Cemented versus Uncemented Hemiarthroplasty for Femoral Neck Fractures in Patients with Neuromuscular Diseases: A Minimum of 2 Years Follow-Up Study
Abstract Background The aim of this study is to compare the outcomes of cemented and uncemented hemiarthroplasty for femoral neck fractures in patients with neuromuscular disease. Methods We reviewed 156 patients with neuromuscular disease who underwent hemiarthroplasty between 2015 and 2019. Patients were divided into cemented group (n = 105) and uncemented group (n = 51), with a minimum follow-up of 2 years. Factors including preoperative features, duration of surgery, intraoperative blood loss, complications, pain, Harris hip scores (HHS), and quality of life were compared across groups, and Kaplan-Meier curves were used to estimate survival. Results In the uncemented group, the mean duration of surgery was 16.0 minutes shorter (p = 0.001) and the mean intraoperative blood loss was 71.1 mL less (p = 0.01). Visual analog scales (VAS), HHS and European Quality of Life-5 Dimensions (EQ-5D) scores were not different between the groups. Despite a few potential trends, we did not observe a difference in complications such as periprosthetic fractures and dislocations. The rates of mortality were similar between groups (p=0.821). Conclusions Both arthroplasties may be used with good medium-term results in the treatment of femoral neck fractures in patients with neuromuscular diseases.
