BONE BANKING, CURRENT PRACTICE AND FUTURE PROSPECTS

Abstract

Bone grafting is used extensively in orthopaedic reconstructive surgery. Revision hip arthroplasty often presents surgeons with difficult bone loss problems, which can sometimes be addressed using donated bone. This need for bone graft has increased in recent years with greater numbers of joint replacements and increasing life expectancy after replacement, particularly as prostheses are being implanted into younger patients. Current practice of bone banking involves careful donor selection, stringent screening tests and internal safety systems in bone banks to prevent the ever present threat of communicable diseases. Introduction of strict monitoring systems to prevent allograft-related diseases has rendered a significant number of primary hip replacement patients unsuitable for bone donation. This study audited the practice of bone banking at Portsmouth Hospitals NHS Trust to look into various factors responsible for exclusion of patients from bone banking. All 55 patients underwent screening in pre-operative assessment clinics using standard Proforma to assess their suitability for femoral head donation during the course of their primary hip replacement surgery. After the initial screening stage 33 patients (60%) were excluded due to variety of reasons. The majority of those excluded (23 patients) were not accepted as donors because of their potential risk of transmission of disease to the recipients. The situation is likely to become worse in future as the incidence of communicable diseases is rising in the UK. Alternative sources of bone grafts should be explored in future to meet the demands for, example auto-banking.
