Bone bed preparation

Introduction

Careful preparation of the bone cavity and bone bed with high-pressure pulse lavage and brushing is essential for achieving an effective micro-interlock between the bone and the cement.

Clinical studies have shown that the use of high-pressure pulse lavage reduces the risk of revision due to aseptic loosening.

In the early days syringes and knives were used to clean the bone bed. These tools had the disadvantage of removing healthy tissue along with unhealthy and not sufficiently cleaning the bone bed.

The importance of careful preparation of the bone surfaces, using brushes and pulse lavage to achieve micro-interlock, has been described since the 1970s.
