Complex kinematics, anatomical features, and load distribution have contributed to the poor function of constrained and semiconstrained cemented arthroplasties of the elbow. Resurfacing by porous-coated components has the potential, by reproduction of normal joint geometry and restoration of ligament balance, to re-create relatively normal kinematics and load-bearing and provide relief of pain. A method was developed to provide information on the geometry of the lower humeral joint surface and olecranon fossa. The information gained was used to design components to resurface the trochlea, capitellum, and olecranon fossa. A technique was also developed to remove a minimal amount of subchondral bone from the ulna and humerus in a precisely directed fashion for exact fit of the porous-coated components.
复杂的运动学、解剖学特征以及负荷分布导致了肘关节受限和半受限骨水泥型关节成形术功能不佳。采用多孔涂层组件进行表面置换，通过重现正常关节几何结构和恢复韧带平衡，有可能重新建立相对正常的运动学和负荷承载能力，并缓解疼痛。已开发出一种方法来获取有关肱骨下端关节面和鹰嘴窝几何形状的信息。所获得的信息被用于设计用于置换滑车、肱骨小头和鹰嘴窝的组件。还开发了一种技术，以精确的定向方式从尺骨和肱骨上去除最少数量的软骨下骨，以便多孔涂层组件能精确适配。
