Abstract
The invention relates to an implant (10) to sheath and/or reinforce bone and/or to anchor bone screws. The implant (10) takes the shape of a dowel which is capable of spreading and/or swelling and/or interlocking in bone in some other way. The implant (10) preferably presents ring-like bulges (16) on its outer surface and an internal screw thread (20) on its inner surface to screw in bone screws. Implant (10) improves the tensile strength when anchoring bone screws (Figure 1).
Claims35
An implant to support or reinforce bone or to anchor bone screws, artificial implants or implant compounds in a bone, said implant consisting of a body of absorbable, biocompatible material having a hollow cylindrical configuration having a closed end such that said implant is adapted to be fully insertable into the bone and means for spreading out or swelling the implant after being inserted in the bone thus finding a firm support in the surrounding bone.
An implant to support or reinforce bone or to anchor bone screws, artificial implants or implant compounds in a bone, said implant consisting of a body of absorbable, biocompatible material, said implant having a generally cylindrical configuration being fully insertable into the bone and comprising a double-walled stocking cage in which spheres 500-5000 .mu.m in size are held thus forming a lumen into which screw means can be screwed in or a cylinder or wedge can be inserted for spreading out the implant after being inserted in the bone.
