Parameters Pointing at an Increased Risk for Contralateral Hip Fractures: Systematic Review.

BACKGROUND

Early identification of hip fracture (HF) patients bearing an increased risk for a contralateral occurrence would allow providing preventive measures timely.

OBJECTIVES

To summarize the available evidence describing risk scores, prognostic instruments, or (groups of) parameters predicting contralateral HFs at the time point of the first fracture. Methods/Systematic Review: Articles were identified through searches in MEDLINE and Scopus from inception to April 2014, checking of reference lists of the included studies and reviews. One reviewer assessed all articles for inclusion and abstracted the data. Uncertain cases were discussed and decided with a second reviewer. Salient study and population characteristics were abstracted for each article. Studies reporting the association of a set of risk factors for second HFs were further examined and compared. The number of studies reporting on a risk parameter was assessed.

RESULTS

Searches identified 3560 records, and 47 studies were included in this review. There was a large spectrum of study designs, patient populations, and follow-up periods. Among 11 studies reporting on a set of parameters, female gender was assessed most commonly (7 times), followed by age (5) and parameters of general health, vision, and stroke (each 4 times). We were unable to depict stringent patterns of risk parameters to be used for decision making in clinical practice.

CONCLUSIONS

The findings of this article call for a conjoint effort to achieve an expert consensus regarding a critical set of parameters for a risk instrument identifying patients bearing an increased risk for contralateral HFs early.
