Definitions

  • the present invention relates to an external fixator for bone surgery, i.e. for reducing tibia fractures in the periarticular joint area of the knee for adjustment of equinus foot deformities.
  • External fixators have been used in bone surgery for a long time for stabilising fractures or for eliminating traumatic and/or congenital deformations.
  • Such apparatus essentially consist of a plurality of pins which can be inserted into bone fragments in such a way as to have an end coming out the muscle and the epithelial tissues, which pins are stably and removably secured to an external rigid structure of suitable configuration.
  • external fixators a distinction is made between two large families, i.e. that of monolateral apparatuses and that of the circumpherential or bilateral apparatuses.
  • Examples of monolateral fixators are the external axial fixators, such as those of the series 10000 manufactured by Orthofix of Bussolengo, Italy, that substantially consist of a pair of end clamps connected to a central body of adjustable length by means of lockable ball joints which make it possible to set them.
  • Such external axial fixators have the advantage of being very easily and rapidly mounted owing to the fact that the screws must be applied to one side only and are simple to fix thanks to a large contact surface offered by the two halves of the clamps.
  • the screws have dimensions such as to allow the transmission of bending and shearing loads to the bone tissues.
  • fixators of circumpherential or bilateral type have as a first prototype the model of fixator designed and first employed by llizarov, which fixator comprises at least two rigid support rings peripherally arranged with respect to the bone fragments to which it is possible to removably fix at diametral positions one or more Kirschner wires inserted in the bones and having both their ends projecting out from the muscle and the epithelial tissue of the limb.
  • the support rings can be mutually connected by longitudinal rods or bars adjustable in length and inclination so as to vary their mutual distance and orientation.
  • the bone wire used in such circumferential fixators has the advantage of transmitting stresses in a perfectly balanced way and of being insertable into more delicate or osteoporotic bone tissues in periarticular areas with smaller risk of affecting highly vascolarized tissues. Owing to the reduced diameter of the wires it is possible to increase their number so as to distribute the circumferential load in a uniform manner.
  • each single wire can apply a concentrated load to the bone tissue into which it is inserted, and thus it can cut it or affect its adhesion. This reduces endurance and stability of the device with respect to an external monolateral fixator.
  • Fixator devices of a hybrid type have also been designed in which axial structures supporting one end of radial screws or pins extending out of the bone and the epithelial tissue are anchored to the support rings mutually connected by means of bar that can be elongated and bent.
  • a main object of the present invention is to eliminate or at least to mitigate the drawbacks referred to above by providing an external fixator apparatus which makes it possible to simplify the operations of application thereof and to reduce the operational times with respect to the conventional circumferential or hybrid devices.
  • a further object is that of providing an external hybrid fixator which makes it possible to obtain a more balanced partly circumpherential distribution of the loads with respect to the conventional monolateral devices.
  • an external fixator device for bone surgery comprising a plurality of pins that can be inserted into a bone fragment such that at least one end thereof projects outside the peripheral muscle tissues, and a rigid frame arranged to stably support the said pins at their outer ends while keeping them at an adjustable distance from one another.
  • the device is characterised in that the said frame comprises at least a first element arranged to removably and selectively clamp one end of a first group of pins extending from one side only with respect to the bone, a second element arranged to clamp a second group of pins extending from opposite sides with respect to the bone, and connecting means extending between the said first and second elements to change their orientation and their mutual distance.

  • the clamp 2 comprises two parts or jaws 4, 5 which are substantially semielliptic in cross section and mutually articulated by means of a hinge 6.
  • the parts 4, 5 on their facing surfaces are provided with a series of transverse seats or grooves 7 having a substantially semicircular cross section and arranged to cooperate with the ends projecting out of the epithelial tissue of a first group of screws V which can be inserted into a bone stump M' with substantially coplanar axes.
  • the two parts 4, 5 can be mutually tightened through a socket head screw 8 by means of a suitable wrench.
  • Part 4 has a lower extension 9 provided with side lugs having slotted holes 10 for connection to the second support element 3.
  • the support element 3 is illustrated in greater detail in Figs. 3, 4 and 1 1 and comprises an annular rigid structure having a substantially U-shaped cross section overturned by 90° and an inwardly directed rounded end with parallel flat surfaces.
  • the ring 3 is formed with a series of radial holes 1 1 which are slotted in circumferential direction and delimit stiffening ribs 12, as well as a series of axial holes 13.
  • the annular structure comprises two half rings 3' , 3" connected to each other at their ends by means of snap coupling pins 14, 15.
  • the pin 14 is secured to the half ring 3' by means of a transverse locating peg 1 6 extending through a slotted hole 1 7 and has a ground end thereof that can be snugly fitted into a hole bored in the opposite half ring 3".
  • the pin 1 5 is secured to the half ring 3" by means of a locating peg 18 and is removably snap coupled to the half ring 3' through a ball 19 seated in a recess and urged outwards by a spring 20 to snap enter a bore 21 formed in the half ring 3' .
  • the annular support structure 3 can be positioned around the patient's limb without the need of inserting it from one end thereof, but by simply arranging one of the two half rings 3', 3" below the patient's limb in the desired position and successively snap coupling it with the other half ring by direct insertion with a very simple operation.
  • the ring 3 supports in diametral position one or more stainless steel Kirschner's wires F inserted into a second bone fragment M" of the fracture so as to have both its ends coming out from both sides of the limb.
  • expansions E e.g. frustoconical in shape
  • expansions E can be provided towards one of the ends of the wires F and can be inserted into flared limit recesses formed in radial bores of the ring 3.
  • the other end of the wire F can be locked and tightened by means of a suitable clamp 23 illustrated in more detail in Figs. 10a, 10b, 10c and 10d comprising two opposite portions 24, 25 provided with dovetail lugs that can cooperate with the surfaces of the ring 3 by means of a screw 26.
  • a pin 28 is rotatably mounted in the clamp 23 and has a through hole 29 for the insertion therein of the free end of the wire F with the expansion E abutting against the ring 3. By rotating the pin 28 the wire F is tightened and held within the through hole 29. The end in excess of the wire can be cut to size by the surgeon.
  • the clamp 2 is suitably anchored to a second annular element 30 similar to the first element 3 and possibly having different dimensions for fitting to the dimensions of the limb so as not to interfere with the limb.
  • the support element 30 may comprise easily couplable half rings 30', 30" or can be incomplete, e.g. extending through an arc of about 5/8 of a circumference so as to be inserted onto a limb without problems thereby avoiding subsequent interference, e.g. at a joint.

  • the annular elements 103, 104 are formed with circumferential holes through which Kirschner's wires can extend and axial holes for securing the spacer bars or rods 105, 106 or their respective joints 107.
