Definitions

  • This invention is related to an external fixator in type of removable ball-socket articulated dynamic axial fixator used in treatments of fractured, deformed and shortness of long bones in the branches of Orthopaedics and traumatology of the field of medicine.
  • fixators of this type generally there are clamp parts which would hold both epiphysis separately, two articulation pieces adapted to clamps which provide redressing and adaptation of fracture, body illustrating the length of device and elongation rate thereof, distraction units ensuring extension and shortening.
  • distraction units achieve extension and shortening actions in the body as an unit annexed to body, and in the manufacture of this unit certain metal alloys being used with higher resistance and higher density but having less perviousness against X-rays, renders more difficult to fix the articulation by X-ray film.
  • excessive use of X-ray device is required to be able to do articulation fixation, and thus, both patient and doctor are being exposed to X rays more. Anyhow, the risk of fractured reposition loss is still higher due to insufficient articulation fixation. In addition thereto, super-position event is more frequently encountered in X-ray films.
  • Controlled dynamization could not be achieved due to device length could be changed by the rate cf force applied to distraction unit, and the risk of progression in shortness is increased consequently.
  • Usage cf devices in sizes more than one is necessary due to amount of distraction-ccmpressicn is limited. Weights of annexed devices and additional unit lead to loosening of nails during usage.
  • Articulation angle in existing fixators is maximum 22° and fixator is not sufficiently functional in fractured repositioning due to insufficiency of articulation angle.
  • purpose of this invention is to provide the fixator which would be used in treatments of fractured, deformed and shortness cf long bones at orthopaedics and traumatology being effective to fix the bone in a straight and stable manner until the completion of welding, and being capable of doing angularity and controlled dynamization, if needed, further its being functional as much as possible, having enough spaciousness for articulation movement and high modularity, stable, would not cause any reposition loss during application and within time; light, hygienic, pervious for X-rays in sufficient degree, capable fcr easy application, smoothly acceptable by patient and easily usable.
  • Fixator which is developed for attaining the objectives of this invention is shown in enclosed illustrations which reflect following c-tlooks;
  • Figure 1 Articulation fixation by using fixator on fractured bond.
  • Figure 2- Complete section of polyplanar clamped fixator.
  • FIG. 1 Figure 3- Complete section of monoplanar clamped fixator.
  • Figure 4- A view from a section of polyplanar clamp and articulation globe.
  • Figure 5- A view from a section monoplanar clamp and of clamp cover.
  • Figure 6- A view of removable articulation from a section.
  • Figure 8- A view of sliding clamp cover.
  • Figure 1 is the outlook of fixator in the position where polyplanar clamps have been fixed on bone through its special nails ( Figure 4).
  • fixator body (10) is telescopic, and works also by moving within extension belt (5). It is possible to use the body in large, middle and small sizes by selecting extension bolts in different longitudes.
  • Polyplanar clamp as is seen in Figures 2 and 4, is composed of two bolts (3), polyplanar clamp body (14), polyplanar clamp bottom cover (16), polyplanar clamp intermediary part (17) and polyplanar clamp upper cover (18), and is allowed to place nails in different plans and various combinations.
  • Fixator with inarticulated polyplanar clamp could be used in bones having a broad clinging surface (like metaphase), angularity of fractured and translation thereof could also be corrected through this clamp.
  • Monoplanar clamp as seen in Figures 2, 3 and 5, containing Monoplanar Clamp cover (1), Monoplanar clamp body (2) and 2 bolts (3) ensures the placement of nail in single plan, and could be used articulated or inarticulated manner according to requirements .
  • Figure 6 illustrates removable articulation.
  • clamp When needed, by loosening bolt on the clamp (3) space between clamp and tightening nut is broadened, and by turning eccentric pin (15) tightening cleat (11) is loosened and the globe (15, is become idled.
  • clamp could be given such angularity around a circle of 360° to a direction up to 30° from the center, so the angle of articulation is being increased and therefore device becomes more functional.
  • firstly tightening nut (12) is tightened for taking in the slack of articulation. Thereafter, eccentric pin (15) is tightened with "L-alian" wrench by maximum force.
  • clamp is made to be slided en the body of globe (13) until taking in the slack of articulation, and thus clamp body is leaned against tightening nut.
  • load is being transferred directly to the body and articulation could be removed or insufficiency position of articulation in angular fixation could be eliminated.
  • Through taking in the slack of articulation by tightening nut and reducing of height of eccentric pin (15) down to maximum 0.5 mm load arm is shortened, more tightening of globe is ensured, and stability is increased by sliding of eccentric in the course of time with a counter-screw applied to eccentric. Distraction- compression share has also been increased by removal of articulation.
  • Figure 2 is an outlook of distraction unit.
  • Distraction unit consisting of extension bolt (5), pressing spring '6), extension nut (7), ball (8), segment (9) and derotation pin (19) is placed within body. Therefore, annexed unit which was using for the same purpose has been removed, and in this way, perviousness cf device for X-rays is increased and radioscopy process becomes easier. At the same time, the risk of loosening in nails is also reduced along with decrease of super-position risk and the weight of device. If extension nut (7) is turned clockwise one tour, then the system is being extended 1.2 mm.
  • FIG 8 is an outlook of sliding clamp cover.
  • Monoplanar clamp cover (1) is slided towards outside by loosening external bolt (3) fcr smooth application of nail to the bone. After fractured reduction is achieved, external screw is tightened. After internal nail is placed into the bone, cover (1) is locked by being slided. This practice provides easiness in technical usage. In Figure 1, the locked position of sliding clamp cover and the area of movement of cover with the help cf bolt hole design could be seen.
  • Invention could reliably be used in long bones of extremities.
  • suitable fixator is selected as to the kind, location and length of bone. If articulated fixator is preferred, articulation in flat bones is hold firstly straight and closed, distraction-compression share is adjusted. Long bone is rather taken to traction. Nails at both farthest ends of fixator will be placed intc bone at 90° under sterile conditions. Thus, fractured re-position in front- rear plan is being ensured.
  • nail is placed at the same plan with first nail and parallel thereto into the hole nearest fractured or farthest hole from previous nail.
  • central line of bone is not balanced, fractured bone is pulled downward or upward, and central line is so matched. Same process is applied to opposite side and fractured ends are being reposed in lateral plan. When necessary, third nails are placed into center part in the same plan and parallel to others. Newness in clamp cover is ensured to ease such application.
  • fractured state is controlled by radioscopy or X-ray. If any angularity is observed, then articulation is opened and correction is made. Distraction-compression rate is adjusted and fixator is locked.

