A Study on Variations of Nutrient Foramen of Humerus and Its Clinical Significance
Journal Title: International Journal of Medical Research Professionals - Year 2018, Vol 4, Issue 5
Abstract
Background: Nutrient foramen is an opening in shaft of humerus which conducts nutrient vessels for medullary cavity. Nutrient artery is the major source of blood supply to long bone. Knowledge of nutrient foramen is important for orthopedic surgeon while doing any procedure on humerus like bone grafting, plating and also plays an important role in fracture healing. Aims and Objectives: To determine the number, direction and location of nutrient foramen of humerus. Methods: The present study was conducted on 62 adult humeri (32 of right side and 30 left side) collected from Department of Anatomy, SGT Medical College, Gurugram, Haryana during the period of 15th June to 31st July 2017. Each humerus was observed for number, direction and location of nutrient foramen in relation with surface, border and zone. Results: In the present study it has been observed that 61% of humeri had a single foramen, 31% double foramen and 8% had triple foramen. Majority of nutrient foramen (54.95 %) present on antero- medial surface, 12.08 % on antero-lateral surface, 12.08 % on posterior surface, 19.78 % on medial border and 1.09 % on lateral border. It was also concluded that most (94.50%) of the foramina present in the zone II followed by zone III (3.30%) then by zone I (2.19%). Conclusion: Knowledge of number and location of the nutrient foramina in humerus will be helpful in preventing intra-operative injury of nutrient artery during orthopedic, plastic and reconstructive surgery and will also be relevant in medico legal practice.
