Abstract:

BACKGROUND: Although bone mineral density can diagnose osteoporosis, it cannot reflect the existing bone metabolism of the subjects; bone turnover markers cannot diagnose osteoporosis, but it can timely reflect the current bone turnover rate of the subjects.
OBJECTIVE: To summarize osteoporotic fracture risk predicted by bone turnover markers and bone mineral density, and to theoretically analyze the feasibility of fracture healing after operation.
METHODS: With bone turnover, biochemical marker, osteoporosis in English for the search terms, Pubmed database from January 1999 to January 2009 was retrieved; With bone turnover, bone metabolism, biochemical markers, bone mineral density, osteoporosis, fractures in Chinese for the search terms, CNKI database from January 1999 to January 2009 was searched. Literatures were limited to English and Chinese languages. Inclusive criteria: the article closely related to predict fracture risk with bone turnover markers and bone mineral density; Exclusive criteria: duplicated documents.
RESULTS AND CONCLUSION: Totally 631 literatures were screened out by computer, according to inclusion and exclusion criteria, 31 documents of which were involved for analysis. Osteoporosis is one of the main causes of elderly disease and death. Early prediction of osteoporotic fracture risk has a great significance. This article describes the bone metabolism, the type of bone biochemical markers, bone mineral density measurement, multi-cell basic unit and the OPG-RANKL-RANK system in bone reconstruction after a long-term fixation; focuses on the use of bone turnover markers and bone mineral density to prognosticate the fracture risk in osteoporosis or after long-term fixation by domestic and foreign academician, and theoretically analyze the feasibility of predicting postoperative fracture healing.
