| Objective: To discuss risk factors for the periprosthetic fracture after hip arthroplasty and provide reference for clinicians' diagnosis and treatment.Methods: Potential studies were searched in databases including Pubmed,Embase,Cochrane Library,CNKI as well as Wanfang Database up to November 2018 and references in related literature.The methodological quality of literature was estimated by Newcastle–Ottawa Scale.Raw data were merged and tested mainly by Revmain5.3.Results: There were 17 studies appropriate with 90 632 patients.The results revealed that it increased the risk of periprosthetic fracture after hip arthroplasty,including female sex(OR=1.62,95%CI:1.44-1.82,P<0.01),revision(OR=3.78,95%CI: 1.88-7.58,P<0.01),preoperative diagnosis of rheumatoid arthritis(OR=1.60,95%CI: 1.07-2.37,P=0.02).Conversely,patients involved with cemented prosthesis fixation(OR=0.43,95%CI: 0.27-0.68,P<0.01)were less likely to suffer periprosthetic fracture after hip arthroplasty.The relationship between developmental dysplasia of the hip and periprosthetic fracture in hip replacement needs more high-quality studies to confirm.Other factors were not significantly relevant to periprosthetic fracture after hip arthroplasty,consisting of age whether over 50 years old or not,concomitant heart diseases and American Society of Anesthesiologists?3.Conclusion:Orthopedics doctors should be constantly on the alert for the risk factors including female sex,revision and rheumatoid arthritis.They are supposed to prevent the periprosthetic fracture after hip arthroplasty by gentle action in operations and closely instructing patients in functional exercise after operations when the above risk factors occur.The fixation of cement prosthesis is a protective factor for hip replacement complicated with periprosthetic fracture. |
