Definitions

  • This invention relates to means and methods of correcting bone deformation and, more particularly, to such means using external fixation.
  • the proposed device is designed for use in traumatology and orthopedy in changing the shape of deformed bones; in lengthening the bones and in causing new growth of bone, skin, nerve tissue, blood vessels in deficient limbs, treatment of pseudo-arthrosis and osteomelitis, flesh fractures, open ultisplintered fractures with vast damage to bone and soft tissue.
  • the device has no contra-indications in treatment of adults and, especially, of children.
  • Bone fixators wires and pins can only be immovably connected on the rings. There can be -4 to 8 rings in the device which can bring the weight of the device to 10-1*4 lbs.
  • Ilizarov 197*4 is heavy (10-1 ⁇ 4 lbs), employs many details of various shapes and purposes, and is complicated in usage.
  • the proposed apparatus is multi-purpose and based on a new concept-moving connection between ring and tension rod.

  • Wires and pins has a measurable dosage of movement.
  • the present invention permits full accurate mechanical adjustment of rotation is 36 ⁇ degrees which is an improvement over Ilizarov which requires manual adjustment of rotation.
  • Device is simultaneously doing reposition, rotation and lengthening of the bone.
  • the invention provides means and methods of correcting bone deformation comprising arched members adapted to encircle a fractured body member, straight members are adapted to connect to arched members, bone contacting members, means to connect straight members to arched members and means to connect bone contacting members to arched and straight members.
  • a principal object of the invention is to provide new and improved means and methods for correcting bone fractures.
  • Another object of the invention is to provide new and improved means, and methods for correcting bone deformation comprising apparatus wherein arched members are threaded, and wherein connecting members comprise olive members having first and second shaftways perpendicular to each other or three shaftways and means to clamp olive members to arched members, straight members and bone contacting members. Where olive connectors with two or three holes and nuts are assembled from two parts.
  • the invention comprises two arched members 1 and 2, which are adapted to encircle a body member, such as an arm or leg, for a fracture of bone B.
  • Arched members are threaded and may be 1/k OD threaded metal.
  • the members 1 and 2 may be one piece members.
  • Arched member would have to have one side having reversed threads so that Nut 5 could bring the members together to form a continuous, preferably circular member.

Abstract

Appareil de fixation osseuse externe servant à corriger des déformations osseuses. L'appareil comprend des éléments en forme d'arc (1, 2, 5) conçus pour entourer un membre fracturé, des éléments droits (3, 4) conçus pour être reliés aux éléments en arc, et des éléments (8) entrant en contact avec l'os. Le dispositif comprend en outre des éléments de raccordement (6, 7 et 9-14) servant à raccorder les éléments droits aux éléments en arc, ainsi que les éléments entrant en contact avec l'os aux éléments en arc et droits respectivement, de sorte que le dispositif présente des ajustements filetés en continu autour des éléments en arc et le long des éléments droits, et peut être mécaniquement réglé.
