Custom Spinal Fusion Devices with Built-in Anchors

This patent describes custom-made spinal fusion devices designed for a specific patient, featuring an implant placed between vertebrae and special ways to hold its anchoring parts in place.

What it covers

Based on the abstract, this technology focuses on spinal fusion devices tailored for individual patients. It includes an interbody implant, which is a piece designed to fit into the space between two spinal bones (vertebral bodies). The implant also has one or more fixation elements, like screws or pegs, that anchor it securely to these spinal bones. A key feature is the inclusion of retention mechanisms, which are special features within the implant that hold these fixation elements firmly inside their designated holes or channels. The patent also covers the methods used to design and manufacture these patient-specific devices.

What it doesn't cover

• —Does not cover spinal implants that are not custom-designed for a specific patient's anatomy.
• —Does not cover spinal fusion procedures that do not involve an interbody implant placed in the disc space.
• —Does not cover interbody implants that lack specific retention mechanisms for holding fixation elements within lumens or bore holes.
• —Does not cover generic, off-the-shelf spinal fusion devices that are not patient-specific.
• —Does not cover other types of patient-specific orthopedic implants, such as those for knee or hip joints.

The clever bit

The novelty lies in combining patient-specific design for spinal fusion with integrated retention mechanisms that securely hold the anchoring elements within the implant. This ensures a precise fit and stable fixation, which is crucial for successful spinal fusion.

Why it matters

Patient-specific medical devices are a growing trend, aiming to improve surgical outcomes by precisely matching a patient's unique anatomy. In spinal fusion, this can lead to better fit, potentially reducing complications and improving stability compared to standard implants. While this patent is very new with no citations yet, it represents a continued push towards personalized medicine in orthopedics, which could make spinal surgeries more effective and safer in the future.
