T1 mapping using MP2RAGE in degenerative cervical myelopathy: a longitudinal study.

Background And Purpose: Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord (SC) dysfunction. In routine clinical practice, SC changes are well depicted using conventional MRI, especially T2-weighted imaging. However, this modality usually fails to provide satisfactory clinico-radiological correlations.

Background: Metastatic epidural spinal cord compression (MESCC) and pathological vertebral compression fractures (pVCF) are the most serious debilitating morbidities of spine metastases (SpMs) causing devastating neurological damages. The respective impact of these two metastasis-spreading entities on survival and on neurological damage is debated.

Methods: A French prospective cohort study collected 279 consecutive patients presenting with SpMs between January 2017 and 2021.

Iatrogenic vertebral fracture in ankylosed spine during liver transplantation: a case report and biomechanical study using finite element method.

Purpose: The occurrence of an iatrogenic vertebral fracture during non-spinal digestive surgery is an exceptional event that has not been previously documented. Our study aims to explain the occurrence of this fracture from a biomechanical perspective, given its rarity. Using a finite element model of the spine, we will evaluate the strength required to induce a vertebral fracture through a hyperextension mechanism, considering the structure of the patient's spine, whether it is ossified or healthy.

The "Bevel drilling" for degenerative cervical myelopathy: A technical note with illustrative video.

Degenerative cervical myelopathy is a pathology frequently encounterd in the neurosurgical practice. Posterior ostophytes located at the posterior part of the vertebral endplate are frequently involved in the reduction of the cervical canal. We propose a description of the technique used in our department to drill this posterior part of the endplate safely with the help of modern instruments and microscope magnification.

Da Vinci Robotic Assistance for Anterolateral Lumbar Arthrodesis: Results of a French Multicentric Study.

Background: The da Vinci robot (DVR) is the most widely used robot in abdominal, urological, and gynecological surgery. Due to its minimally invasive approach, the DVR has demonstrated its effectiveness and improved safety in these different disciplines. The aim of our study was to report its use in an anterior approach of complex lumbar surgery.

Background: To report the feasibility and safety of C1 kyphoplasty using the Cirq® robotic assistance coupled to the AIRO® intraoperative computed tomography (iCT)-scan and BrainLab® navigation system.

Methods: A 47-year-old woman with C1 osteolytic lesion responsible of intractable left-sided suboccipital pain was admitted. She underwent a percutaneous kyphoplasty of left lateral mass of C1 using Cirq® robotic assistance.

Management of Spinal Metastasis by Minimally Invasive Surgical Techniques: Surgical Principles and Indications-A Literature Review.

Background: Spinal metastasis is becoming more frequent. This raises the topics of pain and neurological complications, which worsen the functional and survival prognosis of oncological population patients. Surgical treatment must be as complete as possible in order to decompress and stabilize without delaying the management of the oncological disease.

This phenomenon seems to be underreported, and its injury mechanism remains unclear.

Thoracolumbar vertebral fracture in unoperated idiopathic scoliosis.

Introduction: Traumatic fractures of the thoracolumbar spine are common. Their management considers the fracture type according to the various classifications in existence, as well as the patient's background and age. In some cases, the occurrence of a fracture on a spine with an unoperated scoliotic deformity can be observed.

Radiological analysis of minimally invasive treatment of type A thoracolumbar fractures based on a series of 135 fractures.

Introduction: Although the reduction of traumatic fractures of the thoracolumbar spine is of good quality during conventional so-called open procedures, the alternative minimally invasive approach also appears to confer good results. The aim of this study was to measure the radiological parameters before and after minimally invasive surgery, in order to assess the quality of the reduction of thoracolumbar compression fractures.

Materials And Methods: This retrospective, monocentric study included 112 patients with a mean age of 48.

Contribution of dynamic cervical MRI to surgical planning for degenerative cervical myelopathy: Revision rate and clinical outcomes at 5 years' postoperative.

Introduction: Cervical MRI is the gold standard for surgical planning of degenerative cervical myelopathy; however, the symptomatic postoperative recurrence rate is high in the medium and long terms (9.1% to 10.7%) and may bring into question the quality of the preoperative surgical plan.

Surgical management of large cerebellopontine angle meningiomas: long-term results of a less aggressive resection strategy.

Objective: Cerebellopontine angle (CPA) meningiomas present many surgical challenges depending on their volume, site of dural attachment, and connection to surrounding neurovascular structures. Assuming that systematic radical resection of large CPA meningiomas carries a high risk of permanent morbidity, the authors adopted an alternative strategy of optimal resection followed by radiosurgery or careful observation of the residual tumor and assessed the efficiency and safety of this approach to meningioma treatment management.

Methods: This single-center retrospective cohort study included 50 consecutive patients who underwent surgery for meningioma between January 2003 and February 2020.
