Definitions

  • the invention relates to a cervical disc prosthesis suitable for use in cervical vertebral hernias in field of medicine.
  • the invention especially relates to a cervical disc prosthesis which comprises a movable blade and which provides a more stable structure by sticking into the bone thanks to this feature.
  • cervical hernias In cervical (neck) hernias (rupture), simple discectomy is the first surgical intervention method. As time passed by and the technology used in medicine improved, bone wedges suitable for the region extracted from the body were started to be used for the disc parts removed in cervical hernias. Later, synthetic structures (cage) started to be placed in the space of the removed disc. Today, with the improvement of the technology, cervical disc prostheses consisting of single or double movable parts are started to be placed in place of the removed disc.
  • cervical disc prosthesis surgery there is not an integration in the movable middle section.
  • the bottom and top surface sections of the prosthesis integrate with the bone, the neck movement of the patient are not restricted.
  • the disc length of the top and bottom segments in cervical disc prosthesis are not disrupted, quality of life of the patient increases.
  • the most important complication of cervical prosthesis surgery is the detachment of the cervical disc prosthesis from disc length after the surgery due to being movable and thus, damaging the anatomical structure of the bone in accordance with the applied prosthesis. Moreover, by harming the carotid artery, esophagus and trachea, which are the vital structures in said region, it constitutes life-threatening damages.
  • existing prostheses are placed inside the disc length after the cervical disc is removed, there is a possibtiity for them to detach from this length.
  • Some prostheses detach due to the inadequacy of prosthesis surfaces to hold onto the bone at the top and bottom when lowered to the disc length.
  • Some prostheses on the other hand, comprise big lugs on the prosthesis surfaces that will hold onto the bone at the top and bottom when lowered to the disc length. These lugs form a track from the top to the bottom inside the bone. As they form a track on the bone, it is highly possible for them to detach from said track.
  • Some prostheses comprise big, blunt or ragged protrusions on the middle section of the prosthesis surfaces that will hold onto the bone at the top and bottom when lowered to the disc length. These protrusions damage the bone structure while being placed in the prosthesis disc length and form tracks on the bone. This causes the prosthesis to detach from the disc length. In some cases, due to the damage to the bone and the formed tracks, the prosthesis causes the bone to crack from the middle line.
  • Some of the existing prostheses comprise some mechanisms which are stuck into the bone as additional protrusion on the surface of the prosthesis. As these mechanisms take a large space on the surface of the prosthesis, in order to fit them into the disc length, a part of the bone structure must be removed. This causes the disruption of existing anatomical structure and the disruption of cervical balance dynamic. In some existing prostheses, after the prosthesis is placed, the top and bottom surfaces are fixed to the surface of the bone with screws. These prostheses not only are hard to apply, but also require extra process. As there are extra foreign objects on the body when this prosthesis is applied, the risk of infection increases.
  • One of the patents related to the subject in the literature is the patent application No. CN1457750A.
  • the exterior surfaces of the cervical cage disclosed in said application have a ragged structure. While being placed between two bones, the cervical cage leaves a track on the bone as it moves inside. The tracks formed on the bone may later cause the prosthesis to detach when it is required to retract.
  • the top and bottom cage provide back and forth movement.
  • Another invention is disclosed in the patent application No. TR200804254B. Said application comprises a circular upper body and a lower body used in the neck section, which operate together and which provide turning of the neck. Moreover, it is a cervical disc prosthesis which comprises a connection end that connects said bodies to each other; and an at least one movement gap that is formed in the middle section of the upper body and the lower body.
  • the invention relates to a cervical disc prosthesis with movable blade which meets the requirements stated above, eliminates ail the disadvantages and brings forth some additional advantages.
  • the main object of the invention is to prevent the detachment of the prosthesis from the disc length thanks to the movable blade which is formed on the exterior surfaces and as impacted in the exterior surfaces in which the bottom and top surfaces of the cervical disc prostheses contact the bone.
  • An object of the invention is to prevent formation of tracks on the bone structures during the implantation of the prosthesis due to the impacted structure comprised by the movable blade on the surfaces.
  • Another object of the invention is to provide opening and closing of the movable blade, which is impacted thanks to the slot comprised by the exterior surfaces of the prosthesis, with a movement member.
  • the movable blade is stuck and fixed into the bone structure when it is opened.
  • its detachment from the disc length is prevented.
  • thanks to the folding feature thereof it can be removed and reinstalled when intended or required.
  • the prosthesis placed in the space created by the removal of the disc is not in the suitable location, it can be easily removed by closing into the slot in which said blade was previously impacted. Later, it can be re-installed into the same place optionally.
  • end plates of the top and bottom vertebra are not damaged.
  • Another object of the invention is to provide a stable structure thanks to sticking of the blade into the bone by being opened.
  • prosthesis does not move back and forth on the bone surface.
  • the neck movement of the patient is easily ensured.
  • the slot in which the blade was previously impacted is left empty. This situation ensures an easier fusion of the bone structure by moving towards said slot and more durable adhesion of the prosthesis surface to the bone.
  • a similar object of the invention is to provide the use of the prosthesis according to the invention in two length cervical hernias.
