Remodeling morphology of the subluxated osteotomy vertebra in closing-opening wedge osteotomy in ankylosing spondylitis: would the anterior bony beak blunt?

Introduction: To investigate the remodeling morphology of subluxated osteotomy vertebra in ankylosing spondylitis (AS) patients with thoracolumbar kyphosis after single-level closing-opening wedge osteotomy (COWO).

Materials And Methods: Standing lateral radiographs were taken to evaluate sagittal parameters including lumbar lordosis (LL), C7 sagittal vertical axis (SVA), global kyphosis (GK), sacral slope (SS), and pelvic tilt (PT). Radiographic parameters of the osteotomy vertebra included osteotomized vertebra angle (OVA), sagittal translation (ST), anterior height (AH), posterior height (PH), and middle height (MH) of the osteotomy vertebrae.

Long fusion to the pelvis with S2-alar-iliac screws can induce changes in pelvic incidence in adult spinal deformity patients: analysis of predictive factors in a retrospective cohort.

Purpose: To verify whether pelvic incidence (PI) would change in adult spinal deformity (ASD) patients who underwent long instrumentation using S2-alar-iliac (S2AI) screws and to identify factors associated with the change in PI.

Methods: We retrospectively reviewed all patients who underwent spinal surgery using S2AI screws between November 2014 and January 2017 at our institution. Patients aged 20 years or above with available radiographs were included.

Prediction of respiratory function in patients with severe scoliosis on the basis of the novel individualized spino-pelvic index.

Objective: Our study aimed to evaluate the pulmonary function of patients with severe scoliosis after correcting standing height with spino-pelvic index (SPI).

Methods: Inclusion criteria: (1) with a coronal Cobb angle of more than 90°; (2) diagnosed as congenital (CS) or idiopathic scoliosis (IS); (3) aged between ten and 20 years; (4) with pulmonary function test (PFT) at the primary consultation. Patients with previous surgical intervention, with angular kyphosis, and with neuromuscular disease were excluded.

Polymorphism of rs2767485 in Leptin Receptor Gene is Associated With the Occurrence of Adolescent Idiopathic Scoliosis.

Study Design: A genetic association study of leptin receptor (LEPR) gene with adolescent idiopathic scoliosis (AIS) in the Chinese Han population.

Objective: To determine whether LEPR gene polymorphisms are associated with the predisposition and/or disease severity of AIS.

Summary Of Background Data: Patients with AIS were reported to have lower body mass index (BMI), abnormal leptin bioavailability, and systemic lower bone mass, which implied that leptin/LEPR signaling pathway may be implicated in the etiology of AIS.

Pregnancy-related Acute Kidney Injury and a Review of the Literature in China.

Objective: To determine the incidence, causes and prognosis of pregnancy-related acute kidney injury (PR-AKI) in Chinese women.

Methods: From July 2004 to February 2013, 18,589 women of Han ethnicity who attended the Obstetrics and Nephrology Department of our tertiary hospital were investigated, and individuals meeting the PR-AKI criteria were included in the analysis. The WanFang, Chinese Science Journal, Chinese Knowledge, MEDLINE, EMBASE and Cochrane library databases were searched, and literature describing PR-AKI diagnoses with Chinese women as study subjects and a sample size of ≥5 were included.
