Can introduction of an uncemented, hydroxyapatite coated hemiarthroplasty for displaced femoral neck fractures be recommended?
The role of uncemented fully hydroxyapatite coated hemiarthroplasties for the treatment of displaced femoral neck fractures remains unclear. We investigated if complications, reoperations and mortality differed from that of cemented hemiarthroplasties. The study groups consisted of 78 cemented and 97 uncemented, hydroxyapatite coated hemiarthroplasties with minimum 1 year follow-up. The dislocation rate was 3% in both groups (p=0.84). Proximal femoral fracturing occurred in 1% in the cemented group and in 4% in the uncemented group (p=0.26). Reoperations were performed following 4% of procedures in the cemented group and following 2% of procedures in the uncemented group (p=0.48). Mortality rates did not differ statistically significant between groups. Outcomes were comparable. Introduction of an uncemented hydroxyapatite coated hemiarthroplasty for treatment of displaced femoral neck fractures can be recommended.
