Summary
Curettage with cryotherapy effectively treats aneurysmal bone cysts, offering good tumor control with low recurrence rates. This surgical approach avoids major bone reconstruction, improving patient outcomes.
Area of Science:
- Orthopedic Surgery
- Oncology
- Surgical Innovation
Background:
- Aneurysmal bone cysts (ABCs) are benign, expansile bone tumors requiring effective treatment.
- Surgical management of ABCs traditionally involves methods like curettage or resection, each with varying outcomes and complication rates.
Purpose of the Study:
- To evaluate the efficacy and safety of curettage combined with cryotherapy for treating aneurysmal bone cysts.
- To assess local tumor control, complication rates, and functional outcomes in patients undergoing this combined treatment.
Main Methods:
- A cohort of 26 patients with 27 aneurysmal bone cysts were treated with curettage and adjuvant cryotherapy.
- Follow-up evaluation included assessment of local recurrence, complications (wound infections, fractures), and functional outcomes over a mean period of 47 months.
Main Results:
- A single local recurrence was observed in one patient.
- Two patients experienced deep wound infections, and one patient sustained a postoperative fracture.
- The combination of curettage and cryotherapy demonstrated comparable results to marginal resection without necessitating major bony reconstruction.
Conclusions:
- Curettage with adjuvant cryotherapy is a recommended treatment for aneurysmal bone cysts, providing effective local tumor control.
- The addition of bone grafting to this surgical technique resulted in complete consolidation of the lesion in all treated patients.
- This minimally invasive approach offers a favorable alternative to more extensive surgical resections for aneurysmal bone cysts.
