What combination of materials is commonly used for making orthosis?

The combination of plastics and metal is commonly used for making orthoses due to their favorable properties. Plastics, such as polypropylene and polyethylene, offer flexibility, lightweight characteristics, and ease of molding to the contours of the patient's anatomy. These materials can be heated and shaped to create a custom fit, which is essential for comfort and effectiveness in orthotic devices.

Metal components, typically found in the form of aluminum or stainless steel, provide strength and structural integrity to the orthosis. They are often used in areas that require more durability or load-bearing capabilities, such as in the frame or joints of the device. The combination of these two material types allows for the creation of lightweight yet robust orthotics that can withstand daily use while providing necessary support and mobility.

Other material combinations, while potentially useful in specific applications, may not offer the same blend of characteristics that optimize functionality and patient comfort as effectively as the plastics and metal pairing.
