Abstract

Background: Femoral neck fractures (FNFs) are associated with high mortality and can be treated with arthroplasty or open reduction and internal fixation (ORIF). For basi-cervical FNFs, there is no agreement on which procedure is better. Do arthroplasty and open reduction with internal fixation (ORIF) have different rates of survival? Do age and comorbidities influence survivorship? Hypothesis: Patients who underwent arthroplasty and patients who underwent ORIF have different rates of survival. Patients and methods: Survivorship curves, complications, and hospitalisation length were analysed in 154 patients who received hip arthroplasty, and in 72 patients who received ORIF. Age and ASA score were used to divide the patients into sub-groups and perform secondary analyses. Results: At 4.9 ± 2.4 years after surgery, 74 patients in the arthroplasty group (48%) and 33 in the ORIF group (45%) had died. The survivorship curves of the two groups showed a non-significant difference. The hospitalisation length was 13.5 ± 8.9 days, with a non-significant difference between groups. There were 130 complications in total: 97 in the arthroplasty patients (19 patients had multiple complications, 52 had only one), 33 in the ORIF patients (4 patients had multiple complications, 29 had only one); the odds ratio was therefore 2.1 (p = 0.02). Age, ASA score, Sernbo score, Charlson comorbidity index, and sex (male) were the best predictors of mortality. In the ASA 3–4 sub-group, the survivorship curves showed a lower mortality in the arthroplasty group (p = 0.02). Discussion: Arthroplasty and ORIF are both valid procedures for the treatment of basi-cervical FNFs, but a high mortality rate is associated with either procedures. There is no difference in terms of survivorship between arthroplasty and ORIF in the overall population, but the presence of comorbidities may favour arthroplasty, which should be considered when managing patients with basi-cervical FNFs. Level of evidence: III; retrospective, observational study.
