Summary

Pelvic tumor resections require complex reconstruction. Local muscle flaps are effective for soft tissue defects, minimizing complications and ensuring successful outcomes in challenging oncologic cases.

Area of Science:

  • Orthopedic Oncology
  • Plastic Surgery
  • Reconstructive Surgery

Background:

  • Pelvic tumors, though rare, present significant oncologic and reconstructive challenges.
  • Post-resection, large soft tissue defects with exposed bone/joints and potential retroperitoneal defects are common.
  • Flap mobilization is crucial for eliminating dead space and covering exposed structures.

Purpose of the Study:

  • To evaluate immediate reconstruction outcomes after radical pelvic resections for tumors.
  • To analyze reconstructive modalities and their effectiveness in managing complex pelvic defects.

Main Methods:

  • Retrospective review of 11 patients undergoing radical pelvic resection and immediate reconstruction (1992-2002).
  • Multidisciplinary approach involving orthopedic oncology and plastic surgery teams.

  • Data collection on tumor type, resection extent, reconstruction method, complications, and outcomes.

    • Main Results:

    • Tumor types included chondrosarcoma, osteosarcoma, giant cell tumor, and carcinomas.
    • Reconstruction utilized rectus abdominis, gluteus maximus, and thigh fillet flaps.
    • Complications included flap loss, infection, and local recurrence; most cases had uneventful postoperative courses.

    Conclusions:

    • Soft tissue reconstruction after pelvic resection is complex, dictated by defect size and tissue availability.
    • Local pedicled muscle-based flaps are often sufficient for dead space elimination and wound closure.
    • Microvascular tissue transfer serves as a backup for cases lacking suitable local flap options.
