Survival and radiographic analysis of a glenoid component with a cementless fluted central peg

Background c loosening of glenoid components is a common problem associated with total shoulder arthroplasty and one cause for failure. A new cementless fluted glenoid component was developed and has shown excellent bony ingrowth in a canine model. esis al utilization of this cementless fluted pegged glenoid component in total shoulder arthroplasty would lower rates of radiolucent lines and aseptic loosening. als and methods n January 2005 and December 2007, 83 primary shoulder arthroplasties with a minimum of 2 yearsʹ follow-up were performed with the uncemented fluted pegged glenoid component. Radiographs and records were reviewed to determine stability and survival of the glenoid component. s mentless fluted pegged glenoid components had survived at the most recent clinical follow-up. Radiographs showed no evidence of component loosening or radiolucent lines. Evidence of fingerlike projections of bone between the flanges of the implant was found in 24 cases (29%). sions ntless fluted pegged glenoid component showed excellent initial clinical survival and integration. Further studies regarding continued durability of this component appear warranted.
