Aim: To develop a device to improve the preparation of morcellised bone graft for use in revision arthroplasty surgery.

Background: Washing morcellised graft prior to impaction has been shown to improve the stability of the graft after impaction. By removing the cellular debris the chance of contamination is potentially reduced.

Methods: A readily available domestic appliance was identified which met the requirements of being able to contain the graft whilst allowing free drainage of the pulsed lavage solution. This hand held potato masher has an all metal construction with few moving parts and is therefore easily cleaned and sterilised between cases. The numerous perforations in the receiver of the masher ensure that the lavage solution rarely backs up and also that all of the cellular debris is washed through effectively.

Results: This device has been in regular use in this institution over the last two years. It allows a no touch technique for the preparation of morcellised graft in complex cases that require replacement of the bone stock.

This poster will demonstrate pictorially the technique for graft preparation and the quality of the prepared graft that can be obtained.
