MORPHOMETRIC STUDY OF SUPRATROCHLEAR FORAMEN OF HUMERUS

The supratrochlear foramen (STF) is an important variation in the lower end of humerus. The knowledge of the presence of STF in a humerus may be important for preoperative planning for treatment of supracondylar fractures. This study aimed to find out the presence of supratrochlear foramen in lower end of humerus and to measure the dimension of it. The present study was done in 565 dry humeri of unknown sex and age, obtained from B. J. Medical College, Ahmedabad. The STF was measured using digital vernier caliper. In the present study the STF was seen in 133 cases (23.5%) of total humeri, oval shape being more common and present more frequently on left side (28%) compared to right side (19%). Most of the humeri that had no STF showed a translucency of septum, in 52.5% of the humeri. The anatomical knowledge of STF is beneficial for anthropologists, orthopaedic surgeons and radiologists in day to day clinical practice.
