Cemented versus uncemented hemiarthroplasty for femoral neck fractures in patients with neuromuscular diseases: a minimum of 2 years’ follow-up study

BACKGROUND: The aim of this study was 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 June 2015 and December 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 min. 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.
