Definitions

  • the invention relates to compression screws used in the step of fracture fixation and compression during orthopedic surgical interventions in the field of medicine.
  • the invention particularly relates to allowing a stable compression by means of the designed locking system the size of which can be changed during surgical intervention, according to the case in which said compression screws are to be applied.
  • ORIF open reduction internal fixation
  • I M inter marrow
  • Compression screws are used particularly for mechanically binding bone fractures.
  • the compression screws designed so as to be a metal shaft have screw threads (sprockets) at their free ends.
  • the screw threads have different inclinations so that a compression (tightening) occurs during screwing of the screw to the bone.
  • Compression term denotes the union of the fracture as a result of moving of these bone fractures towards each other and contacting by getting closer of two bones to each other by virtue of screwing of the screw into the two bone fractures.
  • the invention relates to a multi-purpose ulna intramedullary locking nail which ensures union of the bone by fixing in segmental or single fractures of ulna bone and fixes both ends of a nail with screws by centering the fractured portion of the bone by applying through medulla of ulna bone characterized in that; the proximal body of the ulna nail (ulna nail) made of implant material, guide locking channel of the ulna nail, the compression screw hole, the oblique thread compression hole, the oval compression hole, the round fixing hole, the distal body of the ulna nail, the distal locking chutes of the ulna nail, the distal end of the ulna nail, the distal body of the ulna nail that consist of multi wires, the locking screw that performs proxi
  • the main object of the invention is to provide a stable compression at one time and with strong compressive effect by adjusting the length of the screw according to the case, without the length problem to area to be applied by means of the compression screw having the locking system which can be lengthened or shortened during the surgical intervention.
  • the object of the invention is to ensure shortening of the length of the screw by the designed locking mechanism if necessary according to the case (area) to be applied and fixing the front and rear parts of the screw in a stable manner by means of locking to each other by thread and thread housings on the male and female lock parts.
  • a further aim of the invention is to ensure both closing the gap between the fracture fragments and compressing them by contacting with each other by shortening the size of the screw after replacement to area to be applied.
  • Another object of the invention is to realize the operation without the necessity of screw replacement especially if the size of the screw is too long during the surgery. Thus, fragmentation of bone, that may occur because of multiple insertion and extraction of screw when the length of the screw is too much, is prevented.
  • Another different object of the invention is both to allow doctors to intervene in a larger number of cases by shortening the duration of surgical intervention and to ensure that the union of the bone on which compression is applied begins faster.
  • Another purpose of the invention is to both make the patient heal more quickly and minimize the screw costs by preventing the use of multiple screws due to the long or short length, during the surgical intervention.

It consists of the first part which is the front part (A) which has thread portion in front and cavity in it, and the rear part (B) which has the thread mechanism that allows the shortening of the compression screw (V) and then doesn't allow it to lengthen back by locking, on the rear side of that front part (A).

  • the compression screw (V) enters the area of the surgical intervention in one piece. If it is desired to shorten it when the size of it is too big according to the size of the area to be applied, the locking threads (5) shortens the length of compression screw (V) by moving through the thread housing (6) after rotating the screwdriver by reaching the female locking compression space (11) on the female locking (14) and from there to male locking compression space (10) on the male locking (15) by means of the screwdriver.
  • the shortened compression screw (V) will not extend back in anyway owing to the developed locking system (K). Thus, a well-developed compression will be provided.
