Abstract：
:In 1987, after 11 years of research, press fit titanium circumferential grommets were introduced for arthroplasty of the metacarpophalangeal joint to protect the flexible hinge implant midsection from sharp bony edges and shearing forces that can initiate implant abrasions and tears leading to implant fracture and formation of silicone wear particles. The effectiveness of the titanium circumferential grommets was assessed by comparing the results of 170 metacarpophalangeal joint implant (high performance) arthroplasties performed with (139 joints) and without (31 joints) grommets in 38 patients presenting an average 5.8 years followup. Both groups obtained pain relief, functional motion, stability, and correction of deformity. There was no evidence of particulate synovitis or infection. There were four implant fractures (12.9%) in the nongrommet group, and one (0.7%), because of implant rotation, in the grommet group. Although favorable bone remodeling was observed in both groups, the grommet group showed greater bone preservation at the metaphyseal and midshaft levels and increased intramedullary bone production around the implant stems. The results depend on appropriate surgical staging, meticulous operative and postoperative techniques, severity and progression of disease, and implant durability. The circumferential grommets safely and effectively protect the implant to bone interface to further the durability of implant arthroplasty of the metacarpophalangeal joint.
