Introduction: The Clavicle is a modified long bone and only long bone which is placed horizontally and subcutaneously at the root of neck. It transmits the weight from upper limb to the axial skeleton. Nutrient foramen is the largest foramen on the long bones through which nutrient artery for the bones passes. The nutrient artery is the principal source of blood supply to a long bone, particularly important during its active growth period in the embryo and foetus, as well as during the early phase of ossification. The bone has a cylindrical part called the shaft and two ends, lateral and medial. The shaft is divisible into the lateral one-third and the medial two-thirds. The inferior surface of shaft of clavicle presents a subclavian groove. A Nutrient foramen lies at the lateral end of the groove running in a lateral direction. Aims & objectives: To note the position, number and direction of nutrient foramen Materials and Methods: The present study was performed on 100 adult human clavicles of unknown sex and age collected from the department of anatomy, Mysore medical college and research institute, Mysore. Clavicles were examined by direct observation to note the position, number and direction of nutrient foramen. A magnifying lens was used to observe the foramina. Results: The study was conducted on 100 adult human clavicles (50 right and 50 left), and we observed the following results: Nutrient foramina were present in 97 clavicles - 49 clavicles (right) and 48 clavicles (left). Single foramina was present in 80 clavicles, 41 clavicles (right) and 39 clavicles (left) Double foramina were present in 17 clavicles, 8 clavicles (right) and 9 clavicles (left). Absence of nutrient foramina were found in 3 clavicles, 1 clavicle (right) and 2 clavicles (left). All foramina were directed towards the acromial end of the clavicle. Conclusion: The knowledge of anatomical variations of nutrient foramina in clavicles are important for surgeons for performing surgical procedures like bone grafting and microsurgical vascularised bone transplantation. KEY WORDS: Clavicle, Nutrient Foramen, Bone Graft.

BACKGROUND The clavicle or collar bone is a modified long bone. It is the first bone to ossify in the membrane. The inferior surface of shaft of clavicle presents a subclavian groove. A nutrient foramen lies at the lateral end of the groove. The nutrient artery is derived from the supraclavicular or clavicular branch of thoracoacromial artery. A bone is supplied by a nutrient artery which passes through the small tunnel called as nutrient foramina. In orthopaedic procedures to preserve the circulation, the topographical knowledge of the nutrient foramen is important. The study was undertaken to analyse nutrient foramina in adult human clavicles in relation to their number, position, direction, and distribution over bone length. METHODS Our study consisted of 67 adult dry human clavicles (31 right sides and 36 left sides). The number, topography and direction of the foramina were studied. The distance of foramina from the sternal end & total length of the clavicles were measured in millimetres by using digital Vernier calipers. The foramen index was calculated by applying the Hughes formula: FI = (DNF TL) x 100. RESULTS Nutrient foramina were present in all the clavicles. Most of the clavicles have single nutrient foramen. We observed 62 (68.13 %) foramina on the posterior surface mostly in the middle 1 / 3rd region. All the nutrient foramina were directed towards acromial end and the foramina index (FI) was 50.2. CONCLUSIONS The topographical knowledge of the nutrient foramen is important in orthopaedic procedures like nail plating, K wire fixation, reduction, internal fixation devices for the treatment of fracture, coracoclavicular ligament repair and in free vascularized bone graft to preserve the circulation.

BACKGROUND Tibia is the weight bearing bone of the leg. Usually it has a single nutrient foramen located posteriorly near the soleal line and transmits a branch of posterior tibial artery. The nutrient artery is the principal source of supply to a long bone. We carried out this study to find out the number, size, location, position and direction of the diaphyseal nutrient foramen in dried human tibia in Goan population. METHODS The study was carried out on 66 unpaired dry human tibiae of unknown age, gender and without deformity in the Department of Anatomy, Goa Medical College, using sliding and digital Vernier callipers, 20- and 24-gauge needles. Hughes formula was used to compute foraminal index. The data was statistically analysed with SPSS software version 23. RESULTS Most of the tibia in our study had a single nutrient foramen. Majority of the nutrient foramina were medium sized and directed downwards in our study. In 81.42 % tibiae, the nutrient foramina were present in the upper 1 / 3 rd of the shaft and in 18.57 % in the middle 1 / 3 rd of the shaft of the bone. Almost all nutrient foramina in the upper 1 / 3 rd of posterior surface were situated lateral to the soleal line. We computed the mean foraminal index as 30.25 % with standard deviation of 6.14. CONCLUSIONS A proper knowledge of morphometry and topography of the nutrient foramen is of utmost importance to orthopaedic surgeons as the nutrient artery may get damaged if fracture line passes through the nutrient canal. Also, it will help the surgeon to conserve vascular supply while performing bone grafting and fracture reduction. KEYWORDS Nutrient Foramen, Morphometry, Foraminal Index, Soleal Line

BACKGROUND Nutrient foramen of humerus is an opening in the shaft of humerus which conducts nutrient vessels for medullary cavity. Major source of blood supply to long bone is the nutrient artery. Knowledge regarding nutrient foramen is important for orthopaedic surgeons while doing any procedure on humerus like bone grafting, plating and also plays an important role in fracture healing. We wanted to determine the location, number, and direction of nutrient foramen of humerus. METHODS The observational study was conducted on 72 adult humeri (36 of right side and 36 of left side) collected from Department of Anatomy, Kurnool Medical College, Kurnool, Andhra Pradesh from 15th September to 31st October 2020. Each humerus was observed for location, number, and direction of nutrient foramen in relation with surface, border andzone. RESULTS In the present study it has been observed that 61 % of humeri had a single foramen, 31 % had two foramina and 8 % had 3 foramina. Majority of nutrient foramina (54.95 %) were present on antero-medial surface, 12.08 % on anterolateral surface, 12.08 % on posterior surface, 19.78 % on medial border, and 1.09 % on lateral border. It was also concluded that most (94.50 %) of the foramina were present in the zone II followed by zone III (3.30 %) then by zone I (2.19 %). CONCLUSIONS Knowledge of number and location of the nutrient foramina in humerus will be helpful in preventing intra-operative injury of nutrient artery during orthopaedic, plastic and reconstructive surgery; and will also be relevant in medico legal practice.

 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

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 femur is the typical long bone of lower limb which extends from the pelvis to the knee. It forms the skeleton of the thigh, bears body weight, supports movement of legs; provide attachment to muscles, form blood cells and acts as a store house for calcium and phosphate. The nutrient foramina are cavities that conduct the nutrient arteries and the peripheral nerves. The majority blood supply for femur originates from the nutrient arteries, mainly during the growing period and during the early phase of ossification. In bone grafts the nutrient blood supply is crucial and it should be preserved in order to promote the fracture healing. Objective: The anatomy of nutrient foramen of femur is very essential for orthopedic & vascular surgeons as well as to radiologists for planning of treatment. Materials and method: This cross sectional study was carried out in the department of Anatomy, Sir Salimullah Medical College, Dhaka, Bangladesh from July 2011 to June 2012. The study comprised 199 fully ossified left sided dry femur of both sex (n=89 male, n=110 female). Sampling technique was purposive. Morphometric and topographic study was carried out on all samples by direct physical and photographic methods. Results: The most common position of nutrient foramen on the shaft of femur was found on the middle 1/5th in both male and female femur (50.78% in male and 56.86% in female respectively). Conclusion: The anatomical knowledge about this study might be useful in certain surgical procedures as well as micro vascular bone transfer to preserve the circulation.DOI: http://dx.doi.org/10.3329/dmcj.v1i1.14970 Delta Med Col J.
