Acetabular revision in the presence of major bone-stock deficiency is a
difficult clinical and surgical problem. Of an original pool of twenty-four
consecutive patients treated with an acetabular revision with a so-called
jumbo (>65-mm) cementless hemispherical acetabular component, fifteen were
followed for an average of seven years in our previous study. The current
report presents the results for the twelve patients in this group who were
alive at a minimum of twelve years (mean, 13.9 years) postoperatively and
agreed to return for follow-up. The average final Harris hip score was 79
points. No acetabular shell had been revised because of aseptic loosening, and
none was loose as seen radiographically. The complication rate was high but
was largely related to infection. In the patients without infection, the
fixation of these large sockets remained excellent at the time of long-term
follow-up.
