Our Orfit blog shares information and instructions in matching our thermoplastic materials to orthotic designs.
Please check back frequently to gain inspiration and ideas in orthotic fabrication for all of your patient’s needs.
Splint Design: Comfortable and lightweight orthoses with Orfilight materials
Objectives of the Splint: Positioning for rest and support and relief of symptoms
Pathology: All pathologies that would benefit from a lightweight support
When patients are required to wear their orthoses for long duration during day and night, it is always helpful to consider the size of the patient’s extremity, the specifics of the diagnosis and the weight of the selected material for the orthosis. Orfit Industries offers an extremely lightweight material that might be appropriate for many of your patients, regardless of the specific diagnosis.
The comfort of the finished orthosis is obtained by the lightness of the splint, the contact with the material, and the absence of sweating.
Compare the weight of any orthosis in your clinic to the weight of an orthosis fabricated from Orfilight. A volar wrist orthosis might weigh only 46 grams!
All three colors are available in 3 thicknesses with multiple perforation patterns to allow for any orthotic design and any size configuration.
Consider an orthosis for the diagnosis of Carpal Tunnel Syndrome
Carpal tunnel syndrome is a condition where pressure on the median nerve in the carpal tunnel causes symptoms of pain and paresthesias. Studies have shown that there is less pressure in the carpal tunnel when the wrist sits in a neutral position. Orthoses that maintain this wrist position are effective at relieving symptoms with 70 % good results after less than 3 months of wearing.
Since the recommended wearing schedule for the patient is to sleep with the splint on during the night to avoid the wrist flexion, it must be very comfortable to ensure the patient’s compliance. Also, the CTS diagnosis is more common in females and therefore the orthosis must be lightweight and comfortable.
Extreme comfort can be obtained by using Orfilight, Orfilight Black NS and/ or the new Orfilight Atomic Blue NS due to the lightness and foaminess of this material. Patients may actually perspire less with these orthoses!
The orthosis is molded with the wrist in neutral position, with no flexion or extension.
The Velcro straps are placed with the one in the middle somewhat wider than others: the pressure is always greater in the middle of the orthosis than at the distal and proximal ends.
The thermoplastic surface is not completely smooth, which allows air to circulate between the skin and the orthotic, which may help prevent perspiration.
This thermoplastic material is self-adhesive, even when heated with water, and slowly stretchable. So you can use these properties to help you molding with a “third hand” as shown underneath.
The edges are easy to smooth by cutting and require no edging strip on them.
The thumb doesn’t need to be immobilized in this diagnosis.
It is recommended that the patient wears this orthosis during the night, for a period of at least 3 months, but most of the time, the paresthesia will disappear before.
Sometimes it is recommended to wear the orthosis during the day as well depending on the severity of the symptoms.
Orfilight is available in 3 different materials:
- Orfilight Black NS
- Orfilight Atomic Blue NS
