569 Resection of Massive Pelvic Chondrosarcoma Using Custom Made 3D Printed Jig: A Case Report

Abstract Background The pelvis is a complex structure associated with major neurovascular structures and so pelvic surgery can be challenging. In the field of skeletal tumours, surgeon's main aim to achieve adequate margins, which modern 3D printed technology assist with. Method A 43-year-old man was found have 20(CC) x 13(AO) 9.3(TR) cm chondrasarcoma at inner aspect right iliac bone. patient consented for sided type 1 hemipelvectomy tumour resection using customised Printed Jig. 64-slice spiral CT transferred an image processing software (Materialise Mimics 21.0 Materialise 3 Matic 13.0) generate model. Jig by FDM machine in ABS material sterilised. Incision made through standard ilioinguinal approach visualised. Soft tissue dissected over posterior Ilium placement jig then fixed k wire, following osteotomy done. Results Postoperatively had no complications. At final follow up 4 years, independently ambulant. Post op x-ray showed signs recurrence operated site. Conclusions This case highlights importance preoperative planning use surgical resection. Customised jigs help surgeons good resections R0 margins.
