Summary
Percutaneous resection using CT guidance effectively treated osteoid osteoma in most patients. This minimally invasive technique offers a promising solution for osteoid osteoma, particularly in limb bones.
Area of Science:
- Orthopedic Surgery
- Musculoskeletal Oncology
- Minimally Invasive Procedures
Background:
- Osteoid osteoma is a benign bone tumor causing significant pain.
- Traditional treatments can be invasive and may lead to complications.
- Percutaneous techniques offer a less invasive alternative.
Purpose of the Study:
- To evaluate the efficacy and safety of percutaneous resection with a drill system under CT guidance for osteoid osteoma.
- To assess the feasibility of this technique in different skeletal locations.
Main Methods:
- Twenty-four patients with presumed osteoid osteoma underwent percutaneous resection using a 7-mm toothed drill under CT guidance.
- The drill was used to remove the nidus of the tumor.
- Follow-up included pain assessment and monitoring for recurrence.
Main Results:
- Twenty-three out of 24 patients (95.8%) were successfully treated.
- Histologic confirmation of osteoid osteoma was achieved in 19 cases.
- All treated patients remained pain-free and recurrence-free for 3-24 months.
- One patient required open surgery due to extensive bone resection.
Conclusions:
- Percutaneous resection with CT guidance is a highly effective treatment for osteoid osteoma, especially in the appendicular skeleton.
- The 7-mm drill size may pose challenges in small bones or delicate areas like the posterior vertebral arch.
- This technique is feasible and potentially the treatment of choice for osteoid osteoma in tubular bones and the femoral neck.
