Anatomical evidence for a uniquely positioned suprascapular foramen
Abstract
The suprascapular foramen is a rare but not exceptional variation of the suprascapular notch. The suprascapular notch and suprascapular foramen could lead to pain and muscles atrophy because of nerve compression. In this study, we present a suprascapular foramen which does not correspond to a nerve's trajectory but rather corresponds to a specific bone formation that increases the surface area for muscle attachment. As a consequence, its presence cannot be taken as an indication for neurolysis, contrary to ossification of the foramen in its normal anatomical position. Moreover, this unique foramen is distinguishable from a classical suprascapular foramen on radiographs and, especially, on CT scan images.
