From diagnosis to therapy: Under the supervision of Florian Frisee M.
For spinal support or correction, a device comprising one or more support bars positioned along the spinal column is used, and fixed to certain vertebrae by implants.
Said implants are fixed at one end to the bars and at the other end to the vertebrae by bone anchorage means, composed of a hook supported by a vertebra or of a threaded part screwed inside the vertebra itself, for example at the pedicle.
In such devices, it is known to use bars inserted into the body of the implant via an opening, either simply through the implant or in the form of a channel opening onto a side, said channel possibly opening onto the side or rear on the top of the implant.
In the case of a closed type implant, the insertion of the bar must most frequently be carried out after the fixation of the implants, which requires the delicate operation of deforming the bar as it is inserted into the different implants.
In the case of an implant with a side or rear opening, the bar-implant fixation may be obtained by means of an intermediate part referred to as a clamp. Said clamp is formed from a ring which is inserted around the bar and fixed to it by a clamping screw, said clamp in turn being inserted into the opening of the implant longitudinally along the axis of the bar.
Once the clamp is inserted longitudinally in the implant, as in patent FR 2the clamping is obtained by a conical shank and secured by an additional part referred to as a safety lock. Failing a safety lock, as in patent EP 0the clamping is secured by two additional screws clamped onto the bar via the clamp and the body of the implant.
The patent US 5 The preamble of claim 1 is based on this document. The rod is maintained in a hole of each vertebra screw thanks to a set-screw screwed in a threaded part of the vertebra screw. The rod has a diamond knurling pattern on its outer surface, in order to avoid its slipping.
There is not a transversal bearing surface on the rod. Another possibility consists of inserting the bar directly into an implant with a rear open channel, as in patent FR 2and damping this bar with a threaded plug securing the bar by means of a curved blade to provide a satisfactory contact surface.
In both cases, this assembly of several parts is intended to ensure the reliability of the clamping, but represents a complexity and size liable to render implantation delicate, particularly at the junction of the lumbar and sacral regions where only a small amount of space is available due to anatomical conditions.
The presence of small parts to assemble during the operation involves the disadvantage of more delicate manipulations and the risk of said small parts being disseminated in the operative field. The aim of the present operation is to remedy the drawbacks of the prior art by proposing an osteosynthesis device enabling easier adjustment on the operative site and more rapid implantation.
Another aim is to propose a more compact osteosynthesis device. Another aim is to propose an osteosynthesis device comprising a reduced number of separate parts during implantation. Another aim is to propose an osteosynthesis device wherein the clamping or fastening shows improved reliability.
The invention, with its characteristics and advantages, will be seen more clearly upon reading the description with reference to the appended figures wherein: The osteosynthesis device according to the invention uses the principles of the prior art in terms of the possible application.
It can be adapted to screw or hook implants and will be represented here in the case of screw, or pedicular screw, implants.The Ilizarov method is a valuable alternative option to more conventional methods in the treatment of severe wound contamination and in cases of soft tissue or bone loss.
Ilizarov named his method transosseous compression-distraction osteosynthesis and formulated its principles [1, 2].

Methods. Sixty-seven patients (mean age, 41 years; range, 22–76 years) of this prospective study were divided into two groups according to treatment randomly: ORIF group (plate osteosynthesis) and IMN group (intramedullary nail).
