Definitions

  • the invention relates to an external fixator applicable in orthopaedy for treatment of bone fractures by the methods of extrafocal osteosynthesis.
  • the extrafocal osteosynthesis is applied in tube bone fractures of various types and localizations: fragmentations, oblique, heliciform, transverse, periarticular and articular fractures, regardless of the form and curve of the bone canal.
  • External fixators are used for reposition and fixation of the bone fragments in an increasing number of cases.
  • the fixator comprises an extended carrier, a great number of transosteal pins being fixed thereto using a variety of fixtures, as holders, clumps, etc.
  • the clinical applications of the fixator increase in variety when elements allowing fixation at various angles and at different fracture localizations are used. These are a variety of adjustable couplings between a minimum of two elements of the fixator.
  • a ball-and-socket joint between two elements of an external fixator is known from DE 3837228 - Fig. 4, DE 3543042 - Fig. 1 and 2, and SU 1739984, where one of the elements has a ball-shaped end coming in contact with a socket which is connected with one end of the second element, the ball being fixed in the intended position into a socket using an enveloping nut tightened on an external thread of the socket.
  • This coupling allows the two coupled elements to be positioned in space at various angles but it is not secured against sliding of the spherical surfaces resulting from a loosened screwed joint.
  • An external fixator for osteosynthesis in known from EP 0140786, said fixator comprising bone implants, bone screws for example connected with one another by at least one carrier and fixed by clamps baying clamping screws.
  • the carrier is a tube in which holes for the bone screws are made perpendicularly to the carrier's axis, along with the screw holes for the clamping screws.
  • the carriers can be directly interconnected using a compression-distraction mechanism and/or a ball- and-socket joint.
  • the ball-and-socket joint is a sphere consisting of two or three interconnected parts. Each part is provided with a tip which enters the carrier's tube and is fixed with a screw.
  • a disadvantage of this external fixator is that the clamping screws do not guarantee reliable fixation. Consequently, a load on the damaged bone, e.g. in the course of rehabilitation treatment, may cause the clamping screws to loosen or fall out since the screw holes are of small length, which may result in lower reliability and effectiveness during the treatment.
  • Another external fixator is known from PCT W097/16/28, said fixator comprising bone implants which are to be introduced into the bone fragments and are indirectly interconnected using at least one carrier with circular cross-section and riffled surface.
  • the bone implants are positioned by at least one holder and/or clamp mounted so as to allow further adjustment of the carrier.
  • the carriers are interconnected by a compression-distraction mechanism and/or by a coupling mechanism provided with a screw-type retainer to stop them in the intended position.
  • the coupling mechanism may be a ball-and-socket joint, which comprises a ball connected with a carrier and a socket where the ball is fixed using an enveloping nut tightened to a socket's thread.
  • the working surface of the ball is made of a material which differs in hardness from the one used to make the working surface of the socket, the spherical surface being of greater hardness and has sharp edges or tips.
  • a major object of the present invention is to provide a reliable external fixator guaranteeing secure fixation of each transosteal pin or screw mounted.
  • Another object of the present invention is to provide a reliable adjustable coupling between at least two elements for external fixation, said coupling allowing these elements to be positioned at various angles and in various spatial directions.
  • a further object of the present invention is to provide an adjustable coupling which, when tightened after putting the fixator in place, does not allow displacement of repositioned bones.
  • Yet another object of the present invention is to provide an external fixator securing a flexible fixation.
  • a further object of the present invention is to provide an external fixator which is technologically feasible.
  • a further object of this invention is to provide a fixator which allows the application of low distraction and compression when used as a monofixator.
  • An object of the invention is to provide a fixator which allows simple and safe positioning, non-dependent on the experience and bodily strength of the operating orthopaedist.
  • the hinge can be ball-and-socket joined comprising at least one ball element connected with a carrier or a holder on which an enveloping nut is placed, and an element with at least one socket, where the ball could be fixed using the enveloping nut, which can be connected with a carrier.
  • the working surface of the ball is made of a material inferior in hardness to the material of the socket's working surface.
  • the socket element has at least one opening towards the working spherical surface of each socket. In each opening a retainer is placed to allow change of position, the end of the retainer having a sharp tip which can penetrate into the ball's material.
  • the implants can be interconnected also by means of hinged holders.
  • Each holder includes one element of the ball-and-socket joint firmly connected with a screw-mount.
  • the compression-distraction mechanism comprises a guide with one end connected with a carrier or holder and having a thread at its outer end, an operating element tightened so as to allow displacement on the guide.
  • Said mechanism further comprises a follower with one end connected with a carrier or holder flexibly connected with the guide by a finger moving along rectilinear groove on the threaded stem of the guide. The follower is coming in a flexible contact with the operating element, so as to effectuate only an axial displacement through the guide.
  • the through-holes on the carrier are oblongue.
  • the socket element further comprises at least one pusher permitting at least one retainer to be pushed.
  • the pusher can be an adjusting screw to be tightened into a screwed hole connected with at least one retainer hole, said screw being able to come in contact with each retainer in order to push it away.
  • the fixing nut comprises a sliding screw nut with a freely rotating unreleasable compression washer mounted at one of its ends.
  • the outer face of the washer has at least one diametrical groove for the transosteal screw or pin to be fixed thereinto.
  • the screw-mount has at least one through-hole for receiving the bone crew which screw shank is threaded. From both sides of the hole fixing nuts for tightening the bone screw are provided.
  • the though-hole has bevelled edges and each fixing nut has a bevelled split end fitting to the bevelled edge of the hole.
  • fixator is simple and technologically feasible. Its use does nor require strict choice of bone screws or special skills from the operating orthpaedist.
  • the fixator allows spatial change of reposition of the bone fragments.
  • An advantage of the fixator proposed herein is that each bone screw or pin is independently fixed using an appropriately shaped nut tightened to the carrier, which guarantees greater reliability of osteosythesis since both the supporting threaded surface and the clamping surface of the bone screw are increased.
  • Another advantage is that a variety of bone screw diameters can be used along the carrier, in accordance with the therapeutical logic. For instance, screws with greater diameters can be placed farthest from the fracture to guarantee a firm support, while near to the fracture the screws may be of smaller diameter. This allows the part of the thinner screw, which is fixed into the fracture zone, to produce microvibrations as a result of external load, e.g. rehabilitation treatment. A flexible fixation is thus secured which stimulates the fracture healing process.
  • fixator by choosing the direction of clamping each screw to the hole's wall, the carrier itself can be used to obtain compression or distraction whose magnitude depends on the size of the holes.
  • the ball-and-socket joint allows initial fastening of the hinge.
  • the retainer being inactivated, its solid tip penetrates into the softer metal of the ball, thus serving as additional prevention against sliding between the parts of the ball-and-socket joint in case of unwanted external influences.
  • a reliable coupling between at least two external fixator elements is secured, with the possibility to place these elements at various angles and in various directions in space.
  • the initial fastening of the enveloping nut does not require much effort which otherwise could displace the repositioned bone fragments.
  • Final fixation of the hinge is obtained by exerting additional effort on the retainer, the direction and magnitude of this effort not leading to unwanted displacement. This is an another way to secure a simple and safe positioning of the fixator, independently from the experience and bodily strength of the ortopaedist, the reposition being guaranteed. Since no sharp edges or tips have to be made on a spherical surface, the manufacturing technology is simplified.
