MORPHOLOGIC STUDY OF NUTRIENT FORAMINA IN DRIED FEMURS
Journal Title: Journal of Evolution of Medical and Dental Sciences - Year 2018, Vol 7, Issue 35
Abstract
BACKGROUND Diaphyseal fractures of femur are common cases in Orthopaedics and Traumatology Department. Vascularised bone graft is the preferred method used in bone reconstruction, as it ensures the survival of both donor and recipient bones. Position and direction of nutrient foramina in long bones of lower limbs varies from region to region, race and species. MATERIALS AND METHODS The descriptive study comprised of observation of Diaphyseal Nutrient Foramina (DNF) of 50 adult dried femurs. DNF was identified by their elevated margins and by the presence of a distinct groove proximal to them. Foramina equal to or larger than 24 hypodermic needle size were included. Foramen Index (FI) was calculated using Hughes formula. RESULTS 28 (56%) bones showed single nutrient foramen, 21 (42%) bones showed double nutrient foramina. Nutrient foramen was absent in one bone. Majority of nutrient foramina were found on the linea aspera and posterior medial surface and least on the lateral surface, whereas none were found on the anterior surface. The mean foramen index was 44.07. CONCLUSION The anterior and lateral surfaces of femur are safe for orthopaedic manipulations due to scarcity of nutrient foramina on these surfaces.
