Surgeons' practical skill and the ability to improve their surgical capabilities are key to the attainment of successful orthopedic and trauma surgery outcomes. Hands-on, tactile exercises are crucial to an effective training concept. Conventional hands-on training for the distal interlocking of intramedullary nails tends to be cost-intensive; typically offered only in course events; limited to a specific number of applications; and lacking substantial data collection to qualitatively evaluate and measure participant performance.

The solution

These limitations are solved by DEHST. It is a compact, cost-efficient, and mobile concept for hands-on training, offering a novel, mixed-reality training experience and enhanced training scope. It features an artificial X-ray imaging engine that generates radiation-free simulated X-rays for a realistic training experience. Training can be tracked, and data can be collected and uploaded to the cloud. Users can access the data to get comprehensive training analytics and personalized skill assessment.

The first functional module for the free-hand distal interlocking training was developed in 2021, followed by a prototype module for proximal femoral nailing in 2023. The full Nailing Package, consisting of three modules covering the most relevant surgical skills for intramedullary nailing, was completed when the product 0-series was delivered for testing during the AO Davos Courses in December 2023.

The gamification and deliberate practice approach are ideal, to train and assess residents to be better prepared and proficient in the OR, ultimately benefiting the patient. In addition, DEHST’s low cost compared with other simulators allows for sustainable training and assessment of future orthopedic surgeons. The whole training and assessment station is compact, fits into a padded box, and can be easily transported to courses, events, or hospitals.

The future of DEHST is promising, with plans to expand its applications to more procedures and skills, covering the standard training needs of orthopedic residents worldwide.

Two validation studies have successfully assessed DEHST’s training efficacy:
