Imagine designing a brace with a fit so meticulous, it feels intuitive. Surprisingly, such a device can be realized even without the slightest bit of CAD knowledge! With TwikFit, a handbrace can be made with 3D-scan data and then morphed into a prosthetic template based on the patient’s biometrics. Various corrective processes at the scan level (scraping and angle corrections) eliminate challenges like bony prominence or too much pressure. Similarly, liners can be added to prevent friction.
Perfect fit aside, the fact that 3D prints are generally less expensive than traditional plaster cast methods, is an obvious benefit. (It is worth noting that hospitals that rely on 3D scan data for O&P require fewer certifications translating into cost-savings for the clinic side, too). The 3D scans can be stored in patient management software allowing measurements to provide medical insight into a patient’s progression, but the scan data can serve as a resource for other patients to understand fit and performance with a searchable database.
Like with most other 3D print features, the patient is able to choose between materials like color, structure or finish. In the case of a handbrace, being able to select lightweight material helps the patient avoid a heavy cast or too much pressure on the wrist or forearm. The highly-customized device leads to greater patient compliance, too—which is great for patient results.
Whether TwikFit is used for a handbrace, wheelchair, AFO, orthotics or prosthetics, Twikit remains a world leader in O&P innovation with made-to-measure medical devices.
