Abstract: The invention provides a surgical implant in the form of a stud for anchoring in a hole formed in bone. The stud has an elongated cylindrical body which is tubular and which has a head at one end and a passage along its interior. A pin is insertable into the passage from the end having the head to expand the body transversely to anchor it in the hole. The body and pin are of biocompatible material and the body contains carbon fibres embedded in and extending longitudinally along its interior.The invention provides also a surgical implant kit including the stud, and a method of surgery employing the stud and kit.

Abstract: A surgical element (1), such as a suture or a replacement for a ligament, comprises a core (2) consisting of a multiplicity of flexible filaments, such as fine carbon fibres, and partial sheathing (3) formed of standard implantable grade polymer, such as a polyester, in at least two groups (3X, 3Y) totalling less in width than the circumference of the core and interwoven in contra-rotation so that areas (4) of the core are exposed at frequent intervals, to encourage penetration and ingrowth of fresh tissue between the core filaments.

Abstract: A set of surgical instruments is provided, for threading a tow or skein of carbon fibres through a passage in bone. The set includes an elongated adaptor having a passage along its length for insertion into a passage in bone, a fish wire having a leading end provided with a hooked connector, and an extraction member with a hole therethrough the extraction member being insertable along the adaptor and through the hole in the extraction member in non-return fashion.
