Introduction: Nutrient foramen is an opening into the bone shaft, which gives passage to the blood vessels of the medullary cavity of a bone. The major blood supply to the bone is through nutrient arteries, which enter through nutrient foramina. The supply is essential during the growing period and early phases of ossification.

Aim and objectives: Study of relative relationship between the length of bone and distance of nutrient foramen from either ends is useful in calculating the length of a bone from a given fragment, which is important in medico–legal and anthropological work. In free vascular bone grafting, the nutrient blood supply is extremely important and must be preserved to promote fracture repair, a good blood supply being necessary for osteoblast and osteocyte cell survival, as well as facilitating graft healing in the recipient.

Material and methods: Present study was conducted in the department of Anatomy Government Medical College, Jammu. 100 dry adult human radii were selected for the study.

Results: In the present study, out of total radii 52 radii were of right side and 48 were of left side. Out of 52 right side radii, 49 radii had a single nutrient foramen and 3 radii showed absence of any nutrient foramen. Out of 48 left side radii, 46 radii had single nutrient foramen and no nutrient foramen was seen on 2 radii of left side.
