OpenSurgiSim Software is a surgical training module for orthopaedic surgeons to learn accurate correction of complex bone deformities. OpenSurgiSim is a cloud-based software consisting of three main modules:
1) Surgery-Planning Module: This module will help trainee surgeons in learning the planning of the complex bone deformity corrections on x-ray images. This module is further divided into two sub-modules - Guided and Non-Guided Planning. The Guided Planning sub-module consists of set of surgical cases already planned by Expert Trainer surgeons which needs to be followed by the Trainee surgeon. The Non-Guided Planning sub-module consists of set of surgical cases where Trainee surgeon has to plan the cases by himself without any guidance.
2) Psychomotor-AR Module: In this module, trainee surgeons will be able to download 3D files of a smartly designed 3D printable modular-kit that can be assembled to simulate a variety of bone deformities. Surgeons will 3D print the modular kit, assemble the physical module parts and use a webcam-based augmented reality system to practice psycho-motor skills. This module is further divided into two sub-modules - Guided and Non-Guided Psychomotor Planning. The Guided Planning sub-module consists of set of surgical cases already planned by Expert Trainer surgeons which needs to be followed by the Trainee surgeon. The Non-Guided Planning sub-module consists of set of surgical cases where Trainee surgeon has to plan the cases by himself without any guidance.
3) Self-Assessment Framework - The Self-Assessment module is based on the Self-Assessment Framework developed by the OpenSurgiSim team. The Self-Assessment is integrated into both the previous modules - Surgery-planning and Psychomotor module. It consists of analytics and scoring system which helps Trainee surgeons to self-assess how well they have learned as they go through each stages of Guided Surgery-planning Guided Psychomotor Planning. It also helps them to self-assess how skillfully they will perform under the non-guided Surgery-planning and Psychomotor part through the smart automatic scoring system which has been developed after benchmarking the scoring system with respect to the skills of Expert Trainer surgeons.
OpenSurgiSim access and requirements[edit | edit source]
OpenSurgiSim, being a cloud-software, can be easily accessed anywhere anytime via a computer connected to the internet, at www.opensurgisim.com. To use the software, a trainee has to signup and create an account. Once signed up, the user can login anytime and undergo training. All the information and progress of the training is automatically stored in the cloud.

Surgery-planning module[edit | edit source]
This module of OpenSurgiSim is to train surgeons to perform surgery planning of complex lower-limb bone deformities using digital X-ray images, through many case studies. The case-studies include real-patient digital X-ray images on which an expert surgeon has already planned the surgeries. The module has guided as well as non-guided case-studies. In a guided case study, trainee can follow the step-by-step guidance displayed on the screen to perform the planning. In the non-guided case study, trainee will perform the planning without the benefit of the guidance. At every critical step of the planning, the software will ask questions to assess the trainee performance and calculate the score for the case.

Psychomotor-AR module[edit | edit source]
This module of OpenSurgiSim is to train surgeons to apply the principles that are learnt in the planning case-studies onto the physical bone models, through various deformity cases. For this, the trainee will need a computer, a web camera, a few clamps/fixtures to create a training-setup. The trainee will also need basic clinical-tools for drilling & cutting the sawbones (either an orthopaedic power drill or regular battery operated drill can be used). Finally, the physical bone models will be in the form of modular kit. The parts of the kit can be assembled into various deformed bones of different case-studies.

Self-assessment framework[edit | edit source]
The software determines a score for each case study based on its automatic performance measurement technology. The performance measurement is based on responses given by trainee in each question of planning case study and automatic measurement of drilling, cutting and correction errors in each psychomotor cases. Based on the scores of each case study, the overall score, score varying with training completion, comparison with expert scores and category score is presented to the trainees, for methodological improvement in their training pathway.