Abstract

Le fixateur axial dynamique stable de l'invention est un fixateur externe à rotule sphérique, monoarticulé, qui peut être retiré pour la stabilité et s'utilise en chirurgie orthopédique ou traumatologique. Le fixateur a été conçu pour une technique d'opération nouvelle et singulière qui augmente la stabilité tout en réduisant au minimum la nécessité de recourir aux rayons X. Les avantages supplémentaires se traduisent par une réduction au minimum de la superposition du fixateur sur l'image aux rayons X, par un risque minimal de perte de la broche grâce à son poids réduit, et par la réduction de la durée d'hospitalisation. Pour augmenter la stabilité de l'articulation, le 'contact de la pince avec le corps' intervient à la fin de l'opération, et le chirurgien peut retirer l'articulation (si besoin est) en faisant glisser la pince sur le globe de l'articulation (13). Deuxièmement, pour augmenter la stabilité, la hauteur de la broche excentrique a été réduite. Ainsi, le bras de chargement peut être raccourci, ce qui permet au chirurgien de fixer le globe de l'articulation (13) avec plus de force pour augmenter la stabilité. Cette pince polyplanaire peut fixer les fragments dans différentes combinaisons ou angles sans mettre en oeuvre l'articulation. Il peut également déplacer les fragments de l'os. Au moyen d'un nouvel appareil de distraction-compression, le chirurgien et le patient peuvent aisément distracter ou comprimer les fragments de l'os uniquement en tournant l'écrou d'extension (7) dans le sens ascendant jusqu'à entendre un déclic. Aucune autre manoeuvre de stabilisation ou autre n'est nécessaire. Ce procédé permet de réduire le temps d'adaptation du patient et la durée de son hospitalisation.
