This atlas provides a selection of operations for intra- and extradural pathologies of the spinal cord and its nerve roots. Pathologies involving the spinal cord threaten the patients  mobility, independence or even life. Fortunately, the overwhelming majority are of benign nature, so that surgery plays an important role or even represents their treatment of choice. With modern imaging and microsurgical techniques neurological functions can be maintained or even improved for the majority of patients.<div>The content is presented in a standardized fashion: the preoperative history is followed by preoperative images leading to a preoperative diagnosis and surgical strategy. The intraoperative images intend to illustrate individual surgical steps one after the other to guide the reader through each of these operations. Each case is concluded with postoperative images and information on clinical outcome.
