Abstract
This study compared biomechanical impacts of conventional open surgery (COS) and minimally invasive surgery (MIS) for spondylolisthesis using a musculoskeletal model with in-vivo data from 31 patients undergoing L4-L5 fusion. Pre- and post-operative conditions with simulated muscle injury were analyzed, focusing on kinematics, muscle forces, and adjacent segment loading. Both methods altered lumbosacral parameters, but COS caused greater lumbar-pelvic rhythm reduction (60% vs. 14%), largely due to decreased trunk flexion. MIS showed increased multifidus contribution and reduced adjacent loading, though it raised upper segment passive moment and compression. Findings suggest MIS better preserves stability and favorable biomechanics than COS.
期刊介绍：
The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
