Summary

Quatro is supplied as a patient-specific prosthetic socket through professional fitting and fabrication workflows. Cascade’s ordering process calls for an order form and patient scans, reflecting the individualized nature of the device rather than a single universal size. ^[5][1]

Quorum’s digital design and engineering work supports fabrication of the socket. Fit, pressure distribution and functional use depend on the individual design and clinical fitting; the adjustable panels are a mechanical accommodation feature. ^[6][5]
