Abstract
Stable fixation with macro and micro interlock prevents early migration and therefore early failure of cemented acetabular cups.
The authors describe a cementation technique in an in-vitro model that increases the interossoeous pressure by a factor of 3.5 in the ishium, 4.5 in the ilium and 5.1 in the pubis by the injection of the cement directly into the 10 mm key holes prior to insertion of the cement bolus and cup.
The abstracts were prepared by Mr D J Bracey, Editorial Secretary. Correspondence should be addressed to him at Royal Cornwall Hospital, Treliske, Cornwall TR1 3LJ, England.
