Objectives: To assess the technical success of trans-isthmic screw fixation with simultaneous CT and fluoroscopic guidance in patients with symptomatic low-grade isthmic spondylolisthesis.

Methods: Fifty patients (28 women and 22 men; mean age ± standard deviation: 50 years ± 18.9) presenting with symptomatic low back pain with isthmic spondylolisthesis refractory to medical management were treated by means of trans-isthmic pars interarticularis percutaneous screw fixation.

Percutaneous discectomy under CT and fluoroscopy guidance: an international multicentric study.

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.

CT-guided fixation of pelvic fractures after high-energy trauma, by interventional radiologists: technical and clinical outcome.

Objective: The aim of our study was to evaluate screw placement accuracy, safety, complications, and clinical outcomes including functional and pain score, in 32 patients treated with CT-guided pelvic ring fixation after high-energy trauma.

Materials And Methods: Consecutive patients who were treated by CT-guided fixation of sacral or acetabular fractures after high-energy trauma were included. All procedures were performed under general anesthesia, with dual CT and fluoroscopic guidance, by interventional radiologists.

Ultrasound-guided percutaneous release of the carpal tunnel: comparison of the learning curves of a senior versus a junior operator. A cadaveric study.

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.

Symptomatic Schmorl's nodes: role of percutaneous vertebroplasty. Open study on 52 patients.

Purpose: To assess the feasibility and clinical outcome of combined CT and fluoroscopy-guided percutaneous vertebroplasty in the management of painful Schmorl's nodes (SN).

Methods: A prospective study was carried out from January 2014 to January 2016 in 52 consecutive patients. Thirty-two men and 30 women aged between 42 and 88 years old were consecutively included.

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.

Cosmetic Adolescent Filler: An Innovative Treatment of the "Selfie" Complex.

Purpose: "Selfie" photography is increasing among teenagers, accentuates congenital anomalies, and impacts self-confidence. Tear trough deformity is most commonly due to aging, but also occurs as a congenital anomaly and can be a major source of insecurity and embarrassment.

Objective: The purpose of this study is to show the efficacy and safety of hyaluronic acid gel filler in a teenage patient with congenital tear trough deformity.

Percutaneous vertebroplasty under local anaesthesia: feasibility regarding patients' experience.

Objective: Evaluate patients' intraoperative experience of percutaneous vertebroplasty (PV) performed without general anaesthesia in order to assess the feasibility of local anaesthesia and simple analgesic medication as pain control protocol.

Methods: Ninety-five patients who underwent single-site PV were consecutively included in the study between 2011 and 2013. Each procedure was achieved under local anaesthesia and perfusion of paracetamol, tramadol and dolasetron, with combined CT and fluoroscopy guidance.

[Imaging of bone metastases].

Bone metastases are detected at initial diagnosis of cancer in 25% of cases and bone metastases are common in the course of a majority of cancer types. The spine and proximal long bones are the most affected sites. Knowledge of the basic radiological semiology is important to make the proper diagnosis of metastasis(s) bone(s), especially in situations in which the clinical context is not suggestive of metastases (such as cases where bone metastases are inaugural or cases of peripheral solitary metastasis).

Vertebral split fractures: technical feasibility of percutaneous vertebroplasty.

Objective: The treatment of vertebral split fractures remains controversial, consisting of either corset or internal fixation. The aim of this study was to evaluate the technical feasibility of CT- and fluoroscopy-guided percutaneous vertebroplasty in the treatment of vertebral split fractures.

Materials And Methods: Institutional review board approval and informed consent were obtained for this study.

CT quantification of hemoperitoneum volume in abdominal haemorrhage: a new method.

Introduction: In emergency departments, focused assessment for sonographic examination of trauma patients (FAST) accurately detects hemoperitoneum in unstable patients. Currently, only an approximation of the volume of free intraperitoneal fluid (FIPF) can be done using ultrasound (US) and CT scans. We previously reported a new method developed on an experimental cadaveric model using US examination of the abdomen and applying a mathematic formula to effusion measurements to evaluate the exact volume of FIPF.

Symptomatic lumbar facet joint cysts treated by CT-guided intracystic and intra-articular steroid injections.

Objective: To evaluate percutaneous computed tomography (CT)-guided intracystic and intra-articular steroid injections for the treatment of lumbar facet joint cyst causing radicular pain.

Methods: A single-centre prospective study involving 120 consecutive patients with symptomatic lumbar facet joint cyst-induced radicular pain was done (72 women, 48 men). The average age was 68.

CT- and fluoroscopy-guided percutaneous discectomy for lumbar radiculopathy related to disc herniation: a comparative prospective study comparing lateral to medial herniated discs.

Objective: To evaluate and compare two groups of patients with sciatica due to intervertebral disc herniation with no neurologic deficit. The groups consisted of patients with intervertebral disc herniation in a medial location (group 1) and those in a lateral location (group 2).

Materials And Methods: A total of 200 patients were included in the study and were followed for a minimum of 6 months.
