Key Findings 1 Despite the spinal implants market being a mature market, increasing patient needs, end user demands and stringent regulatory approvals are pushing for continuous research and development of biomaterials for better biocompatibility and enhanced healing and clinical outcome. 2 Incremental innovations are commonly seen within the biomaterial market for spinal implants. Strict regulatory approvals does not permit the introduction of new biomaterials within the industry and hence researchers and developers prefer to combine existing biomaterials or incorporate biologics into commercially existing spinal implants. 3 There is an emergence of tissue enginerring and stem cell research as solutions for developing advanced spinal implants. Gene therapy and engineered stem cells in conjunction with biomaterials are expected to have huge impact for treating tissue and bone loss. 4 5 Surface coating or modification is a big industry within the spinal implants facilitating osseointegration, minimizing friction between implantable components, and bolstering fatigue resistance. Porous titanium, cobalt-chromium, bioactive ceramics are highly used as coatings for spinal implants. The spinal implants manufacturers are also looking into biologics coating. Advances in nanotechnology, additive manufacturing technologies and 3D printing are opening new frontiers particularly in the development of next generation spinal implant biomaterials and regenerative medicine strategies. This will enable the use of value-added design spinal implant device manufacturing sector. 6 Future developments reside in the synthesis of bio-inspired materials through processing methods and strategies that are characteristic of biological systems. These involve nanoscale self-assembly of the components and the development of hierarchical structures 8

Technology Snapshot Spinal Implants Products Non-Fusion Based Classification Motion preservation technologies Artificial Discs Annulus Repair Dynamic Stabilization Definition Also called as disc replacements, disc prosthesis or spine arthroplasty devices, they are implanted in the spine to enable the person carry loads and allow spinal motion. Annular repair devices are reconstruction implants that are utilized to seal the opening made for a discectomy surgery. Also called soft or flexible stabilization devices they are used for stabilizing the spine while maintaining natural anatomy and motion. Spinal Implants Nucleus Replacement Facet Arthroplasty These implants are used to replace the disc nucleus in discs where the structure still remains intact. They are used to fill the disc following discectomy. These implants are used to restore the facet joints that have been damaged by spinal degeneration devices. Interbody fusion These implants are used in spinal fusion procedures to preserve foraminal height and decompression. Fusion- Based Motion restriction technologies Spine Fixation Spinal Bone Stimulators These implants are used for vertebrae fixation in cases of fracture, deformity, and degenerative disorders. Bone growth stimulators are implanted during spinal fusion surgery to induce osteogenesis and promote fracture healing. 11
Biomaterials used for Spinal Implants Spinal Implants and Biomaterials Spinal implants are devices that are used to correct spinal deformities, facilitate fusion, and stabilize and strengthen the spine. Some of the disorders treated using spinal implants are degenerative disc disease, scoliosis, kyphosis, spondylolisthesis, and fracture. They are made from materials that are biocompatible and can provide optimal spinal stabilization and strength. Some of the biomaterials used for fabricating spinal implants are metals, polymers, ceramics, and bio-derived materials. Classification of Biomaterials for Spinal Implants Metallic Biomaterials Polymers Bioceramics Metals are extensively used for spinal implants owing to their superior strength. Advances in refining technology have led to the development of corrosion resistant metals and alloys. The metals are made bioactive through surface modification techniques. Porous metallic biomaterial is currently being looked into for providing space for bone in growth and vascularization. Combination Products Biodegradable or resorbable polymers exhibit controlled breakdown and absorption of polymer chains within the body. Mechanical strength for bioabsorbable polymeric implants is enhanced through a self-reinforcing process. Biodegradable polymers reduce stress shielding effects and the need for subsequent surgeries for artefacts removal. Bioinert ceramics are used as spinal screws and plates. Bioactive ceramics are used as coatings for metallic spinal implants. Biodegradable ceramics are used for fusion surgeries. The porous structure of ceramics resembles bone tissue structure, and hence is used in conjunction with other materials and also as synthetic bones. Stem Cells These are composite products of either metal, polymer, or ceramics with bioengineered structures or biomaterials such as allografts, autografts, demineralized bone matrix, growth factors, and poly morphogenic proteins. These combination implants are used to stimulate molecular responses and induce bone formation. The natural biomaterials provide good osteointegrative and osteoconductive properties. Stem cells are being researched as biomaterials for spinal implants for addressing pathophysiology of the spinal cord injuries such as neuronal regeneration and anti-inflammatory. Stem cells can be injected or surgically implanted. They are still in pre-clinical studies and their success in treatment will depend on the use of multiple strategies such as rehabilitation. 12
