The combination of percutaneous vertebroplasty with radiofrequency ablation (verteblation) has not shown to be an effective measure of pain management in patients with metastatic lesions of the spine. The use of this novel technique has not been previously described in metastatic disease from thyroid cancer. We would like to report our experience after treating a patient affected by a thyroid carcinoma and an osteolytic spine metastasis. The patient suffered from life-limiting pain and was successfully treated with a combination of vertebroplasty and radiofrequency ablation...

INTRODUCTION: By using a combination of magnetic resonance imaging (MRI) and computed tomography (CT) of the lumbar spine, it is possible to distinguish between spinal stenosis caused by bone compression and specific soft tissue epidural intraspinal lesions that cause localized spinal canal stenosis and neural compression. Examples include facet cysts and yellow ligament hypertrophy. Many of these patients are elderly with medical comorbidities that make open surgery problematic. MATERIALS & METHODS: This is a study of patients with predominantly soft tissue stenosis being treated with targeted intraspinal radiofrequency (RF) heat ablation...

BACKGROUND: Treatment of spinal metastatic lesions by radiofrequency ablation (RFA) before cementation can potentially help in local tumor control and pain relief. This is often limited by access and tumor location. This study reports multicenter clinical and imaging outcomes following targeted RFA (t-RFA) and cement augmentation in neoplastic lesions of the spine. MATERIAL AND METHODS: A retrospective multicenter study of 49 patients with 72 painful vertebral lesions, evaluated for clinical and imaging outcomes following RFA and cement augmentation of spinal metastatic lesions, was undertaken...

INTRODUCTION: A small subset of patients who underwent successful vertebral compression fracture (VCF) augmentation procedures may develop subsequent pain requiring spinal injections. In a retrospective analysis, we determined whether the pain was related to the original fracture site or to another area within the lumbar or thoracic spine. The pain occurred either at the same/adjacent level and/or non-adjacent level as the VCF. Interventional treatments primarily targeted the facet joints, specifically in the form of facet joint blocks and/or radiofrequency ablation to the medial branches...

In order to provide effective options for minimally invasive treatment of spinal metastases, the present study retrospectively evaluated the efficacy and safety of image-guided minimally invasive percutaneous treatment of spinal metastases. Image-guided percutaneous vertebral body enhancement, radiofrequency ablation (RFA) and tumor debulking combined with other methods to strengthen the vertebrae were applied dependent on the indications. Percutaneous vertebroplasty (PVP) was used when vertebral body destruction was simple...

Pudendal neuralgia (PN) is a result of pudendal nerve entrapment or injury, also called "Alcock syndrome." Pain that develops is often chronic, and at times debilitating. If conservative measures fail, invasive treatment modalities can be considered. The goal of this case report is to add to a small body of literature that a pulsed radiofrequency (PRF) ablation can be effectively used to treat PN and to show that high resolution MR neurography imaging can be used to detect pudendal neuropathy. CASE PRESENTATION: We present a case of a 51-year-old woman with 5 years of worsening right groin and vulva pain...

A 25-year-old man presented with chronic low back pain and occasional radiation to the right lower limb. Magnetic resonance imaging and computed tomography (CT) of the lumbar spine showed an osteolytic expansile lesion with a central sclerotic nidus in the right superior facet of the L5 vertebra and surrounding marrow oedema. The diagnosis of osteoblastoma was made based on imaging findings and confirmed after CT-guided biopsy. Radiofrequency ablation of the lesion was successfully performed. The patient tolerated the procedure well and showed symptomatic relief...

Minimally invasive percutaneous imaging-guided techniques have been shown to be safe and effective for the treatment of benign tumors of the spine. Techniques available include a variety of tumor ablation technologies, including radiofrequency ablation, cryoablation, microwave ablation, alcohol ablation, and laser photocoagulation. Vertebral augmentation may be performed after ablation as part of the same procedure for fracture stabilization or prevention. Typically, the treatment goal in benign spine lesions is definitive cure...

PURPOSE: Occipital neuralgia is a condition wherein pain is transmitted by the occipital nerves. Non-invasive therapies generally alleviate symptoms; however, persistent or recurring pain may require invasive procedures. Repeated invasive procedures upon failure are considered higher risk and are often contraindicated due to compounding inherent risk. SRS has not been explored as a treatment option largely due to the extracranial nature of the target (as opposed to the similar, more established trigeminal neuralgia), but advances in linear-accelerator frameless-based SRS now present an opportunity to evaluate the novel potential of this modality for this application...

