Effect Of Comorbidities On Postoperative Hip Functions In Patients With Hip Opsteoporotic Fractures

Objective To investigate the effect of common comorbidities in patients with osteoporotic hip fractures on postoperative hip function,and to compare the predicton of postoperative hip function of comorbidity assessment tools,in order to offer a clinical reference to improve outcome.Methods 1.Data of 194 cases of hip fractures(age?65 years,BMD T-score<-1.0)undergoing surgeries from December 2016 to December 2017 in joint ward were collected;2.The comorbidity data were recorded according to three comorbidity assessment tools,3.According to the American Association of Orthopaedic Surgeons(AAOS)Hip and Knee Questionnaire,follow up all patients and quantify follow-up data according to the Hip and Knee Score(HKS);4,The correlation between the comorbidity assessment tools and hip function(HKS)was analyzed.Results 1.Seven comorbidities were associated with postoperative HKS,among which the risk of Parkinson's disease and tumor was relatively high,and the correlation analysis of difference HKS also verified it;2.Parkinson's disease,dementia,cerebrovascular disease and ASA classification were correlated with pre-fracture HKS;3.Among three comorbidities assessment tools,the correlation analysis of ASA classification and postoperative HKS score was the most significant,and the correlation analysis of difference HKS reached the same result.Conclusions For hip osteoporotic fracture patients,seven comorbidities are independent risk factors for postoperative hip dysfunction(Parkinson's disease,tumor,chronic lung disease,dementia,cerebrovascular disease,diabetes and moderate kidney disease);Parkinson's disease,dementia,and cerebrovascular disease are the risk factors for pre-fracture hip function;among the three comorbidities assessment tools,ASA classification is the strongest predictor of postoperative hip function(the higher ASA classification,the worse postoperative hip function will be).
