Literature suggests that the tibia is highly susceptible to longitudinal stress fractures; however, such fractures also occur in the femora
but less commonly in fibula.
There were no statistical differences between the right and left femora
, the averaged data of right and left sides were used in statistical analyses.
Results: Out of 211 femora
, right and left side distribution was 103 (48.8%) and 108 (51.2%) respectively.
Fore and mid legs yellow except coxae and trochanters black, femora
blackish with yellow tips, and tarsomere 5 brown; hind leg black except tarsus dark yellow with tarsomere 5 dark brown.
The statistics analysis also revealed significant differences in dimensions between male and female femora
, indicating that distinguished designs for the genders may be required to improve bone-implant fitness as discussed in the femoral fixation devices.
Body shining black; scape, pedicel, ring segment, first funicular segment, all tarsi, bases and apices of fore and mid tibiae, and bases and apices of fore and mid femora
dark brown; mid region of fore tibia, fore femora
, mid tibia and mid femora
liver brown; hind femur light brown; hind tibia liver brown with apex testaceous; eyes transparent (dirty white) with small blackish spots; Forewing hyaline (transparent) with veins pale brown.
Color on femora
light ventrally with indistinct markings above, dark annuli on other segments.
This study is an attempt to examine the sexual dimorphism in femora
of Indian origin.
were observed for the number of nutrient foramina in each bone.
Diameter of medullary cavity of left femora
was taken by using linear micrometer.
In the whole series of 100 femora
examined, we have found total number of 159 foramina including both dominant and secondary.
Dorsal margins of fore and middle femora
slightly curved, ventral margin nearly straight; the greatest width of mid-femur slightly wider than width of visible parts of tegmina, proportion 1:0.75-0.85.
