Clinical 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...

Spinopelvic 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...

Formaldehyde 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...

Nitrogen Fixation

Plant growth is directly dependent upon an adequate supply of fixed nitrogen. Water and fixed nitrogen are the most common limiting factors for plant growth.There is an abundance of nitrogen in the atmosphere, but it is in the form of the relatively inert gas, N2, and this must be converted chemically or biologically into a more active form before plants can utilize it. Chemical fixation most c...
