A composite fixation concept for porous-coated modular segmental bone and joint replacement prostheses was developed. Bone cement will provide immediate intramedullary stem stability, whereas autogenous bone grafts are applied over the porous-coated segmental shoulder region to achieve extracortical bone bridging and ingrowth for long-term biologic fixation. Bench tests, theoretical analyses, and animal experiments were performed to validate such a concept. Preliminary clinical trials have demonstrated extraordinary results as well as several limiting factors. Additional effort is required to perfect this innovative concept for prosthetic implant fixation.
一种用于多孔涂层模块化节段性骨与关节置换假体的复合固定概念被开发出来。骨水泥将提供即时的髓内柄稳定性，而自体骨移植应用于多孔涂层节段性肩部区域，以实现皮质外骨桥接和骨长入，从而实现长期的生物学固定。进行了台架试验、理论分析和动物实验来验证这一概念。初步临床试验已证明了非凡的结果以及一些限制因素。需要付出额外努力来完善这种用于假体植入物固定的创新概念。
