Abstract

Objective:To compare the outcomes of elderly patients with nondisplaced and minimally displaced femoral neck fractures treated with internal fixation versus arthroplasty.Data Sources:A comprehensive search of the MEDLINE, Embase, and central databases was conducted through June 25, 2019.Study Selection:Studies were included if the sample population was (1) 60 years of age or older, (2) had nondisplaced or minimally displaced (Garden I or II) femoral neck fractures, and (3) if the study compared internal fixation versus arthroplasty. Only full-text English manuscripts were included. The primary outcome was reoperation. Secondary outcomes included mortality, patient-reported outcomes, length of hospital stay, infection, and blood transfusions.Data Extraction:Two authors independently extracted data from the included studies. Each study was independently evaluated for quality using the Cochrane risk of bias assessment.Data Synthesis:Of the 1597 identified articles, 4 manuscripts met the eligibility criteria with a total of 579 patients (236 treated with hemiarthroplasty and 343 treated with internal fixation). Patients treated with arthroplasty had a significantly lower risk of reoperation when compared with those treated with internal fixation [relative risk: 0.30 (95% CI, 0.16-0.55, P < 0.01)]. There was no significant difference detected in 1-year mortality risk between the 2 treatment groups.Conclusions:In elderly patients with nondisplaced and minimally displaced femoral neck fractures, treatment with hemiarthroplasty may reduce the relative risk of reoperation by 70% when compared with internal fixation.Level of Evidence:Therapeutic Level III.
