Summary

The developed system allows to select the bone in the image and build their three-dimensional model. Using this model, the developed module of planning allows to calculate the most appropriate parameters of the surgery and perform a virtual dissection and correction of the bone model.

Description

The system makes it possible to select the bone in the image and build their three-dimensional model. Using this model, a special module of planning allows us to calculate the most appropriate parameters for the surgery and perform a virtual dissection of digital model of the bone. In the planning phase of surgery the system allows us to calculate the parameters of surgical intervention on the basis of user-spaced markers, defining the position of anatomical landmarks, which allow to calculate the geometric characteristics of bone.
Nowadays the software tools for the planning of oblique and rotational osteotomy of the hip, the planning of surgical treatment of certain types of lesions of the anterior foot and wrist are developed.
Additional system capabilities -to export models of segmented objects into XML-files.

Technology type

Technical advantages and economic benefits

  1. The planning time of the surgery when you use the System is much less than the time of planning when you use traditional method of radiographs.
  2. The user can plan the surgery by conventional methods using simulated radiographs.
  3. The system allows to surgery on a virtual model that allows the orthopedic surgeon to evaluate the possible effects of the operation at the stage of planning.
  4. Orthopedic surgeon can not just choose a different cutting tools (one-and two-plane blades), but also adjust their size in modeling of the osteotomy.
  5. The system presents interest for health training institutions as a computer orthopedic surgical simulator.

Technology differentiation and uniqueness

The system is a fundamentally new development, due to the possibility of modeling the surgery(rotational osteotomy) and predicting its possible consequences still in the planning stage.
In comparison with existing analogues, the system has the following advantages:
- System does not require a computer to a tomographic scanner (planning for an surgery using the System, the user releases the time of the imager to scan the other patients);
- Gives you a choice of tools to view tomographic images with the capacity to conduct the necessary planning for orthopedic surgery of measurements and calculations;
- Has the flexibility of approaches to planning (the ability to both automatic and manual setting operation parameters).

Context in which technology was identified

The experimental sample of the System has been implemented in the following medical and health training institutions:
- RSPC Traumatology and Orthopedics;
- Belarusian Medical Academy of Postgraduate Education;
- Belarusian State Medical University;
- 6 th Clinical Hospital, Minsk.
