Multijoint Fusion Implants and Methods for Various Orthopedic Applications
Legal Citation
Summary of the Inventive Concept
The inventive concept expands the core technology of sacroiliac joint fusion implants to address a broader range of orthopedic applications, including osteoporotic fractures, tendon damage, scoliosis, temporomandibular joint disorders, and ligament damage.
Background and Problem Solved
The original patent disclosed sacroiliac joint fusion implants, which effectively addressed lower back pain and pelvic instability. However, the limitations of this technology were confined to the sacroiliac joint. The new inventive concept addresses the need for a more versatile and adaptable fusion implant system that can be applied to various orthopedic applications beyond the sacroiliac joint.
Detailed Description of the Inventive Concept
The multijoint fusion implant system comprises a porous material to facilitate bone growth across the joint, at least a pair of pedicle screws, and a rod extending across the joint. The system can be adapted for posterior wrist fusion, anterior spine fusion, posterior temporomandibular joint fusion, and other orthopedic applications. The porous body and protrusions promote contact with the surrounding bone, ensuring a stable and durable fusion.
Novelty and Inventive Step
The new claims introduce a novel application of the sacroiliac joint fusion implant technology to various orthopedic joints, demonstrating an inventive step beyond the original patent. The adaptation of the core technology to address different orthopedic applications and problems constitutes a non-obvious advancement.
Alternative Embodiments and Variations
Alternative embodiments may include variations in the porous material, pedicle screw design, and rod geometry to accommodate specific joint anatomy and fusion requirements. Additionally, the system could be modified to incorporate sensors, actuators, or other features to enhance fusion monitoring and post-operative care.
Potential Commercial Applications and Market
The multijoint fusion implant system has significant commercial potential in the orthopedic industry, with potential applications in osteoporotic fracture treatment, tendon repair, scoliosis correction, temporomandibular joint disorder treatment, and ligament damage repair. The target market includes orthopedic surgeons, hospitals, and medical device manufacturers seeking innovative solutions for various orthopedic applications.

Section 103 Obviousness Analysis (PHOSITA)
Field of Art
Orthopedic surgical implants and medical device design, specifically focusing on joint fusion technologies involving biomechanical stabilization and bone growth promotion techniques
Person of Ordinary Skill (PHOSITA) Profile
A biomedical engineer or orthopedic surgical device designer with expertise in implant materials, biomechanical fixation methods, and understanding of joint fusion principles across multiple anatomical regions
Obviousness Rationale
A PHOSITA would recognize that the core sacroiliac joint fusion technology represents a generalizable approach to joint stabilization that can be systematically adapted to other anatomical regions with predictable modifications. The fundamental design elements of pedicle screws, porous bone-growth-facilitating materials, and stabilizing rods are transferable across different joint contexts. The variations disclosed demonstrate routine engineering adaptation rather than non-obvious innovation.
