Radical resection of a tumor, specifically the innominate bone, is a surgical procedure primarily indicated for the removal of malignant neoplasms. However, it may also be necessary for benign tumors or those of indeterminate nature. The procedure begins with the creation of a skin incision directly over the tumor site, or alternatively, a skin flap may be elevated to provide access. Once the incision is made, the surgeon meticulously dissects the overlying tissue to expose the tumor. The entire innominate bone is then resected, which involves removing the tumor en bloc, meaning the tumor is excised along with a wide margin of surrounding healthy tissue to ensure complete removal. This radical approach is crucial as it encompasses the excision of all involved soft tissues, which can include muscles, tendons, fat, blood vessels, lymph vessels, nerves, and any tissues surrounding the joints that may be affected by the tumor. To confirm that the surgical margins are free of tumor cells, a separately reportable frozen section may be performed during the procedure. If any margins are found to contain malignancy, additional tissue will be excised until all margins are confirmed to be clear of tumor cells. Post-surgery, drains may be placed as necessary to manage fluid accumulation, and the surgical wound is typically closed in layers. In some cases, separately reportable reconstructive procedures may be performed to restore the area after the radical resection.
