“…As far as gas dissection is concerned, it can also help in the protection of the neural elements, due to its insulating effect and increase in distance between the probe and the spinal cord. The use of air as well as carbon dioxide insulation [3][4][5] has been successfully demonstrated, with RFA. However, the literature on the use of air/carbon dioxide insulation with MWA for spinal osteoid osteoma is extremely scarce.…”

“…Carbon dioxide is considered a superior protective agent than air for thermal ablation, as it is a better insulator than air and is less soluble than air (reducing the chances of air embolism). 4 5 However, specialized prefilled syringes are required for using carbon dioxide, which are not available at our institution. Nevertheless, there have been no reports of air embolism with such minute quantities of air injected epidurally under imaging guidance.…”

Osteoid osteomas are benign tumors seen in children and young adults. The management options include surgical resection and percutaneous ablation. In the present scenario, percutaneous ablation is the preferred modality, as it is minimally invasive, safe, and reliable. However, when the tumor is near a heat-vulnerable structure, thermal injury can occur.We report the case of spinal osteoid osteoma in a young female that was treated by microwave ablation (MWA) with air insulation to prevent heat injury to the spinal cord. Currently, there is paucity of literature describing the use of air insulation with MWA. In this report, we describe the technique, advantages, and limitations of using air insulation with MWA.

“…Folglich können Tumore, die von kortikalem Knochen umgeben sind oder einen Mindestabstand von 1 cm von neuralen Strukturen aufweisen, ohne protektive Maßnahmen mit RFT behandelt werden. Der Liquorfluss hat durch den Abtransport von Temperatur ebenfalls eine protektive Wirkung, so dass neurale Strukturen, die von Liquor umgeben sind, eine höhere Toleranz gegenüber Temperaturwirkung haben [13]. Bei fehlender kortikaler Umgebung und einem Abstand von weniger als 1 cm zum Nervengewebe können diese durch eine simultane perineurale Umspülung mit Kochsalz [14] oder Luftinsufflation [15] gegenüber der schädigenden Temperaturwirkung geschützt werden.…”

ZusammenfassungOsteoidosteome und Osteoblastome sind gutartige knochenbildende Tumore, die in den ersten beiden Lebensdekaden nicht selten die Ursache von schmerzhaften Läsionen der Wirbelsäule mit schmerzbedingter skoliotischer Deformierung sind. Beide Entitäten sind sich histologisch sehr ähnlich, lassen sich jedoch durch Röntgen bzw. computertomographische Darstellung anhand ihrer Größe und morphologischen Merkmale gut differenzieren. Die Osteoblastome können durch ihre Größenzunahme und osteodestruktives Verhalten die Wirbelsäule destabilisieren oder zu neurologischen Ausfälle führen. Die Schmerzen sprechen häufig gut auf die Nicht Steroidale AntiRheumatika (NSAR), insbesondere auf Azetylsalezylsäure, an. Schmerzpersistenz und Nebenwirkungen von NSAR sowie mögliche Instabilitäten erfordern aber häufig eine interventionelle Therapie mit chirurgisch vollständiger Resektion selten in Kombination mit Stabilisierung oder perkutane Radiofrequenzablation, die je nach morphologischen Gesichtspunkten angewendet werden können.

“…There are still some controversies over the treatment of proximal femoral OO considering the particular location of the nidus. Open surgical resection and minimally invasive radiofrequency ablation also have their own advantages [13][14][15][16][17][18]. Therefore, this study introduces our bone tumor center's experience in the diagnosis and treatment of OO of the proximal femur in detail, and de nes the potential pitfalls in the diagnosis and treatment process, so as to realize the rapid and accurate diagnosis and optimize the treatment strategy of OO of the proximal femur.…”

Aims: Herein, we examined the efficacy of open resection in proximal femoral osteoid osteoma (OO) treatment. Besides, we analysed the causes of misdiagnosis of proximal femoral OO to provide a reference for its diagnosis and treatment.Methods: This was a retrospective study involving 29 patients with proximal femoral OO admitted into our hospital from January 2010 to January 2018. The baseline characteristics of the participants included; 21 males and 9 females, aged between 13 to 25 (mean 16.2) years old, and the course of the disease was 1 to 14 (mean 6.1) months. We used previous medical experience records of the patients to analyze for the causes of misdiagnosis. Moreover, we compared the difference between preoperative and postoperative treatment practices in alleviating pain in OO patients and restoring hip function. Follow-ups were conducted regularly, and patients advised to avoid strenuous exercises for 3 months.Results: We followed up 29 patients (21 intercortical, 2 sub-periosteal, and 6 medullary) for an average of 42.5 months. We found that 13 patients (44.8%) had been misdiagnosed of synovitis, Perthes disease, osteomyelitis, intra-articular infection, and joint tuberculosis, whose average time from symptoms to diagnosis were 9.8 months. Postoperative pain score and joint function score improved significantly compared with preoperative, and complications were rare.Conclusion: Open surgical resection constitutes an effective treatment for proximal femoral OO by accurately and completely removing the nidus. Lack of understanding, wrong choice of examination, and the complexity and diversity of clinical manifestations constitute the main reasons for the misdiagnosis of proximal femoral OO.
