NORMAL SCAPULA VARIANT: CLASP LIKE SUPERIOR MARGIN

FINDINGS

Well corticated bridge of bone (Pink arrows) that lies on the superior margin of the scapula with a bone defect inferior to it.

DISCUSSION

• This is a normal variant. Its described in Keats as a Clasp Like scapular margin that’s a result of bone being developmentally absent below it.

 

• This results in a pseudoforamen at the superior scapular margin.
