Abstract Background and Aim Nutrient foramina form important landmarks on human bones as they form portal of entry for nutrient artery. Nutrient artery is an important source of blood supply for a growing bone. Different parameters of nutrient foramina are important in various procedures such as vascularized bone grafting, tumor resections, fracture repair, and other surgical procedures in orthopedics. The objective of the present study was to report the number, position, direction, size, and foraminal index of nutrient foramen in the femur, tibia, and fibula. Materials and Methods The present study analyzed the location, direction, size, and the number of nutrient foramina in the diaphysis of 180 long bones of the lower limbs of adults: 60 femurs, 60 tibiae, and 60 fibulae. Result The location of the nutrient foramina is predominant on the posterior aspect of the lower limb long bones. Single nutrient foramen found in the tibia (100%), femur (48.3%), and fibula (60%) may represent as a single source of blood supply. The majority of the femur (50%) and few fibulae (5%) had a double nutrient foramen. The mean foraminal index for the lower limb bones was 40.5% for the left and 38.2% for the right side of the femur, 31.69% for the left and 32.3% for the right side of the tibia, and 32.7% for the left and 31.7% for the right side of the fibula. Conclusion The present study provides information on the number, size, position, and direction of nutrient foramina of the femur, tibia, and fibula bones.

BACKGROUND Nutrient foramina are seen in the shaft of long bones. They vary in number, size and their position on the surface of bones. It transmits the nutrient artery which is the main source of blood supply to the long bones. We intend to study the location, number, type and direction of primary nutrient foramina (PNF) on the shaft of tibia. METHODS The descriptive study was done using 120 tibiae (right-66, left-54) from Department of Anatomy, Govt. Medical College, Thiruvananthapuram. Length of each bone and distance of the nutrient foramen from the upper end of tibia was measured using osteometric board. The location of the primary nutrient foramina on the surface of tibia, the direction of the nutrient canal and the presence of secondary nutrient foramina were noted. RESULTS Single primary nutrient foramina were located on the posterior surface of 113 tibiae. 4 tibiae showed PNF and secondary nutrient foramina (SNF). No nutrient foramina were observed in 3 tibiae. CONCLUSIONS The precise knowledge and topography of PNF of tibia will help orthopaedic surgeons in minimising damage to vasculature of tibia during various surgical procedures.

 Background: The role of nutrient foramen (NF) in nutrition and growth of the bones is evident from term Nutrient itself. The nutrient foramen is opening of nutrient canal on the surface of shaft of the bone which conducts the nutrient artery and the peripheral nerves to bones. Long bones receive most of the interosseous blood supply (70% to 80%) from the nutrient arteries and remaning (20% to 30%) through the periosteal vessels. Nutrient arteries play an important role in nutrition and growth of the bones particularly during early phases of ossification and growth. The present study is of great importance to orthopedic surgeons in planning repair of fracture, amputation and bone grafting procedures.Aim and objective of study: A study regarding nutrient foramina in femur was not conducted in the past in Nepal. Its importance in orthopedic procedures has inspired us to undertake this study.Materials and methods: This study was conducted on 100 adult dry femur bones (50 right and 50 left). All the important parameters were studied using osteometric board, vernier calipers, and needles of different gauges.Results: Mean distance of nutrient foramen from upper end was 18.09 cms. The most common location of NF was on lateral surface 58.8%. In 71% femur only one NF was seen, while 25% had two NF, 1% femur had three NF and 3% femur had no NFs. In 64.5% femur big size or dominant NFs were seen in present study.Conclusions: The findings of this study on nutrient foramen adds to the information from studies in the past by other authors. The fact that maximum number of the nutrient foramina are present in the middle third of the shaft of the femur is of clinical importance for proper diagnosis, planning of surgery and predict the prognosis. JNGMC,  Vol. 14 No. 2 December 2016, Page: 44-49

Background Free vascularised fibular bone grafting has gained popularity in various Orthopaedic and Oral & maxillofacial reconstructive surgeries. The objective of the present study was to identify the morphology and topography of nutrient foramina of fibula and to determine the foraminal index (FI) of the fibula using a more surgeon friendly bony landmark. Methods The study comprised examination of 100 fibulae specimens. Each bone was divided into 03 parts and topographical analysis was performed on each section. The nutrient foramina were identified macroscopically using size 24-gauge needle. Modified Hughes formula was used to calculate the foraminal index using distance of foramen (DF) from distal end which is easier to palpate in living human beings, total length of fibula (TL); and the formula was DF/TL x100. Results With respect to fibulae, 98% had single foramen and foramen was absent in 2%. The mean foraminal index (FI) was 56% for fibulae using modified Hughes’ formula. The majority of the fibulae showed nutrient foramen in the middle 3rd in relation to distal end of fibula. Conclusion The study provides information on the morphology of nutrient foramina in relation to easily palpable landmark on living human beings, which can provide guidance to surgeon while performing microvascular bone transfer procedures.
