ABSTRACT
BACKGROUND:
Xenograft cortical bone is an easy and inexpensive bone graft material, which has good biocompatibility and bio-mechanical properties. As a bone graft, it can function as biological framework for new bone growth and bio-supporting. Moreover, it can also be processed into internal fixation devices.OBJECTIVE:
To review the biological properties, preparation methods and clinical applications of heterogeneous cortical bone for fracture fixation.METHODS:
A computer-based online search of Pubmed database (1990-01/2009-05) and CNKI (1990-01/2009-05) was performed for related articles with key words of "Xenograft cortical bone, Bone graft, Fixation" in English and Chinese.RESULTS ANDCONCLUSION:
A total of 128 articles were collected. Xenograft cortical bone has a good biological performance, in particular, a certain degree of bio-mechanical properties. It is not only able to complete bone filling, bone induction, but also function as internal fixator following processing. However, the traditional preparation process reduces their bio-mechanical properties. Heterogeneous cortical bone can be widely used in intra-articular fractures and cancellous bone fracture fixation, and can be self-absorbed, avoiding the second operation. However, its instability limits its initial mechanical properties of fractures at other sites.
