Rationale: Three-dimensional (3D) printed templates can be designed to match an individual's anatomy, allowing surgeons to refine preoperative planning. In addition, the use of computer navigation (NAV) is gaining popularity to improve surgical accuracy in the resection of pelvic tumors. However, its use in combination with 3D printing to assist complex pelvic tumor resection has not been reported. Patient concerns: A 36-year-old man presented with left-sided pelvic pain and a fast-growing mass… 
Use of three-dimensional printing and intraoperative navigation in the surgical resection of metastatic acetabular osteosarcoma
A 21-year-old man underwent a joint-preserving posterior acetabular resection of metastatic osteosarcoma using a three-dimensional (3D) printed model and intraoperative navigation, which afforded him palliative benefit, improved quality of life and, conceivably, prolonged survival in the setting of a devastating prognosis.

Recommendations provide guidance for approaches and tools in medical 3D printing, from image acquisition, segmentation of the desired anatomy intended for 3D print, creation of a 3D-printable model, and post-processing of 3D printed anatomic models for patient care.
Comparison between free-hand and O-arm-based navigated posterior lumbar interbody fusion in elderly cohorts with three-level lumbar degenerative disease
The O-arm-based navigation is an efficacious auxiliary technique which could significantly improve the accuracy of pedicle screw insertion, especially in cases of patients with complex anatomic degenerative diseases, without sacrificing the feasibility and reliable outcome of traditional PLIF.

Printed Three-dimensional Anatomic Templates for Virtual Preoperative Planning Before Reconstruction of Old Pelvic Injuries: Initial Results
The 3D printing planning technique for pelvic surgery was successfully integrated into a clinical workflow to improve patient-specific preoperative planning by providing a visual and haptic model of the injury and allowing patient- specific adaptation of each osteosynthesis implant to the virtually reduced pelvis.
Osteoid Osteoma of the Spine: A Novel Technique Using Combined Computer-Assisted and Gamma Probe-Guided High-Speed Intralesional Drill Excision
The combination of both computer-assisted surgery and &ggr; probe-guided high-speed drill excision for osteoids osteoma of the spine helps to localize and excise the nidus of the osteoid osteoma with minimal bone resection of the posterior spinal structures.
Can computer navigation-assisted surgery reduce the risk of an intralesional margin and reduce the rate of local recurrence in patients with a tumour of the pelvis or sacrum?
Computer navigation-assisted surgery is safe and has reduced the intralesional resection rate for primary tumours of the pelvis and sacrum, and is recommended as being worthy of further consideration for this group of patients.
New Indications for Computer-Assisted Surgery: Tumor Resection in the Pelvis
Computer-assisted surgery is a potential method to increase the accuracy of tumor resections and was helpful for tumor identification in one patient with a recurrent presacral mesenchymal chondrosarcoma.
Precision tumour resection and reconstruction using image-guided computer navigation.
Six consecutive resections of musculoskeletal tumour in five patients using an existing commercial computer navigation system showed clear margins in all the tumour lesions and a resection that was exactly as planned.
Intraoperative Spinal Navigation
Intraoperative spinal navigation has advanced rapidly in recent years, beneficially affecting a variety of surgical procedures and future technological developments will widen its clinical application and minimize its shortcomings.
En bloc hemisacrectomy and internal hemipelvectomy via the posterior approach.
A posterior-only approach has the potential to complete an en bloc tumor resection and spinopelvic reconstruction while reducing surgical morbidity and the ability to perform a lumbosacral reconstruction, necessary in cases in which the S-1 body is iatrogenically disrupted during tumor resections.
[Osteochondroma and multiple osteochondromas: recommendations on the diagnostics and follow-up with special consideration to the occurrence of secondary chondrosarcoma].
The risk of malignant transformation of SO is generally low and MO patients seem to benefit from long-term follow-up: when the tumor is located in the trunk and in (proximal) long bones MRI or whole-body MRI, respectively, should be performed once a year after skeletal maturity because of the higher risk ofmalignant transformation in these patients.
