ABSTRACT

Background: Nutrient foramen is an opening into shaft of humerus which gives passage to the blood vessels ofmedullary cavity. The knowledge of nutrient foramen is important in surgical procedures like bone grafting andmore recently in microsurgical vascularized bone transplantation. Lack of an adequate vascular supply cansignificantly delay or prevent fracture healing. Nutrient artery is the major source of blood supply to the longbone and hence plays an important role in fracture healing.Objective: The nutrient foramens obey the rule of ossification, that is directed away from the growing end of thebone or not.Materials and Methods: The present study consisted of 68 (34 right and 34 left) dried humeurus excluding anyfracture or pathological abnormalities. Number and direction of nutrient foramen was observed in each humerus.Location of nutrient foramen in relation with surfaces and zones of humeurus was determined.Result: It has been observed that 94.12% of the humerus had a single nutrient foramen, 6.39% double foramen,all humerus have nutrient foramina. It was concluded that the majority (73.61%) of the nutrient foramina werepresent on the antero-medial surface, 8.33% on the anterolateral surface and 8.33% on the posterior surface ofthe shaft of humerus and 8.33% of nutrient foramina present on anterior border. It was also concluded that most(86.11%) of the foramina present in the zone II followed by zone I (8.33%) then by zone III (5.56%). All foraminawere directed toward the lower end of humerus.Conclusion: By knowing the number and location of the nutrient foramina in humerus would be useful in preventingintra-operative injury of nutrient artery during orthopedic, plastic and reconstructive surgery and will also berelevant in medico legal practice.

ABSTRACT

Introduction: Knowledge of position of nutrient foramina of long bones can be useful in certain surgical procedures. Bone ossification, growth and healing depend on its vascularity. Nutrient artery is the main source of blood supply of bone along with periosteal arteries. The topographical knowledge of these foramina is useful in certain operative procedures, in orthopedics as well as in plastic and reconstructive surgeries.AIM: The present study aims to determine the number and position of nutrient foramen of tibia and fibula and to observe direction and obliquity of nutrient foramina. Subjects and Methods: 100 adult dry bones including 50 tibia and 50 fibula were studied. Nutrient foramina were identified with naked eyes. The obliquity was determined with hypodermic needle. The nutrient foramina location was determined by dividing total bone into segments, the locations were validated by calculating foraminal index. Results: It has been observed that 98% (49) tibia has single nutrient foramina, double nutrient foramiana present in 2%of tibia. Most of the nutrient foramina in tibia are present in upper third i.e 65%(33).Foramina index of tibia is 45.05 with standard deviation of 8.29.In fibula single foramen was observed in 46(92%) and double foramina 2(4) and there is no nutrient foramen in 2(4). In 2 fibulae having double nutrient foramen, proximal foramen was directed downward and distal foramen was directed upwards. In 50%(25) nutrient foramina is present in posterior surface,most of nutrient are in middle third 48(96%).mean foraminal index of fibula is 45.05 with standard deviation of 8.29. Conclusion: Our study has attempted to put together findings from different studies regarding the number and position and obliquity of nutrient foramina of leg bones .The present study will be useful for orthopedic surgeons during procedures like bone grafting and more recently microsurgical vascularised bone transplantation and new graduates to understand the importance of nutrient foramina of long bones.

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

Background: The external opening of the nutrient canal, usually referred to as the nutrient foramen has a particular position in each bone. An understanding of the position and number of the nutrient foramina in fibula is important, as this is one of the most common bones used in bone grafts, vascularized bone microsurgery and mandibular reconstruction. Nowadays fibula flap is the most accepted flaps used in the mandibular reconstruction especially in the malignancy of oral and oropharyngeal regions. Materials and Methods: The present study was conducted in 160 dry human fibula obtained from department of Anatomy, N.S.C.B. Medical college Jabalpur {M.P.}. We have measured the different parameters in each bone according to standard method. Result: In our study we found that 95% bones possess single dominant nutrient foramina. According to Foraminal Index (FI), the position of most of foramina [97%] was fall in Type 2 (middle third of the fibula). The mean foraminal index (FI) was 39.66±5.29. The average total length (TL) of fibula was 35.80±2.53. Conclusion: To conclude that our study provides detailed data about the position and number of nutrient foramina of fibula that is considered as a determining factor for the success of new techniques for bone transplant and resection in orthopaedics.
