Missing portion of a tubular bone

Endoprosthesis of the hip joint

A material for connecting members for soft tissues and inner organs which consists of a copolymer of N-vinylpyrrolidone and alkyl esters of acrylic and/or methacrylic acid containing in the alkyl group 2 to 8 carbon atoms at the following proportions of the components, molar percent:

Material for connecting members for inner soft tissues and organs

Sutural material

According to the present invention there is provided a joining element for fixation of bone tissues, which is made essentially as an oblong solid provided with recesses, wherein are made fast inserts of a biologically compatible polymer, containing a physiologically active medical preparations.

Joining element for fixation of bone tissues

A device for uniting bone fragments comprises a rectilinear body and a contrivance for fixing it in the coapted bone fragments. The contrivance for fixing the body in the coapted bone fragments is formed by thrust members being the portions of the body located at the opposite ends thereof and having holes coaxial with the body; the holes being shaped as frustums of cones facing with their greater bases the ends of the body, and having annular grooves in the wall thereof, and cone-shaped inserts with annular ridges adapted to be introduced into the conical holes for wedging apart the body. The body has longitudinal through slots within the zones of the holes. The length of the device is less than the total length of the coapted bone fragments so as to be located fully within the bone tissues.

Device for uniting bone fragments

According to the present invention there is provided a joining element for fixing bone tissues, which is made essentially as an oblong solid provided with recesses, wherein are made fast inserts of a biologically compatible polymer, containing a physiologically active medical preparations.

This invention relates to medical technique and more particularly it relates to biodestructive materials used to manufacture elements for fixation of bone fragments. Said material contains a matrix of non-toxic polymer resolvable in the body consisting of hydrophilic and hydrophobic repeat units, and a reinforcing component of non-toxic fibres or threads resolvable in the body. The matrix polymer is preferably a copolymer of methyl methacrylate and N-vinyl pyrrolidone, and the reinforcing component is preferably fibre or threads of polyamide and oxycellulose. Said material can be used in medicine for fixation of bone fragments in fractures or injuries of bones.
