[Support and Stabilize]: The finger splint effectively straightens and immobilizes the full finger knuckles while protecting the finger and thumb joints. [Indications for Use]: The finger extension splint helps reduce tightness of PIP joints, flexion contractures, and boutonniere deformities; maintains assisted extension at PIP joints while allowing active flexion. It can be used for soft tissue injuries affecting PIP joints and possible flexion deformities. [All Sizes of Finger Joints]: Size S: Indicates circumference below 5.5 cm. Size M: Indicates finger circumference 5.5–7 cm. Size L: Indicates circumference above 7 cm. Choose from 3 sizes to fit your finger joint size. 1. Coil Spring Design: The finger extension splint features a coiled spring that provides dynamic extension while allowing active flexion. The coil springs are placed on both sides of the PIP joint for balance and strength. 2. Usage: Suitable for various causes of joint extension dysfunction. 3. Practical Support: Designed for PIP joint flexion contracture. Provides support to the MP joint. 4. Soft EVA Pads: Curved proximal and distal pads distribute pressure evenly for enhanced comfort. 5. Spring Coil Extension Splint: Utilizes the elastic force of the spring to straighten and stabilize the finger. Allows strong finger flexion against spring resistance for rehabilitation purposes. Material: EVA + stainless steel Scope of Application: Suitable for insufficient straightening or bending of fingers following finger injury or long-term arthritis. Applications: Sprained fingers, fracture fixation, underextended fingers, mallet fingers, tendon ruptures, and similar conditions. Dimensions: Size S: Circumference below 5.5 cm (2.2 inches) Size M: Finger circumference 5.5–7 cm (2.2–2.8 inches) Size L: Circumference above 7 cm (2.8 inches)
