Use of the acetabular reamer to harvest autogeneic bone graft material: a simple method for producing bone paste.

In comparison with solid bone grafts, the particulate form as a paste-like material offers several advantages. The method reported for harvesting a homogeneous mixture of ground cortical and cancellous bone has proven to be simple, time-saving, and productive. A normal acetabular reamer is used to procure the graft from the outer surface of the posterior iliac wing, transforming it simultaneously into paste-like material.
