Three-dimensional virtual reality-assisted surgical planning for neuronavigated sacrectomy of a chordoma: a technical note.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeSacral chordomas are slow growing but locally aggressive tumours with a high rate of local recurrence if not completely removed. Surgical resection with negative margins represents the most important survival predictor but it can be challenging to accomplish. Thanks to improvements in intraoperative imaging and surgical techniques, en bloc resection through a partial sacral resection with wide surgical margins has become feasible but it comes with a significant morbidity rate. In this technical note we detail the virtual reality-assisted surgical planning used during resection.
methodsA 70-year-old patient underwent en bloc resection of the tumor by an antero-posterior two-stage surgery approach. Pre-operatively, based on MR- and CT-imaging, virtual objects were designed, representing the tumour, the surrounding bone and the neurovascular structures. This 3D-model was used to plan the well delimited partial sacral resection and the posterior surgical approach. Intraoperatively the instruments were registered, allowing for a real-time visualization of the tumor, of the neurovascular structures, and for an optimal margin control resection.
resultsPostoperatively the patient was intact in the lower extremities, without any deficit up to S1 roots. An intentional middle-low sacral amputation of S2-S5 roots was necessary to have a wide resection with free margins. At follow-up, the patient did not present any lower extremities motor deficit with an improvement of sensory function on S1 dermatome.
conclusionThree-dimensional virtual reality-assisted surgical planning for neuronavigated sacrectomy in chordoma is useful, feasible and safe. This technology can increase surgeon's chances to perform a larger margin-free resection decreasing the risk of neurovascular damage.
