Summary

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.

Detailed description

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.
