OBJECTIVE To evaluate the radiographic outcomes of short-segment posterior instrumentation plus vertebroplasty using injectable calcium sulfate cement (CSC) for thoracolumbar compression fractures. MATERIALS AND METHODS Twenty-eight patients with a single-level thoracolumbar compression fracture, who underwent short-segment pedicle screw fixation and CSC vertebroplasty, were included in the s...

Herein we demonstrate how nanojunctions between lysosomes and sarcoplasmic reticulum (L-SR junctions) serve to couple lysosomal activation to regenerative, ryanodine receptor-mediated cellular Ca (2+) waves. In pulmonary artery smooth muscle cells (PASMCs) it has been proposed that nicotinic acid adenine dinucleotide phosphate (NAADP) triggers increases in cytoplasmic Ca (2+) via L-SR junctions...

OBJECTIVE Surgical treatment of Scheuermann's kyphosis (SK) remains a subject under discussion. In view of the controversy over the best form of surgical tr otomy. METHODS This was a descriptive case-control study with cross-sectional analysis. Twenty-eight patients, split into two groups conducted at different times, were evaluated. RESULTS The first group comprised patients treated using ...

Cervical anterior fusion is useful for the treatment of patients with cervical disease, but carries the risk of postoperative worsening of the cervical spine alignment and kyphosis. Preoperative prediction of the risk for kyphosis could help to avoid such postoperative complications. We attempted to predict the postoperative development of kyphosis in 59 patients scheduled for cervical anterior...

Objective. To identify the mechanism of deformity compensation in patients with post-traumatic kyphosis thoracolumbar junction, based on analysis X-ray results surgical treatment. Material and Methods. The study included data obtained from medical records 69 (47 women, 22 men) operated for painful at levels T12, L1 L2 vertebra. Patients underwent staged interventions a single session. Demograph...

OBJECTIVE To evaluate the results and complications of a series of patients who underwent three-column osteotomy using the posterior approach for correction of complex cases of rigid dorsal kyphotic deformity. METHODS Review of clinical records and images of 15 consecutive cases of pedicle subtraction osteotomies, bone-disk-bone osteotomies, or vertebral column resection, recording the etiolo...

STUDY DESIGN A retrospective radiographic study. PURPOSE To verify the correlation of sagittal and coronal plane changes after selective thoracic fusion in main thoracic (MT) adolescent idiopathic scoliosis (AIS). OVERVIEW OF LITERATURE Sagittal plane deformity is known to be essential in the evolution of scoliosis. METHODS Twenty-eight MT AIS patients treated by anterior selective thorac...
