Supply and demand of bone allograft for revision hip surgery in Scotland.

Overview

The Scottish National Blood Transfusion Service is the main provider of bone for grafting in Scotland. Bone is procured only from live donors, following very strict selection criteria, and we have investigated whether the amount being collected was adequate. Our current harvest of approximately 1700 femoral heads per year is shown not to be enough to meet the future demand for revision surgery of the hip. Many more of these operations are being undertaken, and impaction grafting is being used increasingly. We have calculated the predicted rates of collection and usage for the next four to five years so that we can expand our service in a controlled fashion.
