摘要：Background and aims: The recent developments in the field of bone grafting surgeries make it imperative for asurgeon to understand precisely the topography of the nutrient foramina to ensure procedural success withoutvascular compromise.Materials and Methods: The study involved 205 bones, which included 70 humerus, 71 radii and 64 ulnae. Theposition and number of the primary diaphyseal nutrient foramina in each of the bones was studied.Results: It was observed that all the bones have a single primary nutrient foramen. The mean foraminal indexwas 55.41 for humerus, 34.84 for radius and 35.86 for ulna. In the humerus, the primary diaphyseal foramen isusually observed in the middle third of the bone and in the radius and ulna it is observed predominantly in thejunction between the upper and middle third. In the humerus the foramen is predominantly seen on the anteromedialsurface (95.71%). In the radius and ulna, the primary diaphyseal foramen was predominantly seen on theanterior surface with a 91.54% incidence in radius and 100% incidence in the ulna.Conclusion: An orthopedic surgeon performing a bone graft or a joint replacement or internal fixation involvingprecise positioning of plate or a vascularized bone microsurgery must be familiar with the precise location ofthe nutrient foramen for preserving the vasculature of bone and ensuring good postoperative prognosis.
