Various methods, devices, and systems are disclosed that facilitate easier and more compact implantation of osteosynthesis devices. In some embodiments, implants are screwed into two vertebrae and a plate is used to hold and displace the spine. In some plate embodiments, at least one longitudinally elongated opening is disposed at one end of the plate and partially opening onto an edge of the plate. In some plate embodiments, at least one longitudinally elongated opening is disposed at one end of the plate having a portion sufficiently large to be inserted without disassembly in the fixation means of an implant already screwed into the spine when the fixation means are already assembled.

Plate for osteosynthesis device and method of preassembling such device

Plate for osteosynthesis device and preassembly method

The present invention relates to an osteosynthesis device, particularly for spinal support or correction, enabling easier and compact implantation, that can be particularly used in the case of implantation via the anterior approach, and a preassembly method for such a device. Said device comprises implants screwed into two vertebrae and one plate characterized in that the plate is joined to at least one implant by attachment structure able to hold said plate without preventing the implant from rotating on its screwing axis, or without preventing a specified clearance of the plate with respect to the implant. In this way, said attachment structure make it possible to continue screwing the implant, or adjust the position of the plate after the plate has been on the implant.

Progressive approach osteosynthesis device and preassembly method

An osteosynthesis device is proposed, particularly for spinal support or correction, enabling easier and compact implantation, that can be particularly used in the case of implantation via the anterior approach, and a preassembly method for such a device. In various embodiments, the device comprises implants screwed into two vertebrae () and a plate () used to hold and displace the spine. In various embodiments, the plate () comprises on at least one of its ends at least one longitudinally elongated opening, the opening having firstly at least one part opening onto an edge of the plate, or one part of a sufficiently large size (s) to be able to be inserted without disassembly in the fixation means of an implant () already screwed into the spine when the fixation means are already assembled.
