Purpose: To evaluate the safety and effectiveness of lateral or posterolateral percutaneous vertebroplasty (PVP) of osteolytic C1-C2 lesions performed under computed tomography (CT) guidance and local anesthesia.

Materials And Methods: A retrospective study of 16 consecutive patients (11 females and 5 males; aged from 24 to 86 years; median age, 65.5 years) who underwent 17 lateral or posterolateral PVP was performed.

Comparison of false starts by saw created on flesh and dry bones; as close as possible to the real conditions of criminal dismemberment.

In most experimental protocols, false starts are produced on dry bones obtained through a maceration process for anthropological analyses, for the sake of reproducibility. Although this allows for controlled experimental conditions, the absence of soft parts when experimentally creating false starts does not correspond to the real conditions of criminal dismemberment. The main objective of this study was to determine if the results of experimental work on the characteristics of false starts were valid under medico-legal conditions.

Combined vertebroplasty and pedicle screw insertion for vertebral consolidation: feasibility and technical considerations.

Purpose: To assess the feasibility and technical accuracy of performing pedicular screw placement combined with vertebroplasty in the radiological setting.

Methods: Patients who underwent combined vertebroplasty and pedicle screw insertion under combined computed tomography and fluoroscopic guidance in 4 interventional radiology centers from 2018 to 2023 were retrospectively assessed. Patient demographics, vertebral lesion type, and procedural data were analyzed.

CT-Guided Percutaneous Vertebroplasty for Vertebral Non-union Following Posterior Fixation: A Preliminary Retrospective Study.

Purpose: Traumatic thoracolumbar vertebral fractures are frequently treated with posterior fixation (PF) and vertebral augmentation. Sometimes, it is deemed too risky to offer vertebral augmentation under fluoroscopic guidance alone. Adjuvant CT/fluoroscopy-guided percutaneous vertebroplasty (PVP) could be offered in certain scenarios.

Purpose: To evaluate the technical efficacy, safety, and reproducibility of automated percutaneous lumbar discectomy (APLD) under CT and fluoroscopic guidance, for treating radiculopathy caused by lumbar disc herniation in patients impervious to conservative treatment.

Methods: A total of 77 patients with symptomatic lumbar disc herniation were treated with APLD in a prospective multicentric study performed in four centers across three countries. Magnetic resonance imaging and/or computed tomography was used to evaluate the disc herniation before and after the procedure.

Percutaneous cementoplasty of periprosthetic loosening: can interventional radiologists offer an alternative to revision surgery?

Objective: To evaluate feasibility and validate both safety and efficiency of radiological percutaneous periprosthetic bone cementoplasty (RPPBC) performed under local anesthesia as an alternative minimally invasive treatment of aseptic implant loosening.

Methods: In this case series, seven patients (mean age 81 years, range 73 to 89 years, 2 men and 5 women) were enrolled between February 2011 and January 2020 with confirmed aseptic loosening of orthopedic implants. One patient presented with tibial component loosening of an unicompartmental knee arthroplasty, one with glenoid component loosening from a reverse shoulder arthroplasty, one femoral gamma nail, and four presented with pedicle screw loosening after staged posterior lumbar interbody fusion.

An unusual Staphylococcus saccharolyticus spondylodiscitis post kyphoplasty: a case report.

Background: Staphylococcus saccharolyticus is a rarely encountered coagulase-negative, which grows slowly and its strictly anaerobic staphylococcus from the skin. It is usually considered a contaminant, but some rare reports have described deep-seated infections. Virulence factors remain poorly known, although, genomic analysis highlights pathogenic potential.

Endovascular Occlusion of Neovascularization as a Treatment for Persistent Pain After Total Knee Arthroplasty.

Approximately 20% of patients have persistent unexplained pain after total knee arthroplasty (TKA). Currently available treatments are unsatisfactory. The present report describes four patients in whom transcatheter arterial embolization had a remarkable effect on pain after TKA.

Innovative Spine Implants for Improved Augmentation and Stability in Neoplastic Vertebral Compression Fracture.

Tumor-related vertebral compression fractures often result in severe back pain as well as progressive neurologic impairment and additional morbidities. The fixation of these fractures is essential to obtain good pain relief and to improve the patients' quality of life. Thus far, several spine implants have been developed and studied.

Objective: The purpose was to evaluate, in a cadaveric cohort, the feasibility and the learning curve of ultrasound-guided percutaneous carpal tunnel release.

Materials And Methods: Fourteen carpal tunnel releases were carried out on unembalmed cadavers by a senior and a junior radiologist. Procedures were realized with an 18-MHz linear probe.

Five simultaneous artificial intelligence data challenges on ultrasound, CT, and MRI.

Purpose: The goal of this data challenge was to create a structured dynamic with the following objectives: (1) teach radiologists the new rules of General Data Protection Regulation (GDPR), while building a large multicentric prospective database of ultrasound, computed tomography (CT) and MRI patient images; (2) build a network including radiologists, researchers, start-ups, large companies, and students from engineering schools, and; (3) provide all French stakeholders working together during 5 data challenges with a secured framework, offering a realistic picture of the benefits and concerns in October 2018.

Materials And Methods: Relevant clinical questions were chosen by the Société Francaise de Radiologie. The challenge was designed to respect all French ethical and data protection constraints.

Serious Neurological Complication Resulting from Inadvertent Intradiscal Injection During Fluoroscopically Guided Interlaminar Epidural Steroid Injection.

We describe the case of a 30-year-old patient who was referred for lumbar epidural corticosteroid injection due to right L5 radiculopathy. Two months earlier, MRI demonstrated a right large paracentral L4-L5 disk extrusion causing disabling L5 radiculopathy. The L4-L5 level was selected for interlaminar injection, using fluoroscopic guidance.

Contained Herniated Lumbar Disc: CT- and Fluoroscopy-Guided Automated Percutaneous Discectomy-A Revival.

The combination of a new device and dual guidance (computed tomography [CT] and fluoroscopy) is similar to other percutaneous devices in achieving a mechanical decompression of the disc. The difference, however, is that the target of the decompression with the current technique is the herniated disc itself. The goal of this combined technique is to create a space, an "olive" around the probe, allowing a decrease in pressure inside the hernia.

Percutaneous vertebroplasty in tumoral spinal fractures with posterior vertebral wall involvement: Feasibility and safety.

Purpose: to evaluate the technical feasibility and safety of CT and fluoroscopy guided percutaneous vertebroplasty in the treatment of tumoral vertebral fractures with posterior wall involvement.

Materials And Methods: Institutional review board approval and informed consent were obtained for this study. Sixty-three consecutive adult patients (35 women, 28 men; mean age+/- standard deviation: 69 years+/- 14) with tumoral spinal fractures that compromised the posterior wall were treated by means of percutaneous vertebroplasty with CT and fluoroscopy guidance.
