These AVMs can result in bleeding, heart failure and neurologic deficits.

First described by the orthopedist John R Cobb, the Cobb angle is the angle between a line drawn parallel to the end plate of the rostral most vertebral body in spinal curve and a line drawn parallel to the end plate of the caudal most vertebral body of a spinal curve. It was originally used to describe a curve seen on a coronal view of the spine on X-ray. More recently it has also been used to describe sagittal spinal curvature, especially those seen after trauma.
