BACKGROUND: Spinal navigation has made significant advances in the last two decades. After initial experiences with pedicle screws in the thoracic and lumbar spine, technological improvements have resulted in their increased application in the cervical spine. Instrumentation techniques like cervical pedicle screws, lateral mass screws in C1 and transarticular screws C1/C2 have become standard due to the application of image guidance. TECHNIQUE: Different navigation techniques can be distinguished based on the type of imaging...

BACKGROUND: Posterior decompression and stabilization plays significant roles in palliative surgery for metastatic spinal tumor. However, the indication for addition of posterior decompression have not been examined. The purpose of this study was to investigate a retrospective cohort of outcomes of metastatic spinal tumor treated with minimally invasive spine stabilization (MISt) with or without posterior decompression. METHODS: The subjects were 40 patients who underwent MISt using percutaneous pedicle screws for metastatic spinal tumor, including 20 patients treated with stabilization alone (group A) and 20 patients with added posterior decompression (group B)...

OBJECTIVE Patient-reported outcomes are commonly used to evaluate treatment efficacy. Inefficiencies in standard measurement tools often prove to be a barrier to data collection. The Patient-Reported Outcomes Measurement Information System (PROMIS) was developed to overcome these limitations. This tool implements computer-adaptive testing, which enables the assessment of physical function in fewer questions than those required for "static" metrics. In spine surgery patients, moderate to strong correlations with Oswestry Disability Index (ODI) and the 36-Item Short Form Survey (SF-36) scores have been reported for PROMIS...

Surgery for thoracic disc herniation and spinal stenosis is comparatively rare and often demanding. The goal is to achieve sufficient decompression without manipulating the spinal cord. Individual planning and various surgical techniques and approaches are required. This anatomical study examines the feasibility of a novel full-endoscopic uniportal technique with a transthoracic retropleural approach for decompression of the anterior thoracic spinal canal. Operations were performed on three fresh adult cadavers...

Surgical simulators are being increasingly used as an attractive alternative to clinical training in addition to conventional animal models and human specimens. Typically, surgical simulation technology is designed for the purpose of teaching technical surgical skills (so-called task trainers). Simulator training in surgery is therefore in general limited to the individual training of the surgeon and disregards the participation of the rest of the surgical team. The objective of the project Assessment and Training of Medical Experts based on Objective Standards (ATMEOS) is to develop an immersive simulated operating room environment that enables the training and assessment of multidisciplinary surgical teams under various conditions...

Adult scoliosis is a common condition. Symptoms could be very debilitating. Surgical management requires a clear assessment of the functional impact of scoliosis, the failure of conservative treatments and precise analysis of radiological investigations (full spine views, dynamic X-rays and MRI). Surgical techniques (anterior and posterior approaches, minimal invasive techniques, osteotomies, all spine instrumentation) must be tailored to each patient. The main goals of surgery are treatment of symptoms, correction of deformity in coronal and sagittal plane and achievement of a solid fusion...

Percutaneous pedicle screw fixation (PPSF) is a minimally invasive surgery (MIS) employed in the treatment of thoracolumbar burst fractures (TBF). However, hardware failure and loss of angular correction are common limitations caused by the poor support of the anterior column of the spine. Balloon Kyphoplasty (KP) is another MIS successfully used in the treatment of compression fractures by augmenting the injured vertebral body with cement. To overcome its limitations as a stand-alone procedure, it was suggested to augment PPSF with KP when treating TBF...

A possible risk factor for premature facet joint degeneration or adjacent segment degeneration after surgical treatment of spine fractures is facet joint violation (FV) during insertion of pedicle screws. Hence, the study aim was to determine risk factors for FV in the thoracic and lumbar spine following minimal-invasive screw insertion (MIS) or open instrumentation (OI). A retrospective analysis of all patients with spine fractures requiring posterior stabilization was performed. After allocation to the thoracic / lumbar group, FV was defined as an involvement due to the positioning of a pedicle screw and its severity as determined by computed tomography was assessed by using a customized scoring system...
