[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 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. [Available Sizes for Finger Joints] Size S: Finger circumference below 5.5 cm (2.2 inches). Size M: Finger circumference 5.5–7 cm (2.2–2.8 inches). Size L: Finger circumference above 7 cm (2.8 inches). Choose from three sizes to fit your finger joint. 1. Coil Spring Design: The finger extension splint features a coiled spring that provides dynamic extension while allowing active flexion. Coil springs are positioned on both sides of the PIP joint for balanced support and strength. 2. Usage: Suitable for joint extension dysfunction due to various causes. 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 Mechanism: Utilizes the elastic force of the spring to straighten and stabilize the finger. Allows controlled finger flexion against spring resistance for rehabilitation purposes. Material: EVA and stainless steel. Intended Use: Suitable for limited finger extension or flexion following finger injury or chronic arthritis. Applications: Sprained fingers, fracture stabilization, underextended fingers, mallet finger, tendon injuries, and related conditions. Dimensions: Size S: Fits finger circumference below 5.5 cm (2.2 inches) Size M: Fits finger circumference 5.5–7 cm (2.2–2.8 inches) Size L: Fits finger circumference above 7 cm (2.8 inches)
