Definitions

  • the present invention relates to the technical sector of methods and surgical means for surgical grafting of a graft constituted by a graft constituted by bone-tendon-bone in a in a dislocated and/or subluxated joint, in particular when the joint is a scapholunate joint of a patient.
  • graft constituted by bone-tendon-bone are taken to mean a graft, in a single body, which comprises: a portion of a first joint bone; a portion of the capsular-ligament zone of the joint: and a portion of a second joint bone.
  • a second solution can include collecting a graft from another healthy joint and positioning the graft in a grafting site in the dislocated and/or subluxated joint by drawing the graft using a guide wire into an appropriate channel in the patient up to a grafting site.
  • the aim of the present invention consists in reducing and/or obviating the above-cited drawbacks relative to the surgical means and methods for surgical grafting of the graft in a dislocated and/or subluxated joint.
  • the present invention has the aim of guaranteeing the correct positioning of the graft in the grafting site.
  • a further aim of the present invention is to position, with high precision, the graft in a dislocated and/or subluxated joint, in particular if scapholunate, with simple surgical methods, by making available a surgical device for surgical grafting of a graft constituted by bone-tendon-bone in a dislocated and/or subluxated joint which is constructionally simple and economical as well as reliable in use.
  • the aims and objectives are obviated with a surgical device for surgical grafting of a graft constituted by a graft constituted by bone-tendon-bone in a in a dislocated and/or subluxated joint according to claim 1 and with a surgical method according to claim 11.
  • the present invention enables positioning the graft in the grafting site with high precision, by carrying out a surgical method that is simple and reliable.
  • the applicant has experimentally found that when the graft is pushed, for example by means of a cylinder-piston system, into the grafting site, the same graft positioning accuracy that is obtained according to the invention is not obtained. This is probably due to the fact that by pushing the graft the ligament part thereof tends to be crushed. Consequently the portion of bone of the graft that is proximal to the access point tends to be incorrectly located.
  • the device of the invention is simple, easy to realise and therefore relatively economical. It follows that the costs correlated to the stabilisation of a dislocated joint will be significantly reduced with respect to the prior art.
  • the surgical device of the invention enables actuating the claimed surgical method. Obviously this method can comprise each step of use of the surgical device.
