3D Virtual Surgical Planning and Patient-Specific Instrumentation in Spine Surgery
The human spine is a complex anatomical structure that can be considered as the scaffold of the entire body. The spine provides flexibility and stability and protects the spinal cord and crucial neurovascular structures. Surgical intervention in this complex anatomy requires detailed preoperative planning. 3D technology is a relatively new method for preoperative planning, and has proven to increase the predictability, accuracy and speed of many surgical procedures. The aim of this thesis was to develop, implement and validate 3D technology for spine surgery. The first part of the thesis focused on new 3D techniques for planning and placement of spinal screws. 3D-printed drill guides were developed in a cadaveric study and resulted in a submillimeter accuracy. In a subsequent clinical series, 76 screw trajectories were analyzed and found to be positioned safe and accurate. A study that explores the use of screw guidance in addition to 3D-printed drill guides concluded that there was no overall beneficial effect. The part concludes with a randomized trial showing that 3D technology provides a non-inferior alternative to surgical computer navigation in terms of screw insertion accuracy, and therefore has a considerable potential as a navigational technique in spinal fixation. In the following parts 3D technology was developed and validated for spinal deformity surgery and surgery at the craniocervical junction. The thesis concludes with the presentation of a new smart algorithm that ultimately resulted in a significant 3D workflow time reduction, so that in future more patients can benefit from 3D technology.
