Una delgada lámina ósea entre el olécranon y la fosa coronoides es a veces perforada para formar un agujero denominado foramen supratroclear (STF). Dado que el agujero se encuentra entre el epicóndilo lateral y el medial, también se llama el agujero intercondiloidea. Este agujero fue más frecuente en los huesos prehistóricos. El agujero se ha estudiado en detalle en 214 húmeros secos (131 lado derecho y 83 lado izquierdo) de sexo y edad desconocidos. De 214 huesos, el agujero estaba presente en 67 húmeros (48 lado derecho y 19 lado izquierdo) que muestra una incidencia del 31,3%. El diámetro transversal medio fue de6,5 mma la derecha y5,8 mma la izquierda. El diámetro vertical promedio fue de4,4 mma la derecha y3,9 mmen el lado izquierdo. La distancia media del STF desde la punta del epicóndilo fue de 24,4mm a la derecha y de24,5 mmen el lado izquierdo. Algunos de los huesos mostraron translucidez del tabique óseo (49,3% y 35,9% a la derecha e izquierda, respectivamente). En las radiografías simples, el agujero puede simular una lesión osteolítica. El conocimiento anatómico de STF puede ser beneficioso para los antropólogos, los cirujanos ortopedistas, los radiólogos y en la práctica clínica diaria.
A thin bony plate between the olecranon and coronoid fossa is sometimes perforated to form a foramen named the supratrochlear foramen (STF). Since the foramen lies between the lateral and the medial epicondyle, it is also called the intercondyloid foramen. This foramen was more common in prehistoric bones. The foramen was studied in detail in 214 dried humeri (131 right side and 83 left side) of unknown sex and age. Out of 214 bones the foramen was present in 67 humeri (48 right side and 19 left side) showing the incidence as 31.3%. The mean transverse diameter was 6.5mm on the right and 5.8mm on the left. The mean vertical diameter was 4.4mm on the right and 3.9mm on the left side. The mean distance of the STF from the tip of the medial epicondyle was 24.4mm on the right and 24.5mm on the left side. Some of the bones showed translucency of the bony septum (49.3% and 35.9% on right and left respectively). On plain radiographs, the foramen may mimic as an osteolytic lesion. The anatomical knowledge of STF may be beneficial for anthropologists, orthopedic surgeons and radiologists in day-to-day clinical practice.
