create an anatomical Lumbar and sacrum spine from L1 level to sacrum, exclude pelvis in white color with intervertebral disc in light blue color model. Also create the spinal canal and foramen with nerve roots in yellow color exiting each foramen both side in each levels. At the L4-L5 levels please make it spondylolisthesis L4 over L5 Myerding grade 2 with intervertebral disc at L4-5 levels mild posterior protrude create bilateral foraminal stenosis at L4-5 level, impending to compress exiting nerve roots in L4-5 level

椎板成形板组件
椎板成形板20包括主体部分22和连接部分24。主体部分22配置为与打开的椎板接合，并维持椎板成形过程中创建的减压位置。在一个实施例中，主体部分22具有细长的矩形构型，长度约为8mm至20mm，宽度约为3mm至8mm。主体部分22可包括多个骨接合孔26，用于接收骨螺钉以将板固定到椎板和/或棘突。
主体部分22可配置为弯曲或倾斜轮廓，以符合颈椎的自然解剖结构。在一个实施例中，主体部分22的厚度约为1.5mm至4mm，在提供足够强度的同时最小化体积。骨接合孔26可为沉头孔或包含螺纹部分以接收锁定螺钉。

连接部分和耦合机构
连接部分24从主体部分22延伸，并专门配置为与侧块螺钉30接口。在优选实施例中，连接部分24包括凹槽28，其尺寸设计为接收并接合侧块螺钉30的头部32。凹槽28可形成圆柱形或部分球形腔体，具有允许插入螺钉头部32的开口。
凹槽28可包括诸如内螺纹、卡扣、卡合机构或压缩元件等保留特征，以在插入后将螺钉头部32固定在凹槽28内。在一个实施例中，凹槽28包括锁紧螺钉或锁紧盖29，其旋入凹槽28以将螺钉头部32锁定在位置，并防止愈合期间松动或松脱。
连接部分24在板20上的位置使得当侧块螺钉30以最佳轨迹和深度插入侧块时，椎板成形板20会自动定位以正确支撑打开的椎板。因此，主体部分22与连接部分24之间的空间关系对于集成系统的成功至关重要。

侧块螺钉组件
侧块螺钉30包括螺纹轴34和头部部分32。螺纹轴34配置为插入颈椎的侧块，并可具有约3.5mm至5.0mm的直径和约12mm至18mm的长度，尽管这些尺寸可能根据患者解剖结构和手术要求而变化。
头部部分32配置为与椎板成形板20的凹槽28接口。在一个实施例中，头部部分32具有大致圆柱形或球形几何形状，外径设计为在凹槽28内以最小间隙配合。头部部分32可包括沟槽、平面或纹理等表面特征，以与凹槽28中的相应特征接合，防止旋转或迁移。
头部部分32包括驱动接口36，例如六角形凹槽、星形驱动或其他合适的几何形状，允许手术驱动工具接合并旋转螺钉30以插入骨内。即使在椎板成形板20附接后，驱动接口36也可访问，允许外科医生对螺钉深度和位置进行最终调整。

Cervical laminoplasty is a surgical procedure performed to relieve pressure on the spinal cord in the cervical spine. The procedure involves creating a hinge on one side of the vertebra and opening the lamina like a door, which increases the space available for the spinal cord. Laminoplasty plates are commonly used to maintain the opened position of the lamina and provide structural support during healing.

Lateral mass screws are fixation devices used in cervical spine surgery to stabilize vertebrae and facilitate fusion. These screws are inserted into the lateral mass of the cervical vertebra and are commonly used in conjunction with rods and plates for multi-level cervical fusion procedures.

In complex cervical spine pathologies, surgeons may need to perform both decompression (laminoplasty) and stabilization/fusion (using lateral mass screws) at the same vertebral level. However, traditional laminoplasty plates and lateral mass screw systems are separate devices that, when used at

Realistic 3D model of a small deformed preserved specimen, optimized for 3D printing.

Single organism with one main spine, irregular and twisted, partially splitting near the upper body into two asymmetrical heads.

Heads are uneven, one larger and more developed, not mirrored, slightly malformed.

Body elongated but compact and partially coiled, compressed as if preserved inside a jar.

Structure biologically wrong but plausible, not clean or symmetrical.

Subtle partial rib structures, uneven and irregular.

Surface rough, aged, imperfect, with asymmetry and small deformities, no smooth or ideal anatomy.

Pose low and curved, not vertical.

Style realistic, disturbing, like an anatomical anomaly, not fantasy.

All parts connected, slightly thickened for print stability.

Clean manifold watertight mesh, solid volume.

Neutral lighting, plain background, STL ready.
