To develop a deep learning-based cascaded HRNet model, in order to automatically measure X-ray imaging parameters of lumbar sagittal curvature and to evaluate its prediction performance. ⋯ The cascaded HRNet model based on deep learning algorithm could accurately identify the sagittal curvature-related landmarks on lateral lumbar DR images and automatically measure the relevant parameters, which is of great significance in clinical application.

To develop a deep neural network for the detection of inflammatory spine in short tau inversion recovery (STIR) sequence of magnetic resonance imaging (MRI) on patients with axial spondyloarthritis (axSpA). ⋯ The developed deep neural network showed similar sensitivity and specificity to a radiologist with four years of experience. The results indicated that the network can provide a reliable and straightforward way of interpreting spinal MRI. The use of this deep neural network has the potential to expand the use of spinal MRI in managing axSpA.

One of the major advantages of a minimally invasive microdiscectomy is that when CSF leak occurs, there is minimal anatomic dead space for ongoing leakage following removal of the tubular retractor. However, there are no published reports that address the safety and long-term outcomes of same-day discharge for CSF leak after tubular microdiscectomy. ⋯ Patients with CSF leak during minimally invasive tubular microdiscectomy can be safely discharged home the same day.

Vertebral Body Tethering (VBT), an alternative treatment for adolescent idiopathic scoliosis, shows satisfactory post-operative results. However, the biomechanical quantities and consequences after VBT surgery remain largely unknown. Therefore, the aim of this study is to analyze the spinal biomechanics during different motions using a multibody simulation approach. ⋯ The biomechanical data provide a first impression of the forces that occur along the spine during various physiological movements and are consistent with published clinical data. Forces are not evenly distributed along the spine, with higher lumbar forces. The tether forces reach values during lateral bending that can potentially destroy the tether´s integrity and thus may explain the common post-operative complication, namely tether breakage. The results of the model can therefore have an impact on future directions for improved surgical VBT treatment.

SH is considered to be the most common benign tumor within the human spine. 1-2% of SH get symptomatic with back pain in most cases. Less often, ingrowth of vessels into the spinal canal is seen. In these cases, more invasive surgical treatment is required. Recurrence of SH following surgical treatment is a very rare condition. ⋯ Thus, radical excision, sufficient stabilization and fusion is considered to be an adequate treatment concept for recurrent SH.
