Prosthesis implantation,bone transplantation,and acetabular revision:Theory and application / 中国组织工程研究

ABSTRACT

BACKGROUND:The main factors that influence revision of acetabular bone defects include evaluation of acetabular bone defects,reconstruction of acetabulum and appropriate acetabular cups used in revision.OBJECTIVE:The review from the three aspects will help to choose an appropriate cup in revision and to formulate the best revision protocols.METHODS:A computer-based online search of PubMed was performed for English articles published from January 1900 to June 2009 with the key words of acetabulum,revision,bone defect,in English and Chinese.Clinical studies published in core periodicals of the latest twenty years were reviewed.Articles regarding primary joint replacement,femoral prosthesis revision and animal experiments were excluded.RESULTS AND CONCLUSION:A total of 61 articles were analyzed,31 were excluded,and 30 mainly published in 5 years,were included.Reconstruction of acetabular bone structure,restoration of original rotation center of hip joint are key factors for repair.Moreover,appropriate prosthesis further benefits the repair effect.Bone transplantation for bone defect and cementedless prosthesis have become favorable methods for revision of acetabular bone defects.
