Abstract:

BACKGROUND: With the faster development of biomechanics and computer simulation technique, treatments for femoral neck fracture main concentrate on internal fixation, muscle pedicle bone, bone flap, and periosteum implantation, as well as prosthetic replacement under the guidance of computer.
OBJECTIVE: To analyze the stress distribution in the neck of femur through morphological, biomechanical analysis, and computer simulation technique of reviewed treatments for femoral neck fracture.
METHODS: “Femoral neck fracture” in English was utilized as search terms to retrieve Pubmed database (1999-01/2009-06). Simultaneously, “femoral neck fracture” in Chinese was used to search Wanfang database (1999-01/2009-06). Literatures were limited to English and Chinese languages. The femoral neck research equipment and studies for cure of femoral neck fracture were included, while other outdated and repetitive researches were excluded.
RESULTS AND CONCLUSION: Totally 667 literature were obtained from the computer screen, and 42 documents of them were involved for analysis according to the inclusion and exclusion criteria. In case of femoral neck fracture analysis method, scholars in China and abroad have carried out extensive studies, including: ①Using CT scan for the form of femoral neck to generate CT image, the study obtains Results Feature data with finite element analysis. Meanwhile, results Feature data could reconstruct a 3D body by the software. ②Biomechanical analysis for stress distribution about the femoral neck could obtain corresponding data. ③Conclusion of such analysis could be applied to the treatment of femoral neck fracture, especially for the aged
