Femoral neck bone adaptation to weight-bearing physical activity by computational analysis.

摘要: Individual differences in bone mass distribution at the proximal femur may be determined by daily weight-bearing physical activity (PA) since self-adapts according to mechanical loads that is submitted. The aim of this study was analyse computationally effect different PA types adaptation femoral neck (FN) analysing regional mineral density (BMD) integral FN and its superior, inferior, anterior posterior subregions. To achieve this, it adopted a 3-D finite element (FE) model coupled with suitable remodeling model. Different were based both on ordinary lifestyle mechanically more demanding as low magnitude impacts (L–I), moderate-magnitude from odd directions (O–I) high-magnitude vertical (H–I). It observed time spent increases, BMD augment around FN, but gain rates between subregions depending hip contact forces; H–I type which structurally most favor superiorly while O–I promoted largest FN. Because these associated uniform spatial they should provide potential basis for targeted PA-based intervention programs improving strength.
