New description: [New technical field] This case is related to a kind of cage, especially a modular bone fusion cage, which is used for the treatment of disc disease, such as anterior or posterior lumbar fusion surgery. ^ The implant, whose function is to restore the height between the vertebral bodies and to support the anterior vertebral body. [Previous technique] lumbar interbody fusion is the current instability of the lumbar spine caused by the treatment of intervertebral disc disease. The bone fusion is often used to replace the diseased intervertebral disc. The surgical method can be divided into posterior implantation and anterior implantation. After the operation, the ligament or soft tissue resection will increase the instability of the lumbar vertebrae, so it needs to be additionally in front or side of the surgical resection site. The bone plate is fixed, or the stability of the surgical resection site is increased by the posterior vertebral pressure, so as to improve the rate and success rate of bone fusion, so that the patient can return to daily life as soon as possible. The most common shape of the opening vertebra f is: (1) cylindrical, (2) clinical failure of the kidney during spinal fusion surgery, often causing slow growth of f or loss of extremity of the cage, the vertebra after surgery Cage == forced and (3) problems can cause bone fusion to defeat, back to the opposite *. After the above plate is fixed, the connection between the front and the vertebral body can be improved, so that the sliding cage and the bone plate fixator of the cage are not difficult to be overcome by the medical equipment industry.
