AI Technical Summary

Technical Problem

Existing spinal surgeries often face challenges in creating a surgical solution that minimizes the trauma of the surgery itself, particularly in the design and deployment of expandable interbody implants. The problem is that existing technologies fail to provide a surgical solution that minimizes the trauma of the surgery itself, especially in the design and deployment of expandable interbody implants.

Method used

The use of an expandable lordotic interbody implant that can be inserted into the spinal column, which includes a mechanism that minimizes the trauma of the surgery itself, and the implant is designed to minimize the trauma of the surgery itself, especially in the design and deployment of expandable interbody implants.

Benefits of technology

The expandable lordotic interbody implant minimizes patient trauma by being inserted into the intervertebral disc space in a collapsed state and then expanded to achieve a desired lordosis, providing a surgical solution that minimizes the trauma of the surgery itself.

Abstract

To provide expandable lordotic interbody implants and related methods.SOLUTION: The present disclosure relates to an expandable interbody implant that includes superior and inferior shells enclosing a control mechanism. The control mechanism includes interlocking proximal and distal cages and an adjustment screw. The adjustment screw longitudinally translates the distal cage relative to the proximal cage and thereby expands the interbody implant by pushing apart the distal ends of the superior and inferior shells.SELECTED DRAWING: Figure 1
