FlexiCast Short Thumb Spica Immobilizer

NHD FlexiCast is the first of its kind - an orthopedic immobilizer that has the rigidity to hold the fractured part as well as ensure proper skin ventilation. FlexiCast comes as an easy-to-fix wearable material on the injured part. After wearing, light treatment completes the curing process and makes the FlexiCast rigid. This process is quick and only takes 3-10 minutes, depending on the size of the FlexiCast immobilizer. After the course of therapy, FlexiCast can be removed without the use of any other external cast cutter or spreader.

The design and the material of FlexiCast are engineered to provide superior comfort to the patient. A foam, which is in contact with the skin, is bio-compatible (ISO 10993-10 certified) and provides cushioning against the hardened polymer. The FlexiCast immobilizer is designed in such a way that the intermittent hollow spaces facilitate the circulation of air and evaporation of sweat or water from the skin surface.

NHD FlexiCast is only available for medical professionals at this time. If you are interested in purchasing FlexiCast for your practice, please click below to reach out to one of our NHD sales reps.

FlexiCast Thumb Spica immobilizers are designed for the immobilization of the thumb. It has an inbuilt soft hook and loop fastener which is very comfortable for skin contact. It is used to provide support for thumb injuries (ligament instability, sprain, or muscle strain), gamekeeper’s thumb, De Quervain’s syndrome, or fractures of the Scaphoid or first metacarpal. Doctors need 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 the immobilizer until it gets rigid.


  • Scaphoid fracture – seen or suspected
  • De Quervain tenosynovitis / other ligamentous or soft tissue injuries to the thumb
  • Non-angulated, non-displaced, extra-articular fractures at the base of the first metacarpal
