Core offering

Kuros Biosciences develops, manufactures and commercializes the MagnetOs family of synthetic bone graft substitutes powered by proprietary NeedleGrip submicron surface technology. The portfolio comprises Granules, Putty, Easypack Putty, Flex Matrix and the MIS Delivery System, used by spine, extremities and trauma surgeons to fill bone voids and promote fusion in spinal fusion, foot/ankle, and orthopedic trauma procedures. Products are sold through direct sales, strategic distribution agreements (including Medtronic) and regional distributors across more than 20 markets.

Product overview

Kuros Biosciences develops and commercializes the MagnetOs family of bone graft products powered by NeedleGrip submicron surface technology. The portfolio consists of five main formulations: MagnetOs Granules (the foundational granular form), MagnetOs Putty (moldable formulation), MagnetOs Easypack Putty (syringe-dispensed formulation), MagnetOs Flex Matrix (matrix form for interbody fusion), and MagnetOs MIS Delivery System (minimally invasive delivery instrument). All products are based on biphasic calcium phosphate with the proprietary NeedleGrip surface technology that stimulates bone growth by polarizing macrophages to the M2 pro-healing phenotype. The products serve spine, extremities (foot and ankle), and trauma markets with various formulations optimized for different surgical approaches and anatomical regions.

Broad incumbents

• Medtronic (Spinal & Biologics division): The global spine market leader with a broad spinal hardware and biologics portfolio (including Infuse BMP). Comparable to Kuros as both a direct competitor in orthobiologics and the strategic partner distributing MagnetOs in the US since January 2025.
• DePuy Synthes (Johnson & Johnson): Major spine, trauma, and extremities franchise with a broad bone graft and biologics offering. Comparable to Kuros because it competes across the same spine, extremities, and trauma markets and employs several Kuros senior leaders (e.g., incoming COO I.V. Hall, CBO John Griffin, SVP Todd Stohler).
• Stryker (Spine & Orthopaedics): Diversified medtech with spine, orthopaedics, and biologics offerings (including the legacy Wright Medical extremities portfolio). Directly comparable to Kuros in spine hardware adjacencies and extremities bone graft markets, and a known employer of several Kuros senior commercial leaders.

Direct peers

• Orthofix Medical (SeaSpine): Spine and extremities-focused medtech with bone graft and biologic substitutes (including the Trinity ELITE allograft line). Highly comparable to Kuros as a US-listed pure-play in spine/extremities orthobiologics, and recent employer of SVP Joe Ross.
• NuVasive / Globus Medical: Pure-play spine companies with overlapping hardware, MIS delivery, and biologics offerings (Globus acquired NuVasive in 2023). Comparable to Kuros as direct competitors in spine fusion procedures and in MIS delivery technology where Kuros's new MagnetOs MIS Delivery System is positioned.
• Integra LifeSciences: Spine, orthobiologics, and extremity-focused medtech with bone graft substitutes (e.g., Accell Evo3, Integra OS). Comparable to Kuros as a competitor across spine and extremities bone graft indications, and a previous employer of SVP HR Laura Rosa.
• Alphatec Holdings: US-listed pure-play spine company focused on MIS and lateral fusion approaches. Comparable to Kuros as a spine-focused competitor with overlapping surgeon call points and a similar growth-stage profile in the US spine market.
• Bioventus: Orthobiologics company with bone graft substitutes (e.g., Signafuse, BioMatrix), pain therapies, and restorative treatments. Directly comparable to Kuros as an orthobiologics competitor addressing spine fusion and extremities bone healing indications.
• Xtant Medical: Pure-play orthobiologics company offering allograft and synthetic bone graft products (e.g., OsteoVive, 3Demin) for spine and trauma. Comparable to Kuros as a direct competitor in synthetic and traditional bone graft substitutes targeting spine and extremities surgeons.

Emerging players

• SI-BONE: Specialized spine device company with proprietary triangular implants for sacropelvic conditions. Comparable to Kuros as a small-cap, evidence-driven spine medtech addressing niche but adjacent indications and competing for surgeon mindshare in academic spine centers.
