ABSTRACT
Objective To investigate and analyze risk factors of re-fracture after operation of osteoporotic hip fracture.Methods Two hundred forty-seven patients receiving operation of osteoporotic hip fracture were retrospectively studied and followed up,and all patients were divided into re-fracture group (54 patients) and no-re-fracture group (193 patients).The related factors such as sex,age,body mass index (BMI),affected side,initial fracture site,operation type,perioperative blood loss,postoperative delirium,postoperative bedridden time,medical complications,Charlson comorbidity index,antiostoporosis therapy,hip function scores with Harris and functional independence measurement (FIM) scores were compared by single factor analysis and multivariate Logistic regression analysis.Results Single factor analysis and multivariate Logistic regression analysis both showed that the risk factors of re-fracture after operation of osteoporotic hip fracture included age,postoperative delirium,hypertension,diabetes mellitus,cerebrovascular disease,antiostoporosis therapy,hip function scores with Harris and FIM scores (P ＜ 0.05 or ＜ 0.01).Conclusions Risk factors of re-fracture after operation of osteoporotic hip fracture include passive factors of age,postoperative delirium and medical complications,and subjective factors of antiostoporosis therapy,hip function scores with Harris and FIM scores.Patients should receive medical treatment positively,enhance antiostoporosis therapy and rehabilitation training of hip function to prevent re-fracture.
