BACKGROUND: Children undergoing posterior spinal fusion experience high blood loss often necessitating transfusion. An appropriately activated coagulation system provides hemostasis during surgery, but pathologic dysregulation can cause progressive bleeding and increased transfusions. Despite receiving antifibrinolytics for clot stabilization, many patients still require transfusions. AIMS: We sought to examine the association of dilutional coagulopathy with blood loss and blood transfusion in posterior spinal fusion for pediatric scoliosis patients...

Background: Three-column osteotomy is an effective means of correcting fixed sagittal plane deformities. Deformity correction surgeries may be associated with early postoperative neurological deficits often presenting as palsies involving the lumbar roots. The objective was to retrospectively assess a subset of our series of adult deformity correction surgeries and analyze neurological deficits and associated patient and surgical factors. Methods: Hospital records of 17 patients from a single center were examined...

BACKGROUND: Intraoperative blood loss during posterior spinal fusion for adolescent idiopathic scoliosis (AIS) has been reportedly associated with multiple factors. This study aims to investigate the effect of thoracic kyphosis on blood loss in AIS spinal fusion. METHODS: Patients with AIS who underwent posterior-only procedures for Lenke I and II type curves were identified. All included patients had intraoperative tranexamic acid. Difference in estimated blood loss per blood volume (EBL/BV) was identified between hypokyphotic curves (-), normal curves (N), and hyperkyphotic curves (+) classified based on Lenke sagittal modifier...

CASE: We utilized a novel staged approach for an adolescent with severe kyphoscoliosis; it involved 8 weeks of initial halo-gravity traction as well as implantation and expansion (every 2 weeks) of a magnetically controlled growing rod over 6 months, followed by spinal fusion. The patient was a 13-year-old girl with an untreated idiopathic deformity (thoracic scoliosis with a curve of 145° and kyphosis with a curve of 120°). No osteotomies other than inferior facetectomies were required at the final fusion, and the final scoliosis curve was 57°, a correction of 60...

The purpose of this study was to clarify the prevalence of scoliosis and determine risk factors for the development of scoliosis in young children with osteogenesis imperfecta (OI) who underwent intravenous pamidronate (PAM) therapy. Thirty-four young children with OI who had no scoliosis at the first PAM administration underwent cyclic PAM therapy alone. The medical records and radiographs of these patients were retrospectively reviewed. We examined the relationship between scoliosis (Cobb angle ≥ 10) and type of OI (Sillence classification: types I, III, and IV), physical mobility, Z-scores of bone mineral density in L2-4 of the lumbar spine (L2-4 BMD Z-scores), age of patients at first treatment with PAM, pelvic frontal tilt and leg-length discrepancy...

This review mainly focused on the etiology and the surgical strategy for adolescent idiopathic scoliosis (AIS) treatment. Genome-wide association study on the etiology of AIS using samples from more than 5 000 patients and 6 000 normal controls showed two genes: LBX1-AS1 on 10q24.32 and TNIK on 3q26.2 highly related to AIS initiation and progression. Regarding the conservative treatment of AIS, bracing is the only well-documented effective non-operative management in the early stage of AIS. For the patients with Cobb angle smaller than 80°, balancing spine, saving fusion level and restoring thoracic kyphosis are the basic objectives in surgical management...

BACKGROUND: Minimally invasive surgery (MIS) correction for adult spinal deformity (ASD) may reduce the need the need for postoperative skilled nursing facility (SNF) or inpatient rehabilitation (IR) placement following surgery. The likelihood of requiring placement in a facility rather than home disposition may be influenced by various factors. In addition, the associations between discharge location and outcomes and complication rates have not been elucidated in these patients. In this study, we aimed to define factors predicting disposition to an SNF/IR and to elucidate the rates of complications occurring in patients sent to home versus to a facility...

Pedicle subtraction osteotomy (PSO) is an effective technique to correct fixed sagittal malalignment. A variation of this technique, the "trans-discal" or "extended" PSO (Schwab grade IV osteotomy), involves extending the posterior wedge resection of the index vertebra to include the superior adjacent disc for radical discectomy. The posterior wedge may be resected in asymmetric fashion to correct concurrent global coronal malalignment.This video illustrates the technical nuances of an extended asymmetrical lumbar PSO for adult spinal deformity...
