[Analysis of function and related impact factors after operation of femoral neck fracture for patients aged less than sixty years].
OBJECTIVE
To investigate function and related impact factors after operation of femoral neck fracture for patients aged less than sixty years.


METHODS
In our study,93 patients aged less than sixty years with femoral neck fractures receiving operation from April 2001 to August 2009 and having  complete follow-up data were evaluated in terms of age, sex, co-diseases, side of bone fracture, type of bone fracture (Garden classification), time  between injury and operation, operation procedures, operation time, time in bed, removal internal fixation and function score during follow-up period.  Nonparametric test, rank correlation analysis and Logistic regression analysis were used by SPSS 13.0.


RESULTS
Function scores showed non-normal  distribution. By nonparametric test, the following variable in function scores was of statistic significance:  the Garden classification (H=7.900, P=0.048). By  analysis of correlation, the following variable in function scores was of statistic significance:  Garden classification (rs=0.206, P=0.048). By Logistic  regression analysis, the following variable in function scores was of statistic significance:  Garden classification (P=0.030).


CONCLUSIONS
Hip function  score is of non-normal distribution, and Garden classification is the most important factor influencing the function after operation for femoral neck fracture  for patients aged less than sixty years.
