The effect of genetic variance on fracture healing as assessed by callus composition and strength

Wulff, Alexander Christopher 08 April 2016 (has links)
Bones have a large capacity for repair and regeneration after an injury. 5-10% of the nearly 8 million fractures that occur every year in the United States do not heal properly. Bone repair and regeneration is a complex process that utilizes molecular and cellular interactions to return to its original structure. Phosphate is essential for healthy bone growth and when phosphate deficient it has been shown to impair the process of fracture healing. It is unknown if replenishing phosphate to the diet will help return the injured bone to its original properties. Some of the differences in fracture repair may be due to genetic variability that contributes to morphology of bone and fracture healing. This study was carried out to assess how genetic variability affects the process of fracture healing. To determine how genetic differences interact with phosphate deficiency fractures were generated in three different inbred mouse strain (A/J (AJ), C57BL/6J (B6), C3H/HeJ (C3)) that had previously been shown to have different endochondral bone formation. Animals were placed on a phosphate restricted diet two days prior to fracture, and was maintained for 15 days, which covered the normal duration of endochondral bone development. To determine if replenishing phosphate in the diet could recover the normal healing, phosphate was returned to the diet after 15 days. There was also control groups that were on a regular diet for the entire time of the study, which was used for comparison. Micro-computed tomography (micro-CT), biomechanical torsion testing, and contrast enhanced micro-computed tomography (CECT) were methods used to asses the properties of the callus over the course of fracture healing. Micro-CT and mechanical test results showed that there were significant differences within AJ, B6, and C3 strains of mice at the various post-operative day (POD) time points. Results from micro-CT data showed that as the POD time point increased there was an increase in the amount of mineralized tissue and a decrease in fracture callus. These results were confirmed by with the increase in strength measurements from mechanical testing conclusions. Further, the fracture callus is less rigid at the early time points and as the fracture callus becomes mineralized there is an increase in the rigidity measures. Other measures of mechanical properties showed that there were significant differences in the B6 and C3 strains of mice among the various POD time points and control and phosphate restricted diets. Assessing cartilage content via CECT showed that there were significant differences in the control and phosphate restricted diets at POD 14, however many of these differences were recovered at the later time points. Visualization of the fracture callus using CECT confirmed that there was diminishing cartilage present in the fracture callus. These results provide insight into the fracture healing process and much information about the return of stability and strength to the fractured bone. Taken together, the outcomes of this study indicate that the bones heal and mechanical strength is recovered once the phosphate has been added back into the diet.

Avaliação de fatores relacionados ao tratamento da classe II com aparelho de Herbst /

Ravelli, Taísa Boamorte. January 2017 (has links)
Orientador: Ary dos Santos Pinto / Resumo: O objetivo deste estudo é avaliar as alterações dento esqueléticas induzidas pelo uso do aparelho de Herbst em indivíduos com má oclusão classe II divisão 1ª de Angle levando em consideração fatores de relevância clínica sobre o uso deste aparelho. A amostra foi constituída de telerradiografias cefalométricas em norma de 45° de arquivo que foram divididos em de 4 grupos: o grupo 1 (tratado) constituído de 25 indivíduos (lados direito e esquerdo), com idade entre 8 e 10 anos, tratados com Herbst de ancoragem tipo bandado. O grupo 2 (tratado) constituído de 34 indivíduos, com idade entre 14 e 18 anos, tratados com Herbst de ancoragem tipo bandado. O grupo 3 (tratado) constituído de 12 indivíduos, com idade entre 14 e 18 anos, tratados com Herbst de ancoragem tipo splint metálico. O grupo 4 (controle), utilizado para comparação, constituído de 23 indivíduos de 14 a 18 anos, de ambos os gêneros, não tratados ortodonticamente, com características semelhantes ao grupo experimental 2 e 3, derivados do Burlington Growth Centre da Faculdade de Odontologia da Universidade de Toronto, Canadá. Foi observado efeito da fase de maturidade, efeito do tratamento com ancoragem splintado e efeito de diferentes sistemas de ancoragem. Houve diferenças dentárias e esqueléticas quando se tratando em diferentes fases de maturidade; houve também maior efeito dentário quando se comparando com grupo controle; e não houve grande significância no tratamento considerando as diferentes formas de ancoragem. / Abstract: The objective of this study is to evaluate dental skeletal changes induced by the use of Herbst appliance in Class II individuals taking into consideration relevant clinical factors concerning the use of this appliance. The sample was constituted of oblique radiographies taken from archives and were divided into 4 groups: group 1 (treated) with 25 individuals (right and left side), age between 8 to 10 years, treated with Herbst with banded anchorage. Group 2 (treated) with 34 individuals, age between 14 to 18 years, treated with Herbst with banded anchorage. Group 3 (treated) with 12 individuals, age between 14 to 18 years, treated with Herbst with splinted anchorage. Group 4 (control) used for comparison, with 23 individuals between 14 to 18 years, both genders, not treated orthodontically, with similar characteristics to experimental groups 2 and 3, taken from Burlington Growth Centre from Dentistry Faculty, University of Toronto, Canada. It was observed phase of maturity effect, splint metallic treatment effect and different anchorage system effect. There was dental and skeletal differences when treating in different maturity phase, there was also more dental effects to splint metallic treatment and there was no significant difference when treating with two anchorage types. / Doutor
