ABSTRACT
Introduction: The diaphysial blood supply to the long bones mostly depends on the nutrient artery. Multiple foramina in bones suggest that one of them would be the main foramen and others are the accessory foramina. The growth and repair of a long bone is dependent on its blood supply through nutrient artery. So any fracture passing through the foraminal area is likely to heal poorly. During any surgical procedure in this area, if the nutrient artery is damaged it will lead to a poor outcome.Keeping this fact in view this comprehensive study on morphometry of nutrient foramina of upper limb long bones was undertaken.
Materials and Methods: A total number of 270 upper limb long bones (100 humerii, 90 radii and 80 ulnae) were studied to find out the number, direction and location of nutrient foramina in each bone. The total length of each bone and the distance of the nutrient foramen from its proximal end were measured to calculate the foraminal index using Hughes formula. The antero posterior and transverse diameters of the bones at the level of nutrient foramen were measured to assess the correlation between number of nutrient foramina and size of bone.
Results: Multiple nutrient foramina were observed in 36% of humerus, 22.5% of ulnae and 3.3 % of radii. Nutrient foramina were mostly located in middle third of the bones (96.5% in humerus, 87% in ulna and 60% in radius). The commonest position of nutrient foramina was either medial border or anteromedial surface in humerus. In the radius and ulna they were situated mostly on the anterior surface. All foramina were found to be directed towards the lower end.
CONCLUSION: This study will provide important morphological and topographical information about nutrient foramina for orthopaedics procedures in the upper limb.
KEY WORDS: Nutrient Foramen, Humerus, Radius, Ulna, Foraminal Index.
