Impaction bone grafting for acetabular reconstruction: mean 5.5-year results in Japanese patients.
BACKGROUND
We performed a retrospective outcome study on 23 consecutive acetabular reconstructions involving impaction bone grafting in Japanese patients.


METHODS
Two hips had cavitary defects, and 21 hips had combined segmental and cavitary defects. The mid-term follow-up was performed at a mean of 5.5 years postoperatively. The mean Merle d'Aubigné and Postel hip score had improved from 11.5 to 15.7 points at the final follow-up. Two hips showed migration at 30 months after surgery, and one of these was a candidate for re-revision due to symptomatic cup migration.


RESULTS
The Kaplan-Meier survival rate of the cup, with loosening and re-operation as the end points, was 91.3 and 95.7% at 5 years, respectively.


CONCLUSIONS
Acetabular impaction bone grafting is a reproducible technique in which surgeons should strictly follow the recommended technical procedure.
