Radiofrequency Ablation Of Osteoid Osteoma Research Articles

Percutaneous radiofrequency coagulation of osteoid osteoma in children and adolescents.

The purpose of this paper was to evaluate the effectiveness of percutaneous radiofrequency ablation of osteoid osteoma in children and adolescents. Twenty-three patients aged 4.5-19.5 years were retrospectively reviewed. All patients with lower limb lesions were able to bear full weight on their operated limb immediately after the procedure, and to resume their daily activities within 24-48 h. Pain disappeared immediately after surgery in 21 cases, and in lower limb lesions the gait was back to normal after an average of 5 days. No septic or neurovascular complications were observed. At an average follow-up of 3.5 years, all the patients including two cases of initial failure were free of pain and had a normal gait. Clinical healing was confirmed by computed tomography and bone scan performed in 12 cases. This precise and minimally invasive method is safe, effective and associated with reduced health care resources. It could be recommended as the treatment of choice for osteoid osteoma of the limbs in children and adolescents.

Basic and clinical studies of percutaneous radiofrequency ablation ofosteoid osteoma using a standard electrosurgical generator

For percutaneous radiofrequency ablation of osteoidosteoma for pain management, we used a standardelectrosurgical generator instead of the radiofrequency generatorsystem. First, we used the standard electrosurgicalgenerator to determine the diameter of the coagulated areaof normal femurs and humeruses of dogs under generalanesthesia and to detect damage to normal tissue around thebone. We then used a standard electrosurgical generator toperform percutaneous radiofrequency ablation of the osteoidosteoma. All three patients were almost pain-free within thefirst 24 h after the procedure, and they were discharged theday after the operation, being hospitalized for only 2 days. Wethus confirmed that percutaneous radiofrequency ablationusing a standard electrosurgical generator produced resultssimilar to those achieved with the radiofrequency generatorsystem.

Image-guided Percutaneous Radiofrequency Ablation for Osteoid Osteomas

The authors present a retrospective analysis of the technical and clinical successes, complications, and clinical follow-up of image-guided percutaneous radiofrequency (RF) ablation of osteoid osteomas. Nine patients with osteoid osteomas underwent image-guided localization of osteoid osteomas. Outpatient percutaneous therapy (13 procedures) was performed under general anesthesia after image-guided localization of the nidus. Initial technical success was achieved in seven of nine patients. Two initial technical and clinical failures occurred early in this experience because of failure to adequately enter the nidus with use of fluoroscopic imaging alone. Clinical success was achieved in eight of nine patients. No major immediate or delayed complications were observed.

Percutaneous radiofrequency ablation in osteoid osteoma

We treated 58 patients with osteoid osteoma by CT-guided radiofrequency ablation (RF). In 16 it followed one or two unsuccessful open procedures. It was performed under general anaesthesia in 48, and spinal anaesthesia in ten. The nidus was first located by thin-cut CT (2 to 3 mm) sections. In hard bony areas a 2 mm coaxial drill system was applied. In softer areas an 11-gauge Jamshidi needle was inserted to allow the passage of a 1 mm RF probe into the centre of the nidus. RF ablation was administered at 90°C for a period of four to five minutes. Three patients had recurrence of pain three, five and seven months after treatment, respectively, and a second percutaneous procedure was successful. Thus, the primary rate of success for all patients was 95% and the secondary rate was 100%. One minor complication was encountered. CT-guided RF ablation is a safe, simple and effective method of treatment for osteoid osteoma.

Tratamiento percutáneo mediante radiofrecuencia del osteoma osteoide

ObjectiveTo present our initial experience in the treatment of osteoid osteoma by means of radiofrequency ablation. Material and methodsThree female patients, ranging between 5 and 19 years of age, were treated for tumors in proximal femur, tibia or calcaneus. General anesthesia was employed in two cases and conscious sedation in one. Computed tomography-guided imaging was used to introduce a trephine for placement of the electrode tip in the nidus. The electrode was connected to the radiofrequency generator for 8 minutes. ResultsPain disappeared within 48 hours in all three patients, none of whom required a hospital stay of more than 24 hours. Normal physical activity without restrictions was restored immediately after discharge. Three to four months later, the three patients remain asymptomatic.Percutaneous radiofrequency ablation of osteoid osteoma is an effective and safe approach that avoids the complications associated with surgery.

Percutaneous radiofrequency ablation of osteoid osteoma.

Osteoid osteoma is a benign bone tumor. Patients usually require surgical treatment for reliable pain relief. Difficulties with intraoperative localization of the tumor and anatomic locations that carry a high morbidity with en bloc resection complicate open surgery. Various methods have been developed to lessen the invasiveness of surgery including computed tomography-guided percutaneous radiofrequency thermal ablation. Eleven patients in three different centers were evaluated and diagnosed with osteoid osteoma based on typical histories, physical examinations, and imaging studies. All patients were treated with computed tomography-guided percutaneous radiofrequency thermal ablation after medical treatment failed. Excellent pain relief was reported in 10 patients. One patient suffered recurrence of a femoral neck lesion despite an initial 7-month period without pain. Patients were given a questionnaire to quantify the effectiveness of percutaneous radiofrequency ablation in terms of pain relief and return to function. The current study shows that percutaneous radiofrequency thermal ablation provides reliable, excellent pain relief and early return to function with minimal morbidity as compared with traditional open techniques. The authors suggest that this technique be used for all patients with extraspinal osteoid osteomas that are not immediately adjacent to neurovascular structures.
