Abstract

Embodiments of the inventive concepts disclosed herein are directed to an angular digital device for joint deformity or imbalance. A device formed from a dense soft material shaped to fit a digit with straight segments and angled transitions at the interphalangeal joint levels such that rotational force(s) are created at the joint line(s). Additionally, an ‘open transition’ design with a dorsal strap element is described, and a design with an additional moldable, semi-rigid component added. A retention strap is described to prevent the splint from migrating off during sleep.

Claims (18)

1. A device configured to produce one or more rotational forces at the interphalangeal joints of a digit, the device comprising:

two or more straight, tubular segments of stretchable material configured to fit the digit, wherein at least one angular transition between the two or more straight, tubular segments is configured to produce rotational forces when the device is applied over the digit; and

a removable strap configured to secure the device to an appendage, wherein the removable strap further comprises:

a first attaching element at a first end thereof to secure the removable strap to one of the two or more straight, tubular segments, wherein the removable strap then wraps diagonally and proximally from the digit to then circumferentially wrap a wrist; and

a second attaching element to secure the removable strap to itself proximate the wrist.

2. A device configured to produce one or more rotational forces at the interphalangeal joints of a digit, the device comprising:

two or more straight, tubular segments of stretchable material configured to fit the digit, wherein at least one angular transition between the two or more straight, tubular segments is configured to produce rotational forces when the device is applied over the digit; and

a malleable, angled element configured to modify the rotational force at one or more of the interphalangeal joints.

3. A device configured to produce one or more rotational forces at one or more interphalangeal joints of a digit, the device comprising:

two or more straight, tubular segments of stretchable material configured to the digit;

an opening in one of the one or more straight, tubular segments wherein after placement on the digit, a connecting element between the two or more straight, tubular segments is secured across the opening to produce the one or more rotational forces; and

a malleable, angled element configured to modify the one or more rotational forces at one or more of the one or more interphalangeal joints.

4. A device configured to produce one or more rotational forces at one or more interphalangeal joints of a digit, the device comprising:

two or more straight, tubular segments of stretchable material configured to the digit;

an opening in one of the one or more straight, tubular segments wherein after placement on the digit, a connecting element between the two or more straight, tubular segments is secured across the opening to produce the one or more rotational forces; and

a removable strap configured to secure the device to an appendage, wherein the removable strap further comprises:

a first attaching element at a first end thereof to secure the removable strap to one of the two or more straight, tubular segments, wherein the removable strap then wraps diagonally and proximally from the digit to then circumferentially wrap a wrist; and

a second attaching element to secure the removable strap to itself proximate the wrist.
