Definitions

  • the present invention concerns an external stabilizer for treatment of broken bones, especially joint bones.
  • the Iliazarow's stabilizers assure good stabilization and reposition of bone stumps, however they have large overall dimensions and due to a lack of movable joint they can not be used for treatment based on functional method.
  • the object of the invention is to elaborate the stabilizing set - up, enabling the correlation of displacements, stabilization of bone stumps and functional treatment in motion, with possibility of accomodation the elements of said set - up corresponding to a kind of bone break.
  • the stabilizer consists of an assembly of guiding rail and connector with bone screws, what constitutes the prior-to-joint assembly. It has a possibility of adjusting the position of rails in relation to connector and of bone screws in relation to connector.
  • the prior-to-joint assembly in connected by a movable joint with an out-of-joint assembly, which depending on the location constututes symetrically the same out-of-joint construction or a specific construction intended for treatment of broken elbow or ankle joint.
  • the stabilizer composed of prior-of-joint assembly, having joint part replaced with the openings for bone screws.
  • Pig. 1 shows schematically a longitudinal cross - section of the device
  • Fig. 2 shows the device in a side cross - section
  • Fig. 3 is a front view of the connector with bone screws
  • Fig. 4 is a longitudinal cross - section of priorto-joint assembly with closed section
  • Fig. 5 is a side view of the assembly as seen from Figure 4;

  • Fig. 15 is a longitudinal cross - section of the stabilizer for treating the shaft of long bones;
  • Fig. 16 is a side view of the stabilizer.
  • the stabilizer consists of prior-to-joint assembly as shown of Fig. 1 - 3 and composed advantageously of twoquide rails 1 , 2 having preferably a circular cross - section, on which there is embedded a longitudinal connector 7, having a possibility of axial movement. Said movement is generated by adjustment means 18, preferably in the form of a nut, directly or by means of elastic elements 17, eg. springs.
  • adjustment means 18 preferably in the form of a nut, directly or by means of elastic elements 17, eg. springs.
  • the damping elements eg. of rubber /not shown/.
  • the quiding rails 1, 2 connected with a mechanical joint 3 having a characteristic approaching the human joint on which it is installed.
  • the apertures having the shape and the size approaching the quiding rails 1, 2.
  • the openings 12 in which the bone screws 14, 15, 16 are fixed.
  • On of bone screws 15 is shifted transversely in transverse oval orifice 11, what enables its displacement in relation to an axis of the assembly, as well as compensation of bone stumps displacements.
  • the shifting of said bone screw is realized by means of adjusting screw 32.
  • the blocking of bone screws takes place by means of blocking screws 26 or bolts 27.
  • Figs. 4 - 7 In order to obtain the larger stiffness and strenght of the assembly, especially in treatment of lower limb, advantageously there is applied the assembly as shown in Figs. 4 - 7, in which the connector 7 is places shiftably between external quide rails 1, 2 having a shape approaching the C - shaped rail 28 /Fig. 7/ or preferably having the closed cross - section rail 29 /Fig. 6/.
  • the axial shifting is generated by the rotation of a tightering screw 30.
  • the rails 28 or 29 are connected with the joint 3 by means of a hall joint 33 a blocking serew 34.
  • the stabilizer As shown in Figs. 12 - 14. It consists of a typical prior-to-joint assembly /not shown/, connected by means of an axial joint with the out-of-joint assembly, formed of an arcuately bent element 35, the proximal end thereof constituting the part of stabilizer's joint, and the second wide end has apertures for screws 40, 41. Said screws enter the openings 37, 38 of a plate 36 and enable its shifting. Unscrewing said screws enables the reposition of the break, and the blocking makes the reposition durable. At the end of the plate 36 there is placed a rotatable rod 39 having transverse openings 43, 44 in which there are embedded the bone screws, blocked by means of a nut 42.
  • stabilizer For the treatment of ankle joint there is applied stabilizer as shown in Figs. 10 and 11. It consists of prior-to-joint assembly /not shown/, connected by means of an axial joint with out-of-joint assembly, constructed of a connector 45, constituting at one end the part of the joint, and at the other end constituting the leading for a quide 46. On its ends there are shiftably placed the elements 47, having the openings for the bone screws. All elements are blocked by means of the bolts.
  • Said stabilizer is constructed from a connector 48 having a controller means 50, bone screws 48 and a part of quiding rails constituting an prior-to-joint assembly.
  • the quiding rails are connected inseparably with element 52, being equipped with bone screws.

Abstract

Un stabilisateur utilisé dans le traitement d'os fracturés constitue un fixateur dynamique de traitement de fractures au voisinage de diverses articulations osseuses. Ledit stabilisateur se compose d'un ensemble proximal constitué du connecteur (7) pouvant être décalé sur des rails (1, 2) à l'aide d'un moyen de réglage (18) par l'intermédiaire de ressorts (17). Les rails (1, 2) sont connectées à l'articulation (3) du stabilisateur dont l'axe coïncide avec l'articulation à couvrir. Dans le connecteur (7) sont formés des orifices destinés à des vis (14, 15, 16) à os, introduites dans les os à angle droit ou à n'importe quel autre angle requis pour accroître la stabilité. Le repositionnement s'effectue par décalage latéral de la vis (15) à os dans un orifice oval (11) au moyen d'une vis de réglage (32). L'ensemble distal peut être identique à l'ensemble proximal, où il peut prendre diverses formes en fonction de l'articulation à couvrir.
