    Abstract: A method for treating scoliosis in a patient is disclosed. The method comprises identifying a spinal column having a lateral convex curve; providing a first anchor, a second anchor, and a tether; securing the first anchor to a posterior region of a first vertebra; securing the second anchor to a posterior region of a second vertebra; securing a first tether end at a first tether connection location; and securing a second tether end at a second tether connection location. A scoliosis treatment system comprises anchors, each having a tether connection location positioned at a first location offset in a first lateral direction from a midsagittal plane of the first or second vertebra, and the anchors do not include any tether connection locations offset in in a second lateral direction, opposite the first lateral direction, from the midsagittal plane of the first vertebra or second vertebra.

    Abstract: A novel method is disclosed to make cellulose filaments (CF) from wood or other plant fibers with lower energy consumption. The method consists of multi-stage, high consistency refining, followed by low consistency refining or by low consistency, non-refining mechanical treatment, of wood or other plant fibers. The total specific refining energy for the multi-stage, high consistency refining is preferably 2, 000 - 18,000 kWh/t, and more preferably 2,000 - 12,000 kWh/t. The CF produced can be used as a superior reinforcement additive in the production of paper, tissue or paperboard and in the production of plastic composites. It can also be used as a viscosity or rheology modifier in food products, coatings or drilling muds. The CF produced can also be used to make strong films for application in packaging and in composites.
