Abstract
Background
Revision hip arthroplasty for excessive bone loss because of osteolysis or infection is difficult theme. Bone grafting is essential technique for bone loss and need of allograft is increasing. Recently, many hospital bone banks are established in Japan. The aim of this study is investigate efficacy and safety of allograft in our hospital bone bank.
Material and method
We evaluated management, result and complication of allografts retrieved from living donors in our institute.
Result
All donors meet the criteria of Japanese Orthopaedic Association (JOA) guideline and gave fully informed written consent. We obtained 75 femoral head grafts that were retrieved during primary total hip arthroplasty under sterile operating theatre conditions. No donor had hepatitis B and C, human immunodeficiency (HIV), Human T-cell leukemia (HTLV-1) and Syphilis. After heat treatment, allograft was swabbed for cultures and stored in freezer at −80□. All cultures ware negative and proved before implantation. We used allograft in 27 revision hip arthroplasty. Six cases were femoral side and 21cases were acetabular side. At the minimum of 3 months follow-up, 1 fracture of acetablar and 1 superficial infection occurred. No allergic reaction happened.
Conclusion
Our bone bank thoroughly managed based on JOA guideline was effective and safe. Careful follow-up is needed for long-term implant fixation and osteoinduction.
