关节解剖和功能的计算模型为生物力学家、医生和物理治疗师了解重复性运动、急性损伤和退行性疾病的影响提供了一种手段。例如,有限元模型可用于预测手术干预的结果或改进假体植入物的设计。多年来,无数的模型被开发出来,以解决无数的骨科手术。不幸的是,很少有研究纳入了针对患者的模型。从历史上看,由于与模型开发相关的需求,已经使用了基线解剖模型。此外,手术模拟带来了额外的建模挑战。目前的啮合方法不容易适应植入物。我们的目标是开发一套工具(虚拟仪器和指南),使外科手术过程易于模拟,并促进全六面体有限元网格定义的发展。
Computational models of joint anatomy and function provide a means for biomechanists, physicians, and physical therapists to understand the effects of repetitive motion, acute injury, and degenerative diseases. Finite element models, for example, may be used to predict the outcome of a surgical intervention or to improve the design of prosthetic implants. Countless models have been developed over the years to address a myriad of orthopaedic procedures. Unfortunately, few studies have incorporated patient-specific models. Historically, baseline anatomic models have been used due to the demands associated with model development. Moreover, surgical simulations impose additional modeling challenges. Current meshing practices do not readily accommodate the inclusion of implants. Our goal is to develop a suite of tools (virtual instruments and guides) which enable surgical procedures to be readily simulated and to facilitate the development of all-hexahedral finite element mesh definitions.
