Internal Hemipelvectomy for primary bone sarcomas using intraoperative patient specific instruments- the next step in limb salvage concept.

Background: During pelvic Sarcoma resections, Surgeons often struggle to obtain negative margins while minimizing collateral damage and maintaining limb function. These complications are usually due to the complex anatomy of the pelvis. Here we present an accurate 3D surgical approach, including pre-operative printing of models and intraoperative patient-specific instruments (PSIs) for optimizing pelvic sarcoma resections.

Inter and intra-observer agreement of the 3-dimensional CT based anterior inferior iliac spine classification system shows fair-to-moderate agreement among high volume hip surgeons.

Purpose: The purpose of this multicenter, multinational study is to evaluate the agreement level of the Hetsroni's classification system across high-volume hip surgeons who specialize in hip preservation surgeries.

Methods: Four surgeons from three countries reviewed a digital survey that included 93 3D CT images of the hip from 53 patients. The population was composed of individuals who had undergone a pelvis CT scan in a tertiary hospital between 2000 and 2016.

In situ cryoablation of sacral Giant Cell Tumor using three-dimensional (3D) model: A case report.

Three-dimensional planning of in-situ (-sacral) image guided cryoablation provides a method to treat sacral GCTs that accommodates the intricacies of the pelvis offering a safer, more efficacious alternative. Here we report on IM a 23-year-old female with a sacral GCT. She presented to Tel Aviv Medical Center with ongoing pain as well as neurological symptoms.
