This invention relates to an adjustable
lumbar lateral anterior wedge fusion device, comprising a first body, a second body, a first support rod and a second support rod rotatably mounted at one end on the first body and the other end on the second body, a third support rod and a fourth support rod rotatably mounted at one end on the first body and the other end on the second body, and an angle adjustment device for adjusting the tilt angle of the second body. This invention, through its angle adjustment mechanism, can achieve both anterior-posterior and
lateral angle adjustments, as well as multi-angle adjustments of the second body, resulting in better fit and stability between the device and the upper and lower vertebrae.
