Purpose: Total hip arthroplasty (THA) using dual mobility components (DMC) is a reasonable surgical option for displaced femoral neck fractures in elderly patients, resulting in lower dislocation rates and improved stability. The purpose of this study was to investigate the clinical outcomes and risk factors responsible for mortality in elderly patients who were diagnosed with a displaced femoral neck fracture and had undergone DMC-THA.
Materials and Methods: Out of 147 cases of THA from December 2018 to June 2020, a total of 79 cases were enrolled in this study, with the following characteristics: (1) Garden stage III or IV, (2) over 75 years of age, and (3) over 1 year of follow-up. All the patients received DMC-THA surgery using the anterolateral approach.
Results: The mean follow-up period was 15.0±8.43 months and a total of one dislocation case was observed. The mortality rate was 17.7% (14/79), and it was especially higher in patients with a past medical history of malignancy (odds ratio [OR]=7.18, p=0.03) or a cognitive disorder such as dementia (OR=5.48, p=0.03). Preoperative low initial hemoglobin levels (OR=0.65, p=0.04) and low UCLA (University of California at Los Angeles) score (OR=0.47, p=0.02) were also associated with mortality.
Conclusion: When considering THA as a treatment approach in elderly patients with a displaced femoral neck fracture, a high mortality rate is expected in patients with low preoperative hemoglobin levels or a history of malignancy or cognitive disorders. Hence, thorough monitoring and management should be undertaken before and after surgery.
