Impact of Various Weights in the Intraoperative Skull-Skeletal Traction on Correction of Adolescent Idiopathic Scoliosis.

Study Design: A retrospective study.

Objectives: Intraoperative skull-skeletal traction (ISST) facilitates the surgical scoliosis correction, but it is also associated with neurological risk. The objective of the present study was to investigate the impact of various traction weights on neurophysiological change and curve correction in surgery for adolescent idiopathic scoliosis (AIS).

Using tranexamic acid soaked absorbable gelatin sponge following complex posterior lumbar spine surgery: A randomized control trial.

Objectives: This paper aims to determine whether the use of Tranexemic Acid (TXA) - soaked absorbable gelatin sponge could more effectively reduce post-operative blood loss and blood transfusion requirements among low-risk adult patients undergoing lumbar spine surgery.

Methods: A total of 90 consecutive patients undergoing surgery for multilevel posterior lumbar degenerative procedures were prospectively randomized into one of three groups: - TXA Soaked Gelfoam group, absorbable gelatin sponge group or control group. Demographic distribution, total drain output, blood transfusion requirement, length of hospital stay, the number of readmissions, and postoperative complications were analyzed.

Does intraoperative cell salvage system effectively decrease the need for allogeneic transfusions in scoliotic patients undergoing posterior spinal fusion? A prospective randomized study.

Purpose: To determine the safety and efficacy of intraoperative cell salvage system in decreasing the need for allogeneic transfusions in a cohort of scoliosis patients undergoing primary posterior spinal fusion with segmental spinal instrumentation.

Methods: A total of 110 consecutive scoliosis patients undergoing posterior instrumented spinal fusion were randomized into two groups according to whether a cell saver machine for intraoperative blood salvage was used or not. Data included age, body mass index, perioperative hemoglobin levels, surgical time, levels fused, perioperative estimated blood loss, perioperative transfusions and incidence of transfusion-related complications.

Association Between rs11190870 Polymorphism Near LBX1 and Susceptibility to Adolescent Idiopathic Scoliosis in East Asian Population: A Genetic Meta-Analysis.

Study Design: Meta-analysis to collect all the relevant studies to date to further investigate whether or not the rs11190870 polymorphism is associated with susceptibility to adolescent idiopathic scoliosis (AIS) in East Asian population.

Objective: To investigate whether or not the rs11190870 polymorphism is associated with susceptibility to AIS in East Asian population.

Summary Of Background Data: To date, the single nucleotide polymorphism rs11190870 was identified as the most significant common variant in Japanese females.

Safety of surgical treatment for patients with scoliosis and surgically corrected congenital cardiac malformations: a comparison with patients with scoliosis and normal hearts.

Object: The safety of spinal fusion has been poorly studied in children with surgically corrected congenital cardiac malformations (CCMs). The objective of this study was to evaluate the safety of spinal fusion in patients with CCMs following cardiac surgery.

Methods: A retrospective study was conducted on 32 patients with scoliosis who received surgical treatment for their CCMs (CCM group).

Reliability of quantitative magnetic resonance imaging methods in the assessment of spinal canal stenosis and cord compression in cervical myelopathy.

Study Design: Prospective, blinded reliability study of quantitative magnetic resonance imaging (MRI) measures in patients with cervical myelopathy.

Objective: To assess the intra- and interobserver reliability of commonly used quantitative MRI measures such as transverse area (TA) of spinal cord, compression ratio (CR), maximum canal compromise (MCC), and maximum spinal cord compression (MSCC).

Summary Of Background Data: There is no consensus on an optimal quantitative MRI method(s) in assessing canal stenosis and cord compression.

Upper instrumented vertebral fractures in long lumbar fusions: what are the associated risk factors?

Study Design: A retrospective comparative study.

Objective: To investigate the risk factors associated with upper instrumented vertebral (UIV) fractures in adult lumbar deformity.

Summary Of Background Data: Long segment lumbar fusions may lead to junctional failures.

Comparison between subcutaneous closed-suction drainage and conventional closed-suction drainage in adolescent idiopathic scoliosis patients undergoing posterior instrumented spinal fusion: a randomized control trial.

Study Design: Prospective, randomized controlled clinical study.

Objective: To evaluate the efficacy of subcutaneous closed-suction drainage in reducing blood loss as compared with conventional closed-suction drainage in adolescent idiopathic scoliosis cases undergoing posterior instrumented spinal fusion.

Background: Subcutaneous closed-suction drainage is reported to be a reasonable alternative to intra-articular indwelling closed-suction drainage and to that of no usage of any drainage system in knee arthroplasty.

Accuracy and reliability of MRI quantitative measurements to assess spinal cord compression in cervical spondylotic myelopathy: a prospective study.

Study Type:  Reliability study Introduction:  Cervical spondylotic myelopathy (CSM) is the most common spinal cord disorder in persons more than 55 years old. Despite multiple neuroimaging approaches proposed to quantify the spinal cord compromise in CSM patients, magnetic resonance imaging (MRI) remains the procedure of choice by providing helpful information for clinical decision making, determining optimal subpopulations for treatment, and selecting the optimal treatment strategies. However, the validity, reliability, and accuracy of the MRI quantitative measurements have not yet been addressed.
