简要总结
Periprosthetic joint infections (PJI) following hemiarthroplasty for hip fractures are a catastrophic complication that results in severe worsening of patients' daily function and quality of life. The incidence of prosthetic joint infection (PJI) in hemiarthroplasty after femoral neck fracture varies from 2% to 17%. Identifying risk factors associated with early infection following HA for hip fractures may provide an opportunity to treat and prevent this potential complication with preoperative planning in many patients. So investigators will study the rate of early infection and its associated factor after bipolar hemiarthroplasty.
详细描述
Femoral neck fractures (FNF) have a significant incidence and a rising trend worldwide. FNF is associated with a high mortality and disability rate, decreasing the independence and quality of life for affected patients. Acute displaced intracapsular femoral neck fractures account for about half of all hip fractures, with the majority of these fractures in older patients being treated surgically with hip hemiarthroplasty(HA), total hip arthroplasty, or internal fixation. Hemiarthroplasty is also used to treat femoral neck nonunion, failed screw fixation, and pathological femoral neck fracture. The treatment aims are to reduce pain, allow early mobilization, and restore the patient's pre-injury level of function while limiting perioperative surgical and medical complications. Patients with FNF frequently undergo hemiarthroplasty to restore joint biomechanics. Two types of implants are used in hemiarthroplasty: monopolar and bipolar . The bipolar implants have a polyethylene bearing between the stem and head of the endoprosthesis, which allows the components to rotate. There are debatable findings and a lack of consensus on the optimal component for hemiarthroplasty. Periprosthetic joint infections (PJI) following hemiarthroplasty for hip fractures are a catastrophic complication that results in severe worsening of patients' daily function and quality of life. The incidence of prosthetic joint infection (PJI) in hemiarthroplasty after femoral neck fracture varies from 2% to 17%. Identifying risk factors associated with early infection following HA for hip fractures may provide an opportunity to treat and prevent this potential complication with preoperative planning in many patients. So investigators will study the rate of early infection and its associated factor after bipolar hemiarthroplasty.

结局指标
主要结局
incidence of early infection after bipolar hemiarthroplasty
时间窗: 4 weeks postoperative
investigators will take all cases with bipolar hemiarthroplasty after femoral neck fracture then follow up them for 4 weeks. An infection was categorized as early, if it occurred within 4 weeks after surgery After that investigators will classify them to infected (disease group) and non infected (control group) and studying risk factor predisposing to early infection after HA. For diagnosis of infection : the presence of persistent discharge after 7 days
risk factor predisposing to early infection after HA.1-preoperative parameters :sex
时间窗: preoperative evaluation 1 week
male or female
risk factor predisposing to early infection after HA.1-preoperative parameters : • Distant septic focus after arthroplasty as (pneumonia ,UTI ,abdominal ,oral and cutaneous infection).
时间窗: preoperative evaluation 1 week
present or no
risk factor predisposing to early infection after HA.1-preoperative parameters : • Active skin disease (at site of surgical incision)
时间窗: preoperative evaluation 1 week
present or not
risk factor predisposing to early infection after HA.1-preoperative parameters : • Smoking and alcohol consumption
时间窗: preoperative evaluation 1 week
yes or no
risk factor predisposing to early infection after HA.1-preoperative parameters :Patient age
时间窗: preoperative evaluation 1 week
Age in years
risk factor predisposing to early infection after HA.1-preoperative parameters :Chronic diseases as Diabetes, rheumatoid arthritis and other inflammatory or autoimmune arthritis.
时间窗: preoperative evaluation 1 week
present or not
risk factor predisposing to early infection after HA.2-intraoperative parameters :• Appropriate antibiotics prophalyxis and Need to blood transfusion.
