Omovertebral bone
The omovertebral bone (os omovertebrale) is present in ~35% (range 19-47%) of cases of Sprengel deformity.
Gross anatomy
It runs from the superomedial border of the scapula to the spinous processes, transverse processes or laminae of C4 to C7 1,2. Occasionally it can be bilateral 2. The connection from the scapula to the vertebrae may be fibrous or osseous.
