[Ab] Resumo:Purpose To demonstrate that magnetic resonance (MR) imaging-guided high-intensity focused ultrasound (HIFU) is a safe, effective, and durable treatment option for the management of osteoid osteoma in children and young adults. Materials and Methods This prospective study was institutional review board approved and is registered with clinicaltrials.gov (identification number NCT02302651). Written informed consent was obtained from patients or their parents. Patients who had both clinical and radiologic findings that were diagnostic for nonvertebral osteoid osteoma and no contraindications to MR imaging-guided HIFU were enrolled between June 2010 and June 2013. The feasibility, safety, and clinical effectiveness of MR imaging-guided HIFU were considered primary outcomes; tumor control at imaging was considered a secondary outcome. Analyses were conducted on a per-protocol basis. Results Forty-five of the 50 recruited patients underwent MR imaging-guided HIFU. All patients were discharged without treatment-related complications. The median visual analog scale (VAS) pain score (scale, 0-10) decreased from 8 before treatment to 0 at 1-week and 1- , 6- , 12- , 24- , and 36-month follow-up. Similarly, median VAS scores for the degree to which pain interfered with sleep and physical and daily activities decreased to 0 within the 1st month after treatment and remained stable at subsequent follow-up. Overall, 39 (87%) of the 45 patients achieved and maintained a VAS score of 0 during the 3-year observation period. Quality of life, as assessed by using Functional Assessment of Cancer Therapy-Bone Pain (FACT-BP) scores (scale, 0-60 points), improved, with the median FACT-BP score of 28 (points) before treatment increasing to a median score of 55 at 1-week follow-up and 60 at 6-month and subsequent follow-ups. At (final) 36-month follow-up, MR imaging depicted an absence of residual nidus vascularity in 32 (76%) of the 42 patients who were treated with MR imaging-guided HIFU only. Conclusion The durable clinical efficacy and safety of MR imaging-guided HIFU were demonstrated. These features are evidence of the potential of MR imaging-guided HIFU to be part of a routine strategy for the treatment of osteoid osteoma. RSNA, 2017.

[Ab] Resumo:OBJECTIVE: To assess the long-term outcome of computed tomography-guided radiofrequency ablation (CT-guided RFA) in patients with suspected osteoid osteoma (OO). MATERIALS AND METHODS: Single-center retrospective study. Patients with clinical suspicion and imaging diagnosis of osteoid osteoma were treated by CT-guided RFA using the same device with either a 7- or 10-mm active tip electrode. Specific precautions were applied in case of articular or spinal OO. Patients were contacted by phone to evaluate the long-term outcome in terms of pain, ability to perform daily activities (including sports), and long-term complications. Success was defined as the absence of residual pain and ability to perform daily activities normally. RESULTS: From 2008 to 2015, 126 patients were treated by CT-guided RFA for OO in our institution. Mean patient age was 26.1 years (SD = 11, range 1-53); mean delay to diagnosis was 16.9 months (SD = 15.2, range 1-120). Among patients who answered the follow-up call (n = 88), the overall success rate was 94.3%: 79/88 (89.8%) had primary success of the procedure, and 4/88 (4.5%) had a secondary success (repeat-RFA after pain recurrence). Mean follow-up time was 34.6 months (SD = 24.7, range 3-90). Few complications occurred: two mild reversible peripheral nerve injuries, one brachial plexus neuropathy, one broken electrode tip fragment, and one muscular hematoma. CONCLUSION: Osteoid osteoma can be effectively and safely treated by CT-guided RFA using the presented ablation protocol. Beneficial effects of the treatment persist at long-term follow-up.

[Ab] Resumo:OBJECTIVE: To correlate dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) features to clinical and computed tomography (CT) morphological features of osteoid osteoma (OO). MATERIALS AND METHODS: Our institutional review board approved this retrospective study, waiving the need for informed consent. We included the 102 patients treated with interstitial laser ablation for histologically documented OO at our institution in 2008-2013. DCE-MRI variables were the time-enhancement pattern and rising slope (Slope ) and CT variables were the bone and segment involved (OO and OO respectively), OO location relative to the native cortex (OO ), nidus surface area, vessel sign, and largest neighboring-vessel diameter (Dmax ). Descriptive statistics and correlations linking DCE-MRI findings to clinical and CT characteristics were computed. RESULTS: DCE-MRI showed early arterial peak enhancement in 95 (93%) cases, with a mean Slope of 9.30 ± 8.10. CT visualized a vessel sign in 84 (82%) cases with a mean Dmax of 1.10 ± 0.60 mm. By univariate analysis, Slope correlated significantly with pain duration and Dmax (r = 0.30, P = 0.003; and r = 0.22, P = 0.03; respectively). Analysis of variance showed that Slope correlated significantly with OO (P < 0.001), with a steeper slope for OOs located in short or flat bones. CONCLUSION: This study suggests more abundant vascularization of OOs with long-lasting pain and location on short or flat bones.

