Multijoint Fusion Implants and Methods for Various Orthopedic Applications

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.

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.

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.

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 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.

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.
