treatment of a disease called Hallux Valgus, Hallux Varus and Hallux Rigitus in medical language, which is defined as horn or hammer toe among the people, which occurs on the feet.
  • An object of the invention is to provide personal osteotomy planning software and personalized smart bone cutting guide.
  • An object of the invention is to measure the curvature of the bone of each patient and to produce 3D printed guides at the angle specific to that patient. In addition, whatever type of technique the doctor wants to use, it is to put forward a system that will print a guide suitable for that technique.
  • An object of the invention is to introduce a system that calculates and plans personal osteotomy, which calculates how much piece of bone is removed at which angle and how much piece is removed from the bone in order to define and correct deformity specific to the person on the images of X-ray or tomography films. It is aimed to complete the surgery with zero error and personal angulation by printing a personal osteotomy guide with a 3D printer made of disposable PVC, POLYETHILEN, ABS raw materials specially designed for each patient with the data and directions of this system.
  • the object of the invention is to present a system and guide that will enable the cases performed without the use of a guide with classical surgery to be performed with more accurate and custom corrections and osteotomy.

  • the software program (20) is web-based.
  • markings are made on the x-ray or tomography film by the doctor. While making the said markings, a web-based navigation system that determines the measuring angle of osteotomy is used. These markings can preferably be done by means of a computer mouse or it can also be done by touch depending on the feature of the device on which the software program is installed.
  • the uploaded images are processed by the software program (20) using the image processing method. Angular deformity etc. in this processing properties are automatically measured by the software program (20).
  • the HVA Heat Valgus Angle
  • IMA Intermetatarsal Angle
  • Hallux valgus angle This angle is the most commonly used angle for the evaluation of hallux valgus. It evaluates the angle between the 1 . metatarsal and the long axes of the proximal (closer to the heart) phalanx.
  • metatarsal and proximal phalanx axes, proximal and distal (far from the heart) bone articulation surfaces that divide into two, that is, their midpoints are marked with the help of mouse, the software program (20) automatically creates lines between points. Its normal value is between 8°-10°. Angles that are higher or lower form the basis for the surgeon to define the deformity and for the surgical operation.
  • intermetatarsal angle measurement It evaluates the angle between the long axes of the 1 . and 2. metatarsals. Normal angulation is considered to be 10° or less. It is a practical classification system accepted by the use of hallux valgus angle and 1 . intermetatarsal angle measurements from angular measurements.
