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.
