[Stable osteosynthesis following ilial resection in intraosseous Ewing sarcoma]

Area of Science:

• Orthopedic Oncology
• Surgical Reconstruction
• Bone Tumors

Background:

• Ewing's sarcoma is a rare bone cancer often affecting the pelvis.
• Surgical resection is a primary treatment modality for localized pelvic tumors.
• Reconstructing the os ilium after tumor removal presents significant biomechanical challenges.

Observation:

• A case report details a young male patient diagnosed with Ewing's sarcoma of the os ilium.
• The surgical approach involved en bloc resection of the affected os ilium and surrounding muscles.
• The pelvic defect was reconstructed using a double autogenous free fibula graft secured with a broad plate.

Findings:

• The reconstruction successfully restored bony stability of the pelvis.
• The patient was able to achieve full weight-bearing status post-surgery.
• No local recurrence or distant metastases were observed at the time of reporting.

Implications:

• This surgical technique offers a viable option for pelvic reconstruction after sarcoma resection.
• Autogenous fibula grafting provides a durable solution for large bone defects.
• Successful reconstruction facilitates early mobilization and improved functional outcomes for patients with pelvic Ewing's sarcoma.
