| Abstract: |
| Purpose: To investigate the usefulness of three-dimensional (3D) printing in complex spinal surgery.
Methods: The study was conducted from October 2014 to March 2015 in Shenzhen Second Peoples'
Hospital and 4 cases of complex severe spinal disorders were selected from our department. Among
them one patient combined with congenital scoliosis, one with atlas neoplasm, one with atlantoaxial
dislocation, and the rest one with atlantoaxial fracture-dislocation. The data of the diseased region was collected from computerized tomography scans for 3D digital reconstruction and rapid prototyping to prepare photosensitive resin models, which were applied in the treatment of these cases.
Results: The use of 3D models reduced operating time and intraoperative blood loss as well as the risk of postoperative complications. Furthermore, no pedicle penetrations or screw misplacement occurred according to the postoperative planar radiographic images.
Conclusion: The tactile models from 3D printing allow direct observation and measurement, helping the
orthopedists to have accurate morphometric information to provide personalized surgical planning and
better communication with the patient and coworkers. Moreover, the photosensitive resin models can
also guide the actual surgery with the drilling of pedicle screws and safe resection of tumor. |
