ABSTRACT
Introduction: In long bones including radius, surface opening of nutrient canal is known as nutrient foramen, which transmits nutrient artery to supply cortical bone and medullary cavity. Topographical information about nutrient foramen is very crucial during various orthopedic surgical procedures. Objective: Present study was conducted to study number of nutrient foramina, its location and direction in relation to growing end of bone and to calculate foraminal index of human radius. Subjects and Methods: In present study 63(31 right and 32 left sided) radii bone of unknown age and sex were studied. Only fully intact bone without any disease were included. Surface location and direction of nutrient foramina were recorded. Total length of radius was measured with osteomatric board. Distance of nutrient foramen from proximal end was measured with digital vernier caliper. And foraminal index was calculated. All data was tabulated and analyzed statistically. Results: All radii had single nutrient foramen. Majority (82.54%) of the nutrient foramina were detected on the anterior surface, 14.29% were on posterior surface and only two bone have nutrient foramen on other surface. Zone I contained 30.16% and Zone II contained 66.67% and Zone III contained 3.17% foramina. Direction of all foramina were towards upper end of radius except two bones. Conclusion: Almost all the results coincided with previous studies from different geographical regions. Thorough knowledge of morphology of nutrient foramina is necessary for preserving circulation. Because it is very crucial in bone grafting, fracture healing, joint replacement therapy and vascularized bone micro surgeries.
ABSTRACT
Introduction: Nutrient foramen is an opening into shaft of fibula which gives passage to the blood vessels of medullary cavity. The knowledge of nutrient foramen is important in surgical procedures like bone grafting and more recently in microsurgical vascularized bone transplantation. Objective: To determine the number, location and direction of nutrient foramen and whether the nutrient foramens obey the rule of ossification, that is directed away from the growing end of the bone or not. Subjects and Methods: The present study consisted of 150 (75 right and 75 left) dried fibula bones excluding any fracture or pathological abnormalities Number and direction of nutrient foramen was observed in each fibula. Location of nutrient foramen in relation with surfaces and zones of fibula was determined. Results: It has been observed that 96.67% of the fibula had a single nutrient foramen, 3.33% double foramen and no bone had 0 nutrient foramen. It was concluded that 98.71% of the nutrient foramina were present on the posterior surface and 1.29 % on medial crest. It was also concluded that most (98.06%) of the foramina present in the zone II followed by zone III (1.29%) then by zone I (0.65%). All foramina were directed toward the upper end of fibula. Conclusion: By knowing the number and location of the nutrient foramina in fibula would be useful in preventing intra-operative injury of nutrient artery during orthopedic, plastic and reconstructive surgery and will also be relevant in medico legal practice.
ABSTRACT
Introduction: The identification of sex in human skeletal remains is an important component of manyanthropological investigations and forensic science. Sex determination using sacrum is often considered withvarious available parameters and indices when dealing with human skeleton remains. Sacral index is the mostimportant criteria for sex determination using sacrum. Present study aims at determining the significance ofsacral index in sex determination from sacra of saurashtra region.Materials and Methods: 120 (84 male and 36 female) adult human sacra of known sex from Saurashtra regionwas included in present study. Ventral straight length and maximum breath of sacrum was measured , sacralindex calculated, Demarking points for these parameters were used for identification of sex of sacrum.Results: In males sacral index varies from 90.38 to 119.36, with mean value of 103.49 and standard deviationwas found to be 8.52. In females sacral index varies from 92.86 to 141.33, with mean value of 116.97 andstandard deviation was found to be 8.52. In statically significant range(Mean ± 3 SD) maximum value of malesacral index was 121.76 and minimum value of female index was 91.40. These two points were accepted asdemarking points.Conclusion: Significant differences has been observed in the sacral index of males and females of Saurashtraregion. Sacral index is higher in females than in males. On the basis of present study it can be concluded that inSaurashtra region sacrum having sacral index less than 91.40 is definitely of male whereas sacrum havingsacral index more than 121.76 is definitely of female. However not a single parameter could identify sex of 100%of the bones.
