Advanced Sacroiliac Joint Fusion Implants and Methods

The present inventive concept relates to improved sacroiliac joint fusion implants and methods that enhance the stability and efficiency of posterior SI joint fusion procedures.

The original patent describes a sacroiliac joint implant system, but it lacks adaptability to varying SI joint anatomies and has limited bone growth facilitation. The new inventive concept addresses these limitations by introducing a reaming guide with a dynamic cutting surface, a fusion plate with an integrated graft material holder, and a porous material facilitating bone growth.

The advanced sacroiliac joint fusion implant system comprises a reaming guide with a dynamic cutting surface, which adapts to varying SI joint anatomies, ensuring accurate and efficient tool path definition. The fusion plate features an integrated graft material holder, allowing for optimal bone growth facilitation. The porous material used in the fusion plate promotes bone growth across the plate, enhancing the overall stability of the joint. The inventive concept also includes methods for posterior SI joint fusion, which utilize the advanced reaming guide and fusion plate.

The new inventive concept introduces a reaming guide with a dynamic cutting surface and a fusion plate with an integrated graft material holder, which are not present in the original patent. These features, combined with the porous material, provide a significant improvement in stability and efficiency over the prior art.

Alternative embodiments of the inventive concept could include a reaming guide with a built-in navigation system, adjustable windows for holding graft material, or varying porous material structures to facilitate bone growth. These variations would ensure broad conceptual coverage and adaptability to different clinical scenarios.

The advanced sacroiliac joint fusion implants and methods have significant commercial potential in the orthopedic and spine surgery industries, addressing the growing demand for minimally invasive and efficient joint fusion procedures.
