Zusammenfassung:A fastener including an elongated body having one or more ridges passing across its exterior surface intersecting root portions between them. Each ridge has a crest portion with edges bounded by distal and proximal slope portions extending inwardly from the crest edges to the root portions. A coating is disposed on the crest portion and at least part of the distal slope portion but not on at least part of the root portion. The coating has a selected coefficient of friction different from that of the exterior surface of the elongated body. The fastener further includes an element for engaging a driver to enable insertion of the elongated body into a tissue of the patient. The coating modifies the amount of force which must be applied to the driver to insert the fastener.
