Asymmetric Posterior Thoracolumbar Fixation following a Posterolateral Transpedicular Approach for Unilateral Vertebral Disease
The present study aimed to evaluate the clinical outcomes of patients who underwent asymmetrical posterior screw fixation for the treatment of unilateral posterior vertebral pathological entities. The study included 21 patients with a spinal tumor who underwent asymmetrical posterior spinal fusion surgery between April 2009 and March 2012. The American Spinal Injury Association (ASIA) motor sco...
متن کاملClinical Results of Percutaneous Fixation of Pelvic and Acetabular Fractures: A Minimally Invasive Internal Fixation Technique
Background: The pelvic ring fractures (PRF) and acetabular fractures (AF) are among the major orthopedic injuriesassociated with high rates of morbidity and mortality. Open surgical stabilization is the standard treatment for themajority of these complications. Percutaneous minimally invasive surgical stabilization of the fractures has become anaccepted treatment method for th...
متن کاملAsymmetric auxin response precedes asymmetric growth and differentiation of asymmetric leaf1 and asymmetric leaf2 Arabidopsis leaves.
We have analyzed the development of leaf shape and vascular pattern in leaves mutant for ASYMMETRIC LEAVES1 (AS1) or AS2 and compared the timing of developmental landmarks to cellular response to auxin, as measured by expression of the DR5:beta-glucuronidase (GUS) transgene and to cell division, as measured by expression of the cycB1:GUS transgene. We found that the earliest visible defect in b...
متن کاملSpinopelvic fixation.
Fusion to the sacrum presents as a complex and difficult technical procedure with outcomes which have been up until recently, relatively poor, with high pseudoarthrosis rates and associated with the development of so called flat back deformity or loss of lumbar lordosis. Previous reports from the morbidity committee of The Scoliosis Research Society in the late 1970’s indicated that this did no...
متن کاملFormaldehyde fixation.
The use of formaldehyde as a biological reagent occurred rather late in the history of histological methodology. The reason for this lay not in any lack of astuteness on the part of pathologists and histologists, but rather with the late development of formaldehyde manufacture by the chemical industry. While formaldehyde was discovered by Butlerov in 1859, practical aspects of the manufacture o...
