What is the best choice for displaced femoral neck fractures in the elderly? Internal fixation or total/hemiarthroplasty.

Two recent meta-analyses of randomized controlled trials were conducted to establish whether total hip arthroplasty was associated with a lower rate of reoperations, mortality, complications, and better function compared to hemiarthroplasty. These metaanalyses showed that patients with displaced femoral neck fractures might benefit from total hip arthroplasty with a lower reoperation rate and higher functional scores. However hemiarthroplasty yielded a lower incidence of postoperative dislocation.[4,5]
