Giant cell tumors of the bone can rarely develop after fracture fixation. Early recognition is key, and dual-energy CT can help overcome imaging challenges for effective treatment.
Area of Science:
- Orthopedic Surgery
- Oncology
- Radiology
Background:
- Distal radius fractures are commonly treated with volar locked plating.
- Giant cell tumors of the bone (GCTB) are typically found in the epiphyses of long bones.
Observation:
- A 77-year-old woman developed a GCTB 1.5 years after distal radius plating.
- Initial imaging showed plate prominence, with a large cavitary lesion discovered intraoperatively.
Findings:
- Histopathology confirmed GCTB.
- Wide en bloc resection and osteoarticular allograft reconstruction achieved local control.
Implications:
- GCTB is a rare but possible complication after fracture fixation.
- Dual-energy CT can aid in diagnosing GCTB obscured by metal artifact.
- Surgical resection and reconstruction offer effective local control for post-fracture GCTB.
