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...

BACKGROUND CONTEXT: The posterior pedicle screw-rod system, which is widely used to correct spinal deformities, achieves a good correction rate in the frontal and coronal planes but not in the axial plane. Direct vertebral derotation (DVD) was developed to correct axial plane deformities. However, the design of screw head and body connection, in terms of monoaxial, polyaxial, and uniplanar screw, may influence the efficiency of DVD. PURPOSE: This study compared the efficiency of a newly designed uniplanar screw to that of monoaxial and polyaxial screws in the DVD maneuver...

PURPOSE: Implant failure is a frequent complication in corrective surgery for early onset scoliosis, since considerable forces are acting on small and fragile vertebrae. Osseointegration showing biomechanical and histological improvement in bone-implant interface (BII) after dental implant placement has been well investigated. However, there are no studies regarding osseointegration in immature vertebral bone. The purpose was to evaluate the timecourse of biomechanical and histological changes at BII after pedicle screw placement using in vivo immature porcine model...

Management of spinal deformities in a patient with arthrogryposis can be challenging for spine surgeons. The literature about the accompaniment of scoliosis; the most common spine deformity reported in arthrogryposis, is still poor. Moreover, the development of cervical kyphosis and thoracic lordoscoliosis in a patient with arthrogryposis is much rare. This paper reports a 26-year-old medical doctor with arthrogryposis who had underwent thoracic lordoscoliosis surgery about ten years ago with T6-L1 internal rods and is now presented with cervical kyphosis and C3-C4 cord stenosis, which made him a candidate for cervical cord decompression surgery...

Droperidol is a D2 receptor antagonist currently used in Europe for preventing postoperative nausea and vomiting. It was used to perform neurolept anaesthesia in combination with fentanyl until a Food and Drug Administration (FDA) 'black box' warning restricted its use due to cardiovascular side effects in 2001. There is no literature regarding the effects of droperidol on transcranial motor evoked potentials (TcMEPs) elicited by electrical stimulation. Our aim was to report two cases of spine surgery in which TcMEPs were lost due to droperidol administration...

BACKGROUND: An ideal animal model has always been the key to research the pathogenesis and treatment of adolescent idiopathic scoliosis (AIS), while available methods have obvious disadvantages. The deficiency of melatonin has been proved relating to AIS. In this research, we intended to apply Luzindole, the melatonin antagonist, in bipedal rat model, for the block of combination of melatonin and its receptor, to inhibit the melatonin effect, and then to understand whether this method can effectively improve the scoliosis rate of bipedal rat model, and investigate the role of melatonin in scoliosis...

BACKGROUND CONTEXT: Schwab classification for adult degenerative scoliosis (ADS) concluded that health-related quality of life (HRQOL) was closely related to curve type and three sagittal modifiers. It was suggested that pelvic incidence minus lumbar lordosis value (PI-LL) should be corrected within -10°~+10°. However, recent studies also indicated that ideal clinical outcomes could also be achieved in patients without ideal PI-LL mentioned above. PURPOSE: This study evaluated the relation between the clinical outcomes and the pelvic incidence minus lumbar lordosis value (PI-LL) of Chinese patients with ADS who received long posterior internal fixation and fusion...

Lumbar degenerative scoliosis is a relatively common problem, and is being treated more frequently due to the confluence of an aging population and an increased capacity and willingness to manage difficult problems in older patients. Lumbar degenerative scoliosis is a complex pathology as it often involves the intersection of degenerative spinal stenosis and spinal deformity. While previous studies provide an indication that these patients may benefit from surgical treatment, the substantial variability in treatment underscores the opportunity for improvement...

OBJECTIVE Systematic multidisciplinary approaches to improving quality and safety in complex surgical care have shown promise. Complication rates from complex spine surgery range from 10% to 90% for all surgeries, and the overall mortality rate is 1%-4%. These rates suggest the need for improved perioperative complex spine surgery processes designed to minimize risk and improve quality. METHODS The Group Health Research Institute and Virginia Mason Medical Center implemented a systematic multidisciplinary protocol, the Seattle Spine Team Protocol, in 2010...

BACKGROUND: Chronic postsurgical pain (CPSP) affects half a million children annually in the United States, with dire socioeconomic consequences, including long-term disability into adulthood. The few studies of CPSP in children are limited by sample size, follow-up duration, non-homogeneity of surgical procedure and factors evaluated. METHODS: In a prospective study of 144 adolescents undergoing a single major surgery (spine fusion), we evaluated demographic, perioperative, surgical and psychosocial factors as predictors of a continuum of postsurgical pain: immediate, pain maintenance at 2-3 months (chronic pain/CP) and persistence of pain a year (persistent pain/PP) after surgery...
