THR Using a 3D Printed Custom Made Acetabulum Component: A Case Report

Introduction: THR is one of the commonly performed adult arthroplasties in world. Over past 6 decades, Charnley low friction arthroplasty has evolved design and concept. One among those recent advances use 3D printing technology arthroplasties. Purpose this article to discuss share details a hip case where customized printed acetabulum component was used. Case: A 3 year postop fracture fixation presented with arthritis hip. CT revealed periacetabular massive bone loss. After considering all options, decision made shell. Discussion: Complex THRs special instrumentation augmented implants are frequently seen revision surgeries post cases. Based on size pattern defect, IlioIschial cages, Triflange cups, Trabecular metal augments, CupCage constructs, Jumbo cups some common options at surgeons disposal while tackling an loss challenge. manufactured can be aid when defect too large. It gives advantage being anatomically contoured. also allows porous structure for ingrowth. Conclusion: Life models pelvis explicit simulation surgery, including placement trajectory screws. This effective preoperative planning improve surgical precision reduce complications. Literature survival rates long term complications such 3d shells limited. Studies outcomes usage these would insightful Keywords: Printing, THR, Customised acetabular shell
