Densitometric study of the clavicle: bone mineral density explains the laterality of the XXXX .

@entity1 @entity174
INTRODUCTION: Epidemiological studies have shown laterality in @entity174 , such that the left side is more frequently fractured. The present study had the aim of evaluating whether the clavicle on the dominant side is denser and thus explaining the greater incidence of @entity174 on the non-dominant side. MATERIALS AND METHODS: This was a descriptive study on 52 healthy @entity1 , who were classified according to age, sex and whether the dominant or non-dominant side was affected. RESULTS: The @entity1 comprised 28 @entity1 (53.8%) and 24 @entity1 (46.2%). Regarding the dominant side, 30 were right-handed (57.7%) and 22 were left-handed (42.3%). The mean age was 25 years. In this study, it could be seen that the non-dominant side had greater bone mass than the dominant side. It was also observed that the bone density was greater in the middle and distal thirds on the non-dominant side, with a statistically significant difference. In the @entity1 , the density was also greater on the non-dominant side; this difference was not significant in relation to the dominant side, but there were significant differences between the middle thirds (p  <  0.001) and the distal thirds (p  <  0.006). CONCLUSION: Variations in bone density, toward higher and lower bone mass, may have been responsible for the @entity174 . According to the findings from this study, @entity174 occur more in the middle third of the non-dominant clavicle, as a result of greater bone mineral mass, which gives rise to lower flexibility and @entity174 in the region.
