Beyond plaster

Unlike most plaster casts, which must remain dry, many orthotic fabrication materials are designed to be water-resistant, allowing users to get in the water without compromising the immobilization of their injury. This feature is especially beneficial for children and adults who want to maintain an active lifestyle (in the water), even when dealing with an injury.

Moreover, these materials are often perforated, making them breathable. This breathability ensures better airflow around the injured area, reducing the risk of skin irritation and infections that can occur with traditional plaster casts.

Additionally, orthoses can be cleaned, either by hand using lukewarm water and dish detergent or even in a washing machine on a cold water cycle, enhancing hygiene and making them a cleaner option for long-term use. 

Perhaps the most notable and significant difference between these immobilization with plaster casts versus low temperature thermoplastic materials is in the course of rehabilitation.

A removable thermoplastic orthosis allows for immediate skin care and commencement of active range of movement exercises, and other rehabilitation strategies, as soon as it is safe and clinically appropriate.

This can lead to a decrease in the number of therapy sessions required by the patient: those able to commence early mobilization needed an average of only 6.57 sessions, versus 17 sessions when mobilization was delayed.

When comparing early mobilization versus delayed mobilization, research has found statistically significant differences n favor of early mobilization with regards to increased patient compliance to rehabilitation, faster return to normal function, superior grip strength, and improved wrist range of movement.
