Purpose:
Surgical simulations are becoming increasingly relevant in musculoskeletal training. They provide the opportunity to develop surgical skills in a controlled environment while reducing the risks for patients. For K-wire internal fixation in musculoskeletal surgery, a force feedback virtual reality (VR) simulator was developed. The aim of this study was to evaluate training results using this technology and compare the results with that of standard teaching on cadavers.
Methods:
Twenty participants attending an AO Trauma Course during 2020 were randomly allocated in 2 groups. On day 1, group A was trained by senior surgeons using a cadaver and group B was trained by the VR simulator for K-wire insertion in the distal radius. On day 2, all participants performed K-wire insertion on the cadaver model, without assistance, to validate the training effect.
Results:
On a surgical skills test, group B performed better than group A. In group B, the entry point of the first K-wire was closer to the targeted styloid process of the radius, and the protrusion of the K-wires into soft tissue was less than that in group A.
Conclusions:
Training with the VR simulator for K-wire insertion resulted in better surgical skills than training by a surgeon and cadaver model.
Clinical Relevance:
Training with the VR simulator provides the opportunity to improve and refine surgical skills without the risk of harming patients. It offers easier access, unlimited repetitions, and is more cost-effective compared with training sessions with cadavers.
