Percutaneous cryoablation for the treatment of osteoid osteoma in the adult population

Abstract

• CT-guided percutaneous cryoablation of osteoid osteoma is safe and effective • Cryoablation allows precise visual control of the aggregated iceball during procedure • Percutaneous cryoablation can be accomplished without general anaesthesia in selected cases • Another advantage of cryoablation is reduction of immediate postprocedural pain • Post-procedure MRI is helpful in the evaluation of technical success.

Misdiagnosis and treatment of proximal femoral osteoid osteoma

“…OO is a benign bone tumour with pain as the rst symptom accompanied by evident nocturnal pain and typical intra-cortical nidus surrounded by sclerosis and cortical thickening as the primary manifestation, which often requires surgical intervention [3,6,[21][22][23]. The proximal femoral constitutes the most susceptible part for OO, which is challenging to treat because of its deep location, close to the hip joint, and complex local anatomy [4,14,15,17,24]. Presently, the main surgical treatment methods for OO include open surgical resection and minimally invasive treatment, such as CT guided radiofrequency ablation (RFA) [25][26][27][28], cryoablation [17], and microwave ablation [29].…”

Whatever the kind of treatment adopted, the key to successful surgical treatment of OO is based on the accurate location of the nidus and its subsequent complete removal [3][4][5][6].…”

“…Minimally invasive surgery has the advantages of less trauma, precise location, and short operation time. However, it requires high hardware conditions, high technical operation requirements, presents with incomplete removal of the nidus, easy to damage adjacent tissues, and unable to carry out a pathological examination, and among other limitations, which affect its popularization and application [8,17,25,[30][31][32]. At the same time, minimally invasive surgery is signi cantly inferior to open surgical resection in terms of OO recurrence rate and incidence of complications [25,29,33,34].…”

“…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.…”

French Multidisciplinary Approach for the Treatment of MSK Tumors

“…OO and a small OB (1-3 cm) are generally treated with percutaneous thermoablation techniques all of which, including cryoablation (CA) [12][13][14] are effective, but laser ablation (LA) 15,16 and radiofrequency ablation (RFA) are the two most commonly used techniques. 17,18 LA is performed with a portable continuous wave semiconductor with an infrared diode laser (wavelength: 805 nm) connected to a flexible single-use bare-tipped 400-μm fiber with polymer cladding.…”
