The fundamental understanding of load transmission and motion behavior of the eight carpal bones, which are connected by a complex soft tissue apparatus, and altogether support the movement for the middle hand against the lower arm, is currently missing. Therefore, surgical therapies of the wrist are based on the individual experience of the surgeon, and the therapeutically results vary strongly. The goal of this project is a valid multi-body-simulation model of the human wrist joint for the solution of the inverse-dynamic and forward-dynamic problem. During developing of the wrist joint model, there will be used different methods for the investigation and modeling of the measured bony motion behavior and the surface models to establish characteristic information of the motion and load transmission between the wrist bones. For the first time the advantages of in vivo and in vitro investigation of the motion behavior of the different wrist bones will be combined. The interdisciplinary approach (medicine, biomechanics) guarantees the validity and medical relevance. With the developed test setup and the developed investigation methods there will be the chance to investigate physiologically and also the pathologically and surgically-modified wrist joints. Thus, for the first time a model-supported comparison of surgical interventions will be possible based on objective criteria.

目前缺乏对八根腕骨的载荷传递和运动行为的基本理解，这八根腕骨由复杂的软组织装置连接，并且共同支持中手对抗下臂的运动。因此，手腕的手术治疗是基于外科医生的个人经验，治疗结果差异很大。本计画的目标是建立一个有效的人体手腕关节多体仿真模型，以解决手腕关节的逆动力学与正动力学问题。在腕关节模型的开发过程中，将使用不同的方法对测量的骨骼运动行为和表面模型进行调查和建模，以建立腕关节骨骼之间的运动和载荷传递的特征信息。第一次的优势，在体内和体外调查的运动行为的不同的手腕骨将结合起来。跨学科的方法（医学，生物力学）保证了有效性和医学相关性。通过开发的测试装置和开发的研究方法，将有机会研究生理学以及病理学和解剖学改变的腕关节。因此，第一次有可能根据客观标准对手术干预进行模型支持的比较。
