Incidence of supratrochlear foramen of humerus

Abstract

Introduction: The supratrochlear foramen of humerus is a small hole located above the trochlea of humerus. The supratrochlear foramen was first described by Meckel in 1825. The knowledge of the presence of supratrochlear foramen in the humerus is important for preoperative planning and management of supracondylar fractures and the interpretation of the abnormalities in the radiographs. Materials and Methods: The study was conducted in Jawaharlal Nehru Institute of Medical Sciences, Imphal. 60 dry humerus were studied. The parameters of the humerus. Supratrochlear foramen were measured with digital vernier caliper The supratrochlear foramen observed were photographed. Result and conclusion: The supratrochlear foramen was observed in 5 humerus. The supratrochlear foramen so observed were all on the left side. The incidence of supratrochlear foramen according to our present study is 8.33%. Two of the supratrochlear foramen observed were circular in shape . Another two were oval in shape .The fifth one was a slit. The present study may help the researchers in comparing the incidences of supratrochlear foramen of humerus. KEY WORDS: Humerus, Supratrochlear foramen of humerus.
