Summary
Percutaneous CT-guided coaxial removal effectively treats osteoid osteoma in children. This minimally invasive technique offers a safe and successful option for pediatric bone tumor management.
Area of Science:
- Pediatric Orthopedics
- Minimally Invasive Surgery
- Radiology
Background:
- Osteoid osteoma is a benign bone tumor commonly affecting children and adolescents.
- Symptoms include pain, often worse at night and relieved by NSAIDs.
- Traditional treatments can be invasive, prompting the search for less invasive alternatives.
Purpose of the Study:
- To describe and evaluate a coaxial technique for percutaneous, CT-guided removal of osteoid osteoma in pediatric patients.
- To assess the safety and efficacy of this minimally invasive approach.
Main Methods:
- Eight children (3-15 years) with confirmed osteoid osteoma underwent CT-guided removal.
- A coaxial technique with a trephine was used for nidus removal.
- Power tools were incorporated in two cases; success was confirmed by postprocedural CT and histology.
Main Results:
- All eight CT-guided excisions were technically successful.
- Only one minor complication was reported.
- One recurrence at 13 months was successfully retreated percutaneously.
Conclusions:
- CT-guided coaxial removal is a safe and effective treatment for pediatric osteoid osteoma.
- Experience and use of power tools can optimize procedure time.
- This technique provides a viable minimally invasive option for osteoid osteoma management in children.
