Are the biomechanical characteristics of cranial sutures altered by spring cranioplasty forces?
Cranial suture compliance is modified in the presence of continuous spring cranioplasty forces. Thickening of the coronal sutures, which have been expanded in a shear-like manner, increases their three-dimensional surface area and may contribute to the relative lack of relapse observed after early spring removal.
Paired studies that used intravascular ultrasound showed that early endothelial dysfunction predicts the development of allograft arteriosclerosis during the initial year posttransplant. This early pathophysiological feature is likely an important marker that could be useful in therapeutic trials.
