Abstract

Background

A minimally invasive spherical osteotomy assistant system (MISOS) based on a multi-axis surgical robot was designed to improve the control and precision of manual spherical osteotomy.

Methods

Based on human sawbone models, the feasibility of MISOS was verified by comparing the osteotomy centre deviation and the section curvature of the acetabulum, femur, and tibia.

Results

Compared with freehand spherical osteotomy, the MISOS system demonstrated superior centre deviation for the acetabulum (1.48 ± 0.93 vs. 11.15 ± 3.97 mm), femur (3.12 ± 0.75 vs. 8.81 ± 3.04 mm), and tibia (1.91 ± 0.84 vs. 7.33 ± 1.53 mm) as well as superior curvature deviation for the acetabulum (1.40 ± 0.08 vs. 3.16 ± 0.56 mm), femur (0.26 ± 0.07 vs. 0.491 ± 0.21 mm), and tibia (0.21 ± 0.02 vs. 0.46 ± 0.18 mm). These results indicate that MISOS can assist surgeons in performing accurate and stable spherical osteotomy.

Conclusion

The MISOS system demonstrates promise as a precise assistive tool for minimally invasive orthopaedic spherical osteotomy, with potential for broader clinical applications.

期刊介绍： The International Journal of Medical Robotics and Computer Assisted Surgery provides a cross-disciplinary platform for presenting the latest developments in robotics and computer assisted technologies for medical applications. The journal publishes cutting-edge papers and expert reviews, complemented by commentaries, correspondence and conference highlights that stimulate discussion and exchange of ideas. Areas of interest include robotic surgery aids and systems, operative planning tools, medical imaging and visualisation, simulation and navigation, virtual reality, intuitive command and control systems, haptics and sensor technologies. In addition to research and surgical planning studies, the journal welcomes papers detailing clinical trials and applications of computer-assisted workflows and robotic systems in neurosurgery, urology, paediatric, orthopaedic, craniofacial, cardiovascular, thoraco-abdominal, musculoskeletal and visceral surgery. Articles providing critical analysis of clinical trials, assessment of the benefits and risks of the application of these technologies, commenting on ease of use, or addressing surgical education and training issues are also encouraged. The journal aims to foster a community that encompasses medical practitioners, researchers, and engineers and computer scientists developing robotic systems and computational tools in academic and commercial environments, with the intention of promoting and developing these exciting areas of medical technology.
