title: Improved cementing techniques.
abstract: To obtain good-quality cement, one should follow seven steps: 1. Mix with low frequency. 2. Clean bony cavity to avoid contamination of cement. 3. Pressurize cement before insertion. 4. Insert early, at low viscosity. 5. Pressurize cement after insertion. 6. Fully constrain cement. 7. Use no stress risers. To obtain maximum fixation strength, one should follow four steps: 1. Use gouges to expose trabecular bone. 2. Use brush and lavage to clean bone. 3. Insert cement early at low viscosity. 4. Pressurize cement to force it into open trabeculas. It is fortunate that the steps overlap; they are not mutually exclusive. Both require cleanliness. Both require the use of cement at low viscosity. Both require pressurization of the cement. If the steps are followed it is our belief that the best possible fixation with the best possible cement will be obtained.
