Clinical Scorecard: Cost-effective Reconstruction Using a 3D-Printed Cement Spacer in a Unique Case of Calcaneal Ewing Sarcoma: A Case Study and Surgical Approach

At a Glance

Key Highlights

• Ewing sarcoma accounts for 15% of primary bone tumors, primarily affecting children and young adults.
• Involvement of the foot is rare, representing only 5% of cases.
• Neoadjuvant chemotherapy followed by limb salvage surgery was performed in a 19-year-old female patient.
• Reconstruction utilized a custom 3D-printed cement spacer due to logistical constraints.
• The patient experienced a deep surgical site infection managed by debridement and implant removal.

Guideline-Based Recommendations

Diagnosis

• Histopathological confirmation of Ewing sarcoma is essential.

Management

• Neoadjuvant chemotherapy followed by limb salvage surgery is recommended for non-metastatic cases.

Monitoring & Follow-up

• Regular follow-up for signs of recurrence or metastasis is necessary.

Risks

• Potential for surgical site infections and complications related to reconstruction.

Patient & Prescribing Data

Young adults with non-metastatic Ewing sarcoma.

Combination chemotherapy regimen included Vincristine, Doxorubicin, Cyclophosphamide, Ifosfamide, and Etoposide.

Clinical Best Practices

• Utilize multidisciplinary tumor board discussions for treatment planning.
• Consider 3D printing technology for personalized surgical reconstruction.
• Monitor for complications post-surgery, including infections.
