MORPHOLOGY OF HUMAN FIBULA / 解剖学报

ABSTRACT

1000 fibulae of Chinese adults were observed and measured. It was found that the angle between the capital articular surface and the long axis of fibula is positively correlated with the circumference of the fibula. In 84.3% among the 1000 specimens, the body of the fibula posesses four borders and four surfaces. It would be more rational, if the nomination of these surfaces were based on their muscle attachments.The average maximum length of the fibula is 340.42?22.76 mm, the smallest circumference is 33.68?4.40 mm, the middle circumference is 39.52?4.99 mm. The caliber index, middle caliber index and the diaphyseal index were calculated respectively. The results obtained show that the side difference as a whole was statistically insignificant, but the diameter at the middle part is an exception. In the paired bones, there are more cases with larger circumference and diameter at the middle on the right side than on the left.According to our observations, some of the relationships between the morphology and function of the fibula were discussed.
