Generalized joint hypermobility (GJH) is a risk factor for developing adolescent idiopathic scoliosis (AIS); however, it is not known whether joint hypermobility influences the risk of progression to surgery. Beighton joint hypermobility scores were assessed in 570 female AIS patients. Multivariate analysis was carried out to determine whether Beighton hypermobility scores were predictors of surgical intervention. In this female AIS cohort, 24.7% (141/570) had GJH (Beighton score ≥4). Multivariate analysis showed that GJH did not influence the risk of surgery, although having no joint hypermobility (Beighton score=0) increased risk (odds ratio: 1...

t Superior Mesenteric Artery (SMA) syndrome is an uncommon condition caused by mechanical obstruction of the distal third of the duodenum between the superior mesenteric artery and the abdominal aorta. SMA syndrome is associated with both operative and non-operative corrections of scoliosis, as well as anorexia nervosa, severe weight loss, tumors, burns, and other traumas.[1-4] We report an unusual case of SMA syndrome following corrective surgery for scoliosis in which post-operative gastric distension caused duodenal compression that subsequently resolved with gastric decompression, as opposed to the conventional, reverse series of events in which SMA syndrome causes the gastric dilatation...

Until today the role of spinal instrumentation in the presence of a wound infection has been widely discussed and recently many authors leave the hardware in place with appropriate antibiotic therapy. This is a case of a 65-year-old woman suffering from degenerative scoliosis and osteoporotic multiple vertebral collapses treated with posterior dorsolumbar stabilisation with screws and rods. Four months later, skin necrosis and infection appeared in the cranial wound with exposure of the rods. A surgical procedure of debridement of the infected tissue and package with a myocutaneous trapezius muscle flap was performed...

BACKGROUND: Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) surveys are used to assess the quality of the patient experience following an inpatient stay. HCAHPS scores are used to determine reimbursement for hospital systems and incentivize spine surgeons nationwide. There are conflicting data detailing whether early readmission or other post-discharge complications are associated with patient responses on the HCAHPS survey. Currently, the association between post-discharge ED visits and HCAHPS scores following lumbar spine surgery is unknown...
