Uncemented total hip arthroplasty in octogenarian and nonagenarian patients

Uncemented total hip arthroplasty in octogenarian and nonagenarian patients Purpose While uncemented THA has proven benefits over cemented THA, the use of uncemented components in the elderly remains controversial. The purpose of this study was to compare functional outcomes and complication rates of uncemented THA in patients aged > 80 to patients aged < 80, and determine factors that independently influence functional outcomes. Methods The authors evaluated 411 consecutive uncemented THAs at a follow-up of 3.1 ± 0.9 years (range 1.8–5.2), using the Oxford hip score (OHS), EuroQol 5 Dimensions (EQ-5D) score, and noting any complications. The series was divided into two age groups: elderly group (> 80, n = 142) and control group (< 80, n = 269). Uni- and multi-variable regressions were performed to test associations between outcomes and patient age, BMI, American Society of Anaesthesiologists (ASA) score, canal bone ratio (CBR) and canal flare index (CFI). Results The elderly group had femora with higher CBR (p < 0.001) and lower CFI (p = 0.002). The clinical scores were significantly worse for the elderly group, with a higher OHS ( p = 0.039) and a lower EQ-5D score (p = 0.009), but there were no significant differences in overall complications rates ( p = 0.500).

Abstract

Purpose While uncemented THA has proven benefits over cemented THA, the use of uncemented components in the elderly remains controversial. The purpose of this study was to compare functional outcomes and complication rates of uncemented THA in patients aged > 80 to patients aged < 80, and determine factors that independently influence functional outcomes. Methods The authors evaluated 411 consecutive uncemented THAs at a follow-up of 3.1 ± 0.9 years (range 1.8–5.2), using the Oxford hip score (OHS), EuroQol 5 Dimensions (EQ-5D) score, and noting any complications. The series was divided into two age groups: elderly group (> 80, n = 142) and control group (< 80, n = 269). Uni- and multi-variable regressions were performed to test associations between outcomes and patient age, BMI, American Society of Anaesthesiologists (ASA) score, canal bone ratio (CBR) and canal flare index (CFI). Results The elderly group had femora with higher CBR (p < 0.001) and lower CFI (p = 0.002). The clinical scores were significantly worse for the elderly group, with a higher OHS ( p = 0.039) and a lower EQ-5D score (p = 0.009), but there were no significant differences in overall complications rates ( p = 0.500).
