Surgeons can now preoperatively assess wound complication risk using a newly validated scoring model for internal hemipelvectomy.

• Wound complications requiring surgery occurred in 34% of patients overall, with rates of 7.4%, 40%, and 67% in low-, intermediate-, and high-risk groups in the training cohort.
• Similar results were observed in the validation cohort: 7.1%, 32%, and 49% in respective risk groups.

Identifying high-risk patients preoperatively allows for tailored surgical approaches and potential reconstruction strategies for better outcomes.
