ABSTRACT
Background: Major part of a long bone derives nutrition from nutrient arteries, which pass through nutrient foramina seen on shaft of a long bone. Therefore, data regarding distribution of nutrient foramina is crucial to obtain a vascularized bone graft and to avoid damaging blood supply of a bone. Present study focuses on morphological details of nutrient foramina of ulna in South Indian population.
Material and Methods: Present study was conducted on 200 dry, adult ulnae bones, irrespective of age and sex. Bones were obtained from department of Anatomy, Apollo Institute of Medical Sciences and Research, Hyderabad. Laterality of bones was determined. Location and number of nutrient foramina on diaphysis was noted. Total length of the bone and distance of nutrient foramina from proximal end of bone were recorded. Foraminal index of all bones was calculated using Hughes formula. Statistical analysis of data was done applying descriptive statistics.
Results: All bones had at least one nutrient foramen, directed to the proximal end of bone. Double nutrient foramina were observed in 6% of bones. No correlation was found between length of bone and duplication of foramina. Majority of nutrient foramina were found on anterior surface of shaft (74.05%) and in middle third of the bone (60%) with foramen index between 33.34% - 66.66%. Mean foramen index was 35.83 ± 6.12.
Conclusion: The study provides population-specific data on topographical details of nutrient foramina of ulnae bones, which can be of use to orthopedic surgeons to safeguard blood supply of ulna and yield better results.
Key words: Nutrient foramina, Ulna, Foraminal index, South Indian population.
