Spinal anaesthesia is the most preffered anesthesia technique for total hip replacement, and its complications range from low entity (insignificant) to life threatening. The incidence of neurologic complications after neuraxial anaesthesia is not perfectly clear, although there are several described cases of spinal cord ischaemia. We present a case of unilateral T8-T11 spinal cord ischaemia following L2-L3 spinal anaesthesia for total hip replacement. Magnetic resonance imaging showed a hyperintense T8-T11 signal alteration on the leftside of paramedian spinal cord...

Introduction Because of recent increases in life expectancy, lumbar spinal stenosis (LSS) has become one of the most common degenerative changes in the spine. In patients not responding to conservative therapy, microsurgical decompression is the gold standard of operative treatment for degenerative LSS. The goal of the current study is to evaluate quality of life after microsurgical decompression for LSS, using data from the DWG Register (previously Spine Tango). Methods 36 patients were included in this single-center, prospective, observational study from January 2013 to June 2014...

Superior mesenteric artery (SMA) syndrome is a rare and potentially life-threatening complication of scoliosis surgery. The anatomical relationship of the duodenum and the superior mesenteric artery, the correction of angular deformity of the spine, and the normal adolescent growth spurt all contribute to the condition. We report the case of a 14-year-old boy who had a history of idiopathic scoliosis and presented with bilious vomiting that had persisted for 7 days after posterior T9-L4 fusion with instrumentation...
