Definitions

  • inventive concepts disclosed herein generally relate to implantable compression screws, and more particularly, but not by way of limitation, to a compression screw system with suture anchoring features and to methods of using same.
  • Implantable compression screws are typically used to manage bone fractures, for example, by implanting a compression screw into a fractured bone, such that the screw fixes, or compresses, fractured bone fragments against one another, thus allowing the bone to heal and re-grow.
  • an external plate may be compressed against the bone, typically by more than one compression screw, in order to reinforce the bone and allow it to heal.
  • Soft tissues such as tendons and ligaments
  • Soft tissues are generally attached to bone by small collagenous fibers. These fibers are strong, but permit the tendons and ligaments to be flexible. Some fractures, or other bone injuries, result in soft tissue being torn away or detached from the bone and requiring repair. Surgeons are often required to repair the detached soft tissue with one or more sutures which typically reattach the soft tissue to the bone via a suture anchor implanted into the bone.
  • suture anchors are usually implanted into a patient's bone through extensive surgical procedures or through arthroscopic surgical techniques.
  • some suture anchors may require a surgeon to tie a knot in the suture, or may be "knotless,” i.e., no knot is required to secure the soft tissue to the bone because the suture is retained by the suture anchor and the bone.
  • Existing compression screws are implanted into a patient's bone in a number of ways, which can generally be classified as those that require drilling of a hole in the bone, and those that can be implanted without drilling, such as by being pushed-in or screwed-in the bone, for example.
  • Some compression screws include threaded tips that are self-tapping, and some compression screws require that a hole or a channel be drilled or formed into the bone prior to implanting the compression screw into the bone.
  • variable-angle compression screws While some variable-angle compression screws have been developed in the prior art, such variable angle compression screws still have the above disadvantages (see for example U.S. patent application Serial No. 11/971 ,358, the entire disclosure of which is hereby expressly incorporated herein by reference).
  • suture anchors Another problem with currently existing compression screws is that they do not allow for sutures to be attached thereto, thus requiring that separate means for attaching sutures, such as suture anchors, be used to repair soft tissue injuries which often accompany a bone fracture.
  • suture anchors require separate insertion locations to be selected and additional insertion holes to be formed into already damaged bone, thereby resulting in prolonged surgical procedure times, increased procedure complexity and costs, and increased patient recovery time.
