Abstract:

BACKGROUND: Various methods have been reported for the repair and reconstruction of long bone segmental defect, but all of them have different advantages and disadvantages which limit their wide application. And this still presents as a huge problem for many orthopaedics.
OBJECTIVE: To review the latest research on reconstruction and repair of long bone segmental defects at national and international level.
METHODS: A computer-based retrieval was conducted in PubMed database, CNKI database and VIP database by the first author for the articles published from January 1990 to December 2012, on the repair and reconstruction of long bone segmental defect with the key words of “bone defect, long bone reconstruction, tissue engineering of bone, scaffolds, bone reconstruction, bone graft, bone tumor, tumor resection, musculoskeletal tumors, regeneration, autografts” in English and “large segment, bone defects, bone tumors, soft tissue tumors, tumor resection, tissue engineering, bone graft” in Chinese. A total of 104 articles were screened out, and finally, 52 articles were included for further research.
RESULTS AND CONCLUSION: Traditional method for the repair of long bone segmental defect includes autologous or allogeneic bone graft, bone lengthening and artificial prosthesis replacement. The development of prosthesis that was suitable for child limb salvage and consistent with the child growth characteristics has become the challenge to child limb salvage. In order to solve the problem, we designed the prosthesis that can continuously extent, and applied for the limb salvage reconstruction of tumor. With the development of medical technology, all kinds of artificial bone, especially bone tissue engineering and gene treatment are being gradually used to repair bone defect, which will further enhance the clinical evaluation of bone defect repair, and that is the direction of further research.

Key words: bone neoplasms, extremities, transplantation, autologus, prosthesis implantation