[Ti] Título:Evaluation of accuracy and precision of CT-guidance in Radiofrequency Ablation for osteoid osteoma in 86 patients.

[Ab] Resumo:BACKGROUND AND PURPOSE: Osteoid osteoma is a benign skeletal tumour that accounts for 2-3% of all bone tumours. The male-to-female ratio is around 4:1 and it predominates in children and young adults. The most common symptom is pain, frequently at night-time. Historically the main form of treatment has been surgical excision. With the development of Radiofrequency Ablation (RFA) there is a percutaneus alternative. Success rates of RFA are lower but the main advantage is the minimal invasive character of the therapy and the low complication rate. As a result of the minimal invasiveness the hospitalization- and rehabilitation periods are relatively short. However, in current literature no values for accuracy and precision are known for the CT-guided positioning. METHODS: Accuracy and precision of the needle position are determined for 86 procedures. Furthermore the population is divided into groups based on tumour diameter, location and procedure outcome. RESULTS: The clinical success rate was 81.4%. In 79% of procedures complete ablation was achieved. Accuracy was 2.84 mm on average, precision was 2.94 mm. Accuracy was significantly lower in more profound lesions. Accuracy in tibia and fibula was significantly higher compared to the femur. No significant difference was found between different tumour diameters. INTERPRETATION: The accuracy and precision found are considered good. Needle position is of major importance for procedure outcomes. The question however rises how the results of this therapy will turn out in treatment of larger tumours.

[Ab] Resumo:Osteoid osteoma (OO) is a benign tumour that can cause severe pain and functional limitation to children and young adults; the treatment of choice is image-guided ablation. Due to the very small size of the lesion, detection and accurate needle placement may be challenging. Computed tomography (CT) offers very detailed imaging of the skeleton and is the modality of choice for the detection of small OO and for ablation guidance. Nevertheless, CT-guided positioning of the ablation applicator is linked to significant radiation exposure, particularly for the paediatric population. This case describes the successful use of a novel CT-based navigation system that offers the possibility of accurate ablation with only minimal radiation exposure in a paediatric patient.

[Ab] Resumo:Purpose of this study was to evaluate the employment of MRI-guided Focused Ultrasound (MRgFUS) for treatment of intra-articular benign bone lesions as alternative to surgery, and to monitor the success of the treatment on CT and MRI images. From March 2011 to August 2013, 14 intra-articular benign bone lesions were treated with MRgFUS. All patients were studied by CT and MR imaging. Pain was measured using the visual analogue scale (VAS) before and after treatment (6 and 12 months). All patients in our series demonstrated regression in painful symptomatology during screening. A significant drop in the mean VAS pain score (from 7.8 to 0.6) was observed at 12-month follow-up, and pain medication was no longer needed after treatment. No complications were observed. Three diagnostic imaging signs were found suggesting absence of biological activity and confirming the clinical findings: calcification of the treated lesion, lack of contrast enhancement and disappearance of bone oedema around the lesions. CONCLUSION: the employment of MRgFUS is safe and effective in the treatment of intra-articular benign bone lesions. The clinical outcome is satisfactory, and the success of the treatment is confirmed by diagnostic imaging.

