BACKGROUND AND OBJECTIVES: The treatment of pelvic tumors, particularly in the periacetabular region (zone II of the Enneking and Dunham classification), represents a significant challenge for orthopedic oncologic surgeons due to the anatomical complexity and the need to preserve hip function. "Ice cream cone" prostheses have emerged as a promising reconstructive option due to their versatility and potential to reduce infection rates, although evidence regarding their effectiveness remains limited.
MATERIALS AND METHODS: A retrospective cohort of patients with pelvic bone tumors treated with "ice cream cone" prostheses between 2016 and 2023 at a single tertiary care center was analyzed. Patients with tumors affecting zone II and undergoing preservation of zone Ia were included. Surgical variables, complications, functionality, recurrence, and mortality were evaluated.
RESULTS: Ten patients met the inclusion criteria. The median age was 50 years, with a mean follow-up of 26.4 months. Chondrosarcoma was the most common tumor (60%). All surgeries achieved negative oncologic margins. The median postoperative score on the Musculoskeletal Tumor Society (MSTS) scale was 22.5 points (range: 12-28). No local recurrence was observed, although one patient developed metastases and another died due to complications of chronic kidney disease.
CONCLUSION: The use of "ice cream cone" prostheses for acetabular defects following oncologic resection appears to be a safe and effective technique in selected patients, offering good functional outcomes and high satisfaction, with complication rates comparable to other alternatives.
