INTRODUCTION: Adjacent level spondylodiscitis (ALS) after primary surgery for thoracic spondylodiscitis is a very rare condition. CASE REPORT: We report the case of a 76-year-old man with this pathology. A first posterior minimally invasive approach combined with anterior approach to the thoracic spine was safely performed for thoracic spondylodiscitis. More than a year later, exploration of recurrent symptoms with 18 FDG PET scan helped to diagnose ALS. Further surgery was performed...

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...

BACKGROUND: Surgeries performed for metastatic spinal tumor are mostly palliative and are controversial for patients with short life expectancy. We investigated whether palliative posterior spinal stabilization surgery with postoperative multidisciplinary therapy results in improvement of life prognosis and activities of daily living (ADL) in patients with metastatic spinal tumor. METHODS: The subjects were 55 patients who underwent palliative posterior-only instrumentation surgery for metastatic spinal tumor at our hospital between 2012 and 2015...

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...

BACKGROUND: The unilateral biportal endoscopic (UBE) technique is a minimally invasive procedure for spinal surgery, while open microscopic discectomy is the most common surgical treatment for ruptured or herniated discs of the lumbar spine. A new endoscopic technique that uses a UBE approach has been applied to conventional arthroscopic systems for the treatment of spinal disease. In this study, we aimed to compare and evaluate the perioperative parameters and clinical outcomes, including recovery from surgery, pain and life quality modification, patient's satisfaction, and complications, between UBE and open lumbar microdiscectomy (OLM) for single-level discectomy procedures...

OBJECTIVE Image guidance for spine surgery has been reported to improve the accuracy of pedicle screw placement and reduce revision rates and radiation exposure. Current navigation and robot-assisted techniques for percutaneous screws rely on bone-anchored trackers and Kirchner wires (K-wires). There is a paucity of published data regarding the placement of image-guided percutaneous screws without K-wires. A new skin-adhesive stereotactic patient tracker (SpineMask) eliminates both an invasive bone-anchored tracker and K-wires for pedicle screw placement...

Interspinous spacers used stand-alone preserve joint movement but provide little protection for diseased segments of the spine. Used as adjuncts with fusion, interspinous spacers offer rigid stability but may accelerate degeneration on adjacent levels. Our new device is intended to balance the stability and preserves motion provided by the implant. A new interspinous spacer was devised according to the results of topology optimization studies. Four finite element (FE) spine models were created that consisted of an intact spine without an implant, implantation of the novel, the device for intervertebral assisted motion (DIAM system), and the Dynesys system...

OBJECTIVE: The impact of obesity on spine surgery has been studied extensively, but just a few investigations have been focused on minimally invasive spinal fusion techniques and complication rates in normal-weight, preobese, or obese patients. Obesity was found to be a risk factor for intraoperative complications. Published data tend to favor minimal access surgery techniques (MAST) for obese patients. In a prospective study, we assessed the perioperative and postoperative complications of MAST in a large population of 187 patients...
