1. Data and methods 1.1 General data The enrolled data were 126 hip fracture patients admitted to our hospital between January 2010 and December 2010, of which 48 were male and 78 were female; age ranged from 65 to 82 years old, with an average of 71.37±9.15 years; 57 were femoral neck fractures and 69 were intertrochanteric fractures; the time from surgery to post-injury ranged from 1 to 72 h. 1.2 Method 1.2.1 Grouping method All patients received surgical treatment in our hospital, and the efficacy of surgery was evaluated at 3 months after surgery, with no deformity of fracture healing, basic recovery of hip function and no pain as excellent; with no deformity of fracture healing, 100-200 degrees of hip mobility loss, intermittent mild pain, and self-care as good; with slight deformity of fracture healing, recovery of hip function If the fracture is healed with slight deformity, the hip joint function is restored to less than 50%, with occasional tolerable pain, walking with crutches, and partial self-care, it is considered as medium; if the fracture is healed with severe deformity, the hip joint function is basically lost, there is continuous pain, and life is not self-care, it is considered as poor. Patients with excellent efficacy assessment results were regarded as the control group, and those with poor efficacy assessment results were regarded as the observation group. 1.2.2 Observation items The general data, comorbidity data, medication and living habits of the patients in both groups were analyzed. The incidence of postoperative complications was also counted, and the complications included pulmonary infection, cardiac events, cognitive dysfunction or exacerbation, urinary tract infection, cerebrovascular events, lower limb deep vein embolism, gastrointestinal stress ulcers, and pulmonary embolism. 1.2.3 Statistical methods Count data were tested by the card method and measurement data were tested by the t-method, all data were calculated using SPSS statistical special software, version number 18.0. 2. Results 2.1 Grouping results The efficacy at 3 months after surgery was assessed as excellent in 28 cases (22.22%), good in 69 cases (54.76%), moderate in 21 cases and poor in 8 cases (6.35%); according to this grouping, there were 97 cases in the control group and 29 cases in the observation group. 2.2 General data comparison results There were statistically significant differences in the proportion of women, age, BMI index, and breastfeeding time in the observation group compared with the control group, P<0.01; there were statistically significant differences in bone density, sunrise rate of living houses and positive family history of fracture in the observation group compared with the control group, P<0.05.
