Objective To investigate the risk factors of coxa varus in intertrochanteric fracture patients treated by internal fixation to provide support for treatment and nursing on intertrochanteric fracture.
Methods Total 159 cases of intertrochanteric fracture patients treated by internal fixation from January,2010 to December,2014 in our hospital were retrospectively analyzed.Inclusion criteria:diagnosed as intertrochanteric fractures by imaging;fresh closed fracture;non-pathological fracture or non-other types fracture;conscious and without mental illness.The patients were clinical treated with internal fixation for the treatment and healed at one period.Based on the postoperative varus status,patients were divided into varus group(24 cases) and non-varus group(135 cases).The risk factors questionnaire was made,and patients gender,age,body mass index,bone mineral density,fracture type,internal fixation method,lesser trochanter reseting status,loading time of two groups were selected.The Univariate and Logistic regression analysis were used to analyze the dates.
Results In all 159 cases patients,24 cases were with coxa varus,and the varus rate was 15.1%.Univariate and Logistic regression analysis showed that age,body mass index,bone mineral density,fracture type,small rotor reset,load time were the risk factors of coxa varus in intertrochanteric fracture patients treated by internal fixation.
Conclusion After intertrochanteric fracture fixation,coxa varus is common;and age,body mass index,bone mineral density,fracture type,small rotor reset,load time are the risk factors of coxa varus in intertrochanteric fracture patients treated by internal fixation.
