Abstract Background: Humerus is the bone of the arm & the longest bone of the upper limb. The main source of nutrition to long bone during growth & ossification is nutrient artery which passes through the nutrient foramen. The anatomical knowledge of these foramina is useful in certain operative procedures to preserve the circulation.
Methodology: The study was conducted on 100 dry adult human Humerus of both sides of unknown sex, collected from department of Anatomy, Mysore medical college & research institute, Mysuru, Karnataka. Total humerus length along with the location, number, and direction of all the nutrient foramen present were recorded. The bones were photographed & data obtained was tabulated, results noted and the inference was drawn.
Result: The nutrient foramina were observed in all 100 Humerus, single nutrient foramen in 72 (Rt-37 & Lt-35) bones, double nutrient foramen in 24 (Rt-10 & Lt-14) bones, Triple nutrient foramen 01 (Rt) and Absent nutrient foramen – 03 (Rt-02 & Lt-01) The most common location of nutrient foramen was present on anteromedial surface, near its middle.
Conclusion: The anatomical knowledge of nutrient foramen is important for orthopaedic Surgeons during surgical procedures such as fracture repair, bone reduction, external & internal fixation device & bone grafting.
