Texte intégralIn the context of bone health promotion, the aim of this Ph.D dissertation was to analyze potential explanatory factors of the effects of physical activity and of bone geometry on bone mass distribution at the proximal femur in 8-12 year old children. Four studies were undertaken to compare the bone mineral density (BMD) between: (a) the sub-regions of the proximal femur – the neck and its superolateral and inferomedial aspects, the trochanter and the intertrochanter; (b) sexes, concerning the associations/effects of non-targeted physical activity and bone geometry. Sex and regional specific effects of non-targeted physical activity on bone mass distribution at the proximal femur in children were observed. The geometry of the pelvis and the proximal femur, namely the pelvis width and the abductor lever arm, emerged as predictors of bone mass distribution at the proximal femur, therefore as explanatory factors of both the regional and the sex specific patterns. These geometric features might mediate the physical activity effects on bone mineralization at the proximal femur, as long as, when they are considered, the power of physical activity to explain the distribution of bone mass at this skeletal site seems limited.
Resumo : No contexto da promoção da saúde óssea, o objetivo desta dissertação de doutoramento foi analisar potenciais fatores explicativos dos efeitos da atividade física habitual e da geometria óssea na distribuição da massa óssea do fémur proximal, em crianças de 8-12 anos de idade. Para o efeito foram realizados quatro estudos comparando a densidade mineral óssea (DMO) entre: (a) as diversas sub-regiões do fémur proximal - o colo do fémur e os seus aspetos supero-lateral e infero-medial, o grande trocanter e a sub-região intertrocantérica; (b) os sexos, relativamente às associações/efeitos da atividade física habitual e da geometria óssea. Foram observadas associações/efeitos da atividade física habitual na massa óssea do fémur proximal diferenciados quanto ao sexo e sub-região. A geometria da pélvis e do femur proximal, nomeadamente a largura da pélvis e o braço de momento de força dos abdutores, surgiram como preditores da distribuição de massa óssea no fémur proximal e consequentemente como fatores explicativos de diferenciação da distribuição de massa óssea de acordo com o sexo e sub-região. Estas caraterísticas geométricas poderão mediar os efeitos da atividade física na mineralização do femur proximal uma vez que quando consideradas parecem limitar a capacidade explicativa da atividade física na distribuição de massa óssea no fémur proximal.

ABSTRACT Surgical reconstruction of the hip with total joint arthroplasty has proven to be a successful surgical procedure due to the improvements of prosthetic design, biomaterials and surgical technique. However, the success of the surgery it is limited by the mechanical failure of stem loosening. Stress shielding and osteolysis are considered to be the main factors causing loosening. Until now, the influence of stem geometry and fixation modes on stress shielding and bone loss remains controversial. Numerous investigations have been done to examine the stress shielding and adaptive bone remodeling following total hip arthroplasty. All the results have indicated that, in actual applications, the addition to the femur with any stem-type implant would cause certain degree of stress shielding. However, the effects of stem geometry and the bone cement on the degree of stress shielding still remains controversial. To date, although a number of researches have been done on the related topic, however, it lacks an integral approach, an integration of in vitro experiments, simulated stress analyses and clinical evaluations, to examine the above-mentioned problems. This study systematically conducted a tripled approach involving experimental measurement, finite element analysis and clinical follow-up to examine the stress shielding and bone loss following total hip arthroplasty. There are three objectives in this study; the first objective is to investigate the influence of stem geometry (straight or curved) on the degree of stress shielding. The second objective is to investigate the effect of cement in different fixation configurations on the degree of stress shielding, and the third objective is to develop an ideal stemless cevico-trochanteric (C-T) stem to avoid the stress shielding and bone loss that the conventional stem-type prosthesis encountered. In the exploration on the role of stem geometry, the straight (C-fit) and curved (PCA) stems with cementless fixation were examined. Strain measurement was performed using synthetic femur before and after stems insertion, and the surface strains were compared between two groups. Besides, a randomized retrospective analysis was also conducted using Dual-energy X-ray absorptiometry. Periprosthetic bone mineral density for patients who underwent straight and curved stems replacement was measured and compared. In the exploration on the role of cement fixation, C-fit stem implanted with three different configurations of cement fixation (cementless, proximally-cemented and fully-cemented) were compared using finite element analysis. An additional prospective follow-up was also conducted for patients who underwent total hip arthroplasty with C-fit stem by cementless, proximally- and fully-cemented fixations. Finally, in the exploration on the newly designed C-T stemless prosthesis, static tests with strain measurement combined with cyclic tests up to failure were performed to evaluate the mechanical characteristics of this new stemless prosthesis. The results of in vitro test and finite element analysis are well corresponding to those of clinical follow-up. The results indicated that the curved PCA stem induces more stress shielding and causes a more significant bone loss as compared to those of straight C-fit stem. Furthermore, stem implanted with cementless fixation experienced the most significant stress shielding and bone loss as compared to those of either proximally- or fully-cemented. The application of bone cement tends to decrease stress shielding and normalizes the proximal femoral stress. Additionally, the C-T stemless prosthesis exhibited a more physiological stress distribution as compared to those of the traditional stem-type prosthesis. We concluded that, in the six combinations of stem geometry and fixation modes, curved stem combined with cemented fixation would induce the most stress shielding in doing hip replacement. The C-T implanted femur has more physiological strain distribution and satisfactory interfacial bonding with cement fixation.
