AliMed Dynamic Digit Extensor Tube

More About This Product

AliMed Dynamic Digit Extensor Tube is the better way to reduce PIP and DIP joint finger flexion contractures. A curved, banana-shaped, neoprene tube locates a 30 reverse angle under the PIP joint, stimulating a spring-like mechanism. Distributes lift along the entire volar surface of the digit. This lift, combined with a constrictive factor at the distal end of the digit, eliminates the harmful pressure commonly experienced with other forms of extension splinting. Fabric interior, rubber exterior.

Fights edema Unlike traditional spring and jack-like devices, tube fits snugly around the digit, delivering warmth to help relax tight tendinous structures and remodel scar tissue. Circumferential pressure aids in restricting fluid to assist in edema reduction.

Trim to length The splint is mildly flexible, maintaining joint mobility and some functional use of the digit. Can be easily trimmed to length and contoured to fit the web space.

Easy application Fabric interior makes the tube easy to slip on and adds durability. Rubber exterior provides a grip surface to aid in application as well as a functional grip surface during daily activities.

No pressure points
Tube may be worn for longer periods of time compared to other extension splints, due to its gentle force and distribution of pressure over a large area.

Clinically proven: Clinical tests have demonstrated superior performance compared to other extension devices, even showing success in digits that were unsuccessfully treated by other clinical means.*

Dynamic Digit Extensor Tube

Principal Use/Application: Reduce PIP joint flexion contractures associated with acute injuries (such as sports injury sprains or postsurgical repair of the PIP joint).

Secondary Use/Application: Offset constant positioning of fingers in PIP flexion as seen in spinal cord injury at the level of C7 or higher.

Primary Diagnostic Group: Patients with post-acute injury to the hand when a flexion contracture has formed at the PIP joint.

Advantages: Easy to apply, comfortable to wear for long periods of time. Can be trimmed at either end to achieve custom fit. Effective without being tight.
