Description
Technical Field
The invention relates to the technical field of orthopedics treatment, in particular to a spinal orthopedics implant with an extension mechanism.
Background
Spinal advancement is a term used to describe the sliding of one vertebra forward over the vertebra below it. This often occurs because of the slipping of the spine in the upper vertebrae. The two main parts of the spine hold vertebrae in alignment, including the intervertebral discs and facet joints. When the spondylolisthesis occurs, the facet joints can no longer hold the vertebrae. The disc may slowly elongate under increased pressure and allow the upper vertebrae to slide anteriorly. In most cases, the elongation of the disc allows only a small amount of anterior sliding.
To alleviate chronic back pain, the disc is removed, along with all or a portion of at least one adjacent vertebra. The implant is then inserted to facilitate fusion of the remaining bone anatomy. However, in the prior art, the shape of the spinal implant is not extendable and deformable, so that the spinal implant for filling the space left by the removed intervertebral disc may not have sufficient strength to support the spinal column, and after the spinal implant is implanted between the spinal bones, it is generally necessary to fix the two spinal bones by adding pedicle screws in order to secure the adjacent two spinal bones, which results in a deeper surgical wound depth and increased surgical pain for the patient during the later removal.
