"content": "Adoption is gated by surgeon familiarity with a manufacturer’s screw design and instrumentation; switching requires retraining, inventory swaps, and new tray reprocessing, creating high switching costs. Supply risk centres on certified titanium rod shortages and single-site sterilisation contractors; control points sit with OEMs holding proprietary screw-plate interfaces and with hospitals whose value-analysis committees gate adoption. Regional variation shows U.S. reliance on consignment stocking, EU preference for reusable trays, and APAC acceptance of local low-cost polymer systems."
