AIM OF THE STUDY
The aim of the present study is to determine the number, direction of nutrient foramina in human bones of forearm and to determine the most common location of nutrient foramina of bones in the forearm and to calculate the foramen index (FI) of the bones of the forearm.
PLACE OF THE STUDY
This study was done in the Department of Anatomy of Rajiv Gandhi Institute of Medical Sciences[RIMS], Kadapa, Andhra Pradesh.
PERIOD OF STUDY
This study was conducted during the month of September-October 2015 (Two months study).
MATERIALS AND METHODS
One hundred and four unknown dry human forearm bones namely radius and ulna constituted the materials for the present study. These bones were studied [radii 54 (28Lt+26Rt), ulnae 50 (28Lt+22Rt)] from the Dept. of Anatomy of Rajiv Gandhi Institute of Medical Sciences, Kadapa. Andhra Pradesh. Each bone was studied for the presence of nutrient foramina, their number, location and the direction were carefully studied and recorded in various tables.
RESULTS
Twenty eight radii of the left side were studied. A single nutrient foramen was present in 27 bones, double nutrient foramina seen in only one bone (Specimen No. 20), (Figure No. 1). Nutrient foramina were present on the anterior surface in 26 bones (Figure No. 2), and in two bones they were seen on the interosseous border (Specimen Nos. 6 and 14), (Figure No. 3). Twenty six radii of the right side were studied. A single nutrient foramen was present in twenty five bones, double NF seen in one bone. (Specimen No. 10). Nutrient foramen was present on the anterior surface in twenty three bones and in two bones, they were present on the interosseous border (Specimen Nos. 14 and 19) and in one bone on the posterior surface (Specimen No. 15), (Figure No. 4). The mean length of radius on left side was 23.6 cm; mean distance of NF from proximal end of bone was 7.8 cm. (Figure Nos. 8 and 9). The mean length of radius on right side was 24.6 cm; mean distance of nutrient foramen from proximal end of bone was 8.2 cm.
Among 28 ulnae studied on the left side, single NF was present in all 28 bones. NF was present on the anterior surface in 26 bones, (Figure No. 5), on the interosseous border in one bone (Specimen No. 15), (Figure No. 6) and on the anterior border in one bone (Specimen No. 27), (Figure No. 7). Among 22 ulnae studied on the right side, single NF was present in all 22 bones. NF was present on the anterior surface in 21 bones, on the interosseous border in 1 bone (Specimen No. 19).
CONCLUSION
This study on nutrient foramen has profound clinical surgical importance, hence studied and reported.
