Implant for reconstruction of joints
A spacer member ( 1 ) is intended to be placed between the ends of the bones which are to be connected, one end of the spacer member being designed to form a joint surface against one of the bone ends ( 6,7 ). A joint-stabilizing connection ( 2,3 ) is arranged to connect the bones. The spacer member ( 1 ) is made of at least one tissue-compatible material.
1. Implant for reconstruction of joints, preferably of the hands and feet, comprising
at least one spacer member ( 1 ) adapted to be placed between the ends of the bones which are to be connected, one end of the spacer member being designed to form a joint surface against one of said bone ends ( 6 , 7 ),
a joint-stabilizing connection ( 2 , 3 ) adapted to connect said bones,
the spacer member ( 1 ) being made of at least one tissue-compatible material,
the joint-stabilizing connection ( 2 , 3 ) being adapted, upon use of the implant, to extend in the longitudinal direction across the joint and in over at least one side of the two bones ( 4 , 5 ) which are connected by the joint,
the material of the spacer member ( 1 ) being at least partly porous,
the spacer member ( 1 ) and the joint-stabilizing connection being made of degradable material,
the joint-stabilizing connection being made in one piece with the spacer member ( 1 ),
the degradable material being polyurethane urea;
the spacer member ( 1 ) and the joint-stabilizing connection being made entirely of woven fibrous material; and
the spacer member ( 1 ) and the joint-stabilizing connection comprising at least two branches that meet at a dihedral angle.
