The small joints of the fingers have a complex arrangement of bones, ligaments, tissues and tendons that provide movement and stability. Anything that disrupts this arrangement can cause the finger to lose motion and cause a contracture. Fractures, ligament injuries, and arthritic changes are some of the more common causes of contractures. Even a small amount of swelling or scar tissue can block joint motion and lead to a contracture.
A contracture is a loss of motion in the finger, whether into flexion (bending towards the palm) or extension (straightening away from the palm) if the joint cannot be made to move passively (using outside force) through its full range of motion.
The 3pp Final Flexion Wrap is often recommended to restore the final degrees of flexion that cannot be achieved through a custom-made hand splint. The 3pp Final Flexion Wrap allows the wearer to adjust the force to tolerance for fast, successful treatment. Comfortable foam-lined material distributes pressure evenly and holds the 3pp Final Flexion Wrap in place.
Oval-8 splints are recommended as a "retainer" after a dynamic splinting program has restored PIP or DIP extension. Using the Oval-8 for day and or nighttime wear helps maintain the correction and prevents the contracture from reoccurring