[Ab] Resumo:BACKGROUND: Arthroscopic excision of an osteoid osteoma was first reported in the knee joint; since then, there have been several reports of arthroscopic excisions in the knee, shoulder, and elbow, with inconclusive outcomes because of a limited number of cases. The aim of this prospective study was to evaluate the medium-term functional effects of arthroscopic ablation in cases of an osteoid osteoma around the elbow. METHODS: We treated osteoid osteoma of the elbow through arthroscopic ablation in 10 patients. The arthroscopic resection procedure was performed 23 ± 9 months (range, 12-36 months) after initial symptoms. At the preoperative examination and last follow-up examination, the elbow flexion-extension and forearm supination-pronation ranges of motion were measured. The patients were assessed by the Mayo Elbow Performance Score, the visual analog scale for the elbow and wrist, and the Quick Disabilities of the Arm, Shoulder, and Hand score. Finally, the patients' general satisfaction was assessed. RESULTS: The postoperative elbow flexion-extension range of motion was significantly higher compared with range of motion before surgery (P = .001; r = 0.86). According to the Mayo Elbow Performance Score, the average score increased significantly at the final follow-up examination. The mean preoperative and final Quick Disabilities of the Arm, Shoulder, and Hand scores were 47 ± 14 and 1.6 ± 2.8, respectively (P < .001). All patients were satisfied with the operation result. CONCLUSION: According to the results of our study, arthroscopic ablation is a safe and efficient method of treatment for osteoid osteoma of the elbow, with a fast rehabilitation time.

[Ab] Resumo:Surgical excision is the traditional treatment for osteoid osteoma. However, the complexity of the foot anatomy makes a satisfactory outcome challenging. Difficulty in localizing the lesion intraoperatively may result in either incomplete tumor resection or excessive bone loss. To date, no published report has described the use of three-dimensional printing in the surgical treatment of osteoid osteoma of the calcaneus. In this case, we printed a three-dimensional model of the calcaneus of a 17-year-old female patient with a 2-year history of night pain in the lateral aspect of the hindfoot and ankle, evaluated the lesion as an osteoid osteoma, and designed a surgical guiding plate. Intraoperatively, we had no difficulty achieving complete resection of the lesion from the lateral calcaneus bone window, autogenous bone grafting, and subtalar arthrodesis. At the 2-year follow-up examination, the patient remained asymptomatic with no recurrence of the osteoid osteoma.

[Ab] Resumo:This article highlights that the long-term and serial follow-up of adolescents with osteoid osteoma should be considered, even after complete excision of the nidus owing to the possibility of the delayed onset or progression of femur head and neck deformities or osteoarthritis. It is important to recognize the sequelae of osteoid osteomas, such as bone edema and new bone formation, which can alter the normal anatomy of the proximal femur. We report two cases of osteoid osteoma in the proximal femur, which showed progressive hypertrophy of the femoral neck after excision of the nidus and subsequent cam-type femoroacetabular impingement (FAI), requiring additional osteochondroplasty procedures. Even though hip pain was relieved immediately after excision of the nidus in both cases, cam-type FAI developed during postoperative follow-up of 18 months (case 1) and 6.5 years (case 2). Hip pain subsided within 1 month of osteochondroplasty, and the full range of motion of the hip joint was achieved and was being maintained after postoperative follow-up of 1 year (case 1) and 6 months (case 2).

[Ab] Resumo:PURPOSE: To assess whether laser guidance can reduce fluoroscopy and procedure time of cone-beam computed tomography (CBCT)-guided radiofrequency (RF) ablations of osteoid osteoma compared to freehand CBCT guidance. MATERIALS AND METHODS: 32 RF ablations were retrospectively analyzed, 17 laser-guided and 15 procedures using the freehand technique. Subgroup selection of 18 ablations in the hip-pelvic region with a similar degree of difficulty was used for a direct comparison. Data are presented as median (ranges). RESULTS: Comparison of all 32 ablations resulted in fluoroscopy times of 365 s (193-878 s) for freehand and 186 s (75-587 s) for laser-guided procedures (p = 0.004). Corresponding procedure times were 56 min (35-97 min) and 52 min (30-85 min) (p = 0.355). The subgroup showed comparable target sizes, needle path lengths, and number of scans between groups. Fluoroscopy times were lower for laser-guided procedures, 215 s (75-413 s), compared to 384 s (193-878 s) for freehand (p = 0.012). Procedure times were comparable between groups, 51 min (30-72 min) for laser guidance and 58 min (35-79 min) for freehand (p = 0.172). CONCLUSION: Adding laser guidance to CBCT-guided osteoid osteoma RF ablations significantly reduced fluoroscopy time without increasing procedure time. LEVEL OF EVIDENCE: Level 4, case series.
