Thermoplastic Splints Can Melt!
Thermoplastic is heated in hot water to create a flexible material for moulding custom splints, it then sets hard to support your hand or finger.
This makes it a great material to get the perfect fit and customisation for splinting as well as remoulding as your recovery progresses. But if left in the sun or a hot car the heat can melt the plastic and deform your splint. The melting temperature of thermoplastic is 70 degrees, the inside of a car, especially in direct sunlight, will exceed this.
It is important then you care for your splint when not wearing it to prolong its life. Deformed splint will need to be remoulded for correct fitting and splinting for your injury or condition. If serve cases the splint may even need to be completly remade.
If you splint does become deformed, please contact the clinic as soon as possible to organise an appointment for the splint to be remoulded.
