We created a Practical Guide to Finger Orthoses that covers five different orthoses for finger conditions using Orficast 3 cm (1”).
The smallest member of the Orficast family is a great product for the fabrication of a variety of finger orthoses. But did you ever stop to think about the simplicity of it? As a matter of fact, using only 20 cm (8”) of length of this product, you can fabricate various effective orthoses with simple designs!
In the Practical Guide to Finger Orthoses we will:
Here’s a preview of one of the orthoses in the guide.
The proximal interphalangeal (PIP) joint is the most commonly injured joint in the hand and highly susceptible to injury during athletic activities, especially in ball-handling sports.
Angular forces may cause a partial or a complete rupture in the collateral ligaments, and lateral dislocation can occur when combined with a volar plate rupture. In general, the PIP joint is prone to stiffness after injury, and if it is not properly diagnosed and treated, a permanent impairment of the hand function may result.
Protective motion allows the PIP joint to move through its range of motion while keeping the joint stable. The goal is to restore motion as soon as possible to prevent stiffness and contracture. A common method used for most stable injuries is buddy strapping or taping.
Step 1: Take two 20 cm (8″) long strips of Orficast 3 cm (1″). Fold the strips lengthwise after activation, or roll longitudinally.
Step 2: Wrap one strip proximally around the proximal phalanx of one finger and secure it to itself like a ring.
Step 3: Wrap the orthosis around the adjacent finger and secure it back to itself. It forms the shape of the number 8. Then, let it harden.
Step 4: Finally, repeat steps 3 and 4 with the second strip of Orficast. Position it across the middle phalanx so that the PIP joint is free between the two buddy tapes.
