[Conservative operative procedure in surgery of the spine]

An operative treatment within the spine due to the traumatic, neoplastic, vascular or other indications frequently result in complications as disturbance of the shape, flexibility, strength, mobility of the spine and injury of neural structures of a various degree. These complications may be prevented by minimizing surgical injury to the bone, ligaments, nerves and vessels and by adequate intra- and postoperative stabilization of the spine. The management will be effective only if the level, range and type of injury as well as spine tolerance against mechanical loads is diagnosed accurately. The authors included case reports.
