DEVICE FOR STABILIZATION IN vertebral motor segments SPONDILOLIZNOM spondylolisthesis

摘要

The invention relates to medicine, namely to submersible devices for surgical treatment spondiloliznogo spondylolisthesis in the lumbar spine, and can be used in traumatology and orthopedics and neurosurgery. The design of the device is represented by an implant for fixing a displaced vertebra with a locking element made of BT brand titanium alloy 14 or alloy based on iron 12X18H9T. The implant has a grooved bearing surface and a shaped groove extending from the anterior faces towards the center of the lower supporting surface, through which via an input device for reposition locking element. The implant is made of 15 sizes for intraoperative select the desired size of the implant. The achieved result - an increase reliable stabilization damaged spinal segment when spondiloliznom spondylolisthesis prevent cracking due to the introduction of the implant retaining member, preventing fatigue fractures and optimal implant size selection, with no complicated operating intake and increased trauma surgery. 2 ill.
