Cadwell serves hospitals, clinics, and home-care settings with global distribution, supported by dedicated customer service, online training resources, and educational workshops.

Proprio manufactures Paradigm™, an FDA-cleared surgical navigation and AI guidance platform designed for intraoperative spinal surgery applications. Paradigm combines advanced sensors, computer vision, and light-field imaging to deliver real-time 3D anatomical visualization and measurement without ionizing radiation. The platform performs continuous segmental registration, adapting automatically as patient position, table, and surgical field change—eliminating the need for repeated intraoperative imaging. Key capabilities include on-demand radiation-free measurements of spinal alignment, disc height, and segmental angles; implant-agnostic guidance; and passive collection of structured surgical data throughout preoperative, intraoperative, and postoperative phases. Clinical data show approximately 1+ hour saved per surgery, 30% increase in reimbursements, 3-4x decrease in revision surgeries, and 10x reduction in radiation exposure. Proprio has received multiple FDA 510(k) clearances, including a third clearance for dynamic 3D segmental viewing. The platform generates standardized data enabling longitudinal learning across hospital systems, objective case documentation, training initiatives, and quality programs. Proprietary AI models, trained on cases from hundreds of surgeons, enable continuous system learning. Paradigm is designed to reduce reliance on intraoperative 3D imaging and mobile CT, potentially lowering long-term capital planning costs while optimizing surgical workflows and improving institutional surgical performance metrics.
