A Study of Diaphyseal Nutrient Foramina in Human Tibia

Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 17, Issue 2

Abstract

The nutrient artery is the major source of blood supply to the long bones. It enters through a nutrient foramen which runs obliquely and usually directed away from the growing end. The nutrient artery of tibia is the largest nutrient artery of the body. The knowledge of presence, number, location and direction of nutrient foramina has clinical significance in orthopaedic procedures. Materials and methods: The present study was conducted on 100 dry adult tibia bones (49 Right, 51 Left) of unknown sex and origin from the Department of Anatomy, Regional Institute of Medical Sciences, Imphal, Manipur. The lengths of tibia were measured using an osteometric board. For the purpose of study, the tibia was divided into three equal segments. The presence, number, location and direction of nutrient foramen were noted. Results: The nutrient foramen was located in upper third of tibia in 67.2%, in middle third in 32.7% of tibia and no nutrient foramina were found in lower third. Out of 100 bones, 91% of tibia has single foramina, 8% has double nutrient foramina and 1% has triple foramina. Most of the nutrient foramina were located on the posterior surface (96.3%) compared to medial and anterior surfaces. Out of 110 nutrient foramina, 3 were seen directing towards proximal end i,e. towards the growing end. Conclusion: The study will provide the essential data for nutrient foramen which will be helpful in surgical orthopaedic procedures.
