Intraoperative 3D scans are a reliable method of determining the position of trocars in vertebral bodies and can lead to a reduction in the morbidity rates associated with puncture errors during kyphoplasty and vertebroplasty, according to a study published in the Journal of Spinal Disorders & Techniques.
Researchers examined the positions of 84 trocars in 42 fractured vertebrae between T11 and L5, which were measured by intraoperative 3D imaging before injecting cement. The intraoperative evaluation of the 3D scans showed 78 correct needle positions, two trocars in an acceptable lateral malposition and four medial malpositions that required revision.
The position of 34 needles determined by computed tomography conformed 100 percent to the results of the 3D scan. Researchers determined that the amount of time it takes to perform intraoperative 3D scans was small and the increased radiation exposure was acceptable.
