Use of Jumbo Cups for Revision of Acetabulae with Large Bony Defects

Several methods of treatment are available for acetabular revision associated with bone loss. Hemispherical components are preferred for most acetabular defects. Jumbo cups (minimum diameter of 62 mm in women, 66 mm in men, or 10 mm larger than the normal contralateral acetabulum) are often useful for large defects. The purpose of this study is to report a large jumbo cup series with an average 10-year follow-up.
