A double stemmed flexible hinge implant was designed in 1974 for use with the Mayo type resection arthroplasty of the first metatarsophalangeal joint. Press-fit titanium grommets were developed in 1985 to protect the implant midsection from sharp bony edges and shearing forces that can lead to implant abrasion or fracture, and particulate synovitis. The study of 90 first metatarsophalangeal joint implant arthroplasties performed with encircling press fit titanium grommets showed favorable bone response around the implant stems and the bone to grommet interface, with absence of complications relating to particulate reactivity, implant or grommet fracture. These findings suggest that the grommets effectively protect the implant to bone interface, improve implant durability, and prevent particulate synovitis.
1974年设计了一种双柄柔性铰链植入物，用于第一跖趾关节的梅奥型切除关节成形术。1985年开发了压配合钛索环，以保护植入物中部免受尖锐骨边缘和剪切力的影响，这些力可能导致植入物磨损或骨折以及颗粒性滑膜炎。对90例采用环绕式压配合钛索环进行的第一跖趾关节植入关节成形术的研究表明，植入物柄周围以及骨与索环界面处的骨反应良好，没有与颗粒反应性、植入物或索环骨折相关的并发症。这些发现表明，索环有效地保护了植入物与骨的界面，提高了植入物的耐久性，并预防了颗粒性滑膜炎。
