Use of 3D Printing in Orthopedic Oncology

Modern orthopedic oncology strikes a balance between two diametrically opposed approaches to treating cancer. On the one hand, total cancer removal including its “roots” in the surrounding tissue is guaranteed by maximal removal. On the other hand, it only eliminates as much as is required to keep the afflicted part’s function and appearance intact.

In this regard, 3-D printing, which creates three-dimensional objects as exact replicas of three-dimensional digital models by laying down the material in layers, has proven to be particularly useful for bone cancer surgery, both for thorough planning and for precisely carrying out that plan.

for meticulous planning and for carrying out that strategy properly.

In numerous ways, the use of 3D printing has helped bone cancer surgery. Orthopedic oncologists can now order joints and bones, starting with 3-D printed models of joints bearing tumors, to better comprehend the three-dimensional orientation of the tumor concerning the affected bone, especially for non-geometrically shaped bones like the pelvic bones, sacrum, and spine.

More accurate clinic radiological correlation has resulted from this, which benefits:

1- Better preoperative planning

2– Improved communication among operating team members

3- operational reference available

4-A greater comprehension of the needs of the surgeon by implant makers.

Intraoperative navigation is a significant additional application for 3D printing. The surgeon may not always correctly identify the location on the bone where they had planned the cut during bone cancer surgery, resulting in the removal of too much or too little bone. This issue has been resolved by 3-D printed “jigs,” which enable the surgeon to perform precise incisions in accordance with the preoperative plan after consulting with the radiologist. This is accomplished using a 3D-printed model and a jig with slots for the installation of cutting saw blades.

Making implants for reconstruction in limb salvage surgery using 3-D printing has proven to be extremely helpful, in addition to better preoperative planning and execution for resection. This is relevant to circumstances where we must order particular plates or specialized prosthetics that precisely fit the anatomical characteristics of the damaged bone, such as plates for fixation in young children.
