Effect of component design in retrieved bipolar hip hemiarthroplasty systems.
Primary articulation of bipolar hemiarthroplasty systems is at the femoral head-liner interface. The purpose of this study was to compare observed damage modes on 36 retrieved bipolar systems with implant, demographic, intraoperative, and radiographic data to elucidate the effects of component design, specifically locking mechanism, on clinical performance. Retrieved bipolar hip hemiarthroplast...
متن کاملComparison of bipolar hemiarthroplasty and total hip arthroplasty for displaced femoral neck fractures in the healthy elderly: a meta-analysis
BACKGROUND Displaced femoral neck fractures (FNFs) in healthy elderly patients have traditionally been managed with hemiarthroplasty (HA) or total hip arthroplasty (THA), with studies suggesting that THA may be the better option. However, it has recently been reported that bipolar HA (BHA) also provides good outcomes, and it is not clear as to whether BHA or THA is most appropriate. The purpose...
متن کاملUnipolar Versus Bipolar Hemiarthroplasty for Displaced Femoral Neck Fractures in Elderly Patients.
Hip replacement using hemiarthroplasty (HA) is a common surgical procedure in elderly patients with femoral neck fractures. However, questions remain regarding the choice of unipolar or bipolar HA. A meta-analysis of randomized, controlled trials (RCTs) was performed to determine whether bipolar HA was associated with lower rates of dislocation, reoperation, acetabular erosion, mortality, and g...
متن کاملUnipolar versus bipolar uncemented hemiarthroplasty for elderly patients with displaced intracapsular femoral neck fractures.
PURPOSE To compare outcomes of unipolar versus bipolar uncemented hemiarthroplasty and determine factors affecting outcomes. METHODS 433 and 274 elderly patients with displaced intracapsular femoral neck fractures underwent uncemented unipolar hemiarthroplasty and uncemented bipolar hydroxyapatite-coated hemiarthroplasty, respectively. Surgical options were based on the patient's general cond...
متن کاملTotal hip arthroplasty versus hemiarthroplasty for displaced femoral neck fractures: meta-analysis of randomized trials.
BACKGROUND Most patients with displaced femoral neck fractures are treated by THA and hemiarthroplasty, but it remains uncertain which if either is associated with better function and lower risks of complications. QUESTIONS/PURPOSES We performed a meta-analysis of randomized controlled trials (RCTs) to determine whether THA was associated with lower rates of reoperations, mortality, complicat...
