Abstract: A retrograde intramedullary nail for insertion in the medullary canal of a femur includes a body that is elongate and defines a leading end and a trailing end spaced from each other at a length sufficient to extend from an intercondylar region at least to a subtrochanteric region of the femur. The body further defines a leading portion that extends to the leading end. The leading portion defines at least one locking hole configured to receive a fixation member. The at least one locking hole defines a central hole axis that is oriented to extend through the neck and head of the femur.

Abstract: A method for the treatment of textiles surfaces has the steps:(i) a solids treatment material including a swollen hydrogel containing aqueous treatment fluid is applied to a surface,(ii) force is then applied to release the treatment fluids from the hydrogel,(iii) the textile is allowed to dry and(iv) visible residues are removed from the surface.The hydrogel is a hydrophilic homopolymer or copolymer of acrylic or methacrylic acid or salt/ester thereof; a homopolymer or copolymer of acrylonitrile; a cellulose ether, carboxylated cellulose derivative polyalkylene oxide or polyurethane optionally cross-linked with polysaccharide.The treatment fluid is for cleansing, insect-proofing, fragrancing or antibacterial/antifungal purposes.
