Original Research Article Supratrochlear Foramen: An Anatomic and Clinico-Radiological Assessment

Distal end of humerus bears a septum between coronoid and olecranon fossae which is deficient sometimes and forms a foramen called septal aperture or supratrochlear foramen (STF). Our study was conducted on 80 humeri bones (40 right side and 40 left side). The bones were fully ossified and dry. Vernier Calliper was used for taking various measurements. STF was seen in 27.5 % bones. Septum was translucent in 22(55%) humeri on right side and 19(47.5%) on left side (Table 1). Oval and round shapes of STF were observed among which oval shape was found to be maximum (90.9%). The mean transverse diameter was 5.3mm on the right and 6.6mm on the left. The mean vertical diameter was 3.9mm on the right and 4.6mm on the left. The present study can provide more knowledge of STF which may be of great use for orthopaedicians, radiologists and anthropologists
