Abstract: Comprehensive information about the blood supply of long bones is one of the vital factors for success of new techniques in bone transplant and resection in orthopaedics. During transplant techniques, the variant of distribution of nutrient foramina guides the operating surgeons to place the graft without injuring the nutrient arteries. The topography of nutrient foramina may contrast in its growing and non-growing end, specific understanding of this becomes essential in certain surgical procedures to conserve the circulation. Hence present study was planned to generate the data on nutrient foramen in tibia from Bihar region and to compare the findings with the similar studies done in other parts of the world. The present study was planned in the Department of Anatomy, Anugrah Narayan Magadh Medical College, Gaya. The study was performed from the duration of feb 2017 to nov 2017. Total 30 tibia were samples were selected in the present study. The presence of nutrient foramina was confirmed by identifying a well-marked grove which led to the commencement to the foramen. Number, distribution and direction of nutrient foramen in relation to specific surfaces of tibiae were analysed. Only diaphyseal nutrient foramina were observed in all tibiae. Direction of the nutrient foramen was carefully observed by using a magnifying hand lens and then passing a fine needle (25 gauges) through the foramen to confirm its patency and direction. The knowledge of exact location of nutrient foramen of tibia is highly useful for the surgeons who perform fracture repair or are involved in surgical interventions of tibia. So we measured the distance of nutrient foramen from junction of upper & middle 1/3rd of the shaft and the Soleal line.
