Morphological Variations of Nutrient Foramina in Lower Limb Long


Background: The nutrient arteries, which enter through the nutrient foramen, provide the majority of blood supply to the long bones. A nutrient foramen is a hole in the bone shaft that allows blood vessels in the medullary cavity of the bone to pass through. The nutrition foramen of all bones is directed away from the growing end and has a specific position for each bone. The goal of this study was to look at the topographic architecture and morphology of the nutrition foramina in adult human lower limb long bones. Materials and Methods: A total of 150 lower limb long bones, 50 femora, 50 tibiae, and 50 fibulae, were used in the study. The bones were taken from the Punjab Institute of Medical Sciences’ department of anatomy in Jalandhar. The number and position of nutrient foramen in distinct lower limb long bones were observed to vary. Double and triple foramina were found in the femur. Nutrient foramen were not found in the femur or fibula. Conclusion: Knowing the topography of these foramina is useful in avoiding injury to the nutrition vessels during specific surgical procedures in orthopaedics, as well as in plastic and reconstructive surgery.
