Summary
This study details a rare case of Ewing sarcoma in a young boy's finger. Surgical reconstruction using ray transfer achieved excellent hand function and acceptable appearance post-treatment.
Area of Science:
- Orthopedic Oncology
- Skeletal Tumors
- Pediatric Oncology
Background:
- Ewing sarcoma is a rare bone cancer primarily affecting children and young adults.
- Primary Ewing sarcoma of the phalanx is exceptionally uncommon, posing unique treatment challenges.
Observation:
- An 18-year-old male presented with primary Ewing sarcoma of the proximal phalanx of the right middle finger.
- Treatment involved neoadjuvant chemotherapy followed by ray amputation of the affected digit.
Findings:
- A novel surgical approach involved transferring the index ray to the base of the third metacarpal bone.
- The transferred ray was secured using a plate fixation.
- Post-operative assessment revealed excellent functional recovery and acceptable cosmetic outcome.
Implications:
- This case demonstrates the potential for successful limb salvage and functional restoration in rare pediatric bone sarcomas.
- Ray transfer surgery offers a viable reconstructive option for maintaining hand function after digit amputation.
- Further research into optimizing surgical techniques for digital Ewing sarcoma is warranted.
