Summary
Minimally invasive CT-guided excision of osteoid osteomas offers effective pain relief. This technique, often combined with sclerotherapy, provides a safe alternative to open surgery, especially for hip lesions.
Area of Science:
- Orthopedic Surgery
- Oncology
- Radiology
Background:
- Osteoid osteomas present with significant pain and reactive bone changes.
- Their small size allows for minimally invasive treatment approaches.
Purpose of the Study:
- To evaluate the efficacy of percutaneous CT-guided nidus excision for osteoid osteomas.
- To assess the outcomes of additional sclerotherapy for residual tumors.
Main Methods:
- Ten patients with symptomatic osteoid osteomas underwent percutaneous CT-guided nidus excision using a 3-mm Harlow-Wood needle.
- Seven patients with residual tumor were treated with thermocautery or ethanol sclerotherapy.
Main Results:
- Six patients experienced immediate and sustained pain relief over 3 years.
- Two patients required a second transcutaneous intervention for successful treatment.
- Only two patients necessitated open resection.
Conclusions:
- Percutaneous CT-guided enucleation with sclerotherapy is a viable alternative to open resection for osteoid osteomas.
- This minimally invasive approach is particularly advantageous for lesions near the femoral neck, avoiding risks associated with open surgery.
