Ulnar Gutter Immobilizer

FlexiOH® Ulnar Gutter Immobilizers are designed for immobilization of metacarpals and phalanges. It has an inbuilt soft cushioning padding which is very comfortable for skin contact. It is used to provide support for fingers injuries (ligament instability, sprain or muscle strain), fractures through the neck of the fifth metacarpal. HCP needs to apply it on the patient’s hand and then cure it with the RizyCure® light device (recommended) or direct sunlight for around 3-5 minutes depending on the size of immobilizer, until it gets rigid.

FlexiOH® Ulnar Gutter Immobilizer comes in 4 different sizes: S, M L and XL. All of the immobilizers vary in terms of wrist circumference, forearm circumference and finger length. For the best fit of FlexiOH® Ulnar Gutter Immobilizer, taking the measurement of the patient’s hand is necessary before application.
