title: Fit of current glenoid component designs: an anatomic cadaver study.
abstract: The glenoids of 412 scapula specimens were templated with the use of 6 currently available glenoid systems to determine the goodness of fit for the various designs. When a fitting criterion of a mismatch of less than 2 mm between the template and the actual glenoid periphery for 8 radial locations was used, the various designs fit from 0% to 48% of the glenoids. Because glenoid component fixation longevity can depend on the degree of osseous support, these results indicate that glenoid component design and sizing can be improved.
