Supraclavicular foramen

Last revised by David Luong on 17 Jun 2021

The supraclavicular foramen is a normal variant and typically found as an incidental finding on radiographs. It occurs in ~4% (range 2-6%) of the population. 

Supraclavicular foramen appear as an osseous tunnel or tunnels, with the most typical position at the superior aspect of the junction of middle and distal thirds of the clavicle

It transmits the supraclavicular nerve and is most often asymptomatic but it has been reported in the literature as a cause of supraclavicular nerve entrapment syndrome
