Figure 4From: Compression and contact area of anterior strut grafts in spinal instrumentation: a biomechanical study Examples of pressure film recordings with block grafts impacted in the anterior intercorporal notch with posterior instrumentation (IF) in (a) an example of A-Type and (b) an example of C-Type group tests. Orientation of the image: left = anterior; right = posterior. Note the absence of contact on the anterior part of the graft due to the lack of tension banding in the C-type injury.Back to article page
