Definitions

  • the invention relates to fixation by screws in bones and in particular to adaptations making it possible to optimize this fixation.
  • the fixing device comprising such screws has several drawbacks, among these:
  • a first screw provided at its proximal end with a head for compressing the bone by a straight stop
  • a second screw provided at its distal end with a bone thread having a first helix pitch and at its proximal end with a bone thread having a helix with a pitch smaller than the first pitch propeller.
  • This device is intended for fixation without a bone graft plate in the shoulder for the treatment of pathologies linked to shoulder instability.
  • This device is more particularly intended for fixing the bone graft in the context of a Lartajet procedure.
  • the screw with head is generally placed first, in particular for the reasons mentioned above. In addition, it is usually the screw located in the lowest position that is installed first.
  • At least one of the screws comprises a cannula, that is to say that the screw is formed with a longitudinal through hole,
  • the screw with head comprises:
  • At least one of the screws comprises a conical proximal threaded portion.
  • the two screws comprise a conical proximal threaded portion.
  • the taper of the proximal portion of the two screws has a half angle of about 10 degrees.
  • the proximal part of at least one screw has a smooth portion.
  • the smooth portion is preformed on the screw with head between the head and the threaded proximal portion. This characteristic facilitates the manufacture of the screw by machining.
  • the device comprises the following two screws:
  • a cannula that is to say that the screw is formed with a longitudinal through hole with a diameter between 1 and 2 millimeters
  • a distal threaded portion (at a distance from the head) threaded according to a first pitch and with an outside diameter of between 3 and 5 millimeters;
  • the threads of the distal portions of the screws are double and the threads of the proximal portions are simple.
  • the two screws have a smooth central part separating the proximal portion from the distal portion.
  • the length of the distal threaded portion forms between 46 and 56 percent of the total length of the headless screw and forms between 48 and 58 percent of the total length of the headless screw.
  • the length of the proximal threaded portion is between 5 and 9 millimeters.
  • This length is defined so that the proximal threaded portion is engaged only and only in the graft and in no case in the host bone, this to allow compression.
  • the invention also relates to a fixing kit formed from the device described above, namely that the two screws of different designs are packaged in the same package.
  • the device is remarkable in that it comprises two screws of different designs which are packaged in the same package for the purpose of creating a ready-to-use fixing kit.
  • the kit consists of two screws with a length difference between 0.5 and 5.5 millimeters.
  • kits are delivered non-sterile in a packaging suitable for sterilization by the care establishment.
  • kits are delivered sterile in a packaging suitable for sterilization by gamma ray or x-ray and suitable for aseptic transfer of the device.
  • the fixing kit contains screws which have been selected and / or sized specifically for a patient according to a preoperative planning established on the basis of the patient's preoperative imagery.
  • the invention also relates to a method of fixing a bone graft on a shoulder bone remarkable in that it uses two screws and only two adopting the characteristics described above taken together or not. [74] This process thus applies to a so-called "Latarjet" fixation procedure.
  • the process comprises, before the selection and use of the screws, a preoperative planning comprising the following operations:
  • the preoperative planning method comprises, between the identification and planning operation, an operation for measuring at least one characteristic characteristic of the patient's joint.
  • Figure 1 is an exterior side view of an embodiment of a first of the two screws of the device of the invention
  • Figure 2 is a side view in section of the screw of Figure 1;
  • Figure 3 is an external side view of an embodiment of the second of the two screws of the device of the invention.
  • Figure 4 is a side view in section of the screw of Figure 3;
  • Figure 5 is a sectional view of an assembly of a bone graft to another bone.
  • Figure 6 is a diagram of the main phases of the process leading to the creation of a kit and / or screws according to the invention specific to a patient
  • One embodiment of the device of the invention consists of the two screws shown.
  • the first screw 100 in FIGS. 1 and 2 comprises a head 110 and a rod 120.
  • the head 110 includes an imprint 111 to cooperate with a fitting tool (not shown) allowing the insertion of the screw into the bone.
  • This first screw is preformed with a cannula 130.
  • Rod 120 breaks down into several portions:
  • the second screw 200 of Figures 3 and 4 is formed of a solid headless body which includes
  • the device is used for fixing the bone graft G to a host bone O.
  • the screws are dimensioned so that:
  • the distal threaded portions 124 and 230 only cooperate with the host bone O.
  • the length of the screws 100 and 200 is defined so that the distal threaded portions 124 and 230 of the screws pass through the cortical wall, of the host bone O, opposite the bone graft G.
  • the preoperative imaging of the patient to be operated on is acquired in various ways. For example, x-rays and / or ultrasounds and / or CT images and / or MRI of the shoulder are used.
  • a modeling and identification phase 320 On the basis of the preoperative imaging of the patient to be operated, during a modeling and identification phase 320, at least one segmentation and processing algorithm makes it possible to model the patient's joint, to identify at least one structure anatomical.
  • This phase can include the measurement of at least one characteristic characteristic of the patient's joint.
  • the surgeon performs preoperative planning using a computer interface making it possible to view the modeling of the joint and to carry out at least one of the following operations: size the graft, position the graft on the host bone and position and select the screws constituting the fixing device according to the invention.
  • This method may also include the constitution, manufacture and making available for surgical intervention of a patient-specific fixation kit produced on the basis of the data previously collected and, in particular, the output data from the planning.
