Summary
This study shows that extended curettage with cryotherapy and bone grafting effectively treats aggressive chondroblastoma, significantly reducing local recurrence rates for this bone tumor.
Area of Science:
- Orthopedic Oncology
- Surgical Oncology
- Bone Tumors
Background:
- Chondroblastoma is an aggressive benign bone tumor.
- Local recurrence remains a significant challenge in chondroblastoma management.
- Existing treatments like curettage and bone grafting have limitations in preventing recurrence.
Purpose of the Study:
- To evaluate the efficacy of intraregional extended curettage combined with adjuvant cryotherapy and autogenous bone grafting for chondroblastoma.
- To assess the potential of this combined treatment to decrease the local recurrence rate.
- To analyze functional outcomes following this treatment protocol.
Main Methods:
- Patients underwent intralesional extended curettage.
- Adjuvant cryotherapy using liquid nitrogen was applied.
- Autogenous iliac crest bone grafting was performed.
- Follow-up included clinical and radiological assessments for healing and recurrence.
- Functional outcomes were measured using the Musculoskeletal Tumour Society (MSTS) scoring system.
Main Results:
- Mean follow-up was 49 months.
- Local recurrence rate was 7.1%.
- Average bone healing time was 7.4 months.
- Mean MSTS functional score was 92.7%.
- Complications included physeal growth arrest (14.3%) and superficial skin sloughing (7.1%).
Conclusions:
- The combination of extended curettage, cryotherapy, and autogenous bone grafting is a reliable treatment for chondroblastoma.
- This method achieves a low rate of local recurrence.
- The treatment provides good functional outcomes for patients with chondroblastoma.
