Bernese Periacetabular Osteotomy in a Hip Extra-Articular Resection Followed by Reconstruction Using an Extracorporeal Irradiated Acetabulum Autograft with Megaprosthesis, for Proximal Femur Osteosarcoma in a Pediatric Patient

Figure 2

Following the Bernese periacetabular osteotomy, an en bloc extra-articular resection of the acetabulum was performed; the resected specimen was then transferred to a separate sterile trolley. A capsulectomy was made through the acetabular rim, and the articular fluid and proximal femur were sent for histological examination. The acetabulum was placed in a sterile container and sent to the radiotherapy department for extracorporeal irradiation.
