ABSTRACT
BACKGROUND:
The burden of age-associated fragility fracture of the pelvis has gradually amplified over the years. Commonly used clinical tools cannot fully explain age-associated fracture risk increase, and microstructural analysis could be required to elucidate pubic bone strength decline in elderly. MATERIAL ANDMETHODS:
The study sample encompassed 46 pubic bones obtained from cadaveric donors divided into a young women (<45 years, n = 11), aged women (>60 years, n = 11), young men (<45 years, n = 12) and aged men group (>60 years, n = 12). Micro-computed tomography was used to evaluate the cortical and trabecular microstructure of pubic bone samples.RESULTS:
Apart from age-associated loss in quantitative trabecular parameters, significant alteration of micro-CT parameters that more closely reflect internal trabecular microarchitectural complexity may contribute to pubic bone strength decline in men and women of advanced age (p < 0.05). Additionally, decreased cortical thickness and increased Ct.Po, Po.Dm and Po.N were found in the anterior and posterior cortical surface of pubic bone samples from the aged individuals (p < 0.05). The more pronounced alteration was noted in aged female donors, illustrated in a significant deterioration trend of the Tb.N, Tb.Sp, and thinner posterior cortical surface with decreased pore spacing (p < 0.05).CONCLUSION:
Our data suggest that age-associated deterioration in trabecular and cortical pubic bone micro-architecture could unravel a morphological basis for decreased pubic bone strength and increased pubic bone fragility, which leads to fracture predilection in the elderly women. Thus, the individual fracture risk assessment should be advised in the elderly, with a particular accent on aged women.Palavras-chave