Diffuse Idiopathic Skeletal Hyperostosis (DISH) can cause ossification of ligaments and may affect the spine. We report a case of obstructive sleep apnea in a patient with significant upper airway narrowing secondary to cervical DISH. This patient had an initial apnea-hypopnea index (AHI) of 145 events/hour and was treated with uvulopalatopharyngoplasty, genial tubercle advancement, hyoid suspension, septoplasty, inferior turbinoplasties, and radiofrequency ablations to the tongue base which reduced his AHI to 40 events/hour...

The ROSA® robot (Medtech, Montpellier, France) is a new medical device designed to assist the surgeon during minimally invasive spine procedures. The device comprises a patient-side cart (bearing the robotic arm and a workstation) and an optical navigation camera. The ROSA® Spine robot enables accurate pedicle screw placement. Thanks to its robotic arm and navigation abilities, the robot monitors movements of the spine throughout the entire surgical procedure and thus enables accurate, safe arthrodesis for the treatment of degenerative lumbar disc diseases, exactly as planned by the surgeon...

Radiofrequency ablation is a valuable tool in the treatment of many diseases, especially cancer. However, controlled heating up to apoptosis of the desired target tissue in complex situations, e.g. in the spine, is challenging and requires experienced interventionalists. For such challenging situations a mathematical model of radiofrequency ablation allows to understand, improve and optimise the outcome of the medical therapy. The main contribution of this work is the derivation of a tailored, yet expandable mathematical model, for the simulation, analysis, planning and control of radiofrequency ablation in complex situations...

Osteoid osteoma (OO) is a benign bone tumor, with a male-female ratio of approximately 2:1 and mainly affecting long bones. Ten percent of the lesions occur in the spine, mostly within the posterior elements. Treatment options for OO include surgical excision and percutaneous imaging-guided radiofrequency ablation (RFA). Lesions within the spine have an inherent risk of thermal damage to the vital structure because of proximity to the neural elements. We report a novel use of the epidural catheter for air injection for the neuroprotection of nerves close to the OO of the spine...

BACKGROUND: Hepatic resection (HR) of metastatic neuroendocrine cancer has been associated with prolonged survival and durable symptom control for selected patients with metastatic neuroendocrine tumor (NET). The present study investigates the outcomes of this operative approach in selected patients with known bone metastases. METHODS: All patients undergoing HR at Mayo Clinic Rochester and Mayo Clinic Florida for metastatic NET between January 1989 and August 2015 were identified, and were divided into two groups: those undergoing HR with a known diagnosis of bone metastases (HRmNET/LB) and those who had metastatic disease confined to the liver (HRmNET/L)...

Metastatic epidural compression of the spinal cord is a significant source of morbidity in patients with systemic cancer. With improvment of oncotheray, survival period in the patients is improving and metastatic cord compression is en- countered increasingly often. Surgical management performed for early circumferential decompression for the spinal cord com- pression with spine instability, and spine reconstruction performed. Patients with radiosensitive tumours without spine instabili- ty, radiotherapy is an effective therapy...

BACKGROUND: Zygapophysial joint arthrosis is a pathology related with axial lumbar pain. The most accepted treatment, after failure of medical management, is the thermal denervation of the medial branch. Nonetheless, the placement of the heat probe remains a challenge to surgeons, even when using the fluoroscope. Using a variation of Shealy's and Bogduk's original techniques, which includes ablation of the medial branch and the nerves present in the joint capsule, we hypothesize that we can obtain similar outcomes to those found in the literature...

BACKGROUND: Liposarcoma is a malignant tumor of soft tissue. Myxoid/round cell liposarcoma has a tendency to spread to extrapulmonary sites but the spine is an unusual location even for metastasis. Metastatic bone tumors in the spine are painful. The vertebral body augmentation procedures for treating painful metastatic spinal lesions are minimally invasive and are good alternatives to open surgery. CASE PRESENTATION: A 41-year-old Turkish man was treated with radiofrequency tumor ablation and percutaneous vertebral augmentation for spinal metastasis...
