INDEXING OF THE NUTRIENT FORAMINA OF FOREARM BONES

Rupinder Singh, Mannat Rangi, Dr. Arun Sharma

Abstract :

INTRODUCTION- Nutrient foramina (NF) are the cavities present on the diaphysis of long bones that conduct the nutrient arteries and peripheral nerves of the bones. The detailed knowledge of position and number of NF is very important during bone transplants and resection. They also provide baseline data to calculate the length of the bones from the given fragments. OBJECTIVES: To determine the foraminal index of the nutrient foramen in radius and ulna. METHODS: 50 radii and 50 ulnae were taken. In all the bones nutrient foramina were identified. The total length and distance of the foramen from the proximal end of the bones were measured by using the digital vernier caliper. Mean foraminal index was calculated for both radius and ulna. (Foramen index= distance of the foramen from the proximal end/bone length). Also, the number and the distribution of the foramina concerning specific regions/surfaces of the diaphysis were identified. RESULTS: All the bones had nutrient foramen directed towards the elbow. The mean foraminal index was found to be different for the different surfaces in radius and ulna respectively. Nutrient foramen was double in 4%radii and 4% ulnae both. Also, majority of the bones had a nutrient foramen on their anterior surface. CONCLUSION: The foraminal index of radius and ulna can be useful in certain surgical procedures to preserve the circulation. Also, the accurate anatomical description of these foramina would be useful in microvascular bone transfer in the forearm.
