AI Technical Summary
Traditional expandable intervertebral spacers lack variability in lordotic expansion, relying on a single actuation mechanism that compromises between bone support, expansion height, and mechanical advantage, limiting intraoperative flexibility in spinal correction procedures.
An interbody implant with independently adjustable anterior and posterior expansion mechanisms, utilizing threaded screws and wedges to allow for concurrent or sequential expansion, enabling variable lordotic angles and heights to accommodate different anatomical needs.
The solution provides greater flexibility and precision in spinal correction by allowing surgeons to adjust expansion independently, enhancing the ability to achieve desired spinal alignment and support.
