Abstract
Introduction The lower end of the humerus has two large fossae, the olecrenon fossa and the coronoid fossa, sepa rated by a thin bony plate that rarely bears an opening known as supratrochlear foramen. Supra trochlear fracture of humerus is very common in the paediatric age group, and it can alter the line of fracture as well as management. Due to its clinical relevance, its presence cannot be ignored. This report discusses a case of a supra trochlear foramen. Case report During routine osteology demonstra tion, we encountered the humerus with supratrochlear foramen. Morpho metric analysis was done and compared with the previous litera tures.
Highlights
The lower end of the humerus has two large fossae, the olecrenon fossa and the coronoid fossa, separated by a thin bony plate that rarely bears an opening known as supratrochlear foramen
A thin plate of bone usually separates olecranon fossa and coronoid fossa of the humerus. This bony plate remains perforated known as supratrochlear foramen (STF), septal aperture or intercondylar foramen of the humerus
Intramedullary nailing of the humerus is sometimes required in the treatment of supracondylar fracture, and it is relatively more difficult in the presence of STF2
Summary
This foramen can alter the radiological findings during examination and may get misdiagnosed as osteolytic lesion or cystic lesion.
