Summary of the Inventive Concept

The inventive concept presents a novel porous spinal implant system with optimized surface area, interconnected channels, and biodegradable coatings to enhance bone growth and fusion. The system addresses the limitations of existing spinal implants by providing a more efficient and effective solution for treating spinal disorders.

Background and Problem Solved

Spinal disorders, such as degenerative disc disease and herniation, often result in degeneration of the spinal disc, leading to chronic pain and limited mobility. Existing spinal implants have limitations, including restricted surface area for bone growth, inadequate osteoconductive material flow, and lack of customization options. The new inventive concept addresses these limitations by introducing a porous spinal implant system with enhanced features.

Detailed Description of the Inventive Concept

The enhanced porous spinal implant system comprises a body portion with at least one central opening and a plurality of micro-pores on its surface, increasing the implant's surface area for bone growth. The system also features interconnected channels that facilitate bone growth by increasing the flow of osteoconductive materials. Additionally, a biodegradable coating enhances bone growth and is absorbed by the body over time. A method for customizing the spinal implant involves scanning a patient's spine to create a 3D model, and using the model to design a porous implant with optimized pore size and distribution for the patient's specific needs.

Novelty and Inventive Step

The new claims introduce a novel combination of features, including micro-pores, interconnected channels, and biodegradable coatings, which provide a significant improvement over existing spinal implants. The inventive concept's novelty lies in its ability to enhance bone growth and fusion while addressing the limitations of existing implants.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include varying pore sizes and distributions, different biodegradable coating materials, and customized implant shapes based on patient-specific needs. The system could also be adapted for use in other orthopedic applications, such as joint replacement or bone fracture repair.

Potential Commercial Applications and Market

The enhanced porous spinal implant system has significant commercial potential in the spinal implant market, which is expected to grow due to the increasing prevalence of spinal disorders. The system's ability to provide improved bone fusion and reduced recovery times could make it an attractive option for surgeons and patients alike, potentially disrupting the existing market and creating new opportunities for growth.
