Fractures around femoral prosthesis after artificial hip replacement / 中国组织工程研究

ABSTRACT

BACKGROUND:With the wide application and in-depth research of artificial hip joint, more secondary fractures around femoral prosthesis are reported. OBJECTIVE:To investigate the reasons, preventive measures, classification and treatment method of fractures around femoral prosthesis after artificial hip replacement. METHODS:The clinical data of the type classification, treatment method and clinical efficacy of fractures around femoral prosthesis after artificial hip replacement were retrospectively analyzed. The multi-level study was performed to investigate the trend of the relevant literatures. According to the Vancouver classification criteria, the various types of fractures and the results and complications of various treatment methods were analyzed, the treatment methods of different fractures were identified, and the effective and objective evaluation criteria were established to provide references for the clinical treatment. RESUTLS AND CONCLUSION:The fractures around femoral prosthesis after artificial hip replacement were closely related with the age of the patients, basic diseases, osteoporosis and selection of prosthesis type. The Vancouver classification criteria and treatment programs have guiding significance to the clinical efficacy. The fractures should be treated with different methods according to the different types in order to promote the fracture healing. The fractures around femoral prosthesis after artificial hip replacement were commonly treated with shape memory alloy embracing fixator, minimal y invasive fixation system, locking compression plate, al ograft cortical bone plates, carbon fiber, impaction bone grafting and renovation. In the practice application, various methods are often used in combination. For the patients with B2 and B3 type fractures, we should pay attention to the bone grafting around the fractures and the inner and outer medul ary cavity.
