Study of Nutrient Foramina in the Long Bones of Human Upper Limb in Ajmer, Rajasthan
Journal Title: International Journal of Medical Research Professionals - Year 2018, Vol 4, Issue 2
Abstract
Introduction: The nutrient foramina are cavities that conduct the nutrient arteries and the peripheral nerves. The major blood supply for long bones originate from the nutrient arteries, mainly during the growing period and during the early phases of ossification. Materials and Methods: The material of the present study consisted of 105 adult human cleaned and dried bones of the upper limb. They were divided into three groups, 35 bones of each, for determination of the number, position, size, direction and obliquity of the nutrient foramina in the human upper limb long bones. They were obtained from the osteology collection held in the Department of Anatomy, Jawahar Lal Nehru Medical College, Ajmer, Rajasthan. Only well-defined foramina on the diaphysis were accepted. Foramina at the ends of the bone were ignored. Results: The majority of nutrient foramina in all bones studied were single in number and were secondary in size. Most of the nutrient foramina were concentrated in the middle third and were mostly located on the anterior surface of the shaft of bones. Most of the long bones follow the dictum “Towards the elbow I go, away from the knee I flee” and the direction of nutrient foramen is opposite to growing end i.e. away from the elbow. Conclusion: The study confirmed previous reports regarding the number and position of the nutrient foramina in the long bones of the limbs. Exact position and distribution of the nutrient foramina in bone diaphysis is important to avoid damage to the nutrient vessels during surgical procedures.
