Summary
Wide local resection and prosthetic replacement offer excellent limb function for parosteal osteosarcoma. Recurrences were linked to biopsy methods, not treatment outcomes.
Area of Science:
- Orthopedic Surgery
- Oncology
- Bone Tumors
Background:
- Parosteal osteosarcoma is a rare bone tumor.
- Treatment often involves surgical resection.
- Prosthetic replacement is a reconstructive option.
Purpose of the Study:
- To evaluate the long-term outcomes of parosteal osteosarcoma treated with wide local resection and prosthetic replacement.
- To identify factors influencing recurrence and limb function.
Main Methods:
- Retrospective review of 20 parosteal osteosarcoma cases.
- Treatment involved wide local resection and prosthetic replacement.
- Follow-up ranged from six to 17 years.
Main Results:
- 85% of patients achieved excellent limb function.
- One patient developed pulmonary metastases (grade III histological disease).
- Four local recurrences were associated with biopsy practices and tumor encroachment.
Conclusions:
- Wide local resection and prosthetic replacement yield favorable limb function for parosteal osteosarcoma.
- Biopsy technique is critical to prevent local recurrence.
- Medullary invasion did not impact outcomes with this treatment approach.
