Clinical trials

This prospective, multi-center, randomized controlled study aims to assess the efficacy of utilizing 3D printed models in preoperative planning for the excision of tumors involving bony structures within the body. The study is expected to last approximately 12 months and involve up to 150 subjects across up to 5 sites. Subjects will be randomized in a 1:1 ratio into either the experimental arm, utilizing 3D printed models and imaging, or the active comparator arm, using only imaging. Primary endpoint: Operative time of surgical procedure. Secondary endpoints: Reduction of blood loss, proportion of postoperative adverse events, and negative tumor margins. Exploratory endpoints: Surgical planning ease, changes in surgical plan, and surgeon satisfaction.
