Brief Summary

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.

Eligibility Criteria

Inclusion Criteria: 1. Subjects must be at least 13 years of age. 2. Subjects must have the ability to provide written informed consent. 3. Subjects must have tumor(s) invading bone and requiring surgical excision including but not limited to craniomaxillofacial, spine, long bone, and pelvis. 4. Subjects must be willing to have quality cross-sectional imaging that will allow for use to develop a 3D printed model. Exclusion Criteria: 1. Pregnant or nursing women. 2. Subjects that have a serious systemic pathology. 3. Subjects that have clotting disorders. 4. Subjects that have uncontrolled hypertension. 5. Subjects that are HIV-positive. 6. Subjects that are unable to be randomized; i.e surgical team prefers to use either 3D model or standard cross-sectional imaging for surgical pre-planning. 7. Subject anatomy has changed substantially since the date medical imaging from which the model is derived was obtained (as applicable). 8. Subject is a poor surgical or poor study candidate which
