Abnormal healing of fractures has been divided into three groups: delayed healing, reactive and non-reactive pseudoarthrosis. There are many transitions between these. Routine radiography can only classify these after their morphological appearance. Angiography is able to provide information regarding the vitality of major and minor fragments according to the type of para- and interfragment vascularisation; in some cases there may also be some neovascularity. The potential for union depends directly on the vascularisation of the surrounding muscles, of the subcutaneous tissues and of the skin. Vascular changes result in the formation of an autonomous circulation, independent dynamically of the vessels in the extremity and which can guarantee an increased saturation during healing by new bone formation. Angiography can provide an estimate of the likelihood of union and thereby provide a prognosis; it can also help to predict the fate of autotransplants and the strength of surgically reconstructed bone, since inadequate circulation may result in devitalisation of fragments.
延迟愈合、反应性和非反应性假关节。这些情况之间存在许多过渡状态。常规放射成像只能在骨折出现形态学表现后对其进行分类。血管造影能够根据骨折块周围和骨折块间血管化的类型提供有关主要和次要骨折块活力的信息；在某些情况下，可能还会有一些新生血管形成。骨折愈合的可能性直接取决于周围肌肉、皮下组织和皮肤的血管化情况。血管变化会导致自主循环的形成，该循环动态独立于肢体中的血管，并且能够在新骨形成的愈合过程中保证更高的血氧饱和度。血管造影可以评估骨折愈合的可能性，从而提供预后情况；它还可以帮助预测自体移植的结果以及手术重建骨的强度，因为血液循环不足可能导致骨折块失活。
